Abstract

The Wupatki pocket mouse (Perognathus amplus cineris), a subspecies of the Arizona pocket mouse, is a species of concern i the Arizona Heritage Data Management System and a Group 4 species on the Navajo Endangered Species list, but the limits of its geographical range and vegetation associations are poorly known. We analyzed data collected between 2002 and 2004 and conducted live-trapping surveys at 32 sites in and around Wupatki National Monument during the summer, 2011, to determine ho this subspecies’ distribution was related to elevation, land use, and dominant vegetation type. We also resampled a subset of sites in the fall, 2011, to test whether the abundance of the Wupatki pocket mouse declined as would be expected if this subspecies was sensitive to temperature changes and entered a period of lessened activity during winter. Our analyses indicated the Wupatki pocket mouse was most abundant between 1,450 and 1,600 m and was more abundant inside th monument than outside where livestock grazing was permitted. It was more strongly associated with the black grama vegetation type and less associated with galleta grassland, juniper scrub, and saltbush vegetation types. These data suggest that models predicting future distribution of this subspecies under climate change should include interactions with human land use and climate effects on vegetation and temperature.
