Use Of Space By Urban Loggerhead Shrikes (Lanius Ludovicianus) As A Window Into Habitat Suitability, Katie A. Maddox, Christopher E. Hill
Use Of Space By Urban Loggerhead Shrikes (Lanius Ludovicianus) As A Window Into Habitat Suitability, Katie A. Maddox, Christopher E. Hill
Biology
Wild animals in urban environments face new challenges that may change how they use space and, at the same time, how they use space provides clues to suitability of habitat: bird territories in desirable areas tend to be smaller and populations denser. Loggerhead Shrikes (Lanius ludovicianus), historically associated with shortgrass habitats such as pasture and shrub steppe, occur widely in urban areas of the southeastern United States. For a complete picture of shrike use of space in urban spaces, we present three measures for a population inhabiting urban areas of Horry County, South Carolina: population density, home range size, and …
Loggerhead Shrike Detectability And Occurrence In Coastal South Carolina Urban Areas, Michelle Krauser
Loggerhead Shrike Detectability And Occurrence In Coastal South Carolina Urban Areas, Michelle Krauser
Electronic Theses and Dissertations
Grassland birds, such as the loggerhead shrike (Lanius ludovicianus), are threatened by extensive land-use change, including urbanization. Loggerhead shrikes have been declining since the early 1900s and are rare or extirpated in portions of their former range. Obtaining reliable population estimates of loggerhead shrikes is important to identify demographic trends and ensure conservation decisions are based on an accurate assessment of their current status. Imperfect detection, or the inability to detect every shrike during a survey, can result in biased population estimates. Estimating detection probability is labor-intensive and requires assumptions that are difficult to satisfy in most field studies. Understanding …

Use Of First Pelvic, Second Pelvic, And Fourth Anal Rays For Estimating Age Of Muskellunge (Esox Masquinongy), Marinda R. Cornett
Use Of First Pelvic, Second Pelvic, And Fourth Anal Rays For Estimating Age Of Muskellunge (Esox Masquinongy), Marinda R. Cornett
Honors Theses
While cleithra are the most popularly used calcified structure used to estimate age of Muskellunge (Esox masquinongy), the use of fin rays as an age estimation structure has been investigated as a nonlethal alternative. My objectives were to: (1) to compare the accuracy and precision of estimating age using first pelvic, second pelvic, and fourth anal rays from 46 known age Muskellunge and (2) to analyze a larger sample (n = 120) of fourth anal rays to estimate age. Ages were estimated blindly by three readers independently from all available structures. Different analyses of precision and accuracy had conflicting results, …
An Examination Of Plant Community Composition In Six Carolina Bays On The Coastal Plain Of South Carolina, Katherine L. Altman-Goff
An Examination Of Plant Community Composition In Six Carolina Bays On The Coastal Plain Of South Carolina, Katherine L. Altman-Goff
Electronic Theses and Dissertations
Historically high rates of human impact and recent Supreme Court cases, which have affected the regulation of geographically isolated wetlands in the United States, suggest that Carolina bays may be at high risk of human impacts in the future. Conservation efforts should be established based on applied ecological data and, if regulations by state and federal agencies are unable to conserve Carolina bay wetlands, it may be important to prioritize individual bays for preservation on protected lands. I examined plant community composition, diversity, richness, and rarity and soil parameters in six Carolina bays across South Carolina, using a replicated ecological …
A Comparison Of Whole Body Mercury Concentrations Of Mummichogs (Fundulus Heteroclitus) And Atlantic Silversides (Menidia Menidia), Daniel P. Ferons
A Comparison Of Whole Body Mercury Concentrations Of Mummichogs (Fundulus Heteroclitus) And Atlantic Silversides (Menidia Menidia), Daniel P. Ferons
Electronic Theses and Dissertations
Few studies have focused on mercury cycling within salt marsh estuaries. Mummichogs (Fundulus heteroclitus) and Atlantic silversides (Menidia menidia) are two species of forage fish that live year round in South Carolina salt marshes. During high tide, mummichogs feed from the water column, sediment, and off of smooth cordgrass while Atlantic silversides prey upon zooplankton. In this study, total and methyl mercury within mummichogs and Atlantic silversides from Dunn Sound, SC were quantified and compared over four seasons throughout 2014. Gut contents were also quantified and compared to determine if there was a dietary impact on the concentrations of total …
Dissolved Nutrient Ratios And Concentrations Affect Fungal Reproduction And Community Structure Associated With Submerged Leaf Litter And Wood, Jennifer Fitzgerald
Dissolved Nutrient Ratios And Concentrations Affect Fungal Reproduction And Community Structure Associated With Submerged Leaf Litter And Wood, Jennifer Fitzgerald
Electronic Theses and Dissertations
Litter-associated fungi are important intermediaries in carbon and energy flow in streams. They can obtain nitrogen (N) and phosphorus (P) from both the substrate and the water column. I tested the effects of dissolved nutrients (dissolved inorganic nitrogen (DIN) 40-975 µg/L, soluble reactive phosphorus (SRP) 2-135 µg/L, N:P ratios 2:1, 16:1, 128:1) on fungi associated with leaf litter (maple and rhododendron) and wood in streamside channels at Coweeta Long Term Ecological Research site, North Carolina. This study addressed two main questions: (1) will fungal reproduction (sporulation rate of aquatic hyphomycetes) peak at a dissolved N:P ratio similar to nutrient stoichiometry …
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 …
