session 070 – Source, speciation, transformation and transport of C, N, and P from terrestrial to freshwater systems
Carbon (C), nitrogen (N), and phosphorus (P) are nutrients often limiting net primary production in aquatic environments. Terrestrial systems are significant sources of these nutrients entering aquatic systems and their nature and availability influence algal biomass production and seasonal dynamics. An understanding of the effects of land management practices on the sources of C, N and P as well as the speciation and transformations of these nutrients in both terrestrial and freshwater systems is critical for controlling the balance of these nutrients in the aquatic environment. The aim of this session is to bring together researchers working on factors affecting speciation and transformation of C, N and P during transport along the terrestrial to freshwater system continuum, including the empirical nutrient signatures and ratios or different source areas and the kinetics of processes transforming nutrient species.
