This chapter examines the impact of climate change on the distribution of two species of woodland mouse deer, Peromyscus maniculatus gracilis and Peromyscus leucopus, in Michigan. It explains that the relative abundance of gracilis in this area has declined from over forty percent before 1931 to around six percent in 2003. The chapter suggests that the population of leucopus is related to the length of the winter because few leucopus survive long winters. It concludes that the recent tendency for winters to end early may be responsible for the decline in gracilis populations.
