Differentiation with drift: a spatio-temporal genetic analysis of Galapagos mockingbird populations (Mimus spp.).

Philosophical transactions of the Royal Society of London. Series B, Biological sciences - 12 Apr 2010

Abstract excerpt

Small and isolated island populations provide ideal systems to study the effects of limited population size, genetic drift and gene flow on genetic diversity. We assessed genetic diversity within and differentiation among 19 mockingbird populations on 15 Galápagos islands, covering all four endemic species, using 16 microsatellite loci. We tested for signs of drift and gene flow, and used historic specimens to...
