Using a long-term study (>30 years) on Scandinavian brown bears (Ursus arctos), I study the causes of variation in the duration of maternal care in this wild carnivore. I evaluate factors linked with maternal characteristics, but also consider the potential effect of the high hunting pressure applied on this population. Indeed, family groups (females with dependent offspring) are provided legal protection from hunting, which may cause artificial selection for a lengthening of the duration of maternal care. Because such phenotypic change would lead to a reduction in female fecundity, I am also interested in evaluating the demographic consequences of variations in the duration of maternal care.
