| population structure and plumage polymorphism: the intraspecific evolutionary relationships of a polymorphic raptor, buteo jamaicensis harlani. | phenotypic and molecular genetic data often provide conflicting patterns of intraspecific relationships confounding phylogenetic inference, particularly among birds where a variety of environmental factors may influence plumage characters. among diurnal raptors, the taxonomic relationship of buteo jamaicensis harlani to other b. jamaicensis subspecies has been long debated because of the polytypic nature of the plumage characteristics used in subspecies or species designations. | 2010 | 20650000 |
