Spring 2018
Climate change will continue to affect the Arctic more intensely than other biomes. These changes can have dramatic effects on biotic interactions that influence the functioning of these systems, including plant-herbivore interactions. Invertebrate herbivores strongly depend on external...

Spring 2016
After decades of recent fire exclusion in southern Alberta, Canada, forests are progressively aging and landscape mosaics are departing from their historical conditions. A large-scale fire history study spanning three natural subregions: Subalpine, Montane and Upper Foothills, was undertaken to...

Spring 2016
Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...

Examining the impact of climate change on snowshoe hare demography and community interactions in the northern boreal forest
DownloadSpring 2020
Ecologists are under increasing pressure to predict the influence of climate change on species demography along with the broader impacts on community and ecosystem structure. Predicting community responses to climate change, however, is a formidable challenge, that can be ameliorated by...

A Functional Approach Reveals Zooplankton Responses to Environmental Change in Mountain Lakes
DownloadFall 2017
Concern is increasing over the future cumulative impacts of multiple stressors on freshwater biodiversity and ecosystem function, especially in alpine environments where climatic warming increases with elevation. Here, consideration of individual species traits enables translation of changes in...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...

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...

Analytical developments in the use of resemblance measures in community ecology and applications to boreal forest Carabidae
DownloadFall 2012
Understanding the factors influencing the distribution of species is one of the main goals of ecology. This thesis presents three contributions to better and more efficiently understand the factors defining the composition of ecological communities. First, I studied the impact of anthropogenic...
