ECOS: Tree Species Effects on Ecosystem Processes

This project encompasses a large scale experiment in Costa Rica, laboratory experiments in Iowa, and modeling with CENTURY. We explore how tropical tree species influence ecosystem processes. The focus currently is on carbon and nutrient cycling, microbial processes, ecosystem modeling, and restoration of degraded landscapes.
