Description

Abstract. -- The rodent assemblages in prairie dominated by native grasses and in prairie dominated by the exotic King Ranch bluestem (Bothriochloa ischaemum) in central Texas were compared to determine if non-native prairie supported a less species-rich rodent fauna than native prairie. Species richness was greatest in the native Muhlenbergia habitat (three species) and least in the non-native King Ranch bluestem habitat (one species). Densities of the hispid cotton rat (Sigmodon hispidus) were significantly greater in the Muhlenbergia habitat than in King Ranch bluestem. Relative abundance of S. hispidus correlated significantly with cover provided by dead material, Muhlenbergia, and by "other grasses" comprising a relatively small proportion of the prairie flora. **********
