Developing Rapid Indicators To Detect Micropollutants In Coastal Blackwater Rivers In South Carolina, Lydia Winn
Developing Rapid Indicators To Detect Micropollutants In Coastal Blackwater Rivers In South Carolina, Lydia Winn
All Theses
Micropollutants in water sources are found in higher concentrations in areas with high levels of urban and agricultural land. These pollutants can be introduced into water sources during storms and rain events, through water treatment outputs, and commercial or residential waste. These events increase the levels of both nutrients and micropollutants in these water sources. With increasing levels of micropollutants in rivers, this study’s goal was to develop an alternative detection method or an indicator test for the levels of micropollutants in water. We first proposed the use of amicrobial fuel cell (MFCs) operating as a biosensor could be utilized …
Impacts Of Urbanization On Pollination Success For Common Milkweed (Asclepias Syriaca), David Rockow
Impacts Of Urbanization On Pollination Success For Common Milkweed (Asclepias Syriaca), David Rockow
Electronic Theses and Dissertations
Urbanization is among the greatest threats to biodiversity on the planet, and is projected to increase in magnitude in coming years. This growing threat makes it important to better understand how urbanization may impact vital ecosystem services, such as pollination. Studies on the impact of urbanization on pollination vary wildly in their findings. This study analyzed multiple aspects of pollination success in common milkweed populations varying in urbanization level, including insect community composition, pollen removal/deposition, and fruit/seed production. By analyzing multiple pollination aspects we can determine the overall mechanism in which urbanization instills on the entire pollination process. Overall, urbanization …
Population Physiology, Demography, And Genetics Of Side-Blotched Lizards (Uta Stansburiana) Residing In Urban And Natural Environments, Spencer B. Hudson
Population Physiology, Demography, And Genetics Of Side-Blotched Lizards (Uta Stansburiana) Residing In Urban And Natural Environments, Spencer B. Hudson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wildlife populations across the globe are poised to lose their natural habitat to urbanization, yet there is limited information on how different species handle living in cities. Animals in urban environments are often susceptible to novel stressors, which can threaten their individual health and population viability. The physiological characteristics of animals, such as those related to metabolic hormones, oxidative stress, and immunity, are expected to be important for survival in this context. If so, animals persisting in urban areas may demonstrate physiological differences from their natural counterparts, perhaps due to evolutionary change. These potential outcomes have been documented in birds …
Determining How Anthropogenic Change Filters Biological Communities And How Species Modify Their Traits In Response To Urbanization, Kristopher Warren Row
Determining How Anthropogenic Change Filters Biological Communities And How Species Modify Their Traits In Response To Urbanization, Kristopher Warren Row
Biology Dissertations
Humans are significantly altering the environment at an alarming pace, leading to a reduction in species diversity. This transformation has created modified habitats where some species struggle to survive, while a few others not only manage to survive but thrive. One of the most drastic forms of habitat modification is urbanization, which is spreading worldwide and contributing to the decline of biodiversity. Urbanization has given rise to urban-tolerant species that differ ecologically from species that avoid urban areas across various niche dimensions. These urban-tolerant species must adapt to changes in food sources, microhabitat conditions, and alterations in physical habitat structures. …
The City Blues Of An Iridescent Canary: Physiological, Behavioral, And Developmental Impacts Of Lead (Pb) On Songbirds Along An Urban-To-Rural Gradient, Michelle Ross
Master of Science in Integrative Biology Theses
Urbanization is rapidly changing the environment and creating new challenges in the lives of animals across the globe. Anthropogenic contaminants found commonly in old construction materials—including heavy metals like lead— persist within the environment for prolonged periods of time and present a widespread problem for all who live near contaminated areas. Despite the phase-out of lead usage, it continues to threaten the health of all organisms but especially those from urban areas where historical lead use was more common. Currently, the sub-lethal effects of lead on wildlife are not well understood, though lead is known to affect physiology and behavior …
Neonate Atlantic Sharpnose Shark (Rhizoprionodon Terraenovae) Relative Abundance And Body Condition In Two South Carolina Estuaries Varying In Urbanization, Rileigh E. Hawk
Electronic Theses and Dissertations
Urbanization near estuaries has been shown to affect the growth and survival of juvenile sharks using the system as a nursery. North Inlet and Murrells Inlet, South Carolina, are similarly-sized, tidally-dominated, bar-built estuaries with extensive Sporobolus-lined tidal creeks but differ in degree of human impact. Previously, Murrells Inlet was shown to have a lower abundance and diversity of large sharks than North Inlet and Atlantic Sharpnose Sharks (Rhizoprionodon terraenovae) were shown to use North Inlet as a primary nursery. To examine potential differences in neonate shark abundance and growth between a developed estuary, Murrells Inlet, and a protected estuary, North …
Plastic Accumulation In Stormwater Pond Soils Across Socioeconomic And Watershed Development Gradients, Carley Defillips
Plastic Accumulation In Stormwater Pond Soils Across Socioeconomic And Watershed Development Gradients, Carley Defillips
USF Tampa Graduate Theses and Dissertations
Stormwater runoff is a major vector transporting pollution along the land-to-sea continuum, with the mobilization of nutrient pollution in stormwater runoff being well documented. Although plastic is a pollutant of growing concern, few studies have focused on the potential role stormwater ponds play in mediating plastic transport. This study uses a combination of watershed development and socioeconomic variables to characterize plastic pollution patterns in dry stormwater ponds (those not inundated outside of times of major rainfall) at a watershed scale. Each pond basin was sampled for plastics embedded in the soil and laying on the pond surface using a systematic …
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Theses and Dissertations (Comprehensive)
The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …
