Assessment of rumen microbiota in beef heifers with different feed efficiency and managed under different feeding systems
DownloadSpring 2020
The linkage between rumen microbiota and feed efficiency has been studied in cattle managed under the drylot system, especially in the feedlot with high-grain diets. However, pasture-based beef operations still dominate the beef production system around the world. In Alberta and other provinces...

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...

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...

Mechanisms regulating Poa pratensis L. and Festuca campestris Rybd. within the foothills fescue grasslands of southern Alberta
DownloadFall 2011
Invasion of non-native species such as Poa pratensis L. has become a serious threat to the conservation of bunch grass communities including foothills fescue grasslands in Alberta, Canada. Conservation efforts are currently limited by a poor understanding of the ecological mechanisms responsible...
