Fewer mammalian species occurred on summits of sheer-walled buttes than occurred in similar "mainland" control sites, but density of small mammals on buttes equaled or exceeded mainland density. Peromyscus crinitus, the only terrestrial mammal on Jug Butte, occupied a larger habitat niche there than in control areas. No such niche expansion was noted for P. crinitus on Junction Butte, where four other species of small mammals (Eutamias quadrivittatus, Neotoma lepida, Neotoma cinerea, Peromyscus truei) and at least one large mammal (Canis latrans) also occurred. At least 18 species of terrestrial mammals inhabit the control sites. It is hypothesized that the species number remains static on each butte and is a function...
