Landscape Genetic Assessment of Gunnison Sage-grouse

The range of the Gunnison Sage-grouse has been fragmented into geographically and genetically distinct populations. The viability of the individual populations and long-term persistence of the species may be impacted by the ability of individual birds to move between populations. We are using genetic samples to infer connectivity across the species range and between leks within the Gunnison Basin to gain insight on which landscape or habitat features are contributing to the fragmentation of the species range. Our connectivity analysis within the basin will provide insight at a manageable scale and ultimately aims to inform current and future management possibilities by delineating corridors of movement and barriers to movement.

Mountain Plover (Charadrius montanus) is a species of conservation concern that has experienced significant habitat loss and population decline. This, coupled with previous observations that the species exhibits strong fidelity to breeding grounds, suggests that breeding populations may be genetically differentiated and possibly suffer from reduced genetic variation associated with relatively small population sizes…

Cumulative loss of habitat and long-term decline in the population of the Lesser Prairie-Chicken (Tympanuchus pallidicinctus) have led to concerns for the species’ viability throughout its range in the southern Great Plains. For more efficient conservation past and present distributions of genetic variation need to be understood. We examined the distribution of mitochondrial DNA (mtDNA) variation in the Lesser Prairie-Chicken across Kansas, Colorado, Oklahoma, and New Mexico...
