The Impacts Of Seasonality And Nutrient Loading On Microcystis Bloom Development In Wall Pond, Alyssa Antolak
The Impacts Of Seasonality And Nutrient Loading On Microcystis Bloom Development In Wall Pond, Alyssa Antolak
Honors Theses
The harmful cyanobacteria Microcystis globally dominates eutrophic freshwater systems. Eutrophication leading to nitrogen and phosphorus loading into aquatic systems is increasing bloom propagation and shifting diatom/dinoflagellate dominated systems to cyanobacteria dominated systems. Understanding seasonal variability and environmental parameters combined with nutrient loading will allow for a better understanding of what factors are influencing Microcystis blooms. Biweekly plankton samples and environmental parameters were collected from Wall Pond from spring 2022-spring 2023. Results show that yearly plankton samples shifted from Microcystis dominated in the early summer to diatom dominated in the late summer-early fall then back to Microcystis dominated in late fall-early …
A Comparison Of Phytoplankton Nutrient Limitation Between The Marsh And Beach Environments Of Waties Island, Sc, Raymond Sgambati, George Boneillo
A Comparison Of Phytoplankton Nutrient Limitation Between The Marsh And Beach Environments Of Waties Island, Sc, Raymond Sgambati, George Boneillo
Honors Theses
The aim of this study was to investigate the differences in nutrient limitation within the beach and marsh environments at Waties Island, SC. Conducting the experiment on Waties Island allowed most physical factors to be held as constant, meaning the marsh and beach environments would serve as the only variables. Experiments were performed in the winter, spring, summer and fall of 2018 to determine temporal changes in limitation to phytoplankton and cyanobacteria growth. Nutrient additions included dissolved inorganic nitrogen (nitrate, nitrite, and ammonium), dissolved organic nitrogen (urea), and phosphate. To test for co-limitation, a nitrate & phosphate treatment was also …
