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 …
Striped Blenny (Chasmodes Bosquianus) Presence And Behavior Between Sunrise And Sunset At Oyster Landing, South Carolina, Madeline Schuetze
Striped Blenny (Chasmodes Bosquianus) Presence And Behavior Between Sunrise And Sunset At Oyster Landing, South Carolina, Madeline Schuetze
Honors Theses
Lunar and diel cycles of fishes can help to interpret their behaviors during their reproductive season. Temperate estuaries are used by many benthic fishes for shelter and reproduction. This study examined the behavior and presence of striped blennies (Chasmodes bosquianus) during diel and lunar cycles. PVC pipe shelters were placed to mimic oyster shell nests, a natural habitat for blennies, and cameras were placed to monitor these shelters in April, May, and June 2022, during the striped blenny reproductive period. Video footage was reviewed and analyzed for the presence and behavior of both male and female blennies. Male presence …
Are Rising Seas Pushing Ghost Crabs Out Of Their Comfort Zone?, Finn Gillette
Are Rising Seas Pushing Ghost Crabs Out Of Their Comfort Zone?, Finn Gillette
Honors Theses
Ghost crabs (Ocypode quadrata) can be found on sandy beaches bordering the western Atlantic Ocean. These semiterrestrial crustaceans are often found between the swash zone and the dunes on beaches. Dunes are critical refuges for ghost crabs during storms and extreme tide events. This makes them a useful indicator species for monitoring the effects of global warming-induced sea level rise on beach biota, as their distribution patterns among beach zones may correlate with shifts found in other species. Beach surveys conducted from 2015 onward assessed the population density of ghost crabs on beaches of Horry and Georgetown counties …
Microplastic Accumulation In The Digestive Tract Of Young-Of-Year Atlantic Sharpnose Sharks (Rhizoprionodon Terraenovae) In The Grand Strand, Sc, Andrew Curtis Sitlinger
Microplastic Accumulation In The Digestive Tract Of Young-Of-Year Atlantic Sharpnose Sharks (Rhizoprionodon Terraenovae) In The Grand Strand, Sc, Andrew Curtis Sitlinger
Electronic Theses and Dissertations
This study focused on the presence and accumulation of microplastic fibers in the digestive tract and livers of young-of-year Atlantic Sharpnose Sharks (Rhizopriondon terraenovae) from two sampling locations along the Grand Strand of South Carolina. R. terraenovae is a small, mesopredatory elasmobranch found abundantly along northwestern Atlantic Ocean coastlines. Thirty specimens of R. terraenovae were collected from May through August of 2020. Microplastics were found in all specimens. A total of 672 plastic particles were identified over the course of the study, with an average of 22.4 ± 10.5 (SD) plastics per specimen. The majority of the plastics were classified …
The Influence Of Bottom Type And Water Column Stratification On Reef Fish Community Structure At Gray’S Reef National Marine Sanctuary, Bridget Campbell
The Influence Of Bottom Type And Water Column Stratification On Reef Fish Community Structure At Gray’S Reef National Marine Sanctuary, Bridget Campbell
Honors Theses
Understanding the physical and oceanographic differences across reef habitats can help researchers assess how those differences influence fish distribution and community structure, which leads to a better understanding of what a healthy reef system looks like. The traditional methods used to assess fish communities on temperate reefs are limited and often focus solely on either the reef structure or water column conditions alone. An assessment of both data sets yields a more complete understanding of the ecosystem as a whole. In this study, Gray’s Reef National Marine Sanctuary (GRNMS) was surveyed both inside and outside a Marine Protected Area (MPA) …
Shark Diversity And Relative Abundance At Myrtle Beach, Sc Fishing Piers, Lynsey E. Isner
Shark Diversity And Relative Abundance At Myrtle Beach, Sc Fishing Piers, Lynsey E. Isner
Honors Theses
Sharks are frequently observed at fishing piers (Barwick et al. 2004; Martin et al. 2019). These piers offer structural habitats for shark prey items, such as smaller fish and invertebrates, which can attract sharks to piers (Barwick et al. 2004; Heupel 2005). Additionally, fishers often clean their catch and discard entrails at the pier, which also may attract sharks (Martin et al. 2019). Moreover, other factors could play a role in attracting sharks to piers. These include water quality parameters, like salinity and temperature, and the physical characteristics of the pier (Ulrich et al. 2007; Castro 1996; Heupel 2005).
Microfiber Concentrations In Sand From Nesting Sea Turtle Beaches In Costa Rica, South Carolina, And Florida., Kaylin Leroy, George Boneillo
Microfiber Concentrations In Sand From Nesting Sea Turtle Beaches In Costa Rica, South Carolina, And Florida., Kaylin Leroy, George Boneillo
Honors Theses
Microplastics are an increasing threat to marine environments and the organisms that inhabit them. Since plastic pollution in the ocean is prominent throughout the globe, microplastic is washing ashore, affecting important sea turtle nesting sites. This study quantified microfibers in the sand of various sea turtle nesting sites around the world. Sand samples were collected in Myrtle Beach (South Carolina), Destin (Florida) and the Pacuare Reserve (Costa Rica). The microfibers were retrieved using a super saline solution and then filtered under a hood. Filters were then counted using microscopy. Microfibers were found at every sampling site, with the lowest surface …
Potential Arm Preference Within Starfish Species Including Asterias Vulgaris And Luidia Clathrata: A Study And Summary, Rebecca Jones, Young Robert
Potential Arm Preference Within Starfish Species Including Asterias Vulgaris And Luidia Clathrata: A Study And Summary, Rebecca Jones, Young Robert
Honors Theses
Foraging arm preference was tested in two species of starfish: Asterias vulgaris and Luidia clathrata. No evidence was found for a species-wide preference or for a preference by individual sea stars, but trials were impacted by illness and resulting low sample size.
Pre-Juvenile Naked Goby (Gobiosoma Bosc) Age And Growth, Annamaria Deitz, Juliana Harding
Pre-Juvenile Naked Goby (Gobiosoma Bosc) Age And Growth, Annamaria Deitz, Juliana Harding
Honors Theses
Due to the abundance of larval naked gobies, Gobiosoma bosc, within the estuarine ichthyoplankton, it is important to understand their age and growth. Naked gobies are a largely distributed, both geographically and within an estuary, small, benthic fish species. There are 3 pairs of otoliths, calcium carbonate structures within the ear canal, that detect vibrations and record the age of the fish, both daily and annually. Using laboratory-reared gobies of a known age (Tremont et al. 2015), daily signatures on the sagittal otoliths were first validated to be daily, then a growth curve for the wild caught larvae was …
Microplastics In Fiddler Crabs (Genus Uca), Gabrielle Forbes, Eric Rosch
Microplastics In Fiddler Crabs (Genus Uca), Gabrielle Forbes, Eric Rosch
Honors Theses
Microplastics, as defined by NOAA, are small plastic pieces less than five millimeters long, which cannot be seen with the naked eye. The production of plastic products and plastic use has exponentially increased since the start of plastic usage. Consequently, the amount of plastic waste has also increased greatly. Plastic waste that has been thrown out by humans into the environment breaks down into microscopic pieces, causing harm to organisms that live there. The purpose of this study was to see if there were microplastics passing through fiddler crabs (genus Uca), collected from the marsh at Waties Island, SC. Fecal …
The Effects Of Human Approach On Sanderling Foraging Behavior, Anne Hobdy, Eric Rosch
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 …
