Physiological ecology of SRS Carolina bay phytoplankton communities: Effects of nutrient changes and CO{sub 2} sources. Renewal year two report
Impacts of land-use activities on wetland ecosystems, their resiliency, restoration, and related topics continue to be front-page issues for environmental planners, conservation groups, and government agencies. Among the abundant wetland systems within the United States Department of Energy (DOE) Savannah River Site (SRS) are unique aquatic environments known as Carolina bays. Carolina bays represent especially critical habitat areas because they are the only naturally occurring aquatic systems above the floodplain in otherwise dry upland areas. Developing a clear understanding of the functional roles of phytoplankton and their responses to water chemistry is essential if natural ecosystem integrity is to be maintained through Carolina bay conservation and restoration efforts. The main objective of this second renewal year project effort was to determine the primary sources of CO{sub 2} for algal photosynthesis and the CO{sub 2} exchange flows between bottom sediments, water column, and the atmosphere. This objective was designed to quantify a portion of the role that these wetlands play in CO{sub 2} cycling through the actions of decomposition, atmospheric diffusion, and algal photosynthesis. An additional objective was to continue to measure the patterns of phytoplankton community dynamics and changes in water chemistry in Flamingo Bay and Lost Lake for comparison with previous years. The continued population sampling and chemical analyses were designed to evaluate effects of potential nutrient increases resulting from fertilizing in Lost Lake restoration efforts.
