From the Abstract: "The postglacial recolonization of northern North America was heavily influenced by the Pleistocene glaciation. In the Pacific Northwest, there were two distince regions of mesic temperate forest, one coastal and the other interior. The chestnut-backed chickadee is one of the species associated with this distinctive ecosystem. using seven microsatellite markers we found evidence of population structure among nine populations of chestnut-backed chackadees. High levels of allelic variation were found in each of the populations. ... The pattern of population structure among contemporary chickadee populations is consistent with a pioneeer model of recolonization. The persistence of genetic structure in western North America chestnut-backed chickadees mary be aided by their sedentary behavior, linear distribution, and dependence on cedar-hemnoock forests."
