Pleistocene glacial cycles and physical barriers influence phylogeographic structure in Black-capped chickadees (Poecile atricapillus), a widespread North American passerine
Accepted author manuscript The nonmigratory Black-capped Chickadee (Poecile atricapillus (Linnaeus, 1766)) has a continent-wide distribution extending across large parts of North America. To investigate the phylogeographic structure and verify possible refugia during the last glacial maximum, we seq...

To investigate the phylogeographic structure and verify possible refugia during the last glacial maximum, we sequenced a 678 bp region of the mitochondrial control region from 633 Black-capped Chickadees at 35 sites across North America and performed paleoecological distribution modeling.

The Newfoundland population has remained isolated from continental populations for at least 65 000 years and contains a number of fixed nucleotide differences.

Paleoecological distribution modeling predicted suitable habitat in Alaska, off the coast of Newfoundland, and several locations across the southern United States during the last glacial maximum, whereas suitable habitat during the last interglacial was more similar to the contemporary distribution.
