Special Session - Ecological Stoichiometry of Catchments: Scaling Our Understanding of Physical, Chemical, and Biological controls I
The catchment provides a spatial scale at which landscape and aquatic processes are integrated into aquatic ecosystem structure and function. What do we currently understand about the ecological stoichiometry of catchments? Can existing knowledge about the stoichiometry of terrestrial ecosystems, transport processes, and aquatic ecosystems be integrated into a holistic understanding of aquatic ecological stoichiometry? We encourage abstracts that explore these questions and present insights into ecological stoichiometry of catchments and their components (e.g., soils, wetlands, lakes, streams). Studies addressing all spatial and temporal scales relevant to aquatic ecosystems are invited. Possible topics of interest would examine spatial variability, temporal variability, spatial scaling patterns, system comparisons, or exploration of controls on stoichiometric processes.
