Sarah Batterman

Sarah studies nutrient limitation on primary productivity in terrestrial ecosystems. Her work focuses on symbiotic nitrogen fixation, what controls its prevalence, and how patterns of fixation change across heterogeneous tropical forests. She finds symbiotic fixation particularly fascinating not only because plants can use it to bypass the soil to get essential nitrogen and build up nitrogen in the ecosystem, but also because it could help tropical forests store more carbon as atmospheric carbon dioxide levels rise. This would offset some of the world’s carbon emissions.
