    Microhabitat Separation and Coexistence of Two Temperate-zone Rodents
    (1984) Douglas W. Morris
    Microhabitat separation of White-footed Mice (Peromyscus leucopus) and Meadow Voles (Microtus pennsylvanicus) was analyzed within two macrohabitats in Point Pelee National Park. Foliage height diversity, an important predicior of habitat separation by Mice and Voles in macrohabitat studies, was unimportant when the separation was analyzed within habitats. Significant microhabitat separation between White-footed Mice and Meadow Voles reflected macrohabitat preferences, but the separation was dynamic, and no single variable consistently accounted for microhabitat differences. The coexistence of Mice and Voles appears to depend upon microhabitat differences which are maintained despite frequent shifts in microhabitat use by each species.
