Dear All:
We would like to inform you of the planned AGU 2008 Fall Meeting session
sponsored by the Biogeosciences Section, Fall AGU, San Francisco, CA,
USA. December 14-19, 2008.
B17: Terrestrial ecosystem respiration: identifying sources and controls
Terrestrial ecosystem respiration is the combined flux of CO2 to the
atmosphere from above- and below-ground, plant and microbial sources. Flux
measurements alone (e.g. from eddy covariance towers or soil chambers)
cannot distinguish the contributions from these plant and microbial
sources. The development of process-based models that can predict how
plants and microbes respond to changing environmental conditions require
that field experiments partition the sources of respiration. The purpose
of this session is to assemble studies in which novel approaches have been
applied (or being developed) to separate ecosystem (or soil) respiration
sources and their drivers. This may include the combination of flux
measurements with isotopic techniques, manipulations, gradient studies, or
modeling approaches. In addition, this session welcomes contributions that
can highlight important environmental, biological, or physical controls on
ecosystem (or soil) respiration fluxes over diel, seasonal, interannual, or
decadal time scales.
Abstracts due: 10 September 2008, 2359 UT (Universal Time).
