Population Size, Generation Interval, and Potential Loss of Genetic Variability
in Game Species under Different Hunting Regimes
Ryman, Ramone Baccus, Christina Reuterwall and Michael H. Smith
Effective population sizes (Na) and
generation intervals 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 to 9.9 yr and the ratios of effective population size to actual
population size from approximately 0.2 to 0.4.
It is concluded that the amount of genic variation can be severely
reduced even within short periods of times as a result of improper management
