| الوصف: | High levels of nitrate loading to the Mashapaquit Creek and West Falmouth Harbor are causing changes in the composition of primary producers and the amount of annual net primary production (Howes, 2005). While the Quashnet River system experiences some level of anthropogenic nutrient loading from its watershed, nitrate concentrations in the incoming groundwater are not anywhere near as high (Table 1). Microalgal community response to nutrient loading in these two systems was examined with microcosm nutrient enrichment experiments (fertilization with nitrogen, phosphorous, or both) with water sampled along a salinity gradient in the two sites; biomass and dissolved inorganic nutrient concentrations were quantified at the end of a 21 day incubation period in a growth chamber. Phosphorous enriched microcosms failed to produce meaningful outcomes for this experiment but results from the nitrogen enrichments suggest that phytoplankton from the Mashapaquit Creek may have internal stores of nitrate from before they were removed from their natural environment. 1 |
