Abstract
The author has made the analysis of musk deer population dynamics in the Jewish Autonomous region. The sexual structure, density limitation of juvenile survival and harvesting is taken into account by means of the proposed discrete-time model of population dynamics. The model parameters were estimated using an approach that accounts the total population size and allows the original structured model to be presented as a one-dimensional recurrent equation with a delay. It is carried out a comparison of demographic parameters estimates in the models of musk deer population dynamics, both with and without considering harvesting.
