Résumé
The ecology and. distribution of each rodent sub species In northern Mohave County, with regard to Life Zone, plant associations and substrate, is the primary concern of this investigation, Oltellus leucurus escalante, Dlpodomys merrlaral merrlaml, and Castor canadensis ssp, are reported from the area for the first time. The ranges of Perognathus penicillatus sobrlnus. Pero gnathus formosus formosus. Pero^nathus lonpiimembrus arlzonensis, Onychomys leucogaster melanophrys. Peromyscus eremlcus eremicus, and Peromyscus boylil utahensls were found to be more extensive than previously reported. Local distribution of rodents is effected more by soil type than plant type. Also preference for a particular soil type appears to be a major factor in niche separation. The Grand Wash Cliffs and Virgin Mountains act as an isolating barrier and have functioned as a speciating mechanism within the area.
