Infanticide in microtines: Importance in natural populations

  • Rudy Boonstra


To test the hypothesis that the incidence of infanticide should increase as population density increases in microtines (Mallory and Brooks, 1978), an index of pregnancy success was developed. There was no negative correlation between population density and pregnancy success in four species of Microtus and thus the hypothesis is refuted. There was a positive correlation between instantaneous growth rate and pregnancy success in M. pennsylvanicus and M. townsendii.
