Abstract

Effects of patch size on animal densities and persistence rates in an old field in Kansas varied among animal species. The largest species, Sigmodon hispidus, was never found on the smallest patches, but densities of Reithrodontomys megalotis, Microtus ochrogaster, and Peromyscus maniculatus were often highest on the smallest patches. Animal density variations were often significantly explained by patch size using multiple regression analyses, but other, unmeasured, variables may have influenced results. Persistence rates of the three species were often highest on the largest patches. Animals visited small patches more often than large patches without staying, and used large patches to create territories. Small and medium patches may have been used as archipelagos of preferred habitat interspersed with less desirable habitat -from Authors
