Disruptive selection in a bimodal population of Darwin's finches.

Proceedings. Biological sciences - 22 Feb 2009

Hendry Andrew P, Huber Sarah K, De León Luis F, Herrel Anthony, Podos Jeffrey

Abstract excerpt

A key part of the ecological theory of adaptive radiation is disruptive selection during periods of sympatry. Some insight into this process might be gained by studying populations that are bimodal for dual-context traits, i.e. those showing adaptive divergence and also contributing to reproductive isolation. A population meeting these criteria is the medium ground finch (Geospiza fortis) of El Garrapatero, Santa...
