Influence of wolf predation on population momentum of the Nushagak Peninsula caribou herd, southwestern Alaska
We investigated wolf predation as a potential driver of population change in the Nushagak Peninsula caribou herd, southwestern Alaska. We investigated the time budgets of three wolf packs using the peninsula from 2007 through 2012, and thus potentially preying on caribou there, in order to make infe...
