B51C:
Tropical Forests Under a Changing Environment I


Submit an Abstract to this Session


Session ID#: 59966

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 determining Earth’s energy balance.  Thus, a better understanding of tropical forest processes is required to develop improved Earth System Models (ESMs). Improving the representation of processes relevant to the tropics in ESMs requires a tight coupling of model development and process-based field and lab investigations.  This session will focus on research in tropical forests from an Earth system perspective including modeling, remote sensing and measurement results. Processes to be highlighted include the response of tropical forest ecosystems to

(i) extremes weather events (e.g. drought, heat waves, and extreme rainfall),

(ii) changing disturbance/demographic/CO2/rainfall/warming rates,

(iii) internal modes of climate variability (e.g. EL Niño), and

(iv) the role of biodiversity and biogeochemistry in modulating these processes.
