Ecology of wolves in relation to a migratory carbiou herd in northwest Alaska
Article Abstract:
There is a lack of data relating to wolf demography, predation and movement patterns in relation migratory caribou. A study of wolves and the Western Arctic Caribou Herd in northwestern Alaska, using radio collars, found that after relocation, the wolf packs maintained year round resident territories, and did not follow migratory caribou. However up to 17% of the marked wolf packs follow migratory caribou when caribou were absent and there was a low density of moose, returning to original territories for denning. Wolf densities were restricted by hunting and trapping and caribou population growth was not strongly limited by wolf predation levels.

Modeling the western Arctic caribou herd during a positive growth phase: Potential effects of wolves and radiocollars
Article Abstract:
Wolf predation was found to be an effective tool for control of Arctic caribou population in Alaska, USA, but effective control of caribou population depended on wolf densities. Radiocollars had negative effect on vital rates of female and calves and survival data from radiocollared females and calves failed to predict growth of Western Arctic caribou herd.
