Abstract
In the paper, the authors analyze dynamics of the ungulates inhabiting the Jewish Autonomous region. They use a discrete-time model of a sex-structured population with density-dependent limitation of juvenile survival. Model parameters are estimated based on an approach that accounts the total population size and allows presentation of the structured model as a one-dimensional recurrent delayed equation. The results obtained show that population sizes of elk, red deer, roe deer, and musk deer demonstrate stable dynamics.
