Dear Colleagues, Please consider our new session on how water limitation impacts terrestrial cycling of water, energy, and biogeochemicals. We invite contributions from both hydrological (catchment) and ecological perspectives. We are excited to hear from invited speakers Ben Poulter (NASA) and Mike Goulden (UC Irvine).
You may find session details below or at https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session13596 and submit your abstract at http://fallmeeting.agu.org/2016/abstract-submissions/ B082: The impacts of water limitation on terrestrial ecosystems and catchments: integrating measurements and models across scales *Session ID#: *13596 Session Description: This session presents diverse methods to understand and predict impacts of water limitation on terrestrial cycling of water, energy, and biogeochemicals. Global-scale studies suggest that water-limited regions dominate the increasing trend of the terrestrial CO2 sink and the interannual variability of atmospheric CO2, and that water limitation affects most terrestrial biomes. Research shows terrestrial processes are increasingly sensitive to water due to vegetation change or CO2 fertilization, while other work suggests nutrient constraints. Comparatively little is known about water limitation of non-CO2 gases and other ecohydrological processes. We encourage submissions that show how combining models and observations can represent processes across spatial scales (e.g. soil collar, leaf, ecosystem, catchment, continent) or leverage longer-tem datasets to address questions across times scales including: 1) fast ecohydrological responses to weather, 2) interannual variability, 3) response to extreme events, and 4) multi-year trends (e.g. in response to changing temperature, precipitation patterns, or [CO2]).
