Abstract:According to models of ecological speciation, adaptation to adjacent, contrasting habitat types can lead to population divergence given strong enough environment‐driven selection to counteract the homogenizing effect of gene flow. We tested this hypothesis in the common chaffinch (Fringilla coelebs) on the small island of La Palma, Canary Islands, where it occupies two markedly different habitats. Isotopic (δ13C, δ15N) analysis of feathers indicated that birds in the two habitats differed in ecosystem and/or d… Show more
