A Functional Approach Reveals Zooplankton Responses to Environmental Change in Mountain Lakes
DownloadFall 2017
Concern is increasing over the future cumulative impacts of multiple stressors on freshwater biodiversity and ecosystem function, especially in alpine environments where climatic warming increases with elevation. Here, consideration of individual species traits enables translation of changes in...

Assessing stress in western Hudson Bay polar bears using hair cortisol concentration as a biomarker
DownloadFall 2015
The development of novel biomarkers to help assess whether polar bear (Ursus maritimus) health is impacted by long-term physiological stress associated with climate change represents an emerging area of research. With progressively greater reductions in sea ice cover and a corresponding decrease...

Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate change
DownloadFall 2013
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...

American black bears (Ursus americanus) and grizzly bears (U. arctos) have similar habitat requirements, relying on seasonally available grasses, forbs, fruiting shrubs and trees, and neonate ungulates. To avoid aggressive encounters with grizzly bears, black bears partition habitats spatially...

Caribou (Rangifer tarandus L.) populations in Canada are threatened by climate change and anthropogenic landscape disturbance, which may negatively affect caribou energetics and range occupancy, with negative consequences for vital rates. Caribou are the basis of economy and spirituality for...

The field of animal personality, the study of adaptive among-individual behavioural differences in animal populations, has both exploded in popularity in the last few decades and come under heavy scrutiny by behavioural ecologists. The sudden interest in the field stems from the widespread...

Climate Change Impacts on Stoichiometry, Phytoplankton, and Zooplankton in Alpine Lake Food Webs
DownloadFall 2013
The main hypothesis of this study was that warmer and drier conditions affect fishless alpine lakes by increasing (1) phosphorus (P)-availability, (2) P-limited autotrophs versus mixotrophic phytoflagellates, and (3) fast-growing P-limited cladocerans versus slower-growing nitrogen (N)-rich...

Consequences of altered precipitation, warming, and clipping for plant productivity, biodiversity, and grazing resources at three northern temperate grassland sites
DownloadSpring 2013
There is limited understanding about how altered precipitation and warming associated with climate change affect grassland systems. Also, although grasslands commonly support herbivores, it is unclear how grazing influences responses to climate change. To address these knowledge gaps, I carried...

Conserving cougars in a rural landscape: habitat requirements and local tolerance in west-central Alberta
DownloadSpring 2011
Maintaining large carnivores in human-dominated landscapes poses a significant conservation challenge. Extirpation is common because of habitat loss or direct persecution. I studied cougar habitat selection and human perception of cougars in west-central Alberta to better understand...

Fall 2023
Global warming is contributing to extreme climatic events, especially at higher elevations and latitudes. Phytoplankton assemblages are highly sensitive to these climate-related environmental changes, which include heatwaves and drought events. Knowledge gaps exist concerning the cumulative...
