Rhizocephalan Parasites Of Mud Crabs In South Carolina Estuaries, Erin Burnette
Rhizocephalan Parasites Of Mud Crabs In South Carolina Estuaries, Erin Burnette
Honors Theses
Rhizocephalan parasites often infect commercially important crustacean species such as the blue crab (Callinectes sapidus). In this experiment, the prevalence of rhizocephalan parasites was determined by sampling mud crabs (Panopeus herbstii) in three different locations; Huntington Beach State Park, Waites Island, and Murrells Inlet. Crabs were determined to be parasitized by the presence of an externae extruding from their apron. Unparasitized crabs were also collected to serve as a control group. The externa were removed and DNA extractions were performed. Polymerase chain reactions (PCR) were done to prove whether the crabs were parasitized by Loxothylacus texanus or Loxothylacus panopaei. Results …
Preferential Fish Consumption Based On Omega-3 Fatty Acids And Mercury Concentrations For Maximum Health Benefits, Katrina Smith
Preferential Fish Consumption Based On Omega-3 Fatty Acids And Mercury Concentrations For Maximum Health Benefits, Katrina Smith
Honors Theses
The regular consumption of seafood offers a variety of protective effects, including the reduction of the risk of cardiovascular disease and stroke, due to the presence of omega-3 fatty acids in fish. These protective effects may be diminished by the contamination of seafood by mercury. Mercury increases the risk of cardiovascular problems and impedes neurological development. The objective of this project was to determine the fish species that are appropriate for consumption based on low levels of mercury and recommended intake levels of omega-3 fatty acids. Species that are high in omega-3s and low in mercury include salmon, trout and …
Catalytic Decomposition Of Peroxynitrite And Superoxide By Nafion Films Modified With Iron And Manganese Porphyrin, Amanda Stull, Victor Sarpong
Catalytic Decomposition Of Peroxynitrite And Superoxide By Nafion Films Modified With Iron And Manganese Porphyrin, Amanda Stull, Victor Sarpong
Honors Theses
Nafion films alone and modified with inert electrolytes and metalloporphyrins were tested in their effectiveness of decomposition of aqueous peroxynitrite (PN) and superoxide. Films that were modified with a cationic manganese porphyrin, which has been shown to be responsible for catalytic decomposition of superoxide ion, were found to be most effective. Peroxynitrite was generated in solution by the decomposition of 3-morpholinosydnonimime (SIN-1) that generates nitric oxide and superoxide ion, which rapidly combine to form peroxynitrite. The tyrosine analogue 4-hydroxyphenylacetic (4-HPA) was used to trap the PN in pH 7.00 PBS buffer and was its nitrated product was detected by observing …
The Effect Of A Phytoplankton Maximum On The Trophic Food Chain Of The Bottlenose Dolphin (Tursiops Truncatus) In North Inlet, South Carolina., Lindsay Michael Stang
The Effect Of A Phytoplankton Maximum On The Trophic Food Chain Of The Bottlenose Dolphin (Tursiops Truncatus) In North Inlet, South Carolina., Lindsay Michael Stang
Honors Theses
Jones Creek, part of North Inlet-Winyah Bay, South Carolina, is known to have a chlorophyll a maximum that exists during low tide. The goal of this study was to determine if an increase in phytoplankton, demonstrated by chlorophyll a levels, would lead to an increase in zooplankton, fish, and bottlenose dolphins in the area. Sampling for chlorophyll a concentrations, zooplankton and dolphin densities occurred in fall of 2008. Based on the samples obtained, as chlorophyll a concentrations increased at low tide, zooplankton densities decreased. Dolphin density plots showed an increased density in Jones Creek during low tide for spring, summer, …
Effects Of A Spatially And Temporally Predictable Chlorophyll Maximum On Bottlenose Dolphin Distribution In A South Carolina Estuary, Steven W. Thornton
Effects Of A Spatially And Temporally Predictable Chlorophyll Maximum On Bottlenose Dolphin Distribution In A South Carolina Estuary, Steven W. Thornton
Honors Theses
Numerous studies have focused on the complex relationship between phytoplankton and zooplankton in estuarine environments, but few have scrutinized the effects of this connection on organisms in higher trophic levels. This study examined chlorophyll a concentrations and zooplankton densities in North Inlet, South Carolina, a site where a stable chlorophyll a maximum has been documented to exist at low tide, to determine if they influenced the distribution of resident bottlenose dolphins (Tursiops truncatus). We hypothesized that patterns of estuarine circulation in the salt marsh serve to concentrate phytoplankton and zooplankton predictably in time and space, and that these patterns influence …
