Annual age structure of western Hudson Bay polar bears using an age-structured Jolly-Seber model that assumes annual survival is a quadratic function of age (black; medians and 95% credible intervals).

Red points are year-specific proportions from observed data. Grey polygon denotes prime breeding ages (10–15 years of age). The annual proportion of the population in prime breeding age is summarized in lower right panel (median and 95% credible intervals).
