Small Mammal Ecology and Behavior
Michael J. Cramer

Research Interests:

My research is based in the ecology and behavior of small mammals, especially deer mice (genus Peromyscus), and I am keenly interested in the differences between the white-footed deer mouse (Peromyscus leucopus) and the woodland deer mouse (Peromyscus maniculatus gracilis). My master’s work in Texas addressed the impact of habitat heterogeneity on a semi-arid small mammal community, and my dissertation work investigated the effects of a common parasite (bot fly) on the reproductive behavior of white-footed deer mice. Currently, I study the foraging ecology of seed predators, especially deer mice and chipmunks. I am also interested in how mice, which are common prey for a variety of predators, alter their foraging behavior in the presence of predators. Finally, I am interested in parasite-host relationships, especially those between small mammals and ectoparasites, such as ticks, which are vectors for a variety of diseases.
