Professor Benton Taylor Named Fellow of the Ecological Society of America
Benton is an ecosystem ecologist working to understand how terrestrial ecosystems will respond to global change, and what the consequences will be for future carbon cycling. His work spans from tropical rainforests to the arctic tundra, focusing primarily on how plant-microbial partnerships impact ecosystem responses to rising carbon dioxide levels, warming, drought, severe weather, nutrient pollution and human land use.
