摘要：of southern Utah. Specifically, we tested whether or not roads create adjacent zonescharacterized by lower small- mammal densities, abundance, and diversity. We sampled abundance ofsmall mammals at increasing distances from Interstate 15 during two summers. We recorded 11 generaand 13 species. We detected no clear abundance, density, or diversity effects relative to distance from theroad. Only two of 13 species were never captured near roads. The abundance of the remaining 11 smallmammal species was either similar at different distances from the road or higher closer to the road. Weconclude that although roads may act as barriers and possible sources of mortality, adjacent zones ofvegetation often provide favorable microhabitat in the desert landscape for many small mammals
