Trade-offs between predation risk and forage differ between migrant strategies in a migratory ungulate
Download2009
Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an \"escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous...

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...

Naturalization is a new and promising ecological approach to vegetation management for urban environments. Although there have been years of research focused on areas such as land reclamation, ecological restoration and plant establishment there is a lack of knowledge on how to reintegrate the...

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...

Vegetation responses following mountain pine beetle attack in lodgepole pine forests of west-central Alberta
DownloadFall 2018
Natural disturbances are an integral part of forest ecosystems and drive successional change. The boreal forest is adapted to stand-replacing fires, which have different ecological impacts than less severe disturbances, such as insect attacks. In recent years, mountain pine beetle (MPB), a bark...

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...

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...
