Abstract
Effective population size (Ne) and generation interval as affected by various hunting policies for moose and white-tailed deer was estimated using stochastic computer simulations. Both parameters, and particularly the generation interval, can vary drastically for different hunting regimes. For the various regimes simulated for the moose, the generation intervals ranged from 4.2-9.9 yr and the ratios of effective population size to actual population size from approximately 0.2-0.4. The amount of genic variation can be severely reduced even within short periods of time as a result of improper management policies.
