Jim P. Muir

    James P. Muir, a Fellow of the American Society of Agronomy, is Regent’s Professor and Research Scientist with Tarleton and Texas A&M AgriLife Research.  He is a grassland ecologist focusing on the plant/animal interface.  He has research currently on-going in South Sudan, South Africa, Swaziland, Brazil, and throughout Texas.  His students have undertaken research or presented their data in many countries, including Argentina, South Africa and Malaysia.  His long-term focus has been legumes, both cultivated and natural, and their myriad roles in pastures, rangeland, prairies and savannahs.  Currently his multi-national team is looking at the many facets of legume condensed tannins as they affect plant survival, herbivory, carbon sequestration as well as animal and environment health.  He is also interested in domesticating native Texas legume ecotypes for many uses, including prairie restoration and roadside revegetation.
