Fall 2017
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...

Benthic Responses to Nitrogen and Phosphorus Deposition on Alpine Ponds in Banff National Park: A Replicated Whole-Ecosystem Experiment
DownloadFall 2012
Nitrogen (N) and Phosphorous (P) deposition at high elevations has increased by 40% over the last fifteen years, causing concern for the 3000+ alpine ponds in Banff National Park. A novel whole-ecosystem experiment was used to test for the effects of elevated N and P deposition on benthic...

Fall 2016
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 2016
Western North American landscapes are rapidly being transformed by forest die- off caused by mountain pine beetle with implications for plant and soil communities. The mechanisms that drive changes in plant and soil community structure and function, particularly for understory vegetation and the...

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;...

Disentangling competitive processes to better understand their drivers and consequences in a native grassland community
DownloadSpring 2021
Competition is often highlighted as a major force influencing community structure. However, there are multiple facets of competition that may have independent and differential impacts, making the understanding of what drives competition and how it structures communities difficult. In this thesis,...

Factors affecting meiofaunal colonization and assemblage structure in marine soft sediments
DownloadFall 2009
Meiofauna are an abundant, diverse and important component of the marine biota, however, much of their ecology has been neglected. Despite their high densities, meiofaunal abundance is often patchy. Meiofauna present in high numbers at one site will often be less abundant in seemingly similar...

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...
