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...

Biodiversity loss endangers ecosystem services and is considered as a global change that may generate unacceptable environmental consequences on the Earth system. Global biodiversity observations are needed to provide a deep understanding of the biodiversity - ecosystem services relationship and...

Prairie wetlands provide many important ecosystem services including supporting biodiversity, improving water quality, preventing erosion, recharging groundwater, and attenuating floods. However, more than half of prairie wetlands in North America have been lost, primarily due to drainage for...

Fall 2014
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...

Composition and structure of spider assemblages in layers of the mixedwood boreal forest after variable retention harvest
DownloadFall 2011
Natural disturbances are important drivers of ecosystem change in the boreal forest and new approaches to sustainable forest management draw on natural disturbance patterns as a template for harvesting. The main premise for such approach is that species have evolved and adapted to stand-replacing...

Designing an incentive program to reduce on-farm deforestation in the East Usambara Mountains, Tanzania
DownloadFall 2011
This thesis is a set of two papers on the design of a ‘payment for ecosystem services’ (PES) program for the reduction of on-farm deforestation in the East Usambara Mountains, Tanzania. The forests of this area are internationally recognized as one of the world’s most biodiverse ecosystems;...

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...

Fire history, landscape biodiversity and indicators for sustainable management of the boreal mixedwood forest
DownloadSpring 2012
I examined the response of invertebrate assemblages to the forest mosaic established by past fire events, and tested the performance of trees as biodiversity surrogates in accurately reflecting relationships between fire history and invertebrate assemblages. Over 80 % of the studied landscape...
