Discrete-Time Model of an Exploited Population with Age and Sex Structures: Instability and the Hydra Effect

Discrete-Time Model of an Exploited Population with Age and Sex Structures: Instability and the Hydra Effect

This study proposes a discrete-time mathematical model to investigate the impact of selective harvesting on the dynamics of a population with age and sex structures. The model assumes that the birth rate depends on the sex ratio of the population and the number of breeding pairs. The growth rate is...
