The Role of Nutrient and Carbon Reserve Status of Aspen Seedlings in Root-Soil Interactions
DownloadFall 2015
The boreal forest is one of the largest forest ecosystems in the world, covering 14.7 million km2 globally. The Canadian boreal forest has a wealth of natural resources, including coal, timber, and oil; as resource exploration and exploitation has expanded, anthropogenic disturbance in the boreal...

Fall 2015
Predation by grey wolves (Canis lupus) has been identified as an important cause of boreal woodland caribou (Rangifer tarandus caribou) mortality. Wolves have been hypothesized to use human-created linear features such as seismic lines, pipelines and roads to increase ease of movement resulting...

Abstract Literature has the power to change lives. Most English teachers trust this to be true. But while there are numerous arguments, of varying merit, that defend literature on cognitive grounds, few studies convincingly point to the underlying mechanisms of what makes it ‘work,’ or explain...

A ubiquitous problem for all foragers is the trade-off between acquiring food energy while simultaneously avoiding the risk of predation. In central montane Alberta I modelled how ungulate forage changes with succession within cutblocks and the implications for forage availability to ungulates...

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...

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...
