Predator-driven phenotypic diversification in Gambusia affinis.

Evolution; international journal of organic evolution - 1 Oct 2004

Langerhans R Brian, Layman Craig A, Shokrollahi A Mona, DeWitt Thomas J

Abstract excerpt

Predation is heterogeneously distributed across space and time, and is presumed to represent a major source of evolutionary diversification. In fishes, fast-starts--sudden, high-energy swimming bursts--are often important in avoiding capture during a predator strike. Thus, in the presence of predators, we might expect evolution of morphological features that facilitate increased fast-start speed. We tested this...
