Characteristics of alpine plants and soils along an elevational gradient, Northern Selkirk Mountains, British Columbia
DownloadSpring 2019
Rates of climate change are accelerated at higher elevations, a pattern termed elevation-dependent warming (EDW). Consequently, the impacts of climate change on community patterning and soil development may be particularly evident in alpine environments. Alpine ecotone boundaries, such as...

Europe going green? The European Union's promotion of a global mitigation norm on climate change
Fall 2011
Greenhouse gas emissions need to peak by 2020 to avoid dangerous climate change. Yet, emissions are rising, particularly in emerging economies like China. A global agreement on curbing emissions, which includes all major emitters, is urgently needed. Has the European Union (EU) contributed to the...

Habitat Use in Undisturbed Forest and the Effect of Variable Retention Harvesting on Pollinator Assemblages (Apoidea, Syrphidae) in the Boreal Forest of Alberta
DownloadSpring 2019
While pollination in agricultural areas has been well studied, pollinators in forests have received much less attention, particularly in the boreal forest. Bees, especially native bees, and hoverflies are the two most important groups of pollinators providing crucial ecological and economical...

Gender-differentiated Innovations in Response to Climate Change: Evidence from Smallholder Agriculture in 4 countries in East Africa
DownloadSpring 2014
We investigate gender differentiated innovations regarding maize production among households in Ethiopia, Kenya, Tanzania and Uganda. We find that innovation is positively influenced by access to information assets and on farm water, amount of land, and number of income sources, with Kenya and...

Spring 2010
The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...

The ecology of a re-established cougar (Puma concolor) population in southeastern Alberta and southwestern Saskatchewan
DownloadFall 2010
Cougars (Puma concolor) have recently begun to reclaim former range and also are expanding into new territory. The Cypress Hills of southeast Alberta and southwest Saskatchewan now hosts the most eastern confirmed breeding population of cougars in Canada. However, with the return of cougars come...

The Spatiotemporal Occurrence and Recovery of Shiga Toxin-producing Escherichia coli (STEC) in Well-sourced Drinking Water from Southern Alberta, Canada
DownloadFall 2018
Shiga toxin-producing Escherichia coli (STEC) are important enteric pathogens that cause significant morbidity and mortality worldwide, as well as in Canada. Drinking water is a key exposure pathway for STEC infection and the occurrence of these pathogens in drinking water sources represents an...

Fall 2019
Although typically referred to as a generalist species, individual prey specialization has been documented in cougars (Puma concolor). This behaviour has the potential to limit and regulate ungulate dynamics, particularly in cases where ungulates exist in small or isolated populations. Cougars...

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,...
