An adaptive approach to endangered species recovery based on a management experiment: reducing moose to reduce apparent competition with woodland caribou
DownloadFall 2013
Species that are rare yet widely distributed are among the most challenging to conserve. The mountain ecotype of woodland caribou (Rangifer tarandus) is declining because of apparent competition with non-caribou ungulates (NCU) such as moose (Alces alces). I experimentally assessed whether...

Fall 2015
The boreal ecotype of woodland caribou (Rangifer tarandus caribou) is federally listed as Threatened due to population declines throughout its distribution. High mortality rates of neonate calves (≤ 4 weeks old) due to predation are a key demographic factor contributing to population declines...

Fall 2013
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...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada
DownloadFall 2012
Lambert Koizumi, Catherine M S
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...

Disruption in place attachment: Insights of young Aboriginal adults on the social and cultural impacts of industrial development in northern Alberta
DownloadFall 2009
People living in the north have been and will continue to be affected by increasing exploration and exploitation of the region's natural resources. To understand the human impacts a qualitative approach and sense of place, place attachment, and disruption in place theories were used to analyze...

EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

Experimental evidence for the rapid evolution of behavioral canalization in natural populations
Download2009
Lynch, B.R., Trussell, G.C., Palmer, A.R., Edgell, T.C.
Canalization—the evolutionary loss of the capacity of organisms to develop different phenotypes in different environments— is an evolutionary phenomenon suspected to occur widely, although examples in natural populations are elusive. Because behavior is typically a highly flexible component of an...

Fall 2015
Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...

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...
