“The End of the Ice Age?”: Visitor motivations to experience disappearing world heritage and the climate change communication imperative
Download2018-01-01
Lemieux, Christopher J., Groulx, Mark, Halpenny, Elizabeth, Stager, Heather, Dawson, Jackie, Stewart, Emma J., Hvenegaard, Glen T.
Rapid environmental change in vulnerable destinations has stimulated a new form of travel termed ‘last chance tourism’ (LCT). Studies have examined the risks of LCT, while leaving potential opportunities within this new tourism market largely underexplored. Results of survey (n=399) research in...

Adaptation of white spruce populations to extreme climate events: implications for assisted migration practices in Western Canada
DownloadSpring 2019
The movement of seed sources from south to north has been proposed as a tool to mitigate the effect of climate change on forest productivity and mortality. Southern provenances, coming from warmer regions are expected to better utilize the extended growing seasons expected under climate warming....

Adaptation of white spruce to climatic risk environments in spring: implications for management under climate change
DownloadFall 2022
The timing of spring dormancy release and bud break in trees is an adaptive trait with potentially important management implications. Depending on how spring phenology is controlled, climate warming may disrupt the synchronization of bud break with the available growing season. Further,...

Anthropogenic influence on the autumn migration of polar bears (Ursus maritimus) in Hudson Bay
DownloadSpring 2022
Migratory species may shift established spatiotemporal patterns in response to anthropogenic impacts, so understanding the energetic consequences of behavioural plasticity may provide insight into how effectively migratory species respond to climate change. I used satellite telemetry to examine...

Burn severity and fire history in the northwestern Canadian boreal forest: drivers and ecological outcomes
DownloadSpring 2019
Wildfire is the dominant stand-renewing disturbance in the northwestern Canadian boreal forest. Fires burn extensive areas in Canada, disturbing an average of 1.96 Mha yr−1, primarily in the boreal zone. Fires generally occur every ~30 – > 200 years in this region, due in part to a lack of fuel...

Changes in Global and Regional Precipitation Patterns under the Impact of Climate Warming: Human Influences, Extremes and Seasonality
DownloadFall 2023
Climate variability and human activities exert significant influences on various components of the hydrologic cycle worldwide. Changes to the global climate system may affect the magnitude and frequency of both mean and extreme hydrological events, thereby changing the risk to critical...

Climate and air quality impacts of boreal wildfires — new analytical approaches for the investigation of light absorption and atmospheric reactivity of wildfire particulate matter
DownloadSpring 2022
Wildfire smoke emissions contain substantial amounts of light-absorbing aerosols that can affect the radiation and cloud processes, resulting in climate impacts on regional and even global scales. The radiative impact of these light-absorbing aerosols is largely contributed by brown carbon (BrC),...

Climate change implications for distribution, phenology and conservation of Olive-sided Flycatchers (Contopus cooperi) and Western Wood-Pewees (C. sordidulus) in northwestern North America
DownloadFall 2020
Northwestern North America is predicted to experience some of the world’s greatest human-caused climate change. Understanding the impacts of associated changes will be imperative to the conservation and management of northern-breeding birds. In particular, long distance migrants and aerial...

Effects of retrogressive thaw slumping on particulate organic carbon dynamics in the Northwest Territories, Canada
DownloadSpring 2022
Climate change is increasing the frequency and intensity of thermokarst and accelerating the delivery of terrestrial organic material from previously sequestered sources to aquatic systems, where it is subject to further biochemical alteration. Rapid climate change in the glacially conditioned...
