Quantity Discrimination in Wolves (Canis lupus)
Quantity discrimination has been studied extensively in different non-human animal species. In the current study, we tested 11 hand-raised wolves (Canis lupus) in a two-way choice task. We placed a number of food items (one to four) sequentially into two opaque cans and asked the wolves to choose the larger amount. Moreover, we conducted two additional control conditions to rule out non-numeric...

The ability to coordinate with others' head and eye orientation to look in the same direction is considered a key step towards an understanding of others mental states like attention and intention.

Wolves contribute to regulating prey-predator dynamics and interact with human activities, mainly livestock farming and ungulate hunting.

متن کاملDiazepam-induced feeding in captive gray wolves (Canis lupus).
Diazepam doses of 0.2, 0.4, and 0.8 mg/kg induced feeding in sated gray wolves in a dose-dependent manner (p less than 0.001). Neither 0.8 mg/kg of the benzodiazepine antagonist, beta-CCP (p = 0.36), nor 0.8 mg/kg of the benzodiazepine inverse agonist, beta-CCE (p = 0.85), decreased the diazepam-induced hyperphagia. Five of 6 naive wolves (p = 0.003) ate dry dog food within 15.4 +/- 1.9 min of ...
