Research

Range Plant Physiology

Research into carbon allocation, photosynthesis, and root exudation in range grasses, nitrogen cycling associated with fire in tallgrass prairie; effect of atmospheric carbon dioxide enrichment on the tallgrass prairie ecosystem and carbon, water vapor, and energy fluxes of tallgrass prairie; impact of grazing on carbon allocation strategies including photosynthetic pathway effects; carbon sequestration under different land use practices.

Grazing Systems

Development of economically and ecologically efficient grazing systems for stocker and cow/calf enterprises.

Range Burning

Research into the effects of range burning on plant and animal components of range ecosystems.

Prairie Management & Research

Development of GPS/GIS databases and tools for research and management of prairie.
