Phylogeography of Keen's Mouse (Peromyscus keeni) in a Naturally Fragmented Landscape
Phylogenetic methods were used to analyze cytochrome- b sequences ( n = 257; 560 base pairs) from Peromyscus keeni (Keen's mouse) collected from 23 islands of the Alexander Archipelago and 6 mainland locations in southeast Alaska and western Canada. Although P. keeni is ubiquitous across this r...
