| Popis: | The majority of management plans for birds on public lands across the western United States do not recognize the geographic variation in a given species’ habitat. We examined associations of plant species and functional groups with occupancy of 19 bird species across 5 biogeographic subregions of the Great Basin (central, western, Sierra Nevada, northern, and eastern), USA. We hypothesized that occupancy was associated with floristics (individual plant species) within subregions, and with physiognomy (characterized by functional groups) across the Great Basin. We used two methods to evaluate bird-vegetation associations within and across subregions. First, we examined which covariates of floristics and physiognomy were significantly associated with occupancy in each subregion. Second, for each bird species, we compared covariate estimates between each of the 10 pairs of subregions. We classified the effects of covariates on occupancy in 2 subregions as significantly different if |
