Modeling the impacts of recent climate change on ecosystem productivity across North America
DownloadFall 2015
There is evidence of warming and changes in precipitation over recent decades in most regions of North America (NA) that are affecting ecosystem productivity. The impacts of these changes on land-atmosphere carbon exchange over a wide range of biomes are spatially heterogeneous and uncertain. In...

Plastic products have become a necessary part of our day-to-day lives. They are useful because they are incredibly stable and durable, but what are the consequences? Nanoplastics are small pieces of plastic, from 1000 nm to 1 nm, that are either formed in factories or from the degradation of...

Nitrogen Loadings in Stormwater and Snowmelt from Cold-region Urban Catchments in 1991 – 2018 and Prediction for Year 2050
DownloadSpring 2022
Urban stormwater and snowmelt runoff has become a primary source of pollution in receiving water bodies (e.g., rivers, lakes and oceans), causing eutrophication, harmful algae blooms and hypoxia and many other environmental issues. It is therefore imperative to study pollutant loadings from urban...

Abstract This thesis explores the risk perception of climate change among Egyptians who reside in Canada and Egyptians who reside in Egypt. It applies a quantitative comparative analysis of these two populations to assess differences in risk perception of climate change and the influence of world...

Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, Canada
Download2005
McMaster, N. L., Schindler, D. W.
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...

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...
