A Multibiomarker Analysis Of Pollutant Effects On Atlantic Stingray Populations In Florida’S St. Johns River, John Whalen
A Multibiomarker Analysis Of Pollutant Effects On Atlantic Stingray Populations In Florida’S St. Johns River, John Whalen
UNF Graduate Theses and Dissertations
The goal of this study was to examine the potential health effects of organochlorine (OC) and polycyclic aromatic hydrocarbon (PAH) exposure on Atlantic stingray populations in Florida’s St. Johns River (SJR). Special emphasis was placed on identifying OC- and/or PAH-related effects in stingrays from areas of the lower (LSJR) and middle (MSJR) basins shown to possess elevated levels of these compounds, as well as characterizing baseline levels of pollutant exposure in the SJR shipping channel, which may be subjected to dredging in the near future, potentially resuspending and redistributing contaminated sediments and increasing pollutant-associated effects. To accomplish this, we measured …

Effects Of The Deepwater Horizon Oil Spill On Deep Sea Fishes, Arianne Ella Leary
UNF Graduate Theses and Dissertations
The Deepwater Horizon Oil Spill (DWH) released about 4.4 million barrels of crude oil into the Gulf of Mexico (GOM), making it one of the largest oil spills in U.S. history. Additionally, the depth of the spill (i.e., 1500 meters) created a unique research opportunity because most oil spills occur at the surface and affect coastal rather than deepwater habitats. Polycyclic aromatic hydrocarbons (PAHs) are the most toxic components of oil, and are often the focus of oil exposure studies. PAHs are quickly metabolized by vertebrates; therefore, indicators of biological responses to PAH exposure (PAH “biomarkers”) such as the levels …
The Performance Of Simple Artificial Floating Wetland Communities And Their Effects On Aquatic Nutrient Levels And Algal Abundance, Bradley L. Sleeth
The Performance Of Simple Artificial Floating Wetland Communities And Their Effects On Aquatic Nutrient Levels And Algal Abundance, Bradley L. Sleeth
UNF Graduate Theses and Dissertations
Harmful algal blooms are exponential increases in autotrophic microorganisms that proliferate in such a way that the surrounding environment, the local economy and the health of regional populations are negatively affected. Among the causes of these blooms are anthropogenic inputs of excess nitrogen and phosphorus into the environment through overfertilization. Floating treatment wetlands (FTW) have emerged as a novel method of reducing the negative impacts of these nutrient inputs by using artificial rafts to float normally emergent wetland plants on the surface of water bodies to assimilate excess nutrients. Because their use is so new, only limited research has been …
