Camouflaged or tanned: plasticity in freshwater snail pigmentation [PDF]
Biology Letters, 2013 By having phenotypically plastic traits, many organisms optimize their fitness in response to fluctuating threats. Freshwater snails with translucent shells, e.g. snails from the Radix genus, differ considerably in their mantle pigmentation patterns, with snails from the same water body ranging from being completely

Molecular Evolution of Freshwater Snails with Contrasting Mating Systems [PDF]
Molecular Biology and Evolution, 2015 Because mating systems affect population genetics and ecology, they are expected to impact the molecular evolution of species. Self-fertilizing species experience reduced effective population size, recombination rates, and heterozygosity, which in turn should decrease the efficacy of natural selection, both adaptive and purifying, and the strength of ...

Phylogeny of freshwater viviparid snails in Japan [PDF]
Journal of Molluscan Studies, 2015 We document extensive incongruence between molecular phylogeny and the current taxonomy of the freshwater gastropod family Viviparidae in Japan. A phylogeny based on the mitochondrial cytochrome oxidase subunit I and 16S rRNA genes for East Asian viviparids comprises three major clades, the two largest of which are composed primarily of paraphyletic or
