Population Dynamics of Cotton Rats (Sigmodon hispidus) and Meadow Voles (Microtus pennsylvanicus ) in Field Enclosures in South Carolina

R. G. Weigert

 

Summary

Studies in one-acre field enclosures of the dynamics of separate populations in meadow voles (Microtus pennsylvanicus) and cotton rates (Sigmodon hispidus) as well as mixed populations of both species showed (1) that the former species is not excluded from the South Carolina coastal plain simply because of high summer temperatures; (2) that if the two species are capable of competitive exclusion, it does not seem to take the form of overt aggression; and (3) that in mixed populations of the two species there are no obvious behavioral mechanisms operating to partition the environment.
