Authors analysed 527 fecal samples of the brown bears inhabiting boreal forest of southcentral Sweden, collected in 1994-1996 and 2000-2001. They described seasonal and annual variation in the diet of brown bears, they also studied berry availability by inventorying 308 random plots. Authors suggest that the effects of predicted future climatic change might have severe effects on the availability of the berries, which is the only important food available for fat acquisition prior to hibernation.
