Ecology and Evolution of Infectious Disease – Palouse  

Our limited understanding of the relationships between biodiversity, land use patterns, and the transmission of zoonotic pathogens in wildlife hinders our ability to predict and control zoonotic pathogen spillover from wildlife to humans, domestic animals, and livestock.

Mining the microbiome to boost chickpea nutritional quality

Failure to consume sufficient nutrients is a global problem. Microbes profoundly affect nutrient cycling and availability in the rhizosphere which can directly affect crop nutritional quality. The major goal of this project is to harness the plant microbiome to enhance chickpea’s nutritional quality.

Rose Creek and Fourmile Creek Riparian Restoration and Bio-Engineering Projects

The Palouse Conservation District has partnered with WSU and Smoot Hill operations to install two riparian restoration and bio-engineer stream enhancement projects. These include a 9-acre restoration project on Rose Creek and a 16-acre restoration project along Fourmile Creek. Since Fall 2022, about 3,000 plants have been installed at Rose Creek and 1700 at Fourmile Creek.
