Data from: Reproductive isolation and cryptic introgression in a sky island enclave of Appalachian birds

Brian S. Davidson, Gene D. Sattler, Sara Via & Michael J. Braun
Reproductive isolation is central to the speciation process, and cases where the strength of reproductive isolation varies geographically can inform our understanding of speciation mechanisms. Although generally treated as separate species, Black-capped chickadees (Poecile atricapillus) and Carolina chickadees (P. carolinensis) hybridize and undergo genetic introgression in many areas where they come into contact across the eastern United States and in the northern Appalachian Mountains. The Great Smoky Mountains harbor the last large breeding population of...
