abstract
The Wyoming pocket gopher (Thomomys clusius) is the only vertebrate species occurring exclusively in Wyoming. Sympatric with northern pocket gophers (Thomomys talpoides), T. clusius inhabits a much smaller range and differs in chromosome number. With increased natural resource extraction, and limited existing research, concern has grown regarding the Wyoming pocket gopher’s status. Gophers were trapped during the summer and fall across the historic range of T. clusius. Individuals caught were, however, morphologically more similar to T. t. ocius than to T. clusius. We used 367 (AFLP) markers to examine genetic variation in fifteen subspecies of T. talpoides throughout the Rocky Mountain region, including gophers captured in Southern Wyoming. Although previous studies based on mitochondrial and nuclear DNA revealed incomplete lineage sorting (poor resolution of phylogenetic differences) among species in the genus Thomomys, individuals from designated subspecies clustered monophyletically in our analyses (good phylogenetic resolution). Gophers captured in the historic range of T. clusius formed a monophyletic group most closely related to geographically the nearest subspecies of T. talpoides. These findings further suggest gophers captured in Wyoming were subspecies of T. talpoides and T. clusius is rare. Future work will include karyotype analysis of live trapped gophers, and DNA sequencing of short nuclear amplicons from 35 T. clusius museum along with other subspecies of T. talpoides in the hopes of identifying and characterizing genetic divergence in this potentially endangered pocket gopher. note
