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...
متن کاملGenetics and conservation of wolves Canis lupus in Europe
The wolf Canis lupus, the most widespread of the four species of large carnivores in Europe, after centuries of population decline and eradication, is now recovering in many countries. Wolves contribute to regulating prey-predator dynamics and interact with human activities, mainly livestock farming and ungulate hunting. Although wolves are protected in most European countries, illegal or incid...
متن کاملDevelopment of Gaze Following Abilities in Wolves (Canis Lupus)
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. Here, we investigated the ontogeny and habituation patterns of gaze following into distant space and behind barriers in nine hand-raised wolves. We found that these wolves could use conspecific as we...
متن کاملWhere and How Wolves (Canis lupus) Kill Beavers (Castor canadensis)
Beavers (Castor canadensis) can be a significant prey item for wolves (Canis lupus) in boreal ecosystems due to their abundance and vulnerability on land. How wolves hunt beavers in these systems is largely unknown, however, because observing predation is challenging. We inferred how wolves hunt beavers by identifying kill sites using clusters of locations from GPS-collared wolves in Voyageurs ...
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 ...
