Erosion is a dominant process shaping the Earths' surface, but erosion can have complex and counterintuitive effects on ecosystem properties and processes. In this talk I highlight the different ways ecosystem scientists have explored the effects of erosion, with a particular focus in tropical rainforests. These systems cover less than ten percent of Earth's terrestrial surface, but account for around a third of all terrestrial primary productivity. Thus, the interaction between these forests and their geomorphic setting has an outsized role on the global carbon cycle. Understanding the present, and future of productivity in the tropics requires a better understanding of the link between erosion, soils, and forest properties. Lien Zoom:
