Spring 2013
The Rocky Mountain apollo butterfly, Parnassius smintheus, and its host-plant Sedum lanceolatum, are endemic to open alpine meadows threatened by the encroachment of trees. I explore variability in interactions between P. smintheus and S. lanceolatum relative to the treeline-delimited meadow...

Polar bear (Ursus maritimus) foraging, spatial, and energetics ecology in the changing Arctic
DownloadFall 2020
Climate warming in the Arctic has resulted in rapid and extensive changes to sea ice dynamics and profound ecological impacts, including changes to the timing of life history events, community structure, and food web dynamics. Sea ice-dependent species such as polar bears (Ursus maritimus) are...

Political Governance, Socioeconomics, and Weather Influence Greenhouse Gas Emissions across Subnational Jurisdictions in Canada
DownloadSpring 2023
The drastic and immediate reduction of global greenhouse gases (GHG) is vital if humanity is to avoid the moderate to severe effects of a changing climate. To successfully lower these emissions, it is necessary to integrate and harmonize GHG reduction policies across horizontal and vertical...

Population, individual and behavioural approaches to understanding the implications of habitat change for arctic ground squirrels
DownloadFall 2012
The ecological niche describes the entire set of resources and environmental conditions suitable for species to occur and persist. In northern ecosystems, rapid climate change appears to be altering these conditions and increasing the likelihood of shifts in distribution and abundance of species,...

Potential carbon losses from peat profiles: effects of temperature, drought cycles and fire
Download1992
Wein, R. W., Hogg, E. H., Lieffers, V. J.
Abstract: Global warming and the resultant increase in evapotranspiration might lead to lowered water tables in peatlands and an increase in fire frequency. The objective of this study was to investigate some of the potential effects of these changes on peat decomposition. Dry mass losses and...

Potential effects of climate change on tree species and ecosystem distribution in British Columbia
Download2006
A new ecosystem-based climate envelope modeling approach was applied to assess potential climate change impacts on forest communities and tree species. Four orthogonal canonical discriminant functions were used to describe the realized climate space for British Columbia's ecosystems and to model...

Potential impact of climate change to the future climate and streamflow of the Mackenzie River Basin
DownloadFall 2016
The Mackenzie River provides a critical corridor for Canada’s Arctic transportation network and the Mackenzie River Basin (MRB), the largest river basin of Canada, has been subjected to the impact of climate change. In this study, we have investigated the potential impacts of climate change on...

Belikov, S. E., Maslanik, J., Aars, J., Born, E. W., Amstrup, S. C., Serreze, M. C., Stirling, I., Wiig, O., Nielson, R. M., DeWeaver, E., Durner, G. M., Bailey, D. A., McDonald, T. L., Mauritzen, M., Holland, M. M., Derocher, A. E., Douglas, D. C.
Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and...

Thiemann, G. W., Molnár, P. K., Derocher, A. E., Lewis, M. A.
Polar bear (Ursus maritimus) populations are predicted to be negatively affected by climate warming, but the timeframe and manner in which change to polar bear populations will occur remains unclear. Predictions incorporating climate change effects are necessary for proactive population...
