This week, Ecohydrology Group Members are presenting their research at the 2015 AGU Fall Meeting (December 14-18, 2015) in San Francisco. With nearly 24,000 attendees, AGU Fall Meeting is the largest Earth and space science meeting in the world.
Fereidoun Rezanezhad and Geertje Pronk from the Ecohydrology Research Group organized a session entitled “Response of Terrestrial Ecosystems Biogeochemistry to Dynamic Hydrological and Climatic Drivers” with 8 oral and 26 poster presentations.
