Tropical forests under a changing environment

Session ID#: 77945

Session Description:
Tropical forests comprise the most biologically diverse terrestrial ecosystems, cycle more carbon and water than any other biome, and play critical roles in the global and regional climate systems.  A better understanding of tropical forest processes is required to advance our understanding of the Earth system and to develop improved Earth System Models (ESMs).  Improving representation of tropics-relevant processes in ESMs requires a tight coupling of model development and process-based field and laboratory investigations.  This session will focus on research in tropical forests including modeling, remote sensing and ground-based results. Processes to be highlighted include the response of tropical forest ecosystems to:

  1. global change pressures, such as land use change/changing demographics/increased atmospheric CO2/altered rainfall/warming,
  2. extreme weather events (e.g., drought, heat waves, and extreme rainfall),
  3. climate variability (e.g., EL Niño), and
  4. role of biodiversity, biogeochemistry (including soil fertility, nutrient limitation, soil respiration, and carbon sequestration), and phenology in modulating these processes.
