Forest rodents serve two potential roles for plants
Seed dispersal through caching Seed predation
Many species eat seeds Potential for evolutionary responses
Size assortment Masting
Previous studies of closely related seed predators
Species are not always redundant Peromyscus: difference in foraging
preferences for maple seeds
Community Effects
Important members of forest communities
Prey for carnivorous species Dual role for many tree species
