The ﬁsh genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose. Some of the forms that originated in the Paratethys colonized the Mediterranean, and overwhelming data indicate that Citation: Artamonova, V.S.; Bolotov, representatives of the genera Salmo, Caspiomyzon, and Ecrobia migrated during the Miocene from I.N.; Vinarski, M.V.; Makhrov, A.A.

In order to gain the first quantitative insight into this behaviour, we have quantified the proportion of individuals bearing egg clutches in a long-term monospecific outdoor laboratory culture of L. stagnalis during two consecutive late-summer months. The snails were assigned to size classes based on shell height. Differences between the size class composition of clutch-bearers and of the general population were statistically compared by means of Pearson’s distance χ²P analysis. Egg clutches were laid on snails of shell height >15 mm (i.e. reproductive-age individuals), with significant selection for the larger size classes (shell height 25–40 mm). While the mechanisms of and reasons behind such behaviour remain unknown, selection of larger adults as egg-carriers may have ecological implications at the population level.

The same results showed that Stagnicola palustris (O. F. Müll.) and S. turricula (Held) could also be treated as separate species, but compared to the aforementioned lymnaeids, the differences in the analysed sequences between them were much smaller, although clearly recognisable. In each case they were also larger than the differences between these molecular features of specimens from different localities of S. palustris or S. turricula. New data on the distribution of S. palustris and S. turricula in Poland showed – in contrast to the earlier reports – that their ranges overlapped. This sympatric distribution together with the small but clearly marked differences in molecular features as well as with differences in the male genitalia between S.

Gyraulus Laevis in Nederland 87
Kuijper: Gyraulus laevis in Nederland 87 Gyraulus laevis (Mollusca: Planorbidae) in Nederland door W.J. Kuijper Enkele recente waarnemingen van een van onze zeldzaamste planorbiden waren de aanleiding tot het samenstellen van een over- laevis zicht van alle van Nederland bekende vondsten van Gyraulus (Alder, 1838). Tot voor kort waren slechts enkele vindplaatsen van dit dier bekend (Janssen & De Vogel, 1965: 75). Hierbij komt het betrof feit dat het in een aantal gevallen slechts een enkel exemplaar en de soort niet meer teruggevonden kon worden. Het volgende geeft een chronologisch overzicht van de waarnemingen van Gyraulus laevis in Nederland. Voor zover beschikbaar zijn diverse gegevens van de vindplaatsen vermeld. WAARNEMINGEN 1. Koudekerke (bij Middelburg), buitenplaats Vijvervreugd, ± 1890. Fraai vers materiaal: 69 exemplaren in de collectie Schep- de man (Zoölogisch Museum, Amsterdam). Later niet meer vermeld, buitenplaats bestaat niet meer (Kuiper, 1944: 6). Dit materiaalwerd verzameld door Dr. IJ. Keijzer en is vermeld in: Verslag over 1885-1893 van het Zeeuwsch Genootschap der Wetenschappen, blz. 88 (volgens Mevr. Dr. W.S.S. van der Feen - van Benthem Jut- ting). Verder is materiaal van deze vindplaats in de collecties van het Zeeuwsch Museum te Middelburg (2 ex.) en het Natuurhistorisch Museum te Enschede (6 ex.) aanwezig. 2. Warmond (bij Leiden), in de Leede, januari 1916 (Van Ben- them Jutting, 1933: 179). Dit materiaal werd verzameld door P.P. de Koning; in het Rijksmuseum van Natuurlijke Historie te Leiden bevinden zich vier schelpen van deze vindplaats, waarvan twee een doorsnede van ca. 4 mm bereiken. 3.

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.

DNA Multigene Sequencing of Topotypic Specimens of the Fascioliasis Vector Lymnaea Diaphana and Phylogenetic Analysis of the Genus Pectinidens (Gastropoda)
Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 107(1): 111-124, February 2012 111 DNA multigene sequencing of topotypic specimens of the fascioliasis vector Lymnaea diaphana and phylogenetic analysis of the genus Pectinidens (Gastropoda) Maria Dolores Bargues1/+, Roberto Luis Mera y Sierra2, Patricio Artigas1, Santiago Mas-Coma1 1Departamento de Parasitología, Facultad de Farmacia, Universidad de Valencia, Av. Vicente Andrés Estellés s/n, 46100 Burjassot, Valencia, Spain 2Cátedra de Parasitología y Enfermedades Parasitarias, Facultad de Ciencias Veterinarias, Universidad Juan Agustín Maza, Guaymallén, Mendoza, Argentina Freshwater lymnaeid snails are crucial in defining transmission and epidemiology of fascioliasis. In South Amer- ica, human endemic areas are related to high altitudes in Andean regions. The species Lymnaea diaphana has, how- ever, been involved in low altitude areas of Chile, Argentina and Peru where human infection also occurs. Complete nuclear ribosomal DNA 18S, internal transcribed spacer (ITS)-2 and ITS-1 and fragments of mitochondrial DNA 16S and cytochrome c oxidase (cox)1 genes of L. diaphana specimens from its type locality offered 1,848, 495, 520, 424 and 672 bp long sequences. Comparisons with New and Old World Galba/Fossaria, Palaearctic stagnicolines, Nearctic stagnicolines, Old World Radix and Pseudosuccinea allowed to conclude that (i) L. diaphana shows se- quences very different from all other lymnaeids, (ii) each marker allows its differentiation, except cox1 amino acid sequence, and (iii) L. diaphana is not a fossarine lymnaeid, but rather an archaic relict form derived from the oldest North American stagnicoline ancestors. Phylogeny and large genetic distances support the genus Pectinidens as the first stagnicoline representative in the southern hemisphere, including colonization of extreme world regions, as most southern Patagonia, long time ago.

Freshwater Snail Guide
A Beginner’s Guide to Freshwater Snails of Central Scotland Freshwater snails are a diverse and fascinating group of molluscs found in ponds, lochs, canals, rivers and watery ditches all across the globe. This guide is a simple introduction to some of the most commonly encountered and easily identifiable freshwater snail species in Central Scotland. How do I look for freshwater snails? 1) Choose your spot: anywhere with water – your garden pond, a nearby river, canal or loch – is likely to have snails. 2) Grab a pond net (buy online or make your own by attaching a sieve to the end of an old broom or mop), a white tray or tub and a hand-lens or magnifier. 3) Fill the tray with water from your chosen habitat. Sweep the net around in the water, making sure to get among any vegetation (don’t go too near the bottom or you’ll get a net full of mud), empty your net into the water-filled tray and identify what you have found! Snail shell features Spire Whorls Some snail species have a hard plate called an ‘operculum’ Height which they Mouth (Aperture) use to seal the mouth of the shell when they are inside Height Pointed shell Flat shell Width Width Pond Snails (Lymnaeidae) Variable in size. Mouth always on right-hand side, shells usually long and pointed. Great Pond Snail Common Pond Snail Lymnaea stagnalis Radix balthica Largest pond snail. Common in ponds Fairly rounded and ’fat’. Common in weedy lakes, canals and sometimes slow river still waters. pools.
