Abstract

Mountain Chickadees (Parus gambeli) were collected from mountain ranges of the Great Basin and surrounding areas. Restriction endonuclease digestion of their mitochondrial DNA revealed two highly distinct haplotypes. One of these occurred in the Great Basin and extended eastward into Arizona and the Rocky Mountains of Utah. The other occurred in locations west of the Great Basin, including the Sierra-Nevada Mountains and southern California. Patterns of divergence were not wholly consistent with the subspecific taxonomy. The magnitude of genetic differentiation between haplotypes was larger than what is commonly reported for avian populations. The geographic partitioning of haplotypes may be a result of the topography of the western United States and is supportive of models of paleobiogeography in the Great Basin.
