摘要:Subspecies, or geographic races, are diagnosable populations that, at least during the breeding season, are largely allopatric with other subspecies of the same species. In attempts to give objectivity to the subspecies concept, arbitrary rules have been applied for the recogniti...

摘要:We surveyed the permanent-resident bird community of a fragmented Ohio landscape for West Nile virus (WNV) antibodies to determine which species carried antibodies, what percentage of the individuals in each species carried antibodies, and whether antibodies were retained from on...
