The molecular phylogeny based on the combined dataset indicates that Margarya is polyphyletic, as two of the three well-supported clades containing species of Margarya also comprise species from other viviparid genera. In one clade, sequences of four species of Margarya even cluster indiscriminately with those of two species of Cipangopaludina, indi- cating that the current state of Asian viviparid taxonomy needs to be revised. Additionally, these data suggest that shell evolution in viviparids is complex, as even the large and strongly sculptured shells of Margarya, which are outstanding among Asian viviparids, can apparently be easily converted to simple smooth shells. -

Fasciolosis is water and food borne disease, caused by Fasciola hepatica and F. gigantica.SnailLymnaea acuminata is an intermediate host of these flukes. Snail control is one of the major methods to reduce the incidences of fasciolosis. Trapping of snails withthe help of photo- and chemoattractants for treatment purposes will be a new tool in control program of fasciolosis. The present study shows that maximum numbers of snails were attracted (52 to 60%), when exposed to photo- and chemostimulant simultaneously, rather than when only chemo- (control) (18 to 24%) or photo- (control) (14 to 19%) stimulus was given. Maximum change in AChE activity in nervous tissue was observed when red monochromatic light was used (258.37% of white light control) as opposed to blue (243.44% of white light control) and orange (230.37% of white light control). -

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. -

L. Khan Women’s College, Angsuman Chanda Midnapur, Paschim Medinipur, West Bengal, India Abstract A survey was conducted to explore the indigenous Freshwater of undivided Paschim Medinipur District of West Bengal during May 2013 to November 2015. Mollusc as The present study results revealed that freshwater ecosystem of undivided Paschim Medinipur represents existence of nine species of edible mollusks under eight genera of six families and four orders. Out of these nine species four species namely Bellamya bengalensis (Lamarck,1882, Pila globosa (swainson, 1828), Lamellidens marginalis (Lamarck, 1819) and Lymnaea acuminata (Lamarck, 1822) are most abundant and found in all most all twenty nine revenue blocks of undivided Paschim Medinipur District. Present work is the first report of indigenous freshwater molluscan diversity of the study area. Keywords: Freshwater, molluscs, diversity, Paschim Medinipur 1. Introduction Molluscs contribute second largest world biodiversity among and most successful group of [1, 2] invertebrate next to insects . The estimated molluscan species ranges from 80,00 to 135,000 Boss [3] and Van Bruggen [4] estimated the same ranges 50,000-200,000. Seddon [5] reported 5000 freshwater species of molluscs. Majority of the freshwater species of West Bengal are regarded as supplementary food resources of village people as well as urban citizen. -
Gross Anatomy of the Reproductive System of Freshwater Pulmonate Snail Lymnaea Acuminata (Gastropoda: Pulmonata)

Corresponding Author: *3 Sherkhane UD, e-mail: [email protected] ABSTRACT The present research paper provides an account of gross anatomy of reproductive system in snail L. acuminata. Results obtained shows that the reproductive system of L. acuminata consists of three divisions: (1) The ovotestis or hermaphroditic gland and its duct i.e., the hermaphroditic duct, (2) The female genital tract and (3) The male genital tract. The female duct system consists of the oviduct, the uterus, the vagina and associated accessory glands which include the albumen gland, the muciparous gland and oothecal gland. The male duct system consists of the vas efferens, the prostate gland, vas deferens and the copulatory organ the Penial complex. We hope that the results obtained will be highly useful to understand reproductive anatomy and taxonomy of freshwater gastropods. Key Words: Lymnaea acuminata, Anatomy, Reproductive system. INTRODUCTION Freshwater pulmonate snail Lymnaea acuminata Lamarck, 1822 (Mollusca: Gastropoda: Pulmonata) is abundantly available in various parts of Indian subcontinent (Subba Rao, 1989). The reproductive system of freshwater gastropods varies greatly from one group to another and their reproductive strategies also vary greatly. A considerable diversity exists in the internal anatomy of the reproductive tracts of gastropods which is of taxonomic importance. -
The Growth and Reproduction of the Freshwater Limpet
The Growth and Reproduction of the Freshwater Limpet Burnupia stenochorias (Pulmonata, Ancylidae), and An Evaluation of its Use As An Ecotoxicology Indicator in Whole Effluent Testing A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY of RHODES UNIVERSITY by HEATHER DENISE DAVIES-COLEMAN September 2001 ABSTRACT For the protection of the ecological Reserve in South Africa, the proposed introduction of compulsory toxicity testing in the licensing of effluent discharges necessitates the development of whole effluent toxicity testing. The elucidation of the effects of effluent on the local indigenous populations of organisms is essential before hazard and risk assessment can be undertaken. The limpet Burnupia stenochorias, prevalent in the Eastern Cape of South Africa, was chosen to represent the freshwater molluscs as a potential toxicity indicator. Using potassium dichromate (as a reference toxicant) and a textile whole effluent, the suitability of B. stenochorias was assessed under both acute and chronic toxicity conditions in the laboratory. In support of the toxicity studies, aspects of the biology of B. stenochorias were investigated under both natural and laboratory conditions. Using Principal Component and Discriminant Function Analyses, the relative shell morphometrics of three feral populations of B. stenochorias were found to vary. Length was shown to adequately represent growth of the shell, although the inclusion of width measurements is more statistically preferable. Two of the feral populations, one in impacted water, were studied weekly for 52 weeks to assess natural population dynamics. Based on the Von Bertalanffy Growth Equation, estimates of growth and longevity were made for this species, with growth highly seasonal. -
