Wildfire shapes the boreal ecosystem in western Canada and thereby enhances and diminishes important breeding habitat for many songbird species. Two aspects of wildfire, burn severity and time since fire, fundamentally alter the forest structure that songbirds use. The objectives of this study...
Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal abilityDownload
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...
Changes in peatland plant community composition and stand structure due to road induced flooding and desiccationDownload
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...
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 PrairieDownload
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, CanadaDownload
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 WildlifeDownload
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...
Effects of energy development on habitat use of an avian peatland specialist and generalist at multiple spatial scalesDownload
With the persistent demand for petroleum energy products, the energy development footprint in northern Alberta continues to expand, perforating habitat in the boreal forest. Modern in situ, or below ground, bitumen extraction techniques have broadened the extent of accessible reserves and are...
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...
Threatened woodland caribou (Rangifer tarandus caribou) have experienced large range recessions and population declines across much of Canada’s boreal forest in the last century and have become a major focus of conservation efforts in the region. Habitat management strategies for woodland caribou...
