Perognathus fasciatus (olive-backed pocket mouse) in Wyoming. About 30% of the individuals I caught at this locality had that cool little white spot on their head.

Dipodomys ordii (Ord's Kangaroo rat)

Research Interests: I am primarily interested in the evolution of geographic diversity of arid adapted mammals. I am currently studying the phylogeography of the Perognathus flavus and Perognathus fasciatus species groups using mitochondrial and nuclear data. These two groups range from Central Mexico north into Canada and generally occur on sandy arid grassland and scrub habitats. My dissertation involves using comparative phylogeographic approaches to examine the temporal and spatial congruence of molecular divergence within several Heteromyid species – Perognathus flavus and fasciatus species groups already mentioned and Dipodomys ordii a kangaroo rat that shares the composite distribution of the two Perognathus groups. The ultimate goal of which is to develop a general hypothesis for the evolution of arid grassland and shrubland ecosystems

Things to do in Las Vegas:

Numerous public lands for hiking,
climbing, camping. Lake Mead.
The live music scene is not
great, there are some local gems
but they're hard to find.
Pretty good stand up comedy.
