Habitat selection and ecological speciation in Galápagos warbler finches (Certhidea olivacea and Certhidea fusca).

Proceedings. Biological sciences - 22 Apr 2005

Tonnis Brandon, Grant Peter R, Grant B Rosemary, Petren Kenneth

Abstract excerpt

We investigated phylogeographic divergence among populations of Galápagos warble finches. Their broad distribution, lack of phenotypic differentiation and low levels of genetic divergence make warbler finches an appropriate model to study speciation in allopatry. A positive relationship between genetic and geographical distance is expected for island taxa. Warbler finches actually showed a negative isolation by...
