Simulated Livestock Soil Compaction, Plant Defoliation and Litter Removal Effects on Extracellular Enzyme Activity and Vegetation Across a Moisture Gradient in Southern Alberta, Canada
DownloadSpring 2020
Barszczewski, Sara Janina Bodnar
Preservation of grasslands is vital for the continuation of the numerous ecosystem goods and services (EG&S) provided by these ecosystems, including forage for livestock, nutrient cycling, carbon sequestration and habitat for flora and fauna. All EG&S in grasslands are supported by microbial...

The potential of aspen clonal forestry in Alberta: breeding regions and estimates of genetic gain from selection
Download2012
Brouard, J.S., Hamann, A., Gylander, T., Thomas, B.R.
Background: Aspen naturally grows in large, single-species, even-aged stands that regenerate clonally after fire disturbance. This offers an opportunity for an intensive clonal forestry system that closely emulates the natural life history of the species. In this paper, we assess the potential of...

The root distribution, architecture, transpiration and root sapflow dynamics of mature trembling aspen (Populus tremuloides) growing along a hillslope
DownloadFall 2013
The objectives of this study were to explore comparative controls by atmospheric and belowground variables governing transpiration of trembling aspen (Populus tremuloides) growing along a water limited hillslope. Vertical and horizontal root distribution, intra- and inter-clonal root connections,...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...

Wolves Influence Elk Movements: Behavior Shapes a Trophic Cascade in Yellowstone National Park
Download2005
Fortin, D., Beyer, H. L., Smith, D. W., Boyce, M. S., Mao, J. S., Duchesne, T.
A trophic cascade recently has been reported among wolves, elk, and aspen on the northern winter range of Yellowstone National Park, Wyoming, USA, but the mechanisms of indirect interactions within this food chain have yet to be established. We investigated whether the observed trophic cascade...
