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...

Direct and indirect drivers of plant diversity responses to climate and clipping across northern temperate grassland
Download2014
Bork, E. W., White, S. R., Cahill Jr, J. F.
It is well known that climate can influence plant community assembly via a multitude of indirect and direct pathways. However, interpretations of plant diversity responses to simulated climate change experiments, and subsequent predictions of plant communities under future climate scenarios,...

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...

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...

Low intensity surface fire instigates movement by adults of Calosoma frigidum (Coleoptera, Carabidae)
Download2011
Jacobs, J. M, Work, T. T., Spence, J. R., Bergeron, J. A. C.
Abstract: The genus Calosoma (Coleoptera: Carabidae) is a group of large, sometimes ornate beetles, which often voraciously attack caterpillars. Many studies have reported Calosoma beetles being highly conspicuous during defoliator outbreaks. Based on observations of individual beetle behavior,...

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...

Monitoring year-to-year variability in dry mixed-grass prairie yield using multi-sensor remote sensing
DownloadFall 2012
The Normalized Difference Vegetation Index (NDVI) and harvested biomass were compared to assess rangeland productivity (above-ground green biomass or “yield”) in southern Albertan dry mixed-grass prairie. Seasonal trends during the 2009 and 2010 growing seasons were investigated using harvested...

Irving, B.D., Fedkenheuer, A.W., Bietz, J., Naeth, M.A., Lees, A.T.
Field sites for this study were established in 1987 shortly after the completion of construction of two pipelines in southern Alberta. The Dry Mixed Grass and Mixed Grass Ecoregions (Milo Pipeline Lateral) and the Aspen Parkland, Montane and Fescue Grassland Ecoregions (Porcupine Hills Lateral)...
