Great Basin Naturalist


During studies of ectoparasites in 12 plant communities in 1966 and 1967, five types of traps were used to capture 2,478 mammals of the following 11 species: Dipodomys ordii, Eutamias minimus, Microtus montanus, Onychomys leucogaster, Perognathus parvus, Peromyscus maniculatus, Reithrodontomys megalotis, Sorex merriami, Spermophilus townsendii, Neotoma cinerea, and Thomomys talpoides. The most abundant species was D. ordii and the least, M. montanus. Plant communities which contained the greatest number of species were the Chrysothamnus-Artemisia and Chrysothamnus-grass-Tetradymia. Fewest species were found in the grass and Juniperus communities. Greatest populations were in the Juniperus and grass communities, and lowest populations in the Artemisia-Chrysothamnus, Artemisia-Atriplex, and Chrysothamnus-grass-Tetradymia associations.
