Anisus Vorticulus (Troschel 1834) (Gastropoda: Planorbidae) in Northeast Germany
JOURNAL OF CONCHOLOGY (2013), VOL.41, NO.3 389 SOME ECOLOGICAL PECULIARITIES OF ANISUS VORTICULUS (TROSCHEL 1834) (GASTROPODA: PLANORBIDAE) IN NORTHEAST GERMANY MICHAEL L. ZETTLER Leibniz Institute for Baltic Sea Research Warnemünde, Seestr. 15, D-18119 Rostock, Germany Abstract During the EU Habitats Directive monitoring between 2008 and 2010 the ecological requirements of the gastropod species Anisus vorticulus (Troschel 1834) were investigated in 24 different waterbodies of northeast Germany. 117 sampling units were analyzed quantitatively. 45 of these units contained living individuals of the target species in abundances between 4 and 616 individuals m-2. More than 25.300 living individuals of accompanying freshwater mollusc species and about 9.400 empty shells were counted and determined to the species level. Altogether 47 species were identified. The benefit of enhanced knowledge on the ecological requirements was gained due to the wide range and high number of sampled habitats with both obviously convenient and inconvenient living conditions for A. vorticulus. In northeast Germany the amphibian zones of sheltered mesotrophic lake shores, swampy (lime) fens and peat holes which are sun exposed and have populations of any Chara species belong to the optimal, continuously and densely colonized biotopes. The cluster analysis emphasized that A. vorticulus was associated with a typical species composition, which can be named as “Anisus-vorticulus-community”. In compliance with that both the frequency of combined occurrence of species and their similarity in relative abundance are important. The following species belong to the “Anisus-vorticulus-community” in northeast Germany: Pisidium obtusale, Pisidium milium, Pisidium pseudosphaerium, Bithynia leachii, Stagnicola palustris, Valvata cristata, Bathyomphalus contortus, Bithynia tentaculata, Anisus vortex, Hippeutis complanatus, Gyraulus crista, Physa fontinalis, Segmentina nitida and Anisus vorticulus. -

Czaja) Received: 14 April 2019; accepted: 6 November 2019 Abstract We present an updated checklist of native Mexican freshwater gastropods with data on their general distribution, hotspots of endemicity, threats, and for the first time, their estimated conservation status. The list contains 193 species, representing 13 families and 61 genera. Of these, 103 species (53.4%) and 12 genera are endemic to Mexico, and 75 species are considered local endemics because of their restricted distribution to very small areas. Using NatureServe Ranking, 9 species (4.7%) are considered possibly or presumably extinct, 40 (20.7%) are critically imperiled, 30 (15.5%) are imperiled, 15 (7.8%) are vulnerable and only 64 (33.2%) are currently stable. -

Aplexa Hypnorum (Gastropoda: Physidae) Exerts Competition on Two Lymnaeid Species in Periodically Dried Ditches
Ann. Limnol. - Int. J. Lim. 52 (2016) 379–386 Available online at: Ó The authors, 2016 www.limnology-journal.org DOI: 10.1051/limn/2016022 Aplexa hypnorum (Gastropoda: Physidae) exerts competition on two lymnaeid species in periodically dried ditches Daniel Rondelaud, Philippe Vignoles and Gilles Dreyfuss* Laboratory of Parasitology, Faculty of Pharmacy, 87025 Limoges Cedex, France Received 26 November 2014; Accepted 2 September 2016 Abstract – Samples of adult Aplexa hypnorum were experimentally introduced into periodically dried ditches colonized by Galba truncatula or Omphiscola glabra to monitor the distribution and density of these snail species from 2002 to 2008, and to compare these values with those noted in control sites only frequented by either lymnaeid. The introduction of A. hypnorum into each ditch was followed by the progressive coloni- zation of the entire habitat by the physid and progressive reduction of the portion occupied by the lymnaeid towards the upstream extremity of the ditch. Moreover, the size of the lymnaeid population decreased significantly over the 7-year period, with values noted in 2008 that were significantly lower than those recorded in 2002. In contrast, the mean densities were relatively stable in the sites only occupied by G. truncatula or O. glabra. Laboratory investigations were also carried out by placing juvenile, intermediate or adult physids in aquaria in the presence of juvenile, intermediate or adult G. truncatula (or O. glabra) for 30 days. The life stage of A. hypnorum had a significant influence on the survival of each lymnaeid. In snail combinations, this survival was significantly lower for adult G. truncatula (or O. -

In 1942 this species was found in the Czech Republic for the first time and a total of 155 species records were obtained by the end of 2005. Based on distribution data, we observed the gradual expansion of this gastropod not only in the Elbe Lowland, where its occurrence is concentrated, but also in other regions of the Czech Republic particularly between 2001 and 2005. Information on habitat, altitude and co-occurrence with other molluscs are presented. Key words: alien species, Czech Republic, distribution, Ferrissia fragilis, habitats Introduction used for all specimens of the genus Ferrissia found in the Czech Republic. Probably only one species of the genus Ferrissia Records of the genus Ferrissia exist from all (Walker, 1903) occurs in Europe.

New Substitute Names for Two Preoccupied Tachinid Genera Paragonia Mesnil, 1950 and Menetus Aldrich, 1926 (Diptera)
_____________Mun. Ent. Zool. Vol. 1, No. 2, June 2006__________ 270 NEW SUBSTITUTE NAMES FOR TWO PREOCCUPIED TACHINID GENERA PARAGONIA MESNIL, 1950 AND MENETUS ALDRICH, 1926 (DIPTERA) Hüseyin Özdikmen* * Department of Biology, Faculty of Science and Arts, University of Gazi, 06500 Ankara / Turkey, e-mail: [email protected] [Özdikmen, H. 2006. New substitute names for two preoccupied Tachinid genera Paragonia Mesnil, 1950 and Menetus Aldrich, 1926 (Diptera). Munis Entomology & Zoology, 1 (2): 270-272] ABSTRACT: Two junior homonyms were detected amongst the Tachinidae and the following replacement names are proposed: Mesnilius for Paragonia Mesnil, 1950 and Aldrichomyia for Menetus Aldrich, 1926. Accordingly, new combinations are herein proposed for the type species currently included in monotypic genera Paragonia Mesnil, 1950 and Menetus Aldrich, 1926. Keywords: Mesnilius, Paragonia, Aldrichomyia, Menetus, homonymy, replacement names TAXONOMY Order Diptera Family Tachinidae Mesnilius nom. nov., substitute name Paragonia Mesnil, 1950. In Lindner, Flieg. palaearkt. Reg. Stuttgart, 64g, 106 (1950). (Diptera: Tachinidae: Goniinae: Sturmiini). Preoccupied by Paragonia Huebner, [1823]. Verz. bekannt. Schmett., (19) 292. (Lepidoptera: Geometroidea: Geometridae: Ennominae). Remarks: Mesnil (1950) proposed the genus Paragonia with the type species Paragonia portentosa Mesnil, 1950 by original designation in the fly family Tachinidae (Diptera) (Cantrell & Crosskey, 1989; Evenhuis, 1996; O’Hara & Wood, 2004; O’Hara, 2005). Unfortunately, the generic name was already preoccupied by Huebner (1823), who had described the genus Paragonia with the type species Phalaena tasima Cramer, 1779 by monotypy in the moth family Geometridae (Lepidoptera). Scoble et al. (1999) included 9 species and 2 subspecies (inc. nominates) in the genus Paragonia Huebner, 1823 and also Clysia Guenée, 1858 as a junior synonym of the genus Paragonia. -

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.
