Research paper thumbnail of Vegetative and edaphic factors affecting abundance and distribution of small mammals in southeast Oregon

The Great Basin naturalist, 1979

The relationships between vegetative and edaphic habitat factors and the local distribution and a... more The relationships between vegetative and edaphic habitat factors and the local distribution and abundance of small mammals on Malheur National Wildlife Refuge, Harney County, Oregon, were examined between July 1973 and June 1975. Of 16 species of small mammals captured, deer mice {Peromyscus maniculatus), montane voles {Microttts montanus). Great Basin pocket mice {Perognathus parvus), and least chipmunks {Eutamias minimus) comprised 90.1 percent of the individuals. The physiognomy of the vegetation was a factor in the distribution of rodent species other than deer mice. Pocket mice and chipmunks were restricted to the communities dominated by sagebrush (Artemisia tridentata) or greasewood (Sarcobatus vermiculatus). Population densities of pocket mice and chipmunks were significantly related to edaphic factors such as soil depth, texture, and strength, which may have affected the construction and stability of burrows. Montane voles occurred only in marsh or grassland communities. Population densities of voles were directly correlated with the amount of cover and inversely correlated with its patchiness. Deer mice were the most common species encountered and occurred in all but the grassland communities. The density of this species was related to vegetative or edaphic factors only seasonally or in certain habitats, and few generalizations could be made.

Of 57 loci examined, 18 were polymorphic. Patterns of frequency distribution of alleles at polymorphic loci indicate considerable genetic heterogeneity within deer from western Maryland; differentiation of deer populations was observed over short geographical distances. The genetic character of the deer of western Maryland is thought to be strongly influenced by natural selection, genetic drift, and the hunting regime. The white-tailed deer (Odocoileus virginianus) is easily the most popular, far-ranging, and economically important big game animal in North America. Yet deer were on the verge of extirpation in Maryland as well as most other eastern states in the early 1900's due mainly to unrestricted hunting pressures. Through protective legislation, public awareness and support, land prote...
