英文摘要 | In an earlier paper (Bowers et al. 1987) we reported patterns of microhabitat use by desert rodents among 0.25-ha plots where seeds were added or certain rodent species removed. We used the results to make inferences about the spatial organization of the whole rodent community. Here we change our focus to test for spatial usage patterns at a smaller (within-plot) scale. Specifically, we examine to what extent spatial use varies with proximity to mounded burrows of the large kangaroo rat, Dipodomys spectabilis. Capture frequency of five of nine rodent species was correlated with distance from D. spectabilis mounds, while six species showed correlations with vegetative cover that also increased with distance from mounds. In general, sites nearer mounds were underutilized, and sites further away overutilized by the rodent community as a whole. Logistic regression analyses showed for six species that vegetative cover and particularly, distance to nearest mound accounted for more of the variation in whether a station captured a species than did plot-to-plot (i.e., treatment) effects. Similar analyses using two plots where D. spectabilis was removed (where vacant mounds persisted for years) suggested that the selection of microhabitats with contrasting vegetation structure was more pronounced in the absence than in the presence of D. spectabilis, and that in most cases distance from mounds was important only if mounds were occupied. Spatial structure in this community appears to revolve around the occupation of space by dominant individuals that partially modify/obscure large scale patterns involving the selection of particular structural microhabitats. |
