THE STOICHIOMETRY OF GLOBAL CHANGE IN AQUATIC ECOSYSTEMS
Major projected anthropogenic perturbations include increased CO2 availability, increased N loading, changes in solar insolation, as well as increased temperature. Our ability to forecast and thus mediate how these factors will influence aquatic ecosystem structure and function has a large stoichiometric component. With current knowlege, we have a reasonable chance at predicting how these different forcing factors will affect aquatic C:N:P ratios. I will review studies on the relationship between C:N:P ratios and ecosystem function such as C storage and food chain production and estimate impacts at the global scale.
