Response Of Natural Estuarine Algal Communities To Nitrogen Additions, Christopher Schweitzer
OES Theses and Dissertations
Coastal eutrophication resulting from nutrient over-enrichment plagues coastal waterways worldwide. In addition to dissolved inorganic N, many marine microbes, including phytoplankton, have the capacity to use certain dissolved organic nitrogen (DON) compounds. However, while we know that many specific DON compounds are labile, the bulk of the DON pool in nature is uncharacterized. The bioavailability of DON to estuarine microbes currently remains unclear.
It is becoming evident that natural phytoplankton assemblages in estuarine waters are capable of using both inorganic and organic N compounds for growth, both of which are present in anthropogenic point and non-point source discharges. Methods for …
