Great Basin Naturalist


Studies of microhabitat of 14 species of rodents by cluster analysis suggested that the diverse landscapes of Canyonlands National Park, Utah, include six broad "habitat-types": (1) rimrock; (2) desert shrublands; (3) saxicoline woodland and sagebrush; (4) oakbrush; (5) riparian deciduous woodland; and (6) grasslands. Perognathus parvus and Neotoma cinerea were the species most strongly associated with single "habitat-types," desert shrub and saxicoline woodland, respectively. Peromyscus maniculatus and P. truei were the species associated with the broadest ranges of habitats. The rodents with the most similar habitats were Neotoma mexicana and Peromyscus boylii; Eutamias quadrivittatus, P. truei, and P. crinitus; Ammospermophilus leucurus and P. maniculatus; and Dipodomys ordii and Onychomys leucogaster.
