Research

The Rangeland Research Institute provides researchers with opportunity to conduct a wide range of short- and long-term research projects focused on providing a solid scientific foundation for the sustainable management of rangelands.

We support research that combines expertise and approaches from a variety of academic disciplines and addresses issues related to the competing demands of ecosystem conservation and resource use, including energy exploration and extraction, grazing, water management, wildlife management and biodiversity conservation, and sustainable landscape management.

Ecological and agronomic consequences of Cicer milkvetch (Astragalus cicer L.) introduction into Mixed Prairie grassland

Cicer milkvetch is an introduced legume that is beginning to encroach on native mixed grass prairie plant communities within the Mattheis Research Ranch. By measuring soil properties, plant biomass, and plant community composition in areas with and without cicer milkvetch, Dr. Carlyle and undergraduate student Kyle Le assessed the localized effects of invasions by this species on rangeland ecosystem functions. They found that forage quantity and quality were highest in plots with cicer milkvetch...

Differentiating and understanding the roles of soil nutrient and soil community heterogeneity on plant growth, carbon storage, and biodiversity

Though plant growth in grasslands has historically been viewed from primarily nutritive and topdown perspectives, diverse soil microorganisms have substantial non-nutritive impacts on growth, ecosystem services, biodiversity and invasion. Using a functional approach, Dr. Cahill and co-investigator Dr. Pierre-Luc Chagnon (Killam Post-doctoral fellow, Biological Sciences) will quantify the net effects of soil microorganisms on plant growth and key ecosystem processes within the Mattheis Research R...
