Effects of cropping practices and phenological changes in crop vegetation on small mammal abundance were examined. Twelve 0.4-ha experimental plots planted in either soybean-sorghum strip-crops (N = 8) or soybean monocultures (N = 4) were live-trapped from 5 April-13 December 1993. Mean abundance of deer mice (Peromyscus maniculatus) differed significantly between monoculture and strip-cropped treatments during mid-November and mid-December. Extensive movements by deer mice between plots suggest that this species increased its scale of movement in agroecosystems compared to other habitat types. Invasion of house mice (Mus musculus) during early August was influenced by the interaction of phenological changes in vegetation and strip-cropping. Meadow voles (Microtus pennsylvanicus) were more abundant in grain-crop agroecosystems than previously reported.
