“…Although males have been reported to occur in a few locations in Europe (Wallace 1979(Wallace , 1985, there is no evidence for sexual reproduction, and European P. antipodarum appear to be strictly parthenogenetic. Three morphologically distinguishable genetic strains of P. antipodarum have been described in Britain (labelled A, B, C; Warwick 1952Warwick , 1969Hauser et al 1992), and a relationship between habitat and strain has been reported, with B being found in coastal areas whereas A is most often found in inland locations. Strain C is a relatively rare morphotype only found in Wales and a few locations on continental Europe (Warwick 1952(Warwick , 1969.…”

Summary1. Parthenogenetic species are often geographically more widely distributed than their sexual relatives. This success in colonizing can be explained either by dispersal of one or a few clones of wide physiological tolerance or by the distribution of many locally adapted clones. 2. Here we compare the influence of salinity on reproductive output, feeding rate, growth rate and size at birth between two genotypes of Potamopyrgus antipodarum to address the questions (i) Do these traits vary in response to changing salinity? (ii) Does the response to a salinity gradient differ between genotypes? (iii) Can the patterns of variation, in relation to salinity, contribute to explaining the geographical distribution of P. antipodarum in Europe? 3. Our results demonstrate that genetic variation among populations of P. antipodarum is reflected in differences in life-history traits and feeding rates in response to a salinity gradient. The phenotypic differences between the genotypes are consistent with the geographical distribution of P. antipodarum clones in Europe. 4. The overall response to salinity of both genotypes of P. antipodarum suggests an optimum at ≈ 5‰ S; however, both genotypes showed a broad salinity tolerance and were able to feed, grow and reproduce over the entire salinity range tested (0-15‰ S). The broad environmental tolerance of both genotypes together with their widespread geographical distribution across Europe provide evidence consistent with the generalpurpose genotype hypothesis.

“…Similar effects were seen in other regionsfor example, ivory shell Babylonia japonica populations in Japan declined significantly approximately 2 years after TBT-related imposex was first observed (Horiguchi et al, 2006). Although Franc (1940;1952) formerly had no problems in capturing hundreds of egg capsules and also large numbers of adult Ocinebrina aciculata on the north coast of Brittany (France), Oehlmann et al (1996) reported a serious population decline for this species between the Bay of Arcachon and Luc-sur-Mer (north of Bayeux) over a period of several years.…”

“…More than 50 years ago Warwick (1952) reported on three different morphotypes (A, B, C) identified in British Potamopyrgus jenkinsi populations. Strains are morphologically distinguishable, and exhibit different ecological and physiological preferences (Jacobsen and Forbes 1997;Son et al 2008, Warwick 1952 and it was assumed that all European Potamopyrgus snails belong to the New Zealand species P. antipodarum with the existence of very few clonal lineages in Europe (Städler et al 2005).…”

Observers from several countries with special status at the OECD, and from interested international organisations, attend many of the OECD's workshops and other meetings. Committees and working groups are served by the OECD Secretariat, located in Paris, France, which is organised into directorates and divisions. IV.Although there are some similarities between the endocrine systems of vertebrates and molluscs, the lack of knowledge about how EDCs act in molluscs currently prevents the use of mollusc-based tests as surrogates for tests with aquatic vertebrates such as fish.V. Given our relatively poor understanding of molluscan endocrinology, it is not currently possible to recommend the development of mollusc-based screening tests for the identification of EDCs. On the other hand, we are now in a position to start standardising apical mollusc tests involving partial or full lifecycle exposures. In principle, these are expected to be responsive to any chemicals (EDCs or nonEDCs) with activity in molluscs, even though they may not provide diagnostic information on modes of action (MoA). VI.The review recommends three apical test procedures for optimisation and possible validation. The first is a partial life cycle (PLC) test with the freshwater gastropod Potamopyrgus antipodarum, the second is a full li...

Adaptive phenotypic plasticity in a clonal invader

Organisms featuring wide trait variability and occurring in a wide range of habitats, such as the ovoviviparous New Zealand freshwater snail Potamopyrgus antipodarum, are ideal models to study adaptation. Since the mid‐19th century, P. antipodarum, characterized by extremely variable shell morphology, has successfully invaded aquatic areas on four continents. Because these obligately and wholly asexual invasive populations harbor low genetic diversity compared to mixed sexual/asexual populations in the native range, we hypothesized that (1) this phenotypic variation in the invasive range might be adaptive with respect to colonization of novel habitats, and (2) that at least some of the variation might be caused by phenotypic plasticity. We surveyed 425 snails from 21 localities across northwest Europe to attempt to disentangle genetic and environmental effects on shell morphology. We analyzed brood size as proxy for fitness and shell geometric morphometrics, while controlling for genetic background. Our survey revealed 10 SNP genotypes nested into two mtDNA haplotypes and indicated that mainly lineage drove variation in shell shape but not size. Physicochemical parameters affected both shell shape and size and the interaction of these traits with brood size. In particular, stronger stream flow rates were associated with larger shells. Our measurements of brood size suggested that relatively larger slender snails with relatively large apertures were better adapted to strong flow than counterparts with broader shells and relatively small apertures. In conclusion, the apparent potential to modify shell morphology plays likely a key role in the invasive success of P. antipodarum; the two main components of shell morphology, namely shape and size, being differentially controlled, the former mainly genetically and the latter predominantly by phenotypic plasticity.
