The Effects Of Temperature And Oxygen Availability On Aerobic Performance In Three Coastal Shark Species; Squalus Acanthias, Carcharhinus Limbatus, And Carcharhinus Leucas, Alyssa M. Andres
USF Tampa Graduate Theses and Dissertations
Anthropogenically driven climate changes are altering marine habitats globally. Rising sea surface temperatures and coastal eutrophication, arising from global warming and coastal nutrient loading, have resulted in progressive ocean deoxygenation. This may restrict available habitat of marine organisms as studies suggest that the balance between metabolic oxygen demand and environmental supply plays an important role in limiting viable habitat and species fitness. As ectothermic predators, with temperature-dependent metabolism and high metabolic demands, coastal shark species may be susceptible to shifts in ocean temperature and oxygen. Such environmental changes may alter metabolic performance and ultimately success and survival within shark habitat. …
Development Of A High Throughput, Whole Organism Assay For Studying Metabolic Capacity In Crassostrea Virginica, Avuntaura Gulledge
Development Of A High Throughput, Whole Organism Assay For Studying Metabolic Capacity In Crassostrea Virginica, Avuntaura Gulledge
Honors College
Genetic improvement of commercial lines has been a key component in the increased production of eastern oysters (Crassostrea virginica). One form of genetic improvement, induced triploidy, is commonly used to produce sterile oysters with faster growth and higher meat quality. However, the details of the physiological advantage provided by triploidy are poorly understood. Whole animal respiration is an important indicator of an individual’s capacity to meet increased energetic demands for growth and stress response. I have developed an assay for the Agilent’s XFe96 Extracellular Flux Analyzer to measure metabolic capacity (i.e., rates of basal, maximal, mitochondrial, and non-mitochondrial oxygen consumption) …
Relating Metabolic Phenotypes To Movement Behavior In Brook Trout, Jacob E. Bowman
Relating Metabolic Phenotypes To Movement Behavior In Brook Trout, Jacob E. Bowman
All NMU Master's Theses
Brook trout movement-related life history strategies vary considerably and range from individuals that stay within the same 100 meters their entire life to individuals that are potamodromous or anadromous. Potential drivers of movement life histories have been the subject of much research in fish, with genetic subpopulation explanations often failing to explain the phenomenon. Metabolic phenotypes have been suggested as a possible driver for expression of different movement life histories. I investigated if metabolic phenotypes are related to movement strategies within a population of brook trout (Salvelinus fontinalis) in Unnamed Creek, a tributary to the Rock River, Alger …
