In the  Laboratorio de Ecología Ecosistémica y Biogeoquímica Tropical (Tropical Ecosystem Ecology and Biogeochemistry Lab) at the Escuela de Biología of the Universidad de Costa Rica,  we are interested in the ecosystem ecology and biogeochemistry of tropical environments, with a focus on the cycling of carbon and limiting nutrients like phosphorus.  We use  a mix of old-school ecology tools with state-of-the-art techniques such as 31P and 13C nuclear magnetic resonance (NMR) spectroscopy, to test ecological hypotheses. Some of the questions we are interested in are:

  • What is the fate of  tropical soil carbon sinks in the face of global environmental change,  such as changes in rainfall regimes and atmospheric nutrient deposition?
  • How do long-term changes in nutrient availability influence tropical forest function and structure?
  • Which processes control the bioavailability of phosphorus in tropical soils? Where and how do plants acquire this scarce resource?
