Dear Colleagues,
We invite you to consider submitting an abstract to our European
Geophysical Union session:
SSS6.9/IG14 Predicting organic matter decay responses to changing
environments: isotopic, kinetic, and ecological approaches
Accurate predictions of atmospheric CO2 concentrations depend on our
ability to project microbial responses to changing temperature and
moisture regimes. Microbial physiology exhibits direct responses to
temperature, with associated changes in carbon and nutrient demand.
In addition to these direct effects of temperature, microbes'
environments change with temperature in ways that can induce indirect
effects. For example, temperature can influence the relative
availability of assimilable resources released via exo-enzyme
activities, and microbes must cope with these resource changes.
Changing moisture regime can either limit or promote diffusion of
substrates and exo-enzymes to reaction sites. The changing
availability of assimilable resources accompanying these shifts in
temperature and moisture may promote microbial populations that can
exhibit plastic stoichiometry. Integrated over spatial and temporal
scales, these differential responses may result in complex patterns
of CO2 fluxes from soils. We invite investigators exploring these and
related issues to help predict microbially mediated decay and
respiratory loss of CO2.
We anticipate a lively session given the current relevance of this
topic in the literature.
