The AGU Fall Meeting is accepting abstracts for the session “GC051 Thresholds in Soil Response to Global Change ” to be held December 9-13, 2013 in San Francisco CA.
Abstract Deadline: August 6, 2013.
Description: Global change impacts and response are mediated strongly by soils, the core component of the Earth=B9s critical zone. The capacity of the soil system to withstand global-scale perturbations (e.g., climate or land use change, spread of invasive species) may depend on non-linear thresholds in soil state and function as these forcing factors increase in extent and severity. This session explores thresholds of change in soil state and function to better understand vulnerability to global change. Studies that focus on non-linear shifts carbon storage and release in soil, novel isotopic fractionation, changes in soil-water interactions to better understand non-linear thresholds in soil condition, water transport and chemistry are encouraged.
