Annual and superpopulation abundances for western Hudson Bay (WHB) polar bears from Jolly-Seber models that ignore age structure (black) or incorporate age structure and assume annual survival is constant (blue) or a quadratic function of age (red).

Points and error bars are posterior medians and 95% credible intervals, respectively. Analyses used a subset of the larger, long-term WHB polar bear study and, therefore, do not reflect the status of the entire subpopulation ([ 28 ]; see Methods for additional details).
