Land Biogeochemical Cycling Under Global Environmental Change: Patterns, Drivers, and Mechanisms
Land Biogeochemical Cycling Under Global Environmental Change: Patterns, Drivers, and Mechanisms
Session ID#: 162127
Session Description:
The terrestrial biosphere plays a major role in global biogeochemical cycling and land-atmosphere interactions. Global environmental changes such as CO2 fertilization, drought, warming, precipitation variability, and other anthropogenic disturbances can have large influences on terrestrial vegetation and soils and thus on energy, and biogeochemical fluxes (carbon, water, and nutrients) across broad spatio-temporal scales. As global change is expected to accelerate in the future, vegetation is likely to be affected by large-scale tree mortality, shifts in species composition and changes in vegetation cover. Changes in soil chemistry and metabolic activity will influence plant roots and soil microbial communities with a likely strong feedback on vegetation. This session focuses on novel insights on patterns, drivers and mechanisms governing land biogeochemical cycling. We welcome submissions on vegetation and soil microbial dynamics, aboveground and belowground linkages, and their impact on energy and biogeochemical cycling and climate, including observational, experimental and modeling approaches, and studies from local to global scale.
