The Effects Of Human Approach On Sanderling Foraging Behavior, Anne Hobdy, Eric Rosch
Honors Theses
During low tide, sanderlings (Calidris alba) forage on small invertebrates in the sand of the intertidal zone. As a result, these common shorebirds frequently come into contact with humans who visit the beaches for a variety of activities, such as fishing or jogging. Here, the effects of three different approach types (undisturbed, passive, and aggressive) on sanderling foraging behavior were examined to help understand how human activities may be affecting their ability to search for food. At two local beaches, locomotory rate was recorded in addition to obvious changes in initial behavior. Treatments were defined as follows: 1) …
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 …
