B010:
Asymmetric responses of ecosystems to changing precipitation regimes: Theory, experiments and modeling approaches





Session ID#: 26285

Session Description:
Precipitation is a primary determinant of terrestrial ecosystem structure and function over much of the globe. Thus, understanding how ecosystems respond to changes in precipitation is important ecologically and to land-atmosphere models that couple terrestrial vegetation to the carbon cycle. Recent evidence has accumulated that many types of ecosystem responses to precipitation are asymmetric, with responses to increases in precipitation differing in magnitude from responses to equivalent decreases. This session will address the theory underlying asymmetric responses to precipitation change, experimental evidence for such responses and the ability of models to capture this phenomenon. Collectively, presentations will identify knowledge gaps, highlight new research directions, and provide a comprehensive perspective to improve our understanding of carbon cycle dynamics as well as forecasts of ecosystem responses to climate change. We invite biogeochemists, climatologists, ecologists, hydrologists, and system modelers to present results relevant to asymmetric responses of terrestrial ecosystems to changes in precipitation.
