Extinguishing A Learned Response In A Free-Ranging Gray Wolf (Canis Lupus), L. David Mech
Extinguishing A Learned Response In A Free-Ranging Gray Wolf (Canis Lupus), L. David Mech
USGS Northern Prairie Wildlife Research Center
Learning and extinguishing learned behaviour (Thorn dike 1911; Skinner 1953) have been well studied in domestic dogs (Miklosi 2015). Some investigations of learning have been conducted with captive Gray Wolves (Canis lupus; Packard 2003; Frank 2011), including one study that included extinguishing learned behaviour (Cheney 1982). In addition, considerable research has been done comparing social learning be - tween dogs and captive wolves (Range and Viranyi 2013; Marshall-Pescini et al. 2015). However, to my knowledge, only Packard (2012) has studied learning in free-ranging wolves, and no one has investigated extinguishing a learned response in such wolves. The purpose of this …

Aggression directed at conspecific groups is common among gregarious, territorial species, and for some species such as gray wolves (Canis lupus) intraspecific strife is the leading cause of natural mortality. Each individual in a group likely has different measures of the costs and benefits associated with a group task, such as an aggressive attack on another group, which can alter motivation and behavior. We observed 292 inter-pack aggressive interactions in Yellowstone National Park between 1 April 1995 and 1 April 2011 (>5300 days of observation) in order to determine the role of both sexes, and the influence of pack, …
