Population biology, genetic structure, and mating system parameters in freshwater snailsal examples from our population biological studies on tropical species in the planorbid . and the European stream limpet, . These ongoing studies contribute to a deeper understanding of the evolution of selfing versus outcrossing.

Evolution and ecological correlates of uniparental and biparental reproduction in freshwater snailsg trematode that may prevent cross-fertilization; these patterns suggest that parthenogenesis has been selected as a mechanism to assure reproduction. We also discuss the taxonomic distribution of parthenogenesis in aquatic invertebrates, and suggest that brooding may be an exaptation for the evolut

Evolutionary consequences of postglacial colonization of fresh water by primitively anadromous fishees also diversify. Lake fish often specialize for use of either plankton or benthic prey, and it sometimes results in formation of species pairs or trophic polymorphism. Loss of parasitism is a special feature of lamprey radiation, and diversification of bony armor phenotypes is peculiar to stickleb

If predators induce increases in prey dispersal rates then local prey density will decline. In contrast, if predators suppress prey dispersal rates then this will t
