| non-monophyly and deep genetic differentiation across low-elevation barriers in a neotropical montane bird (basileuterus tristriatus; aves: parulidae). | most widespread birds of neotropical cloud forests exhibit phenotypic variation that is partitioned geographically suggesting allopatric divergence, but little is known about the extent to which such phenotypic differentiation is consistent with genetic variation. we studied geographic patterns of genetic differentiation in the three-striped warbler (basileuterus tristriatus), a polytypic and widespread understory bird of the foothills and mid-elevation zone of the tropical andes and adjacent mo ... | 2012 | 22484358 |
