Abstract

Even highly mobile species like birds can fail to disperse across fragmented landscapes. Within the naturally fragmented forests of the northern Great Basin, unique species such as the South Hills Crossbill, have evolved in isolation, and other species there may exhibit unique genetic diversity. Because the Northern Goshawk has shown low integration between geographically dispersed populations elsewhere in its range, we compared microsatellite loci and mitochondrial DNA sequences among individuals in five forest islands in south-central Idaho to search for signs of historical isolation. Our work provides a foundation for understanding the genetic ecology of goshawks in the Great Basin.
