A burning question: The spatial response of woodland caribou to wildfire in northeastern Alberta
DownloadSpring 2020
The Canadian Federal Recovery Strategy for woodland caribou classifies areas burned by wildfire in the last 40 years as disturbed habitat for woodland caribou. This delineation of fire disturbance has major economic and social implications across Canada. Caribou have been shown to avoid burned...

Fall 2012
Conservationists have long debated how best to measure and conserve biodiversity. While many scientists called for long-term, large-scale ecological monitoring in the 1990's, the concurrent increased appreciation of statistical power and detectability-related sampling error meant that many...

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...

Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal ability
DownloadFall 2015
Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual populations of species occupy different positions in the landscape...

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...

Changes in peatland plant community composition and stand structure due to road induced flooding and desiccation
DownloadFall 2017
Roads built through peatlands with horizontal water flow can to act as dams that affect local hydrology and thus vegetation composition and structure. On the ‘upstream’ side of roads, soils can become waterlogged causing either increased tree mortality, or stunted tree growth; conversely, the...

Fall 2016
Primates play an important role in the maintenance and functioning of tropical ecosystems. However, habitat loss due to land use conversion threatens the persistence of primates worldwide. Colombia has a diverse fauna of primates with 12% of its terrestrial territory protected under the country’s...

Displacement and Mortality of Birds by High Voltage Transmission Lines in the Canadian Dry Mixed Prairie
DownloadFall 2018
Canadian grasslands are continuing to experience loss in habitat and degradation in quality due to agricultural expansion and fragmentation from roads, pipelines, and transmission lines. Today, only 43% of Canadian mixed grass prairie remains. This loss and fragmentation has led to a decline in...

Distribution and breeding ecology of boreal and northern saw-whet owls in the Boreal forests of Alberta, Canada
DownloadSpring 2018
The boreal forest is an ecologically dynamic region with a long history of natural disturbances. These dynamics now run at a different and more rapid pace in Alberta because of land-use change, forestry, and developments in the energy industry. Although boreal owls Aegolius funereus and northern...

Effectiveness of Retention Harvesting for Biodiversity Conservation: Evidence for Understory Vegetation and Wildlife
DownloadSpring 2018
Natural disturbance emulation is being used in forest management in an attempt to mitigate the negative effects of harvesting on biodiversity. In the western Canadian boreal forest where the predominant large-scale natural disturbance is wildfire, harvests that leave live mature trees behind at...
