Abstract: <p>Aquatic contaminant mobility and biological availability is strongly governed by the complexation of organic and inorganic ligands. Dissolved organic matter (DOM) is a complex, heterogeneous mixture of organic acids, amino acids, lipids, carbohydrates and polyphenols that vary in composition and can complex to dissolved metals thereby altering their fate in aquatic systems. The research… more Full Text: Molecular Composition of Dissolved Organic Matter Controls Metal Speciation and Microbial Uptake A dissertation submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the faculty …

Abstract: <p>Contemporary evolution has the potential to help limit the biological impact of rapidly changing climates, however it remains unclear whether wild populations can respond quickly enough for such adaptations to be effective. In this thesis, I used the introduction of native North American Pumpkinseed (Lepomis gibbosus) into the milder climate of Europe over 140 years ago, as a '… more Full Text: CONTEMPORARY ADAPTIVE SHIFTS IN THE PHYSIOLOGY AND LIFE HISTORY OF PUMPKINSEED (LEPOMIS GIBBOSUS) INTRODUCED INTO A WARM CLIMATE.

Abstract: <p>Recent declines in North American shorebird populations could be linked to habitat loss on the non-breeding grounds. Sea-level rise and increased frequency of coastal storms are causing significant erosion of barrier islands, thereby threatening shorebirds who rely on shoreline habitats for foraging. I conducted shorebird surveys on Bulls Island, South Carolina in the winters of 2018 and… more Full Text: SHOREBIRD HABITAT USE AND FORAGING ECOLOGY ON BULLS ISLAND, SOUTH CAROLINA DURING THE NON-BREEDING SEASON A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty …

Abstract: <p>Many rare and elusive species have low detection probabilities, thereby imposing unique challenges to monitoring and conservation. Here, we assess the detection probability of the Eastern Massasauga (Sistrurus catenatus) in contrast to a more common and conspicuous species, the Eastern Gartersnake (Thamnophis sirtalis). We found that patterns of detection probability differed between… more Full Text: A multi-faceted approach to evaluating the detection probability of an elusive snake (Sistrurus catenatus) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirement for the Degree of Master of Science in the Faculty …
