Evidence for negative frequency-dependent selection during experimental coevolution of a freshwater snail and a sterilizing trematode.

Evolution; international journal of organic evolution - 1 Sept 2009

Koskella Britt, Lively Curtis M

Abstract excerpt

Host-parasite coevolution is often suggested as a mechanism for maintaining genetic diversity, but finding direct evidence has proven difficult. In the present study, we examine the process of coevolution using a freshwater New Zealand snail (Potamopyrgus antipodarum) and its common parasite (the sterilizing trematode, Microphallus sp.) Specifically, we test for changes in genotypic composition of clonal host...
