| coalescent models reveal the relative roles of ancestral polymorphism, vicariance, and dispersal in shaping phylogeographical structure of an african montane forest robin. | although many studies have documented the effect of glaciation on the evolutionary history of northern hemisphere flora and fauna, this study is the first to investigate how the indirect aridification of africa caused by global cooling in response to glacial cycles at higher latitudes has influenced the evolutionary history of an african montane bird. mitochondrial dna sequences from the nadh 3 gene were collected from 283 individual starred robins (pogonocichla stellata, muscicapoidea). at leas ... | 2006 | 16024259 |
| genetic equilibrium despite habitat fragmentation in an afrotropical bird. | we examined the effects of habitat fragmentation of the white-starred robin pogonocichla stellata metapopulation in the taita hills archipelago, a hotspot for biodiversity which was fragmented approximately 40 years ago. using seven microsatellite markers, we analysed the robin's genetic structure and tested for equilibrium between migration and drift (testing the probability of decreased dispersal) as well as between mutation and drift (test for recent reduction in effective population size, i. ... | 2004 | 15140086 |
