Reproductive Strategies of Meadow Voles, Hispid Cotton Rats, and Eastern Harvest Mice in Virginia
Patterns of reproduction in small mammals in Virginia were examined by autopsying samples of meadow voles (Microtus pennsylvanicus) collected for 23 months near Charlottesville, of hispid cotton rats (Sigmodon hispidus) collected for 14 months in Portsmouth, and by evaluating live-caught eastern har...
