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...

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...

Tonn, W.M., Katopodis, C., Jones, N.E., Scrimgeour, G.J.
We examined spatiotemporal variation in the physical, chemical, and biological characteristics of pristine streams that represent a range of conditions near Lac de Gras in the Barrenlands region of the Northwest Territories, Canada. Principal component analysis organized streams into four groups...

Habitat protection has been identified as an important strategy for the conservation of woodland caribou (Rangifer tarandus). However, because of the economic opportunity costs associated with protection it is unlikely that all caribou ranges can be protected in their entirety. We used an...

Arthritis in the Canadian Aboriginal population: north-south differences in prevalence and correlates
Download2010
Ng, Carmina, Chatwood, Susan, Young, T. Kue
"Background: Information on arthritis and other musculoskeletal disorders among Aboriginal people is sparse. Survey data show that arthritis and rheumatism are among the most commonly reported chronic conditions and their prevalence is higher than among non-Aboriginal people. Objective: To...

Predicting local and nonlocal effects of resources on animal space use using a mechanistic step-selection function.
Download2013
Schaefer, J., Bastille-Rousseau, G., Murray, D., Lewis, M.A., Potts, J.R.
Predicting space use patterns of animals from their interactions with the environment is fundamental for understanding the effect of habitat changes on ecosystem functioning. Recent attempts to address this problem have sought to unify resource selection analysis, where animal space use is...

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...

Characteristics and prevalence of the metabolic syndrome among three ethnic groups in Canada
Download2005-11-22
Liu, Juan, Hanley, Anthony J. G., Young, T. Kue, Harris, S. B., Zinman, Bernard
"Objective: To compare the characteristics and prevalence of the metabolic syndrome (MetS) among Native Indians, Inuit, andnon-Aboriginal Canadians. Methods: The study was based on four cross-sectional studies conducted in the late 1980s and early 1990s involving threeethnic groups living in...
