Mark Bradford, Assistant Professor of Terrestrial Ecosystem Ecology

Mark Bradford

Research Emphasis:

I am primarily interested in how global change (e.g. climate warming) affects plants, animals and microorganisms in grasslands and forests, and what the consequences are for ecosystem carbon cycling and storage.
