Intrapopulation variability in wolf diet revealed using a combined stable isotope and fatty acid approach
DownloadSpring 2018
Naturally occurring stable isotope ratios and fatty acids are two types of chemical biomarkers frequently used to quantitatively estimate consumer diets. Stable isotope values in animal tissues and diets have been evaluated using Bayesian mixing models to provide dietary estimates of consumers in...

Multiple carnivore species can have greater population limiting effects than single carnivores. Two coexisting carnivores can only be similar up to a certain extent. I investigate how two carnivores, wolves (Canis lupus) and cougars (Puma concolor), coexist through niche partitioning in the...

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...

Managing the cumulative impacts of land uses in the Western Canadian Sedimentary Basin: A modeling approach.
Download2003
Wasel, S., Schneider, R., Boutin, S., Stelfox, J.
This case study from northeastern Alberta, Canada, demonstrates a fundamentally different approach to forest management in which stakeholders balance conservation and economic objectives by weighing current management options from the point of view of their long-term effects on the forest....

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...

Movement ecology thrives from a successful synergy of data and models. In a field where experiments are difficult or impossible, linking field data with mathematical and statistical models allows us to test hypotheses and increase our quantitative understanding of movement processes. Owing to...
