Does relaxed predation drive phenotypic divergence among insular populations?

Journal of evolutionary biology - 1 Aug 2014

Runemark A, Brydegaard M, Svensson E I

Abstract excerpt

The evolution of striking phenotypes on islands is a well-known phenomenon, and there has been a long-standing debate on the patterns of body size evolution on islands. The ecological causes driving divergence in insular populations are, however, poorly understood. Reduced predator fauna is expected to lower escape propensity, increase body size and relax selection for crypsis in small-bodied, insular prey...
