Brown bear body mass and growth in northern and southern Europe

We tested six hypotheses to explain expected geographical differences in body masses of 1, 771 brown bears (Ursus arctos) from northern and southern Europe (Sweden and Norway compared with Slovenia and Croatia): Bergmann’ s rule, the fasting endurance hypothesis, and the dietary meat hypothesis, which predicted larger bears in the north ; and hypotheses stressing the role of high primary productivity, high population density, low seasonality, and length of the growing season, which predicted larger bears in the south. Although brown bear populations in North
