Nutrient Dynamics and Biogeochemical Cycling

small pothole wetland at St Marks NWR Nutrient dynamics and biogeochemical cycling are fundamental properties of ecosystems that can be altered by large-scale human activities such as nutrient enrichment, hydrologic alteration, sea-level rise, and atmospheric carbon dioxide increases. Researchers are investigating alterations in biogeochemical cycling in a diverse range of ecosystems including rivers, lakes, wetlands, and estuaries.

Researchers at the National Wetlands Research Center are working with other federal agencies and universities to study the effects of anthropogenic disturbances on biogeochemical cycling in a diversity of aquatic ecosystems. Ongoing research efforts include effects of nutrient enrichment on euphotic estuarine sediments, effects of exotic invasive plants on lake limnology, enrichment effects of rainfall on lake phytoplankton, and baseline water quality characteristics of the aquatic ecosystems in southern forested wetlands.
