The purpose of this study was to examine some of the possible causes for the negative density-area relationship reported for the white-footed mouse, Peromyscus leucopus. I examined predation and food availability in three small and three large forest fragments. Giving up density trays and various odors were used to test the variation in foraging behavior in the presence of a predator odor. Nest boxes and counts of periodical cicada emergence holes were used to test the effects of an emergence of periodical cicadas on P. leucopus population densities. Predator odors had no effect on foraging behaviors. P. leucopus responded to indirect, but not direct, cues of predation. Estimated densities of periodical cicada emergence holes were strongly related to the relative population density of P. leucopus. Continued study of predation and food differences in forest fragments of different sizes is needed to further examine the negative density-area relationship of P. leucopus.

"Rodents often play vital roles in their ecosystems as seed predators and dispersers and can significantly influence the succession and assembly of plant communities. We conducted seed tray experiments to assess the nutritional and environmental factors that influence selection and foraging time of three common rodent granivores: the white-footed mouse (Peromyscus leucopus), the deer mouse (Peromyscus maniculatus), and the southern red-backed vole (Myodes gapperi) for three common seeds: American beech (Fagus grandifolia), red maple (Acer rubrum), and eastern hemlock (Tsuga canadensis). This work was conducted at Bartlett Experimental Forest located within White Mountain National Forest in New Hampshire ... Our results illustrate the complexity of rodent foraging behaviors and decisions, with selections being driven by many factors. The most important of these factors is seed quality, though this can be influenced by other factors such as seed availability and environmental changes. These findings contribute to our understanding of rodent foraging patterns and underscore the importance of identifying factors influencing these patterns"--Page ix.
