Trees Wanted - dead or alive! Host selection and population dynamics in tree-killing bark beetles
Download2011
Erbilgin, N., Gregoire, J. C., Gilbert, M., Kausrud, K. L., Skarpaas, O., Stenseth, N. C., Okland, B.
Abstract: Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing...

Triage for conserving populations of threatened species: The case of woodland caribou in Alberta.
Download2010
Hauer, G., Adarnowicz, W., Boutin, S., Schneider, R.
Prioritization of conservation efforts for threatened and endangered species has tended to focus on factors measuring the risk of extirpation rather than the probability of success and cost. Approaches such as triage are advisable when three main conditions are present: insufficient capacity...

Historically seismic data processing has relied on the acoustic approximation to process single component data under the simplifying assumption that the recorded wavefield consists mainly of compressional wave modes. With the advancement of multicomponent seismic technology there is an increased...

Venison to beef and deviance from truth: biotelemetry for detecting seasonal wolf prey selection in Alberta
DownloadFall 2010
An abrupt interface between mountains and prairies in southwestern Alberta means wilderness areas and carnivore populations overlap cattle grazing lands. Consequently, there is concern about the effects of large carnivores, especially wolves, on livestock. I used GPS clusters and scat samples...

Doctoral thesis. An investigation of the effects of wage employment on Inuit from Pond Inlet and Arctic Bay. Specifically focuses on two questions: 1) how are Inuit workers reacting to on-the-job demands of their oil exploration wage employment? and 2) what effect is the massive influx of wage...

Wolf Reproduction in Response to Caribou Migration and Industrial Development on the Central Barrens of Mainland Canada
Download2008
Cluff, H.D., Frame, P.F., Hik, D.S.
Reproductive success of mammals is greatly influenced by food availability. Where wolves (Canis lupus) prey on migratory barren-ground caribou (Rangifer tarandus), caribou migration patterns strongly influence food availability for wolves. However, industrial development in formerly undeveloped...

Wolves Influence Elk Movements: Behavior Shapes a Trophic Cascade in Yellowstone National Park
Download2005
Fortin, D., Beyer, H. L., Smith, D. W., Boyce, M. S., Mao, J. S., Duchesne, T.
A trophic cascade recently has been reported among wolves, elk, and aspen on the northern winter range of Yellowstone National Park, Wyoming, USA, but the mechanisms of indirect interactions within this food chain have yet to be established. We investigated whether the observed trophic cascade...
