Astonishing Diversity of Somatic Ciliary Patterns in Oligotrichid<br />

Ciliates (Protista, Ciliophora)<br />

Agatha, S.<br />

Dept. Organismic Biology, University of Salzburg, Hellbrunnerstrasse 34, A-5020 Salzburg,<br />

e-mail: sabine.agatha@sbg.ac.at<br />

Although the Oligotrichida (Ciliophora, Spirotricha) typically possess only two somatic ciliary rows, the<br />

diversity of ciliary patterns is tremendous, i.e., eleven, occasionally very complicated arrangements<br />

are distinguished. The evolution of these somatic ciliary patterns is reconstructed, using the orientation<br />

of the ciliary rows (which of the paired basal bodies bears the cilium) and the position of the oral<br />

primordium, the developing oral ciliature of the daughter cell. Even though molecular phylogenies are<br />

still in their infancies concerning the oligotrichids, the genealogy of the small subunit ribosomal RNA<br />

gene sequences is congruent with the current hypothesis. It is most parsimonious to assume a<br />

convergent pattern development in the tailless taxa and the tailed tontoniids, as the contractile tail is<br />

considered a strong synapomorphy due to its complex and unique ultrastructure. Indeed, ontogenetic<br />

data suggest that the Ω-shaped pattern evolved not only convergently in the tailed and tailless taxa,<br />

but also originated from different patterns. On the other hand, gene sequence data indicate that the<br />

sinistrally spiralled arrangement did not develop twice, but represents a synapomorphy of the tailed<br />

genus Spirotontonia Agatha, 2004 and the secondarily tailless monotypic genus Laboea Lohmann,<br />

1908. The curious genera Apostrombidium Xu et al., 2009 and Varistrombidium Xu et al., 2009 were<br />

intuitively affiliated with the strombidiids. The present concept corroborates this assignment and<br />

proposes a position for the two genera within the family Strombidiidae. Furthermore, new ontogenetic<br />

data necessitate a split of the species-rich genus Strombidium. While the oral primordium forms<br />

posteriorly to the horizontal ciliary row in the type species of Strombidium, it develops anteriorly in<br />

three congeners, justifying the establishment of two new genera, which differ in the arrangement of<br />

their extrusomes (extrusive organelles): they insert along the anterior margin of the horizontal ciliary<br />

row and posteriorly to the oral primordium in one genus, while distinctly apart from the ciliary row and<br />

anteriorly to the oral primordium in the other; probably, both patterns evolved convergently (Agatha<br />

<strong>2010</strong>).<br />

“Do you know EDIT, CETAF, DEST, EJT, EoL and so on?”<br />

Initiatives for the promotion of taxonomy on a European level.<br />

Aubrecht, G.<br />

Biology Centre of the Upper <strong>Austria</strong>n State Museums, J.-W.-Klein-Straße 73, 4040 Linz, <strong>Austria</strong>,<br />

e-mail: g.aubrecht@landesmuseum.at<br />

The Darwin Declaration 1998 referring to the „taxonomic impediment“ started highlighting the global<br />

problems of taxonomic research. Calls for help and for improvement of this bad situation from museum<br />

and university taxonomists are already commonplace nationally and internationally.<br />

Usually taxonomists are organized in their specific scientific societies, but it needs concerted<br />

communication and action on a much broader base to be heard politically. The recent improvement of<br />

communication and organization among taxonomists must not hide the fact that operative actions are<br />

needed in order to reverse the fatal situation.<br />

The „Global Taxonomy Initiative – GTI“ is an intergovernmental project within the Biodiversity<br />

Convention and was ratified in 200<strong>2.</strong> Thus the problem was outlined and set into an institutional<br />

framework. But it did not yet bring a measureable improvement of the situation. New projects were<br />

initiated but especially the education of taxonomists at university and non-university level is still<br />

decreasing rapidly. This fact is really threatening and still unsolved. The foundation of <strong>NOBIS</strong>-<strong>Austria</strong><br />

was an initiative on the national level with the aim of improving communication between <strong>Austria</strong>n<br />

taxonomists, of strengthening group dynamics and of offering a joint approach to the public.<br />

Here some international projects are introduced concerning the wider frame of taxonomy. These might<br />

be of interest because project proposals often need a view an a broad scale. Recent projects are for<br />

example EDIT (European Distributed Institute of Taxonomy), CETAF (Consortium European<br />

Taxonomic Facilities), DEST (Distributed European School of Taxonomy), EJT (European Journal of<br />

Taxonomy), EoL (Encyclopedia of Life), etc.<br />

Both national and international approaches will be necessary in the future in order to promote the legal<br />

concerns of taxonomists and to find political acceptance.<br />

Long-distance travels with short-lived larvae – the peculiarities<br />

of seamount bryozoans<br />

In the intensified effort to study seamount biota during the last decade, the Bryozoa have almost<br />

completely been neglected, although they may form a major component of the sessile benthic<br />

community. A first screening of the sparse literature and some of the samples taken during several<br />

scientific cruises shows that cheilostome bryozoans are regularly found on NE Atlantic seamounts: 36<br />

spp. on Gettysburg Smt, 27 on the Great Meteor Bank (GMB), 24 on Ampère Smt, 23 on Atlantis Smt,<br />

21 on Hyères Smt, 14 on Irving Smt, and 13 on Conception Smt.<br />

Due to the short-lived bryozoan larvae, dispersal is generally very restricted and long-distance<br />

transport of bryozoans to or between isolated offshore sites presumably only achieved by means of<br />

rafting of the colony. However, this mechanism is less likely for species adapted to bathyal habitats.<br />

Endemism, particularly on remote seamounts, is therefore expected to be comparatively high. Indeed,<br />

at least 18 of the 27 spp. (67%) found on the GMB are endemic to this seamount. Of the remaining<br />

species, one arrived on Sargassum from the W Atlantic, three species are known from the E Atlantic<br />

shelf, and another five are restricted to the Azores and other Atlantic seamounts. Moreover, at least 17<br />

species, three genera and one family from the GMB are new to science.<br />

Regarding the entire region, several higher taxa are endemic to seamounts, or are significantly more<br />

speciose there than on the continental shelf, indicating a long history of seamount faunas and,<br />

possibly, sporadic dispersal of founder species from seamounts to the shelf.<br />

Given the number of scientific cruises to these and other NE Atlantic seamounts, and the great<br />

amount of unscreened samples that exist, a thorough taxonomic study of seamount bryozoans will<br />

certainly increase the number of taxa. With this knowledge it will then be possible to address more<br />

precise questions concerning the ecology, biogeographic patterns and processes, and the<br />

evolutionary history of seamount faunas.<br />

Lichenized Fungi diversity of the Balkan Peninsula<br />

Bilovitz, P.O. & Mayrhofer, H.<br />

Institut für Pflanzenwissenschaften, Karl-Franzens-Universität Graz, Holteigasse 6, 8010 Graz, e-<br />

mails: pe.bilovitz@uni-graz.at, helmut.mayrhofer@uni-graz.at<br />

The present knowledge of lichenized fungi of the Balkan Peninsula is still rather incomplete and there<br />

are relatively few recent floristic papers. While numerous lichen collections from coastal parts revealed<br />

a lot of new species towards the end of Habsburg period and several important studies were published<br />

between World War I and World War II by the lichenologists F. Kušan, A. Popnikolov, M. Servít, J.<br />

Suza and Ö. Szatala, lichenological exploration of former Yugoslavia was interrupted almost<br />

completely in the period between World War II and the segregation of nations in the 1990s. In the<br />

1970s first steps were undertaken to revitalize the lichenological investigation of the Dinaric region by<br />

J. Poelt and his students in Graz resulting in the description of several new species as well as by the<br />

Czech lichenologist A. Vežda and the Slovak lichenologist I. Pišút. In the late 1970s and early 1980s it<br />

was M. Murati, who published a series of floristic papers on the lichen flora of Macedonia. During the<br />

last twenty years H. Mayrhofer (Graz), his students and collaborators intensified lichenological<br />

activities on the Balkan Peninsula by establishing co-operations with local biologists, starting with<br />

floristic papers, followed by catalogues of lichens and lichenicolous fungi of Slovenia (2000), Bulgaria<br />

(2005), Montenegro (2009), Bosnia & Herzegovina (in press) and Macedonia (in prep.).<br />

The area of the southern Dinaric mountains with its glacial refugia is highly attractive for biodiversity<br />

studies, because it represents one of the last remaining large virgin forest areas in Europe (e.g.<br />

Biogradska gora in Montenegro and Perućica in Bosnia & Herzegovina). These maintain a rich<br />

diversity of lichens, comprising many elsewhere rarely found oceanic species.<br />

Actual investigations are focusing on population genetics of Lobaria pulmonaria in and around virgin<br />

forests, its fungi on large decaying thalli, on the general biodiversity of remote or otherwise interesting<br />

sites and ecological niches with special emphasis on Bosnia & Herzegovina, Bulgaria, Macedonia,<br />

Montenegro and Slovenia, and on the taxonomy and distribution of the family Physciaceae.<br />

Today, Greece (incl. Crete) has a known diversity of c. 1200 lichen species, Slovenia, Croatia and<br />

Bulgaria c. 1000 each, Montenegro c. 700, Bosnia & Herzegovina, Serbia (incl. Kosova) and<br />

Macedonia c. 600 each and Albania c. 200(!).<br />

How and why to achieve more objectivity in taxonomy,<br />

exemplified on a fossil ostracod from long-lived Lake Pannon<br />

Taxonomists are commonly confronted with poor descriptions. The situation is exacerbated for fossil<br />

taxa which display few homologue landmarks useful for defining morphological traits. These latter are<br />

either necessary for building a clear taxonomic diagnosis or for further phylogenetic analysis.<br />

Amplocypris abscissa was briefly described by A. E. Reuss (1850) from several outcrops near Vienna<br />

and Sopron (Vienna Basin; Upper Miocene, Pannonian). Subsequently, it was mentioned all around<br />

the Pannonian Basin respectively the Palaeo-Lake Pannon, which covered this area at that time: from<br />

the western sites in <strong>Austria</strong> and Slovakia, to eastern and southern ones (Romania, Serbia and<br />

Croatia). This geographic distribution contrasts with the high number of fossil species belonging to this<br />

genus, which are considered to be endemic in Lake Pannon. Our project on fossil ostracods from<br />

Hennersdorf (Vienna Basin, Pannonian “D”) document A. abscissa as a polymorphic taxon. Moreover<br />

the genus Amplocypris Zalanyi 1944, displays an elusive diagnosis and an unsecured phylogenetic<br />

position. We demonstrate, using a precise protocol, how the taxonomic status of both of the genus<br />

Amplocypris and of the species A. abscissa can be achieved in an accurate and reproducible way: (a)<br />

A comparative morphological study of the valves, for fossil Amplocypris species and Recent<br />

representatives of genera belonging to higher-rank taxa, using both TL- and SE-microscopy, is<br />

absolutely necessary for developing a clear differential diagnosis of this genus and its allocation to one<br />

of the Cyprididae subfamilies (i.e. the Eucypridinae). (b) Amplocypris displays few homologue<br />

landmarks. Geometric morphometrics for outlines, combined with an original algorithm, which<br />

resemble a semi-landmark approach, offers the possibility to create morphological traits: Linhart’s B-<br />

spline Approach (cf. the web site “Methods in Ostracodology” at http://palstrat.uni-graz.at). (c) Data<br />

expressed as pair-wise resemblance matrix of Euclidean distances are further analysed using<br />

techniques specific to numerical taxonomy, like UPGMA-cluster analysis, Principal coordinate analysis<br />

and the SIMPER exploratory analysis (cf. the computer package PRIMER v6 and PERMANOVA+ for<br />

PRIMER). (d) A matrix of dissimilarity values of the traits, expressed as arithmetic means with their<br />

99% CL, allow to produce a new diagnosis of A. abscissa and to separate it from two other unnamed<br />

taxa. Together they form a phylogenetic lineage.<br />

Habitat requirements of the pulmonate land snails Trochulus<br />

oreinos oreinos and Cylindrus obtusus endemic to the Northern<br />

Calcareous Alps, <strong>Austria</strong><br />

Duda, M., Kruckenhauser, L., Haring, E., Harl, J. & Sattmann, H.<br />

Natural History Museum Vienna, Bugring 7, A-1010 Vienna, e-mail: michael.duda@nhm-wien.ac.at<br />

The <strong>Austria</strong>n endemic land snails Trochulus oreinos oreinos (Wagner 1915) and Cylindrus obtusus<br />

(Draparnaud 1805) have been in the focus of phylogenetic research in the course of our project about<br />

<strong>Austria</strong>n land snails. For T. oreinos, which was formerly regarded as a local subspecies of the wide-<br />

spread T. hispidus, a first phylogenetic analysis combined with more detailed morphological<br />

investigations was performed recently indicating that T. oreinos is an old phylogenetic lineage and<br />

presumably has a long independent history in the North-Eastern Calcareous Alps. Cylindrus obtusus,<br />

which is an old distinct lineage within the Helicidae, is – like T. oreinos - restricted to high elevations of<br />

the Eastern Alps. In its easternmost populations it shows some specific morphological traits, as a<br />

somewhat smaller size and irregular building of mucus glands.<br />

In this study we wanted to know, if these findings are also reflected in the habitat preferences of these<br />

species. Four sites, which mark the easternmost distribution border of both species, where selected<br />

for further investigation: the mountains Hochschwab, Schneealpe, Rax and Schneeberg. From these<br />

areas we had an adequate sample and exact vegetation maps were available.<br />

In C. obusus, the morphological specialties of the easternmost populations are perhaps a result of the<br />

suboptimal climatic conditions on Rax and Schneeberg Mountain. Both massifs are under strong<br />

influence of the warm pannonic climate, which might afflict this cryophilic species. C. obtusus and T.<br />

oreinos prefer rocky habitats from the subalpine ecotone upwards. While T. oreinos is restricted to<br />

loose Caricetum firmae meadow and alpine boulder and scree societies, C. obtusus can inhabit<br />

several plant communities. Both species are restricted to primarily forest free sites on rocky ground or<br />

thin layer of rentsina soil. Therefore they are not afflicted by abandoning of man-made meadows, the<br />

most important recent change of alpine agriculture. As both taxa are restricted to the subalpine and<br />

alpine ecotone, at least populations at the lower altitudinal distribution are potentially afflicted by<br />

climatic changes<br />

Protists as bioindicators for soil quality<br />

Foissner, W.<br />

Universität Salzburg, FB Organismische Biologie, Hellbrunner Strasse 34, A-5020 Salzburg<br />

Several unique features favour the use of heterotrophic protozoa as bioindicators for soil quality:<br />

1. Protozoa are an essential component of soil ecosystems, because of their large standing crop and<br />

production. Changes in their dynamics and community structure very probably influence the rate<br />

and kind of soil formation and soil fertility.<br />

<strong>2.</strong> Protozoa, with their rapid growth and delicate external membranes, can react more quickly to<br />

environmental changes than any other eukaryotic organism and can thus serve as an early<br />

warning system.<br />

<strong>3.</strong> The eukaryotic genome of the protozoa is similar to that of the metazoa. Their reactions to<br />

environmental changes can thus be related to higher organisms more convincingly than those of<br />

prokaryotes.<br />

<strong>4.</strong> Protozoa inhabit and are particularly abundant in those soil ecosystems that almost or entirely lack<br />

higher organisms due to extreme environmental conditions, e.g. alpine regions above the<br />

timberline, Arctic and Antarctic biotopes.<br />

5. Protozoa are not readily dislodged in soil (Kuikman et al., 1990). Many (but not all!) are ubiquitous<br />

and are useful in comparing results from different regions. Differences in patterns of distribution are<br />

almost entirely restricted to passive vertical displacement; thus, the difficult problem, especially<br />

with the epigaeon, of horizontal migration does not affect the investigations.<br />

There are, however, several factors that have apparently restricted the use of soil protozoa and even<br />

metazoa as bioindicators (Aescht and Foissner, 1992):<br />

1. The immense number of species; more than 1000 may occur in a square metre of forest soil. Many<br />

specialists are needed for identification and each species has specific requirements that are often<br />

incompletely known.<br />

<strong>2.</strong> Enumeration of soil organisms is difficult and time-consuming.<br />

<strong>3.</strong> Animals need other organisms for food. Thus, the constellation of factors is more complex than in<br />

plants and bioindication often remains un-specific, i.e. different factors induce similar reactions.<br />

<strong>4.</strong> Most soil organisms are inconspicuous and invisible to the naked eye, making them unattractive to<br />

many potential investigators.<br />

In the lecture, I show examples from comparisons of ecofarmed and conventionally farmed fields and<br />

grasslands.<br />

Phylogeography and synchronous diversification of the Corvus<br />

corvids of the world<br />

Gamauf, A. 1 , Däubl, B. 1 , Kryukov, A. 2 , Pinsker, W. 1 & Haring, E. 1<br />

1 Museum of Natural History Vienna, Dept. Vertebrate Zoology, Burgring 7, A-1010 Vienna, <strong>Austria</strong>;<br />

elisabeth.haring@nhm-wien.ac.at<br />

2 Institute of Biology and Soil Science, Russian Academy of Sciences, Vladivostok 690022, Russia.<br />

The genus Corvus with its approximately 40 species is world wide distributed, except S America.<br />

Highest diversity is found in Australasia and SE Asian islands. Ten species (25%) are coloured black<br />

and white/grey, the rest are completely black.<br />

We investigated the phylogeny of the genus Corvus employing DNA sequences of the mitochondrial<br />

control region. The study was based mainly on museum material allowing the analysis of more than 30<br />

species. Inclusion of sequences of other corvid genera as available in GenBank confirmed the<br />

monophyly of the genus Corvus. Within the Corvus clade several distinct subclades can be<br />

distinguished. Some contain only single species or species pairs (e.g., C. monedula + C. dauricus; C.<br />

frugilegus; C. palmarum) while other clades are composed of many species (e.g., the Holarctic and<br />

African clade or the SE and E Asian clade). In general, the composition of the clades reflects<br />

geographic contiguousness. The basal relationships among clades remain unresolved with this marker<br />

sequence.<br />

It is remarkable that each clade contains black as well as white/grey coloured representatives. None of<br />

the latter are found in N America, whereas almost all African species south of the Sahara show black-<br />

white pattern. The most parsimonious explanation for the distribution of plumage colour in the<br />

phylogenetic tree is that the pale markings evolved at least five times independently. The assumption<br />

that the white/grey colour pattern - which is found also in other genera of the family Corvidae, e.g.,<br />

Pica - is the plesiomorphic state, is less likely.<br />

Crypitc diversity in European Gentianella section Gentianella<br />

(Gentianaceae)<br />

Greimler, J.<br />

Systematic and Evolutionary Botany, Faculty Center Botany, University of Vienna, A-1030 Vienna,<br />

Rennweg 14, <strong>Austria</strong><br />

Gentianella section Gentianella (Gentianeae, Swertiinae) includes ca. 20 taxa in Europe of which the<br />

majority is found in and around the Alps. Most taxa are highly variable due to ecological polymorphism<br />

among populations in different habitats and in part due to seasonal dimorphism. Investigations from<br />

reproductive biology, common garden experiments, morphology, nrDNA, cpDNA, and AFLP have<br />

revealed various patterns of divergence and in some cases disagreement between genetic and<br />

morphological data.<br />

Genetic data (AFLP) in contrast to morphology indicate clear differentiation into two cryptic species<br />

within the widespread G. germanica agg. resulting in G. rhaetica in the Eastern Alps and G. germanica<br />

s.str. in northern Central Europe. These allopatric cryptic or sibling species appear to have been<br />

separated by Pleistocene climatic oscillations. Extensive patterns of haplotype sharing were observed<br />

in the cpDNA RFLP data. Both hybridization or introgresion as well as incomplete lineage sorting can<br />

generate such patterns. It is, however, difficult to distinguish between these two processes. In the<br />

case of Gentianella reticulate evolution (introgression) may explain such patterns to a high degree as<br />

well as the often found morphological uncertainties or gradients on range margins of severeal taxa.<br />

AFLP data provided evidence for various scenarios of introgression and reticulate evolution among G.<br />

rhaetica, G. obtusifolia, and G. austriaca in the eastern Alps. Such reticulate patterns and/or ancient<br />

polymorphism towards southeastern Europe may be the reason for unclear relationships within G.<br />

austriaca agg. and its relation to other taxa especially in south-eastern Europe. The significance of<br />

those various cryptic patterns for conservation is discussed.<br />

Per se taxonomic investigations of fossils can neither include molecular biological approaches nor the<br />

study of soft parts. Environmental parameters cannot be measured directly. Consequently, the<br />

palaeontological approach is strictly morphologically-based and environmental factors must be<br />

deduced from abiotic and biotic proxies. However, the fossil record has one striking advantage over<br />

the study of extant organisms: time! If an appropriate time-model is on hand, long- as well as short-<br />

term changes (millions of years, down to years) can be extracted. Especially, micro-fossils are of<br />

prime importance in this case. Due to their small size, ten thousands of preserved remains provide a<br />

huge dataset for profound taxonomic analyses and phylogenetical reconstructions.<br />

The examination of a limnic–deltaic sedimentary sequence, deposited on the western margin of<br />

Palaeo-Ancient Lake Pannon (~11.3 Ma), focused on the occurrence of the mussel shrimp genus<br />

Cyprideis (ostracoda) and its linkage to environmental shifts. Based on the timing of the section, we<br />

achieved by our high-resolution sampling (5 mm thick rock slices) a time-resolution of only a few<br />

years. Qualitative as well as linear and geometric morphometric valve analyses allowed differentiating<br />

three co-occurring Cyprideis species, which were probably adapted to different microhabitats. One of<br />

them is only recognized at the peak of a limnic transgression. In contrast, one other species seems to<br />

be more euryplastic because it appears well before this event and is recorded in the regressive<br />

prodelta sediments up section likewise. The remarkable low quantity of the third species clearly<br />

reflects its diverging paleoecological demands, since it mainly occurs in the littoral facies. Size,<br />

posteroventral spines, hinge structure, ornamentation and valve outline turned out to be appropriate<br />

diagnostic characters to define these sympatric species in the sense of a multidimensional species<br />

concept. These characters enable to delineate Cyprideis populations in Lake Pannon as segments of<br />

evolutionary lineages and thus phylogenetic species. This is essential for any well-founded<br />

biostratigraphic zonation and further palaeogeographic models.<br />

This is a contribution to the FWF-project P 21748-N21.<br />

Digenetic trematodes comprise numerous species of great medical and veterinary importance. These<br />

parasites have complicated life cycles with multiple successive hosts. The introduced large American<br />

liver fluke Fascioloides magna was recorded in free-living red deer and roe deer in the wetlands of the<br />

Danube, east of Vienna since 2000. The aim of this study was to determine the current infection rate<br />

of the intermediate snail host Galba truncatula with F. magna and other digenetic trematodes in the<br />

area. A monitoring of G. truncatula from three locations near Orth/Danube was conducted during<br />

2008. Single collections were taken from three locations from the opposed southern Danube banks<br />

(=other locations). A total of <strong>3.</strong>871 G. truncatula were collected, measured and examined under the<br />

microscope for the presence of digenetic trematodes. Every tenth microscopically parasite-free snail<br />

was chosen as a random sample. Altogether 68 random samples and 30 microscopically detected<br />

isolated trematode stages were tested molecular biologically by PCR and sequencing. Two primer<br />

pairs were developed to enable both the detection of trematodes in general and the specific detection<br />

of F. magna in G. truncatula. In addition, a specific primer pair was chosen from literature for the<br />

detection of the common liver fluke F. hepatica, which is also a pathogen of humans.<br />

Overall, 96 trematode infections (prevalence 2,48%) were detected in the <strong>3.</strong>871 examined G.<br />

truncatula. Trematodes of Paramphistomoidea (prevalence 1,91%), Echinostomatoidea (0,46%)<br />

Strigeida (0,10%) and Plagiorchiida (0,05%) were found besides Fascioloidea. F. magna was found<br />

with an overall prevalence of 0,26% (n = <strong>3.</strong>871), whereby the highest prevalence was found at the<br />

southern locations (0,47%, n = 427), but also at two northern locations (0,20%, n = 1.975 and 0,30%,<br />

n = 1.347. The common liver fluke F. hepatica, was found once in a snail collected at Orth. The<br />

infection peak of F. magna was in July (1,15%).<br />

The comparison of microscopic and molecular biologic methods confirmed former studies, in which<br />

DNA-based methods have shown a higher sensitivity. It was possible to differentiate morphological<br />

similar trematode species by molecular genetic methods.<br />

Phylogeography of the East-Alpine members of the landsnail<br />

species Orcula dolium (Gastropoda: Pulmonata: Orculidae)<br />

Harl, J., Kruckenhauser, L., Sattmann, H., Duda, M. & Haring, E.<br />

Orcula dolium has the widest distribution among the species of the genus Orcula and inhabits the<br />

calcareous parts of the Alps and the Northern Carpathians. Since it had been described in 1801 by<br />

DRAPARNAUD, various authors added a minimum of 23 further subspecies. Most of these subspecies<br />

represent local forms that inhabit only small, partly isolated regions and differ from the nominate<br />

subspecies in their shell shape and the expression of their aperture's folds. Besides the common O.<br />

dolium dolium, six subspecies have been described from the Eastern Alps.<br />

Two of them, O. dolium edita and O. dolium raxae, are restricted to different elevations of high<br />

mountain areas. According to the literature, the nominate subspecies is sporadically found in the same<br />

habitats as the high alpine forms, but no intermediate morphs have been detected. This observation<br />

raises the question if these taxa represent distinct species. To determine whether these taxa are<br />

differentiated genetically and to reveal their relationships, snails were collected from sites covering the<br />

main part of the East Alpine distribution range of the species. Two mitochondrial genes (COI and 16S<br />

rRNA) as well as the nuclear histone H3-H4-spacer region were sequenced and genetic distances<br />

calculated. Additionally, morphometric landmark analyses were conducted to examine if the phylogeny<br />

is in accordance with shell morphological differentiation.<br />

In the trees based on mitochondrial data several highly distinct clades were found, which are mostly<br />

not congruent with the described taxa. In particular, the high Alpine subspecies do not represent<br />

distinct lineages. In the H3-H4-spacer region almost no variation was found within the O. dolium group<br />

and the tree does not reflect the mitochondrial haplogroups.<br />

The geological evidence for the phylogeny of sessile barnacles comes predominately from intertidal<br />

and shallow sublittoral records. Therefore, numerous balanoid species of genera such as Acasta,<br />

Concavus, Perforatus and Balanus are described. This wealth in data is contrasted by an extremely<br />

poor knowledge of open marine taxa which obligatorily cling to free swimming objects such as gars,<br />

cetaceans, sirenians, turtles and even sea snakes . This group is mainly represented by members of<br />

the coronuloid barnacles (chelonibiids, platylepadids & coronulids). The origin of the mainly sea-turtle<br />

fouling balanomorph family Chelonibiidae is still poorly documented. Aside from an erratic Eocene<br />

occurrence, assigned to an extinct subfamily, the extant subfamily Chelonobiinae did not appear in the<br />

fossil record before the Late Miocene. Now, a new lineage is recorded as an extinct sister-group of the<br />

Chelonibiinae. It is based on a 21-million-year-old fossil colony from Pucking (Ebelsberg Formation;<br />

Upper <strong>Austria</strong>). The new subfamily is known so far only from the proto-Mediterranean and the<br />

Paratethys seas and ranged from Early Miocene to Late Pliocene times. Members of the subfamily are<br />

characterised by large walls with tripartite rostra which display distinct sutures on the external surface.<br />

The tripartite rostrum, however, has evolved independently several times in the evolution of the<br />

balanomorphs and cannot be treated as synapomorphy. The subfamily comprises one new genus and<br />

two species.<br />

The sculpture of the host substratum is preserved as imprints along the carino laterals of one<br />

specimen. Although the pattern of ridges and furrows cannot be identified with certainty, the<br />

similarities with the sculpture of the carapax of modern Caretta suggests the new genus as earliest<br />

record of sea-turtle fouling in balanids. The co-existence of members of both subfamilies during the<br />

Miocene and Pliocene documents a higher diversity of chelonibiids in pre-Pleistocene times and<br />

indicates that Chelonibiinae were able to outcompete their supposed sister-group with the onset of the<br />

glacial cycles.<br />

The genus Mycobacterium including more than 100 described species is divided into three subgroups:<br />

the M. tuberculosis complex, M. leprae and NTM – non-tuberculosis mycobacteria. The latter have<br />

been isolated from hospitals, water, humid rooms, soil and from the mucosa of humans and animals.<br />

NTM can provoke potentially lethal lung infections in children or immunocompromised persons.<br />

Legionella spp. an anaerobic, gram-negative, rod-shaped, non-spore forming bacterium is the<br />

causative agent of legionellosis (Legionnaires´ disease). Legionellosis, which represents 4% of<br />

community-acquired pneumonia cases worldwide, can have a lethal outcome in 18-20% of cases if<br />

untreated. Legionella spp. has been isolated from air condition units, swimming pools, ground- and<br />

surface water. Legionnaires´ disease is acquired by the inhalation of infectious aerosols.<br />

Acanthamoeba spp., single-celled eukaryotic organisms, can provoke severe infections, including<br />

Acanthamoeba keratitis, GAE (granulomatous amoebic encephalitis) and infections of the lung and the<br />

skin. Acanthamoebae have two life cycle stages – a trophozoite and a cyst – and play a significant<br />

role as vectors for bacteria (particularly also Legionella spp. and MOTT).<br />

The aim of the present study is the establishment of a reference database for protein mass spectra of<br />

Legionella spp., NTM and Acanthamoeba spp. using MALDI TOF MS (Matrix Assisted Laser<br />

Desorption Ionisation Time of Flight Mass Spectrometry) and the MALDI Biotyper software. This<br />

reference database is aimed to serve as an essential tool for the identification of Legionella spp., NTM<br />

and Acanthamoeba spp. and furthermore for the detection of Legionella spp. and NTM in<br />

Acanthamoeba spp.<br />

There is a long-standing controversial about how parthenogenetic species can be defined in absence<br />

of a generally accepted species concept for this reproductive mode. An integrative approach was<br />

suggested, combining molecular and morphological data to identify distinct entities, and propose them<br />

as distinct taxa. Using this approach, speciation of parthenogenetic lineages was recently<br />

demonstrated for groups of bdelloid rotifers and oribatid mites. We investigated <strong>Austria</strong>n populations<br />

of the parthenogenetic oribatid mite Trhypochthonius tectorum. Besides morphological and molecular<br />

data, we included the chemical composition of complex exocrine gland secretions in our analyses.<br />

This is the first attempt to combine these three types of data for a delineation of parthenogenetic<br />

oribatid mites.<br />

We show that <strong>Austria</strong>n T. tectorum underwent a parthenogenetic radiation and now consists of three<br />

distinct lineages, each separated by morphology including morphometry, gland secretion profiles and<br />

mitochondrial cox1 sequences. This diversification happened in the last ten million years.<br />

Lake systems are fast responding to environmental changes, which makes their detection in the<br />

geological record challenging. However, fine sediments from lakes provide ideal preconditions to<br />

analyse different environmental proxy data in high resolution sampling method including pollen as in<br />

indicator for terrestrial adaptation.<br />

To demonstrate such high frequent vegetation changes far back in the Late Miocene (Pannonian, 11.4<br />

Ma), a continuous 98-cm core from the locality Mataschen in the Styrian Basin was studied each<br />

centimeter corresponding to approximately a decade in time. The vegetation at the beginning of the<br />

sequence was mainly characterized by a far distributed brackish marsh around Lake Pannon merging<br />

into forested swampy Taxidoideae wetlands. A moderate drop of the mean annual precipitation<br />

caused a change in the structure of the marsh as the formally dominating Poaceae were replaced by<br />

the more dry adapted Cyperaceae grasses within a few decades.<br />

The subsequent increase in annual rainfall is reflected by a rise of the lake level with a lag of 5<br />

decades. This led to an almost complete dieback of the marsh vegetation due drowning, but coincides<br />

with the expansion of the open-water dinoflagellate cyst Impaginium sp. As soon as the rainfall<br />

switched back to moderate levels of ~1100–1200 mm/yr, the rise of the lake level slowed down, the<br />

marsh plants could keep up again and the former vegetation belts became re-established. During the<br />

whole period of less than 1400 years, the other climatic parameters did not vary much, resulting in a<br />

constant composition of the zonal hinterland forests.<br />

For the first time, high-frequency interactions between climate and plants can be documented on a<br />

decadal scale in Late Miocene.<br />

Cichlids are an excellent model to study explosive speciation and adaptive radiation. Their<br />

evolutionary success has been attributed to their ability to undergo rapid morphological changes<br />

related to diet, and their particular breeding biology. Relatively minor changes in morphology allow for<br />

exploitation of novel food resources. The importance of phenotypic plasticity and genetically based<br />

differences for diversification was long recognized, but their relationship and relative magnitude<br />

remained unclear. We compared morphology of individuals of four wild populations of the Lake<br />

Tanganyika cichlid Tropheus moorii with their pond raised F1 offspring. The magnitude of<br />

morphological change via phenotypic plasticity between wild and pond-bred F1-fish exceeds pairwise<br />

population differences by a factor of <strong>2.</strong>4 (mean Mahalanobis distances).<br />

The genetic and environmental effects responsible for among population differentiation in the wild<br />

could still be recognized in the pond-bred F1-fish. All four pond populations showed the same trends<br />

in morphological change, mainly in mouth orientation, size and orientation of fins and thickness of the<br />

caudal peduncle. As between population differentiation was lower in the wild than differentiation<br />

between pond-raised versus wild fish, we suggest the narrow ecological niche and intense<br />

interspecific competition in rock habitats is responsible for consistent shape-similarity, even among<br />

long-term isolated populations.<br />

Increase of the corallum in the Silurian rugose coral Idiophyllum<br />

(Arachnophyllidae) from the Ningqiang Formation, China<br />

Rugose corals are a fossil marine group which appeared in the middle Ordovician and became extinct<br />

end of Permian. Rugosa are identified based on the morphological features of their skeletal elements<br />

such as septa, tabulae, dissepiments, and wall, which are observed from serial transverse and<br />

longitudinal thin sections. The Silurian rugose coral Idiophyllum Cao occurs in the Ningqiang<br />

Formation (Upper Llandovery), Ningqiang-Guangyuan area near the border of Shaanxi and Sichuan,<br />

China. This coral occurs as both compound and solitary forms. Its corallum is characterized by<br />

possessing carinate septa displaying pinnate arrangement, convex tabularium which consists of<br />

incomplete tabulae, wide dissepimentarium, and distinct cardinal fossula. Idiophyllum has major, minor<br />

and tertiary septa. Tertiary septa are inserted irregularly and partly. The total number of septa in this<br />

coral reaches up to more than two hundred. Seven species have been assigned to Idiophyllum (He<br />

and Chen, 1986; Kido and Sugiyama, 2005); Idiophyllum dabashanense, I. multifurcatum, I.<br />

ningqiangense, I, tenuiseptatum, I. major, I. shaanxiense and I. massulatum. One of them, I.<br />

massulatum has a compound thamnasterioid corallum. He and Chen (1986) indicated that in the<br />

compound corallum of I. massulatum generally 2 to 5 offsets arise in the axial or peripheral region of<br />

the corallum of the parent. Lin et al. (1995) mentioned that the increase in the solitary corallum of<br />

Idiophyllum is parricidal. However, characteristics of the increase in corallum of Idiophyllum and septal<br />

insertion which is observed in the offsets have not been described in detail. Additional specimens of<br />

Idiophyllum massulatum and the species of Idiophyllum with solitary form were collected in the<br />

Ningqiang Formation of Yanzishi, Guangyuan, Sichuan. In these species peripheral and parricidal<br />

increase were observed, respectively. Modes of increase in Idiophyllum, together with the septal<br />

insertion observed in the offsets, are presented.<br />

The eastern wolf: truths and myths – a molecular perspective<br />

There has been an extensive debate on origin and taxonomic status of wolf-like canids in the North<br />

American Great Lakes region and the consequences for conservation politics regarding these<br />

enigmatic predators. Many different hypothesis have been put forward, but in recent years the<br />

hypothesis that the eastern wolf represents a distinct species Canis lycaon that evolved in North<br />

America as sister species of the coyote C. latrans and not a sub-species of the old world evolved gray<br />

wolf C. lupus received an increasing number of followers despite questionable evidence for this<br />

particular hypothesis, which largely rests on the presence of exclusively coyote-like mtDNA in (present<br />

and historic) samples from the Great Lakes region.<br />

Many recent studies have focused on elucidating the evolutionary history of this enigmatic canid<br />

taxon, but have used a restricted geographic and taxonomic sampling and/or applied insufficient<br />

amount of molecular markers. Using a broad geographic and taxonomic sampling (including historic<br />

samples) and applying maternally, paternally and biparentally inherited molecular markers, we<br />

demonstrate that the wolves of the Great Lakes regions do not represent a native North American wolf<br />

species but rather are a population of gray wolves that has repeatedly experienced introgression from<br />

the coyote. Increased genetic drift as a consequence of reduced population size during Pleistocene<br />

glaciations likely resulted in fixation of coyote-like haplotypes in this geographic region.<br />

Thus, we demonstrate that both broad taxonomic and geographic sampling and large amounts of<br />

molecular markers with different modes of inheritance are required to elucidate the complex<br />

evolutionary history and hybridization dynamics of North American wolf-like canids.<br />

erscheinen lassen. Die Zahl der Lehrstühle und Professuren wurde verringert, immer weniger<br />

Studierende wurden umfassend ausgebildet. Jetzt aber fehlen weltweit Expertinnen und Experten mit<br />

fundierter Artenkenntnis an Universitäten, naturkundlichen Museen, Schulen, in der Feldforschung<br />

und in der Naturschutzpraxis. So auch in Österreich.<br />

Die Erhaltung der biologischen Vielfalt setzt aber fundierte Artenkenntnis voraus. Top ausgebildete<br />

Fachleute der Taxonomie und Systematik sind also unerlässlich, damit Österreich auch weiterhin<br />

seinen internationalen Verpflichtungen zur Erhaltung der biologischen Vielfalt nachkommen kann.<br />

Das österreichische MAB-Nationalkomitee fordert daher gemeinsam mit zahlreichen<br />

WissenschaftlerInnen und Institutionen, dass der Ausbildung in Taxonomie und Systematik an den<br />

Universitäten und den naturkundlichen Museen höchste Priorität eingeräumt und darüber hinaus die<br />

beruflichen Perspektiven junger TaxonomInnen verbessert werden.<br />

The aim of the World Register of Marine Species (WoRMS) is to provide an authoritative and<br />

comprehensive list of names of marine organisms, including information on their synonymy. While<br />

highest priority goes to valid names, other combinations in use are included to facilitate linking data<br />

from various sources, both online and offline. Echinoids (sea urchins) are covered by the World<br />

Echinoid Database (part of WoRMS). Taxonomic coverage of the database includes all currently<br />

known extant echinoid genera and species, as well as most of the valid fossil echinoid genera. Extinct<br />

species, which surpass modern echinoid diversity by a factor of 10, are at present included only when<br />

they have erroneously been reported from modern faunas or are type species of extant genera.<br />

The information contained in the World Echinoidea Database (WED) derives largely from Mortensen’s<br />

epochal Monograph of the Echinoidea (1928-1951), updated by the data contained in the Index of<br />

Living and Fossil Echinoids by Kier & Lawson (1978) covering the years 1925-70 and Kroh (<strong>2010</strong>)<br />

covering the years 1971-2008. Information on distribution, ecology, and physiology are still largely<br />

missing from database, but are included progressively as the database is complemented with data<br />

from additional, detailed studies. The classification used in the WoRMS and the World Echinoid<br />

Database is that of Kroh & Smith (<strong>2010</strong>).<br />

With about 1,070 valid extant echinoid species known from the world oceans, sea urchins constitute a<br />

relatively small group compared to other echinoderms. Only extant crinoids are less diverse than<br />

echinoids. However, in the fossil record things look different, with echinoids and crinoids dominating<br />

while asteroids, ophiuroids, and holothuroids are less diverse. This shift in diversity patterns is due to<br />

differing lifestyles, skeletal construction, and concomitant biostratinomic and taphonomic pathways.<br />

The diversity of fossil Echinoidea vastly surpasses present sea urchin biodiversity. More than 10,000<br />

nominal species and 1,000 genera have been described. Although large numbers of these turn out to<br />

be junior synonyms, new species continue to be discovered.<br />

Recently, a large number of Philippine upper shelf sea urchins (Echinodermata: Echinoidea) became<br />

available, presumably due to shifting of local fishing activity from over-exploited shallow water habitats<br />

to deeper areas. The use of tangle nets and bottom fishing accounts for a huge number of by-catch,<br />

including echinoids. The faunal spectrum recovered from these fishing nets is rather selective,<br />

consisting mainly of large and epifaunal species, while burrowing or small species are<br />

underrepresented. Among the echinoids recovered, members of the genus Plesiozonus (Irregularia:<br />

Spatangoida) are especially large, often exceeding 120 mm test length and are thus commonly<br />

collected by the fishermen. Previously, Plesiozonus species were known by very few specimens only.<br />

Consequently, little is known on their biology, ecology, and physiology. While cleaning specimens of<br />

Plesiozonus hirsutus, we discovered double-valved bivalves in their rectum. Our first assumption,<br />

namely that these animals were simply swallowed by the deposit-feeding sea urchins proved to be<br />

unlikely: in every specimen with preserved intestine, a single articulated bivalve was located close to<br />

the periproct and contained mummified tissue. This strongly suggested that the bivalves were actually<br />

living inside the intestine of the sea urchins, rather than having been accidentally swallowed during<br />

feeding. Considering the size of the bivalves, which approaches or exceeds that of the respective<br />

echinoid peristome, the latter possibility seems even less likely. The bivalves are characterized by an<br />

extremely thin shell as well as a reduced hinge region and represent yet unknown galeomatid or<br />

montacutid species. Both taxa are known to live in association with echinoderm hosts, mainly<br />

holothurians. From sea cucumbers, the minute endoparasite Entovalva mirabilis has been reported. In<br />

echinoids, endoparasitic bivalves have not yet been described, although three galeomatid species are<br />

known to live externally attached to the periproct of the spatangoid Brissus latecarinatus. We<br />

hypothesize that it is probably only a small evolutionary step from such a life style to an endoparasitic<br />

one. Especially so, as Entovalva has been observed to actively force its way back into the intestine of<br />

its holothurian host when artificially removed.<br />

Population genetics and phylogeography of Cylindrus obtusus<br />

(Gastropoda: Pulmonata: Helicidae) an endemic of the <strong>Austria</strong>n<br />

Alps<br />

Kruckenhauser, L., Haring E., Däubl, B. Cadahia, L., Zopp, L. & Sattmann, H.<br />

Museum of Natural History Vienna, Burgring 7, A-1010 Vienna, <strong>Austria</strong><br />

E-mail: luise.kruckenhauser@nhm-wien.ac.at<br />

Cylindrus obtusus (Helicidae) is a hermaphroditic land snail, endemic in the <strong>Austria</strong>n Alps, which is<br />

restricted to high elevations (1600 to 2500 m asl) and limestone. As a specialist of high alpine rocky<br />

habitats, C. obtusus has a quite patchy distribution area which may become even further reduced in<br />

the future due to global warming. Previous investigations revealed geographic differences in the<br />

genital apparatus: All specimens from the more western populations had one stylophore and two<br />

equally developed mucus glands more than twice the length of the stylophore. In contrast, in<br />

individuals from the eastern margin of the species distribution one or two mucus glands were found<br />

and the size ratio between stylophore and mucus gland(s) was highly variable. To find out whether<br />

these anatomical differences reflect a genetic differentiation, which might be an indication for distinct<br />

glacial refugia, we investigated a 650 bp fragment of the COI sequence (200 individuals) and 9<br />

microsatellite loci (500 individuals from 29 populations) from samples covering the whole distribution<br />

range of the species. The COI sequences showed a geographic differentiation between eastern,<br />

central and western populations. However, genetic distances are small (max. 1.7 %). The<br />

microsatellite analysis reveals a high differentiation between the populations implying restriction of<br />

gene flow. The highest genetic variability was found in the central populations. Remarkable nearly all<br />

individuals from the eastern populations, which are variable in their genital morphology, are<br />

homozygous in all microsatellite loci (although different alleles were found within populations). The<br />

most plausible explanation for this finding is an altered mode of reproduction. Further investigations<br />

shall elucidate whether this lack of heterozygotes is caused by selfing and if so, why it occurs at such<br />

a high frequency.<br />

Genetic variation in brown trout Salmo trutta across the<br />

Danube, Rhine, and Elbe headwaters: a failure of the<br />

phylogeographic paradigm?<br />

Population genetic screening (N = 97) of brown trout Salmo trutta across the Danube/Rhine/Elbe<br />

catchments of <strong>Austria</strong> and Bavaria revealed a counter-intuitive phylogeographic structure with near<br />

fixation of the Atlantic lineage in the Bavarian Danube. Along the <strong>Austria</strong>n Danube, phylogeographic<br />

markers (mtDNA and LDH-C1) revealed increasing percentages of Danube-specific alleles with<br />

downstream distance. Pure Danube lineage populations in <strong>Austria</strong> were rare, occurring as isolate<br />

relicts either within or on the edge of previously glaciated regions north, south, and east of the Alps,<br />

whereby unglaciated regions revealed high percentages of Atlantic lineage genotpyes. Both empirical<br />

data and simulated hybrid comparisons support that trout in non-glaciated regions of <strong>Austria</strong> have an<br />

admixed origin largely based on natural colonization from Atlantic basin watersheds. In contrast, most<br />

trout populations in glaciated regions of <strong>Austria</strong> south of the Alps revealed admixture based primarily<br />

on human-mediated release of hatchery strains. Despite the extensive use of Atlantic lineage hatchery<br />

strains in management, little evidence of first generation stocked fish or F1 hybrids between stocked<br />

and wild fish was found.<br />

The distribution pattern of the Atlantic and Danube lineages, as well as the clear signal of natural<br />

admixture is difficult to explain without invoking strong biological mechanisms in combination with a<br />

not-yet-visualized complex paleo-hydrological scenario. We conclude that the Atlantic lineage of<br />

brown trout is native to regions of the upper Danube and has been a very successful invader into<br />

unglaciated regions of the <strong>Austria</strong>n Danube north and east of the Alps, but there is no sign of its<br />

natural occurrence on the previously glaciated south slopes of the Alps.<br />

Digenean trematodes are a large group of internal metazoan parasites that are characterized by a<br />

complex life cycle including mollusc and vertebrate hosts. This study focuses on trematodes of the red<br />

deer (Cervus elaphus) in the Danube backwater forests southeast of Vienna. Particular emphasis was<br />

given to the naturally occurring liver fluke Fasciola hepatica and the introduced American liver fluke<br />

Fascioloides magna and the species specific differentiation between these two species. The former is<br />

a pathogen of medical and veterinarian, the latter only of veterinarian relevance.<br />

Between May and November 2008, a F. magna-monitoring within the area of the “Nationalpark<br />

Donau-Auen” has been performed. Altogether, 158 deer faeces samples were collected from 13 sites.<br />

All samples were processed for microscopy with a modified Benedek sedimentation method and<br />

subsequently screened for trematode eggs. A collection of samples was chosen for molecular biology.<br />

109 samples were homogenized, the DNA was extracted by two different types of DNA-extraction kits<br />

and subjected to three different kinds of PCR (trematodes, F. magna, F. hepatica). Species-specific<br />

differentiation was achieved by sequencing. In 49 of 158 samples (31%) trematode eggs were found<br />

by microscopical means. Additionally, there were eggs found in six samples which could not be<br />

specified. With molecular methods, 35 of 109 samples (32%) showed positive results during PCRs.<br />

The most frequent trematode species were members of the family Fasciolidae (29 samples), followed<br />

by Paramphistomidae (eleven samples). One sample contained eggs of Dicrocoeliidae and eleven<br />

samples showed eggs/DNA of more than one trematode species.<br />

The overall trematode burden in the investigated area was 37%. This was not surprising concerning a<br />

naturally parasite load of wild living ruminants. However, the remarkably high percentage of positive F.<br />

magna samples points out the dangerous potential of an introduced parasite. No one sample was<br />

positive with F. hepatica.<br />

The Azores is an archipelago composed of nine volcanic islands, located almost midway between the<br />

North American and European continents. In this relatively young island system, fossiliferous deposits<br />

are only found on the oldest island, Santa Maria. These strata are mainly Late Miocene to Early<br />

Pliocene in age. A second set of outcrops is associated with Pleistocene wave-cut platforms and<br />

presumably of Eemian age (Pleistocene). These deposits are relatively small, outcropping mostly in<br />

the coastal areas, and consist of lithic sandstones and carbonates intercalated by volcanic material,<br />

testifying periods of relative calm between intensive volcanic activity, during the formation of the<br />

island. During the international workshops ‘Palaeontology in the Atlantic islands’ (2002, 2006–2009),<br />

new echinoid material was collected, mainly composed of disarticulated fragmented skeletal material.<br />

The echinoid fauna found in the Mio-Pliocene outcrops of Santa Maria island, is dominated by tropical<br />

shallow waters taxa (Eucidaris tribuloides, Echinoneus cf. cyclostomus, Clypeaster altus, Meoma ?<br />

sp.), all locally disappeared with the exception of the temperate species Echinocyamus pusillus.<br />

Additionally, remains of two undetermined species of Echinocardium were also found. The Pleistocene<br />

material, in contrast, represents a fauna more typical of temperate waters: Arbacia lixula,<br />

Paracentrotus lividus and Sphaerechinus granularis. All three species are common present day<br />

inhabitants of Azorean rocky shores. In spite of the facies restriction and thus the palaeoenvironments<br />

preserved, it is clear that the fossiliferous deposits of the Santa Maria can aid in the understanding of<br />

how the fauna in this oceanic island system was shaped through time.<br />

The lichen mycota of Armenia has been poorly studied to date, especially when compared to the<br />

mycota of the other Caucasian countries Georgia and Azerbaijan. Only very few studies have been<br />

undertaken by Armenians like V. Nikogosyan in the Sixties and A. Abrahamyan in the Eighties but Sh.<br />

Barchalow from Azerbaijan has mentioned 195 species from Armenia in a series of papers dedicated<br />

to the Caucasus region in the Sixties of last century. The Czech lichenologist A. Vězda has visited the<br />

country and distributed some species in his famous exsiccate. The Czech naturalist V. Vašak and the<br />

Viennese botanist E. Vitek have collected specimens and deposited in the lichen herbaria GZU (Graz)<br />

and W (Vienna). In order to obtain more representative data about the lichen biodiversity a large range<br />

of habitats from low to high elevations and from dry to humid sites have been sampled. More than 900<br />

specimens have been collected in 2005 and 2006 containing 246 taxa, of which 114 have been new<br />

for Armenia (Harutyunyan & Mayrhofer 2009). In addition a phylogenetic study of black fungi inhabiting<br />

lichens from seasonally arid habitats in Armenia has been carried out (Harutyunyan et al. 2009).<br />

Based on a comprehensive evaluation of the literature (more than 50 publications), herbarium and<br />

field studies, Armenia has an actually known diversity of c. 400 species. Crustose saxicolous taxa<br />

dominate, which is in accordance with the dry climate and mountainous nature of the country.<br />

A catalogue is in preparation which includes information regarding references, localities placed under<br />

provinces, ecology and herbarium specimens as a solid basis for further inventories or taxonomic<br />

projects in this country.<br />

Systematics and cryptic species in lichenized fungi<br />

In lichen systematics the naming of species results from their accurate delimitation based on<br />

morphological and, increasingly, on phylogenetic data. During the last years several studies have<br />

presented multilocus phylogenetic analyses that elucidated the identity of many sterile lichen species,<br />

or conclusively placed morphologically well known taxa to well defined phylogenetic groups. The<br />

microfilamentous lichens Cystocoleus ebeneus and Racodium rupestre were confirmed to be<br />

ascomycetes belonging to the Dothideomycetidae but not close to lichenized members within the<br />

subclass. Similarly, the genus Normandina turned out to be a monophyletic group within the<br />

Verrucariaceae. Morphological and phylogenetic species concepts complement each other. In-depth<br />

molecular studies focusing on critical lichen groups often reveal the presence of cryptic species<br />

forming well defined phylogenetic clades and result in the description of new taxa. However, the<br />

phylogenetic species concept should also be carefully considered when applied to cosmopolitan<br />

lichens which exhibit a high degree of morphological diversity, such as species constituting the<br />

Tephromela atra complex. In such cases what might appear to be clear genetic differentiation at a<br />

small scale may dissolve when the sampling is extended to wider geographic areas, owing to ongoing<br />

genetic differentiation and/or incomplete lineage sorting.<br />

Species evolution in lichen symbiosis: Tephromela atra species-<br />

complex as a model study<br />

Lichens constitute one of the most wide-spread fungal symbioses. However, the contribution of<br />

symbiotic relationships to species diversification is still under-investigated among this group of fungi.<br />

Lichenized fungi (mycobionts) depend on their association with an algal partner to form the symbiotic<br />

structure. These fungi are found only in the lichenized stage, and therefore represent interesting<br />

models to address questions of evolution under symbiotic conditions. The classification of lichens<br />

relies largely on morphology, but many species are heterogeneous and represent unresolved species<br />

complexes. In these cases the morphological classification fails to resolve species complexes and<br />

identify uniform species. Furthermore, species complexes prevent the understanding to what extent<br />

mycobiont genotypes correlate with photobiont selectivity. We investigate the genetic aspects of the<br />

symbiotic speciation of lichens using taxa belonging to the cosmopolitan Tephromela atra species<br />

complex as models. Tephromela atra has been considered as a phenotypically and ecologically<br />

plastic, cosmopolitan species occurring on diverse substrata. It is an example par excellence for a<br />

lichen species complex in Europe with taxa that were controversially considered as varieties or<br />

species. Further, the association of Tephromela atra with different photobiont species could indicate a<br />

certain degree of selectivity or specificity for the algal partners in diverse habitats, and can play a<br />

determinant role in speciation processes.<br />

The fungus Schizoxylon albescens occurs both as lichen and as saprobe. Lichenized colonies grow<br />

on bark of Populus tremula, saprotrophic morphs grow on dead Populus branches. We wanted to (i)<br />

test if lichenized and saprotrophic Schizoxylon albescens are genetically distinct, (ii) investigate<br />

photobiont association and diversity, (iii) investigate interactions between fungi and algae that occur<br />

during co-cultivation, (iiii) test if Schizoxylon shows algal selectivity during the lichenization. Fungal<br />

and algal genetic diversity were investigated for three markers. Algae from lichenized thalli were<br />

isolated in axenic cultures, and the isolate sequence diversity was compared with the algae amplified<br />

directly from thallus fragments. Co-culture experiments of fungi and algae were performed to study<br />

morphological interaction patterns. Two distinct phylogenetic units are revealed in S. albescens, which<br />

are interpreted as phenotypically cryptic species.<br />

The algae are related to Coccomyxa and Pseudococcomyxa, and form two distinct sister-clades<br />

separating samples isolated in cultures from those amplified directly from thallus fragments, indicating<br />

that more easily cultured strains of algae are not necessarily major components of the lichens.<br />

Schizoxylon albescens interacts with isolated algal strains, similarly to fungal-Coccomyxa-symbioses<br />

in nature. As the system is maintained without difficulty in culture, it can potentially be an easily<br />

controlled lichen symbiosis study system under lab conditions.<br />

The present investigation deals with the mollusk evolutionary patterns and environmental change in a<br />

lower Middle Miocene succession in the Sinj Basin (Dalmatia, SE Croatia) reflecting the depositional<br />

history of a long-lived freshwater lake. Despite its mature investigation stage, an analysis of a<br />

quantified mollusk record, providing insight into species contributions, taxonomic relationships and the<br />

nature of the morphologic changes, is completely missing up to now.<br />

The taxonomic diversification of freshwater gastropods and its connection with morphologic disparity<br />

events are documented for a ca. 100-m-thick section representing the topmost infill of the Sinj Basin.<br />

Based on the available age model, these alterations occur extremely fast on a millennial scale, re-<br />

proving the significance of long-lived lakes for evolutionary research. Furthermore, the simultaneity of<br />

morphologic shifts in systematically independent taxa suggests them to be tightly linked to<br />

environmental changes. Most probably, climatic fluctuations leading to variations in lake-level and<br />

habitat types are the driving factors for these radiation events.<br />

The study provides statistical treatment of quantified samples accompanied by a taxonomic revision of<br />

the taxa. Additionally, based on the mollusk distribution a paleoenvironmental interpretation is given,<br />

supported by sedimentological data and previous palynological analysis. Actually, it supports previous<br />

results of the section’s division into two limestone-coal cycles, grading from shallow intermediate-<br />

energy settings with high freshwater input via fossil-poor transgressive limestones to shallow low-<br />

energy conditions, resulting finally in a total lake drought at the section top.<br />

The discussion will focus on the evolutionary lines of four species, two of Melanopsis and two of<br />

Prososthenia. All four species appear almost continuously and can be divided into several<br />

morphotypes based on different sculpture features; in some cases also size plays a role. It will be<br />

demonstrated that the morphs occur sequentially, each more or less limited to a special interval.<br />

Moreover, the changes in morphology appear at the same time in different taxa.<br />

Biology and phylogeny of the Ophrys tenthredinifera species<br />

group in Crete<br />

Rakosy, D. & Paulus, H.F.<br />

The species of the genus Ophrys rely on sexual deception for pollinator attraction, imitating the<br />

complex olfactory, visual and tactile cues of their pollinator’s females in order to attract males. This<br />

plant – pollinator relationship is highly specific, allowing for strong prezygotic isolation of Ophrys<br />

species, coupled with comparatively week postzygotic isolation mechanisms. The occurrence of<br />

hybrids and the high morphological variability of most species, have led to a confusing classification<br />

system of the genus. This is also the case of the newly described species complex Ophrys<br />

tenthredinifera. Till recently there was only one species (Op. villosa DESFONTAINES 1807) or<br />

subspecies (Op. tenthredinifera subsp. villosa WILLDENOW 1805) described from the eastern Medi-<br />

terranean basin. Delforge (2005) describes, based mainly on phenological and morphological criteria,<br />

3 new species for the region: Op. Ulyssea (Ionian Islands), Op. leochroma (Egean Islands) and Op.<br />

dyctinnae (Crete). A fourth new species Op. dimidiata has been recently descoverd in Crete. Due to<br />

the absence of evident morphological differences, because of high interspecific variability the<br />

taxonomic status of these taxa has been questioned.<br />

The present study employs genetic fingerprinting, biotests and morphometry to investigate the<br />

strength of prezygotic reproductive isolation (based on pollinator specificity) and genetic separateness<br />

of the four taxa occurring in Crete: Op. dyctinnae, Op. leochroma, Op. dimidiata and Op. villosa. Using<br />

classic morphometric analysis we attempt to identify reliable traits for species delimitation. At this<br />

moment only partial results are available, these being mainly the results from pollinator experiments<br />

and partial results from morphometrics. From the four occurring species, only three could be analyzed,<br />

as Op. villosa seems to be extremely rare in Crete. Pollinator experiments indicate that these three<br />

species are indeed reproductively isolated from each other, with only few cases where one Ophrys<br />

species attracted two different pollinators. Additionally, it became apparent that in several locations<br />

two or all three species occurred sympatrically. The molecular analysis will have to confirm the species<br />

delimitation drawn by pollinator experiments, thus certifying the species status of these taxa.<br />

Oil gland chemistry as a source of novel taxonomic characters<br />

in glandulate Oribatida (Acari)<br />

Raspotnig, G.<br />

Institute of Zoology, Karl-Franzens University Graz, Universitätsplatz 2, 8010 Graz, <strong>Austria</strong>,<br />

e-mail: guenther.raspotnig@uni-graz.at<br />

Oil glands (syn. opisthonotal glands) constitute the major exocrine system in oribatid and astigmatid<br />

mites. These glands are present in many different character states in more than 15.000 species.<br />

According to current ideas, oil glands evolved only once in ancient oribatids several hundred million<br />

years ago and represent an important synapomorphic character of the “glandulate” Oribatida (= the<br />

four more derivative cohorts of Oribatida [Parhyposomata, Mixonomata, Desmonomata, Brachypylina]<br />

and the Astigmata). Moreover, oil glands produce multicomponent secretions that have been proven<br />

valuable complex data for phylogenetic studies on different taxonomic levels. 1) With respect to<br />

oribatid gross taxonomy, major evolutionary traits are reflected by oil gland chemistry: The (primitive)<br />

Parhyposomata are characterized by phenols and naphthols while distinct sets of terpenes and<br />

aromatics (so-called “Astigmata-compounds”) are considered to have evolved stepwise within ancient<br />

mixonomatans, now characterizing all rectant taxa above middle-derivative Mixonomata (i.e., higher<br />

Mixonomata, Desmononata, Brachypylina and the Astigmata). In these terms, the evolutionary origin<br />

of Astigmata within Oribatida is strongly supported by chemical data. In some of the groups mentioned<br />

above, the “Astigmata-compounds” have again been reduced and replaced by novel components such<br />

as iridoid monoterpenes in some Euphthiracaroidea (Mixonomata) or by alkaloids in some groups of<br />

Brachypylina. 2) In addition, regarding oribatid alpha-taxonomy, species- or even population-specific<br />

secretion patterns have already successfully been applied to the delineation of phyletic lines within<br />

species complexes or even led to the discovery of cryptic species.<br />

In all, about 100 different oil gland secretion components have already been identified. Another 200 -<br />

so far unknown - components await their structural elucidation. I here summarize the importance of oil<br />

gland secretions profiles as independent character sets for modern integrative taxonomic studies in<br />

the Oribatida.<br />

Middle Miocene holothurians (Echinodermata) from the Vienna<br />

Basin (<strong>Austria</strong>)<br />

Compared to other modern echinoderm groups, the evolutionary history of holothurians is poorly<br />

understood, owing to their preservation almost exclusively as microfossils. In comparison to older<br />

strata, the Cenozoic fossil record of sea cucumbers is particularly scarce. This is in stark contrast to<br />

most other invertebrate groups, in which the fossil record tends to improve with declining age.<br />

The Central Paratethys (Europe) is one of the most intensely studied Neogene basins and has yielded<br />

a rich echinoderm fauna including representatives of all modern echinoderm classes. Unfortunately,<br />

most of the holothurian sclerites reported from that area by previous authors have been lost. Here we<br />

present new data based on a survey of old micropalaeontological samples (second half of the 19 th<br />

century), deposited in the Natural History Museum of Vienna, as well as new samples collected from<br />

deposits rich in echinoderm remains. The samples studied derive from silty clays and marls from the<br />

<strong>Austria</strong>n part of the Vienna Basin and are Badenian (= Langhian to Early Serravallian) in age. The<br />

samples were processed to preserve the fine fractions needed for the successful recovery of<br />

holothurian sclerites. Out of more than twenty-five samples, only two yielded well preserved<br />

holothurian echinoderms.<br />

At least ten biological species of the Molpadiida (Molpadiidae), Dendrochirotida, Aspidochirotida<br />

(Holothuriidae), Apodida (Synaptidae, Chiridotidae, and Myriotrochidae) could be documented in form<br />

of sclerites from the body wall, as well as calcareous ring elements. Especially the classic ‘Badener<br />

Tegel’-samples of Baden near Wien (former brickyards between Baden and Sooss) yielded<br />

exceptionally well-preserved material. Infaunal molpadiid representatives dominate the faunal<br />

holothurian association of the ‘Badener Tegel’. This includes the first fossil record of small amorphous<br />

ferric phosphatic dermal granules, which are typical for members of the Molpadiidae and a unique<br />

biomineralogical phenomenon for the Echinodermata as a whole.<br />

The endosymbiont Wolbachia in fruit flies of the genus<br />

Rhagoletis: Horizontal transfer and impact in speciation<br />

Schuler, H.<br />

Institute of Forest Entomology, Department of Forest and Soil Sciences, Boku, University of Natural<br />

Resources and Life Sciences, Vienna, <strong>Austria</strong><br />

Wolbachia is an endosymbiotic bacteria present in up to 65% of all insects. Wolbachia infections are<br />

described in all major insect orders. This bacterium manipulates the reproduction and causes male-<br />

killing, parthenogenesis, feminization and cytoplasmic incompatibility (CI). The most common effect is<br />

CI, an incompatibility between sperm and egg caused by crossing of infected males with uninfected<br />

females. This incompatibility can lead to a reduction of gene flow in a population and hence lead to<br />

reproductive isolation.<br />

The Apple Maggot R. pomonella has been the focus of sympatric speciation over more than a century.<br />

In the middle of the 19 th century a population shifted from the native host hawthorn to the newly<br />

introduced apple. These populations are ecologically and genetically different. Different Wolbachia-<br />

infections were found in the two host species and potential impact in speciation will be discussed.<br />

The Eastern Cherry Fruit Fly, R. cingulata, infests different Prunus species. Native to North America,<br />

this species was introduced to Europe in the 1980ies where it coexists with the European Cherry Fruit<br />

Fly Rhagoletis cerasi. R. cerasi, is an established field model species for multiple Wolbachia infections<br />

and CI. Two strains of R. cerasi were detected in R. cingulata and a potential horizontal Wolbachia<br />

transfer will be discussed.<br />

Miocene dinoflagellate cysts as links between taxonomy and oil<br />

industry<br />

<strong>Austria</strong><br />

At about 11.6 Ma a glacioeustatic sea-level drop caused the final disintegration of the Paratethys Sea,<br />

and Lake Pannon arose in the Pannonian basin system. The benthic ecosystem collapsed at that<br />

point and marine life completely vanished. The lake was initially brackish, slowly freshening and<br />

slightly alkaline. Lake Pannon attained a maximum length of 860 km (from the Karlovac Basin close to<br />

Zagreb in the west to the Transylvanian Basin in Romania in the east) and a width of 550 km (from the<br />

Vienna Basin in the north to Belgrade in the south). It covered an area of c. 290,000 km 2 . The lake<br />

was highly structured by numerous islands and mountain ranges. Its maximum water depth may have<br />

reached 800 m in its central part but less than 200 m elsewhere. The aberrant water chemistry and the<br />

decline of marine taxa gave rise to the evolution of an impressive assemblage of dinoflagellate cysts.<br />

Whilst the dinoflagellate cyst assemblages are fairly similar to assemblages recorded from adjacent<br />

areas during the Middle Miocene, the assemblage is nearly fully endemic thereafter in Lake Pannon.<br />

Simultaneously, the high diversity of 126 taxa declines strongly to about 40 taxa. The paleoecological<br />

interpretation of the dinoflagellate assemblages in Lake Pannon is complex. Most taxa have roots in<br />

marine ancestors, which became adapted to brackish water conditions of Lake Pannon with the onset<br />

of the Late Miocene. Therefore, a straightforward comparison with congeneric open marine taxa is<br />

difficult. A more promising source for comparison are the marine-derived assemblages from the Black<br />

Sea, the Marmara Sea, the Caspian Sea, the Aral Sea and some adjacent lakes.<br />

This endemism is reflected by the absence of cosmopolitan taxa and the appearance and dominance<br />

of new morphotypes. Well studied examples are Spiniferites bentorii and Impagidinium sphaericum<br />

and their allies. Both taxa exhibit, an enormous morphological variability within Lake Pannon. This<br />

variability has been used to introduce several endemic species/subspecies. These taxa are probably<br />

mere eco-morphotypes and are difficult to define as systematic units. Nevertheless, they are valuable<br />

tools for Pannonian stratigraphy. A typical application is their use in biostratigraphic correlations of well<br />

cores in the Pannonian Basin by oil companies. Thus, despite the problematic taxonomic status of<br />

many of these morphotypes, their applicability in industry is obvious.<br />

Clypeasteroid echinoids of the Indian Subcontinent<br />

Clypeasteroid echinoids are common members of shallow benthic habitats in late Eocene to modern<br />

echinoid faunas of the tropical and warm temperate zones. Due to their high fossilization potential,<br />

they have an exceptionally good fossil record and have been intensely studied in the past. From the<br />

Indian subcontinent, clypeasteroids have been recorded by Grant (1837), Duncan & Sladen (1882-86)<br />

and a number of subsequent authors. Many of these records, however, lack proper stratigraphical<br />

information and data on associated taxa.<br />

We are currently revising the clypeasteroid taxa documented from the Indian Subcontinent based on<br />

the type material housed at the Geological Survey of India, as well as new material collected from the<br />

field by one of us (DKS). Clypeasteroid diversity is low in the Eocene, rises in the Oligocene and<br />

reaches a peak in the Early Miocene of the Indian subcontinent. From the Early Miocene onwards,<br />

clypeasteroid and echinoid diversity as a whole drops to comparatively low levels in the Pliocene.<br />

Many of the taxa reported previously from the Eocene, actually derive from Oligocene deposits<br />

records. The genus Clypeaster, for example, does not occur in the Indian Eocene at all, despite<br />

several previous records stating the contrary. The Eocene deposits, so far, yielded only<br />

representatives of Echinocyamus and the enigmatic fibulariid Tridium. Clypeaster is the most diverse<br />

of the Indian clypeasteroid genera, being represented by almost 20 species in the Indian Cenozoic. In<br />

the Miocene a second group becomes important – the astriclypeids, with forms that share<br />

characteristics of the two astriclypeid genera Amphiope and Echinodiscus.<br />

Lichens are a species-rich group of symbiotic organisms found in every ecosystem on the planet.<br />

Relatively few areas of the globe have had the benefit of comprehensive lichen inventories and many<br />

species remain to be discovered. In a recent project in southeast Alaska (U.S.A.) we inventoried<br />

lichens and lichen-dwelling parasitic fungi in the 53 km 2 Klondike Gold Rush National Historic Park,<br />

largely without the benefit of a written flora and consolidated identification keys. We documented a<br />

total of 766 species, the largest ever found for a comparable study area in the New World (Spribille et<br />

al. <strong>2010</strong>). More remarkably, fully 10% of the documented species were either new to science or in a<br />

category we called ‘known unknowns’ – species with an identity but currently without a name, for a<br />

variety of reasons. Lichen inventory in poorly known regions is an exercise in observational feedback<br />

that requires an organic interaction with applied systematics and a deep knowledge of the global<br />

literature dataset. It is critical that the nuances of the systematic decision-making process are<br />

explained to conservationists and land managers with an eye to fully accounting for biodiversity and<br />

adequately protecting species of unresolved taxonomic status.<br />

What are conodonts?<br />

Suttner, T.J. 1<br />

1 <strong>Austria</strong>n Academy of Sciences (CPSA) c/o University of Graz - Institute for Earth Sciences (Geology<br />

& Paleontology), Heinrichstrasse 26, A-8010 Graz, e-mail: thomas.suttner@uni-graz.at<br />

Conodonts are a group of extinct marine organisms that are divided into Proto-, Para- and<br />

Euconodonta. Commonly fossil remains are represented by 0.5-4-mm sized discrete elements<br />

consisting of apatite. These elements were in use as biostratigraphic tool for Palaeozoic to low<br />

Mesozoic strata long before the first “conodont-animal” was discovered (Briggs et al., 1983). As soon<br />

as fused conodont clusters, bedding plane or natural assemblages were known, it became obvious<br />

that several element types (S, M and P elements) belong to distinctive apparatuses. Since its<br />

discovery by Pander in 1856 about 284 genera are described, which result in more than 3000 species.<br />

Until now the phylogeny of conodonts is still controversial.<br />

Szaniawski (2002) discussed the chemical composition and anatomical similarity of simple cone<br />

elements of protoconodonts in comparison with spines of the grasping apparatus of chaetognaths. On<br />

the basis of molecular investigations he concluded that chaetognaths should have originated at about<br />

the same time as protoconodonts, and that protoconodonts of the lineage of Phakelodus probably<br />

formed a stem group of chaetognaths. In contrast, Euconodonta are considered as early vertebrates<br />

probably being more derived than hagfish or lamprey (Donoghue and Purnell, 2005). This is based on<br />

about 13 natural assemblages of Euconodonta from Scotland, South Africa and Canada. Specimens<br />

are about 4-10-cm large, elongate, possessing a head with eyes, extrinsic eye muscles, a notochord,<br />

chevron-shaped muscle blocks, a caudal fin, features that they share with jawless vertebrates. But<br />

they also possess a mineralized dermal skeleton, which is considered as gnathostome apomorphy.<br />

That shows that within the Conodonta fossil groups of different origin might be lumped and that<br />

Euconodonta may be more closely related to living jawed vertebrates rather than to lampreys. The<br />

only way to learn more about the true nature of conodonts is the discovery of additional natural<br />

assemblages and the examination of diagenetic processes affecting hard and soft tissue during<br />

fossilization (e.g. solution of calcium carbonate, emplacement of phosphate).<br />

Morphological and genetic analysis of moss-dwelling<br />

tardigrades<br />

Übelleitner, B. & Weiss, S.<br />

1 Institute of Zoology, University of Graz, Universitätsplatz 2, 8010 Graz, bybeatecom@yahoo.de<br />

Tardigrades, or water bears, are a diverse phylum of microscopic invertebrates that have existed since<br />

the Cambrian. They are especially noted for being polyextremophilic existing both in hot springs as<br />

well as in solid ice. They are among the few organisms capable of suspending metabolism and<br />

entering a state of cryptobiosis. To date there are approximately 1000 described species although it is<br />

widely recognized that the group has attracted little research attention and their diversity is thus vastly<br />

underestimated. The armored tardigrades, or Heterotardigrades, have morphological characteristics<br />

such as cephalic appendages, cuticular extensions, claws and the pattern of dorsal cuticular plates,<br />

whereas the main characteristics of the naked tardigrades (Eutardigrade) are claws, the<br />

buccopharyngeal apparatus and a cuticle structure, which can be smooth, granulated or bearing<br />

tubercles. The phrase "naked" refers to the absence of cuticular dorsal plates, which are present in<br />

Heterotardigrada. We investigated a total of 192 moss samples from both man-made (botanical<br />

gardens) and natural habitats (Graz vicinity) for the presence of tardigrades. From a total of 88 moss<br />

samples with tardigrades, 104 individual slide preparations were made for morphological evaluation.<br />

Nearly all preparations (N = 103) could be assigned to the genus level, whereby 59 individuals were<br />

assigned to one of six species. An additional four species were determined with the aid of an mtDNA<br />

sequence (COI gene). Eutardigrades dominated the collected moss samples with Macrobiotus as the<br />

most frequent genus and Macrobiotus cf. hufelandi (N = 47) as the most common species.<br />

Macrobiotus cf. hufelandi was found at different altitudinal levels in Styria, whereas other species were<br />

only found in specific locations. There was no apparent species-specific relationship between moss<br />

and tardigrade taxa and there was no apparent relationship between the colonization of tardigrades<br />

and various man-made substrates within the botanical gardens. Further molecular genetic analysis<br />

was hindered by the extreme divergence of the group, and thus lack of universal primers for species-<br />

level identification. Based on our own phylogenetic reconstruction of available GenBank sequences it<br />

is clear that the current systematic and taxonomic assignment of tardigrades requires substantial<br />

revision.<br />

Is Babesia still Babesia?<br />

Walochnik, J. & Aspöck, H.<br />

Molecular Parasitology, Institute of Specific Prophylaxis and Tropical Medicine, Medical University of<br />

Vienna, Kinderspitalgasse 15, 1090 Vienna, e-mail: julia.walochnik@meduniwien.ac.at<br />

The babesias belong to the Apicomplexa (Alveolata; Eukaryota), as do the causative agents of<br />

malaria. Likewise they also parasitize red blood cells of vertebrates. Human babesiosis is a zoonosis<br />

transmitted by ixodid ticks, in which the relevant hosts are bovines, other mammals, and also birds.<br />

Most human cases are caused either by Babesia divergens, which occurs exclusively in Europe, or B.<br />

microti, which mainly occurs in the northeastern eastern parts of the USA.<br />

In 1888 the Romanian pathologist Victor Babes described Haematococcus bovis, a blood parasite of<br />

cattle. Later he found a similar parasite in the blood of sheep and named it H. ovis. One year after<br />

Babes’ first description, Smith and Kilbourne, described Pyrosoma bigeminum (later re-described as<br />

Piroplasma bigeminum) isolated from blood specimens of cattle suffering from Texas fever. Finally, the<br />

genus Babesia was established by Starcovici in 1893, uniting B. bovis and B. ovis, and later also<br />

including B. bigemina.<br />

Meanwhile, more than 100 species have been described, mainly according to their respective<br />

vertebrate hosts. In the past years, however, the validity of many species has been questioned and<br />

also new species have been described, including B. venatorum, Herwaldt et al. 2003 and B. duncani<br />

Conrad et al. 2006, both isolated from humans. Moreover, it has been shown that B. microti is more<br />

closely related to the genus Theileria than to other Babesia species. According to molecular data, five<br />

distinct groups can be discriminated within the Piroplasmidae: Babesia sensu stricto I, Babesia sensu<br />

stricto II, Babesia microti group, Theileria-like group and Theileria sensu stricto.<br />

Three cases of human babesiosis have been described in <strong>Austria</strong>, two caused by to the newly<br />

described species B. venatorum (Herwaldt et al. 2003, Gattringer et al. in preparation) and one by B.<br />

microti (Ramharter et al. <strong>2010</strong>).<br />

The taxon Odontophora has recently been established and comprises camarodont sea urchins with a<br />

distinct skeletal protrusion on the epiphysis. This process, termed tooth support, lies on the adaxial<br />

edge of the wing of the epiphysis and flanks the proximal part of the sea urchin tooth at the point<br />

where the plumula merges with the solid tooth shaft. Although the function of the tooth support is still<br />

unknown, it constitutes a skeletal feature that can be easily observed both in fossil as well as extant<br />

material and could therefore be useful for classification purposes. Originally, three taxa are included in<br />

the Odontophora: the Echinometridae, the Strongylocentrotidae, and the Toxopneustidae. Although<br />

closely related to the former taxa, the Parasaleniidae, the Parechinidae, and the Echinidae were<br />

excluded based on the absence of a tooth support as well as other characters. Here, we try to show<br />

whether the hypothetical grouping based on a cladistic analysis on the family level also holds true on<br />

the genus level. We combined classical dissection and SEM imaging of skeletal structures with µCT<br />

imaging of whole specimens, thereby improving our understanding of the position and potential<br />

function of the tooth support. Representatives of almost all extant genera of the Odontophora were<br />

examined. Further results, acquired using magnetic resonance imaging (MRI), strongly indicate that<br />

there is indeed independent anatomical support for the taxon Odontophora, as exemplified by the<br />

presence of highly specialised protractor muscles present in the Echinometridae, the<br />

Strongylocentrotidae, and the Toxopneustidae.<br />
