This checklist contains 73 species from 34 genera and 14 families of freshwater snails; 27 of these species (37%) are endemic to Iran.

Malak. Abh. 23: 3–26 3 Kommentierte Artenliste der Süßwassermollusken Deutschlands PETER GLÖER 1 & MICHAEL L. ZETTLER 2 1 Schulstrasse 3, D-25491 Hetlingen, Germany; [email protected] 2 Institut für Ostseeforschung Warnemünde, Seestr. 15, D-18119 Rostock, Germany; [email protected] Abstract. An annotated check-list of the freshwater molluscs of Germany. – By considering the international code of zoological nomenclature, a critical annotated check-list for the freshwater molluscs of Germany is introduced, considering the currently used check-lists of GLÖER & MEIER- BROOK (1998), FALKNER et al. (2001), GLÖER (2002) und GLÖER & MEIER-BROOK (2003). As a basis of this list we used the CLECOM list (FALKNER & al. 2001), and the 1st update of the CLECOM list (BANK et al. 2001). In total 66 taxa are discussed or annotated. Meanwhile 15 taxa where deleted, because we do not think that these are distinct species or subspecies. This concerns particularly the subspecies of the Unionidae, which are not to be determinated seriously without the knowledge of the sampling site. In 5 taxa we changed the names given in the CLECOM list by established names, these are: Bithynia transsilvanica = B. troschelii, Anisus septemgyratus = A. leucostoma, A. calculiformis = A. septemgyratus, Ferrissia clessiniana = F. wautieri, Mytilopsis leucophaeata = Congeria leucophaeata. Finally we gave two subspecies the rank of species: Pisidum ponderosum and Pisidium crassum. Kurzfassung. Unter Beachtung der internationalen Regeln für die zoologische Nomenklatur, wird auf der Basis der derzeit verwendeten systematischen Listen von GLÖER & MEIER-BROOK (1998), FALKNER et al. (2001), GLÖER (2002) und GLÖER & MEIER-BROOK (2003) eine kritische, kommentierte Artenliste für die Süßwassermollusken in Deutschland vorgestellt. -

Species Composition of Macroinvertebrates in Medium-Sized Lithuanian Rivers
10 Acta Zoologica Lituanica, 2004, Volumen 14, Numerus 3 ISSN 1392-1657 SPECIES COMPOSITION OF MACROINVERTEBRATES IN MEDIUM-SIZED LITHUANIAN RIVERS Virginija PLIÛRAITË, Vytautas KESMINAS Institute of Ecology of Vilnius University, Akademijos 2, LT-08412 Vilnius-21, Lithuania. E-mail: [email protected], [email protected] Abstract. The article is devoted to the analysis of the taxonomic composition of macroinvertebrates in 17 medium-sized Lithuanian rivers with different kinds of substrata. One hundred and sixty taxa of invertebrates were identified in the course of the study. The obtained results proved that in the same river the number of taxa and Shannon-Weavers index of diversity are substratum type dependent. The greatest number of taxa was established in the stone substratum while the smallest was recorded in the sand one. The richest biodiversity and the highest Shannon-Weavers index in the stone substratum were recorded in the Jiesia River. Rivers with increased organic contamination were dominated by Trichoptera of the genus Hydropsyche.

Freshwater Snails (Mollusca: Gastropoda) of Bulgaria: an Updated Annotated Checklist

The total num- ber of freshwater snail species hitherto recorded from Bulgaria is 120. Three species are regarded as extinct, two species were found only as subfossil remains. The most diverse families are Hydrobiidae (67 species), Planorbidae (15), and Lymnaeidae (11). The remaining families are represented by 1 to 4 species. Zoogeo- graphical, ecological and conservation data are discussed. KEY WORDS: Bulgaria, freshwater, distribution, ecology, conservation INTRODUCTION The Balkan malacofauna is much less well studied, and data on their distribution, was soon followed by compared to that of Western Europe, whereas at the HUBENOV’s (2005, 2007a) lists of the known Bulgar- same time it seems to be much richer (GLÖER & ian species, with an emphasis on their distribution DIERCKING 2010, WELTER-SCHULTES 2012).

In the year 2007, a complex study was conducted on river Bodrog in the spring and once again in the summer. We sampled the river in 9 sampling units along the whole Hungarian section. The quantitative sampling method which we have used, meets the requirements of the WFD. The freshwater molluscs was one of the 10 examined macroin- vertebrate taxa. As a result of the examination we have confirmed the presence of 17 snail and 12 shell-fish species. Out of these the following three, the Acroloxus lacustris, the Sinanodonta woodiana, and the Pisidium henslowanum proved to be new for the fauna of the river. Analysing the quantitative samples it became clear that the number of species and the number of the individuals are not homogeneous along the river. The num- ber of species per surface unit is growing down the river. Moreover the closer you get to the mouth of the river the stagnofil, extensive reed-grass stand related, grazing freshwater snail species are becoming more involved. The presence and the growing density of these species are likely results of the Tiszalök dike's damming affect. The reofil species density changes are the opposite of the stagnofil species density changes. Key words: Bodrog, molluscs, macroinvertebrates, quantitative survey, WFD, damming.
