Linzey, A., G. Hammerson. Encroaching woody vegetation can decrease grassland small mammal diversity; and the likelihood of prairie vole presence decreases as woody vegetation increases (Matlack et al. Transgenic mice were created that had a prairie vole V1a receptor promoter region inserted, and these mice subsequently expressed V1a receptors in a distribution pattern similar to that of prairie voles. 2008). The prairie vole (Microtus ochrogaster) and woodland vole (M. pinetorum) are found statewide. Additional Information: This grassland rodent shares habitat with the Meadow Vole, but is decidedly less common. Food: Grass, green vegetation, roots, and other plant material is the primary food. 2.
