Paquet, P.C., Hik, D.S., Frame, P.F., Cluff, H.D.
Wolves (Canis lupus) on the Canadian barrens are intimately linked to migrating herds of barren-ground caribou (Rangifer tarandus). We deployed a Global Positioning System (GPS) radio collar on an adult female wolf to record her movements in response to changing caribou densities near her den...

Long-Term Impacts of Severe Wildfire and Salvage Logging on Macroinvertebrate Assemblages and Food Web Structure in Rocky Mountain Headwater Streams
DownloadFall 2019
Wildfire is an important natural disturbance on forested landscapes influencing both physical and biological processes. The Lost Creek wildfire in 2003 was one of the more severe on Alberta’s eastern slopes and provided a unique opportunity to assess the long-term impacts of wildfire on northern...

Low intensity surface fire instigates movement by adults of Calosoma frigidum (Coleoptera, Carabidae)
Download2011
Jacobs, J. M, Work, T. T., Spence, J. R., Bergeron, J. A. C.
Abstract: The genus Calosoma (Coleoptera: Carabidae) is a group of large, sometimes ornate beetles, which often voraciously attack caterpillars. Many studies have reported Calosoma beetles being highly conspicuous during defoliator outbreaks. Based on observations of individual beetle behavior,...

Modeling the carbon balance of Amazonian rain forests: resolving ecological controls on net ecosystem productivity
Download2009
de Oliveira, R. C., Munger, J. W., Wofsy, S. C., Hutra, L. R., Grant, R. F., Saleska, S. R.
Abstract: There is still much uncertainty about ecological controls on the rate and direction of net CO(2) exchange by tropical rain forests, in spite of their importance to global C cycling. These controls are thought to arise from hydrologic and nutrient constraints to CO(2) fixation caused by...

Patterns in the species composition and richness of fish assemblages in northern Wisconsin lakes
Download1982
Fish assemblage structure, and factors and mechanisms appearing important in the ecological maintenance of these structures, were examined for 18 small lakes in northern Wisconsin during summer and winter. The study was focused around the following questions. Are there discrete, repeatable groups...

Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

Fall 2021
This thesis considers the constitution of urban places, futures and belonging through foraging, urban gardening and recipe creation. Adopting a community-based research approach, the research embraces values of inclusion and is an active attempt to diversify the ways in which urban greenspaces...

Responses in butterflies to loss and fragmentation of boreal forests from in situ oil sands
DownloadSpring 2019
Anthropogenic loss and fragmentation of habitat are a threat to biodiversity, while increasing demands for energy have made the provision of fossil fuels an important source of disturbance to habitats around the globe. In Alberta, Canada, the extraction of a 142,000 km2 oil sands reserve is...

Restoration of Degraded Trail Crossings in Wet and Riparian Areas Using Balsam Poplar Cuttings, Blue Rapids Provincial Recreation Area, Alberta
DownloadSpring 2019
Protected areas are established and maintained in Alberta, Canada for the conservation and preservation of natural features and to facilitate their use and enjoyment for outdoor recreation and education. The use of off-highway vehicles (OHV) is a popular recreational activity in Alberta’s parks....
