Note. – Linear regression coefficients and standard errors (SE) for each species when small-mammal abundance is calculated as a function of the percentage of cheatgrass cover for sites in the Great Basin Desert, Utah (data collected 2011–2012). The asterisk denotes significance at the P<0.05 level.
