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...

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...

Canada’s boreal forest is the breeding ground for some 288 species of resident and migratory birds. Approximately 65% of the species that are currently of highest conservation priority in the boreal region are associated with wetlands and riparian areas. Although estimates vary with scale and...

Disruption of a belowground mutualism alters interactions between plants and their floral visitors
Download2008-01-01
Cahill, J. F., Shore, B. H., Smith, G. R., Elle, E.
Plants engage in diverse and intimate interactions with unrelated taxa. For example, aboveground. oral visitors provide pollination services, while belowground arbuscular mycorrhizal fungi (AMF) enhance nutrient capture. Traditionally in ecology, these processes were studied in isolation,...

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...

Jackson, D.A., Walker, S.C., Poos, M.S.
Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological...

Abstract: Experimental evidence of trophic cascades initiated by large vertebrate predators is rare in terrestrial ecosystems. A serendipitous natural experiment provided an opportunity to test the trophic cascade hypothesis for wolves (Canis lupus) in Banff National Park, Canada. The first wolf...

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...

Overstory and understory dynamics of whitebark pine (Pinus albicaulis) ecosystems of northwestern British Columbia
DownloadFall 2010
Whitebark pine (Pinus albicaulis) is declining across its range due to disturbances such as mountain pine beetle and white pine blister rust. In this thesis, I assess the response and vulnerability of whitebark pine ecosystems to multiple stressors and disturbances at the northern edge of...
