B51E:
Impacts to Water and Nutrient Cycles in Ecosystems Following Disturbance I Posters

Submit an Abstract to this Session



Session ID#: 25425

Session Description:
Natural and anthropogenic disturbances are widespread across terrestrial ecosystems of the southeastern United States. Disturbances such as fire, floods, extreme weather, and insect/pathogen outbreaks have dramatic effects on ecosystem services including impacts on water, carbon, and nutrient cycles. The large spatial and temporal variability of both disturbance regime and ecosystem response creates a critical need to understand key ecological mechanisms that control feedback loops associated with resiliency or equilibrium change. We encourage contributions providing new insights into methods, measurements, and modeling of the hydrology and biogeochemistry of ecosystem disturbances, with particular focus on the southeastern United States.
