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.

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.

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.

  • 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.

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.

  • Which Physella (Mollusca: Gastropoda) Lives in the Czech Republic?
    Acta Soc. Zool. Bohem. 68: 241–243, 2004 ISSN 1211-376X Which Physella (Mollusca: Gastropoda) lives in the Czech Republic? LUBOŠ BERAN Kokořínsko Protected Landscape Area Administration, Česká 149, CZ–276 01 Mělník, Czech Republic; e-mail: [email protected] Received January 23, 2004; accepted March 5, 2004 Published August 31, 2005 Abstract. For the first time in the Czech Republic specimens belonging to the genus Physella Haldeman, 1843 were dissected to help in the identification of the species living here. Specimens collected from 11 sites situated in the Czech Republic were dissected. Occurrence of Physella gyrina (Say, 1821), a mollusc introduced in Great Britain from North America, has not been documented in the Czech Republic yet and the results presented here indicate that only one species of the genus Physella occurs in the Czech Republic. Distribution, Mollusca, Gastropoda, Physella acuta, Physella heterostropha, Palaearctic region INTRODUCTION The first specimens of the genus Physella Haldeman, 1843 were found by J. Brabenec in 1919 in Prague, Czech Republic (Beran 2002). There has been a quick increase in the recording of Physella, especially since 1990. Currently this taxon is known from a large part of the Czech Republic, occurring mainly on the floodplains of large rivers such as the Elbe, Dyje, Morava and Odra (Fig. 1). This mollusc inhabits mainly man-made habitats (sandpits, ponds) and is also able to live in very polluted water e. g. in sewage treatment plants (Mácha 1971). Specimens of the genus Physel- la were not dissected in the Czech Republic before 2003 and were usually determined as Physella acuta (e.
