Fall 2023
Grasslands cover 30% of the planet’s terrestrial surface and provide habitat and forage for livestock and wildlife. In addition, grasslands have the potential to mitigate climate change by sequestering substantial amounts of carbon (C) in the soil. However, the ability of grassland soils to...

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...

Biogeochemical Cycling and Microbial Communities in Native Grasslands:Responses to Climate Change and Defoliation
DownloadSpring 2010
Ongoing climate change has emerged as a major scientific challenge in the current century. Grassland ecosystems are considered net carbon (C) sinks to mitigate climate change. However, they are in turn, influenced by climate change and management practices, providing feedback to climate change...

Clipping and Watering Effects on Caespitose and Rhizomatous Grasses: Implications for Grazing Management
DownloadSpring 2014
Recent experimental evidence suggests that rotational grazing, despite strong perceptions to the contrary, does not promote plant community productivity relative to continuous grazing on rangelands. However, clipping studies from tame pastures of Alberta’s Aspen Parkland show clear plant...

Consequences of altered precipitation, warming, and clipping for plant productivity, biodiversity, and grazing resources at three northern temperate grassland sites
DownloadSpring 2013
There is limited understanding about how altered precipitation and warming associated with climate change affect grassland systems. Also, although grasslands commonly support herbivores, it is unclear how grazing influences responses to climate change. To address these knowledge gaps, I carried...

Cost-effective Conservation Planning for Species at Risk in Saskatchewan’s Milk River Watershed: The Efficiency Gains of a Multi-species Approach
DownloadSpring 2012
The federal Species at Risk Act requires economic analyses to be included in species at risk recovery plans. Recovery plans are often completed species by species and their economic analyses fail to employ modern analytical methods. A unique multi-species at risk recovery plan within...

Effect of Grazing on Litter Decomposition and Extracellular Enzyme Activity across Agro-climatic Subregions in Alberta
DownloadFall 2017
Grasslands cover approximately 40% of the Earth’s terrestrial surface and provide a wide range of ecologically and economically important services such as forage production, carbon (C) and nitrogen (N) storage, and wildlife habitat. Livestock grazing is a ubiquitous use of grasslands around the...

Effects of environmental and disturbance gradients on native bee diversity, abundance and composition in Alberta’s prairies
DownloadFall 2017
Native bees provide pollination services to a range of crops, supporting food production and the global economy. They also support the fitness of native flowering plants and terrestrial plant diversity. These functions are delivered by a diverse community of bees with a broad spectrum of life...

Spring 2016
Understanding factors affecting elemental carbon stocks on Alberta’s grasslands is of special importance with recent policy shifts focusing on climate change and carbon (C) emissions. A large part of Alberta is native prairie utilized by the beef industry. This study examined soil and vegetation...

Fall 2017
Bees are a key component of terrestrial ecosystems and provide valuable ecosystem services to both natural and agricultural landscapes. It estimated that 87.5% of native plants benefit from pollination, including 1/3 of global food crops. Additionally, pollination by bees provides maximized...
