Interspecific and intraspecific social interactions among brown bears and wolves in an enclosure

摘要: We investigated bear-bear, wolf-wolf, and bear-wolf interactions in a 2-ha enclosure, which was occupied by 13 brown bears (Ursus arctos) wolf (Canis lupus) pack. The hierarchy of wolves determined behavioral observation rank order analysis. All between were systematically videotaped for 1 month analyzed. Bears had hierarchical organization similar to that found nature, although we relatively low position the blind bears. Social appeared be very serious at times. Bear-wolf mostly playful, but sometimes agonistic. Young more often victims harassment than other seriously bitten. However, no deaths recorded, contrary descriptions from natural interactions. concluded could kept safely together single enclosure with apparently few consequences. Interactions observed comparable under conditions concerned mainly competition over food or den (wolf bear). size (large prey carcasses wild vs. chicken enclosure) probably plays role severity eventual solution conflict.
