Understory protection is a harvesting approach that seeks to protect understory conifers during hardwood harvesting in mixedwood forests. While understory protection harvesting has been implemented for over a decade in Alberta, there has been no study of its ecological value to birds. We surveyed...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada

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...

Transportation networks are expanding rapidly to meet increasing global demands to move people and cargo. These networks are essential to connect societies and economies but have several negative effects on wildlife populations including collisions with vehicles. Growing incidences and increasing...

The Mackenzie Delta region, NWT, has a short growing season and highly seasonal climate, and brown bears (Ursus arctos) there face many challenges obtaining their nutritional requirements. Consumption of meat by brown bears is linked to increases in population density, fecundity, growth and body...

Human-wildlife conflicts are a global conservation challenge. Reserves and protected areas usually do not adequately provide for the space needs of large carnivores, resulting in overlap between carnivore home ranges and private lands. Private lands often can provide valuable habitats, but...

A major side-effect of industrial activity is the associated linear-feature footprint and increase in recreational access. Alberta’s threatened grizzly bear (Ursus arctos) populations overlap with a multitude of different potential forms of human disturbance, including human recreational...

Individual and Seasonal Variation in Grizzly Bear Selection for a Railway and other Linear Features in Banff National Park, Canada
DownloadFall 2016
Mortality caused by collisions with trains affects numerous species globally and has increased recently to threaten the grizzly bear (Ursus arctos) population protected in Banff and Yoho National Parks, Canada. Although train collisions are the ultimate cause of mortality, the more proximate...

The potential influence of mountain pine beetle (Dendroctonus ponderosae) control harvesting on grizzly bear (Ursus arctos) food supply and habitat conditions in Alberta
DownloadFall 2012
In response to the mountain pine beetle (Dendroctonus ponderosae) threat in Alberta, forest companies plan to surge harvest 75% of susceptible (mature) lodgepole pine (Pinus contorta) stands over 20 years. To assess potential changes to grizzly bear (Ursus arctos) habitat, I projected food...
