“…Five genes were chosen for amplification, with varying expected levels of conservation, and are commonly used in gastropod family level phylogenies (Colgan et al, 2007;Jorgensen et al, 2008;Sengupta et al, 2009). By using genes from a variety of sources, we help ensure that we are not simply analyzing the evolution of a single gene, but of the species themselves.…”

“…Bellamya are important pollution bioindicators for freshwater systems and represent an ideal system for the study of environmental toxicology (Chen et al, 2005;Li et al, 2012). These snails are also reported to be widespread invasive species in North American and African lakes (Sengupta et al, 2009;Solomon et al, 2010). Because Bellamya is a species-rich genus of primarily sessile freshwater snails that is widely distributed across Southeast Asia, India and Africa, it is a suitable model system for the study of population genetics and biological evolution (Sengupta et al, 2009;Schultheiβ et al, 2011;Van Bocxlaer and Hunt, 2013).…”

ABSTRACT. Bellamya is a widely distributed freshwater snail genus in China; however, its genetic diversity is completely unknown. Sixtyfive novel microsatellite loci were isolated and characterized from a microsatellite-enriched library of Bellamya aeruginosa genomic DNA. Most of the 65 loci were successfully amplified. We found high polymorphic information content values for these loci, ranging from 0.235 to 0.892. There were 3 to 12 alleles per locus, and the H E and H O varied from 0.425 to 0.953 and 0.026 to 1.000, respectively. Fifteen loci deviated significantly from Hardy-Weinberg equilibrium after Bonferroni's correction. All 65 SSR markers were tested in an additional five Bellamya species, and 96.9% of the 325 locus/taxon combinations tested resulted in cross-species amplification. Seven polymorphic microsatellite markers were randomly selected for comparison among nine populations of three species. All populations had moderate to high genetic diversity. In genetic distance-based cluster analysis, the populations of B. aeruginosa and B. dispiralis formed species-based clusters, whereas populations of B. angularia did 15202 Q.H.

These microsatellite loci should be useful for genetic diversity analysis, analysis of phylogenetic relationship, and species delimitation of Bellamya.

“…revealed that both groups consist not exclusively of in-lake endemics, as was formerly assumed, but of in-lake endemics sensu stricto plus one or two paludal/fluvial species endemic to the whole of the Malawi Basin, i.e., basin endemics (Sengupta et al, 2009;Schultheiß et al, 2009Schultheiß et al, , 2011. Both these Malawi species groups are monophyletic, young and the speciation processes still likely are going on in the viviparid flock (Schultheiß et al, 2011).…”

Lacustrine mollusc radiations in the Lake Malawi Basin: experiments in a natural laboratory for evolution

In terminal Pliocene–early Pleistocene times, part of the Malawi Basin was occupied by paleo-lake Chiwondo. Molluscan biostratigraphy situates this freshwater lake either in the East African wet phase between 2.7–2.4 Ma or that of 2.0–1.8 Ma. In-lake divergent evolution remained restricted to a few molluscan taxa and was very modest. The lacustrine Chiwondo fauna went extinct at the beginning of the Pleistocene. The modern Lake Malawi malacofauna is depauperate and descends from ubiquistic southeast African taxa and some Malawi basin endemics that invaded the present lake after the Late Pleistocene mega-droughts. The Pleistocene aridity crises caused dramatic changes, affecting the malacofauna of all East African lakes. All lacustrine endemic faunas that had evolved in the Pliocene rift lakes, such as paleo-lake Chiwondo, became extinct. In Lake Tanganyika, the freshwater ecosystem did not crash as in other lakes, but the environmental changes were sufficiently important to trigger a vast radiation. All African endemic lacustrine molluscan clades that are the result of in-lake divergence are hence geologically young, including the vast Lavigeria clade in Lake Tanganyika (ca. 43 species)
