What is Microhabitat selection by two rodent species in the cerrado of Central Brazil about?
We examined differences in microhabitat utilization by two sympatric rodents in the Brazilian cerrado (tropical savanna). We censused the populations by livetrapping techniques in March and May 1984, and simultaneously we measured a set of eight microhabitat variables. Patterns of habitat utilization and species relationships were examined with t tests, Mann Whitney-U tests and regression analysis. The two species differed markedly in three microhabitat variables : plant species richness (PSR), forb ground cover (FGC) and distance to nearest tree or shrub (DTS). Bolomys lasiurus was a generalist associated with high richness and high cover of forbs, shrubs and trees. Oxymycterus roberti was associated with a less diverse lower forb, shrub, tree cover and higher grass ground cover (GGC). Regression analysis showed that the most important estimator of Bolomys lasiurus abundance was GGC and tree and shrub cover TSC. For Oxymycterus roberti, FGC, PSR and TSC. The differences in microhabitat variables between these two species, could be related to foraging mode and/or predation avoidance.
