Effect Of Temperature On Morphology Of The Cardiorespiratory System Of Striped Bass (Morone Saxatilis), Alley E. Permenter

Honors College Theses

Climate change and temperature are two very important topics for the coming future. As climate change projections estimate a 2-3°C increase in water temperatures by the end of the century, the habitats of many aquatic organisms will be affected in more ways than one. Temperature has proven to be an integral part of the driving force that causes physiological, behavioral, and ecological patterns in aquatic organisms. Striped bass (Morone saxatilis) and their responses to changes in water temperature have been a topic of interest due to the fact that the southern populations do not follow their northern counterparts …

Silver Nanoparticle Fate And Accumulation In The Aquatic Food Web Of Stream Microcosms, Stefan J. Petersen

Electronic Theses and Dissertations

Silver nanoparticles (AgNPs) are used in 25% of all nano-enabled products and applied for anti-microbial properties. Silver nanoparticles are discharged into aquatic environments through wastewater discharge, runoff, and chemical spills. Once in aquatic environments silver nanoparticles have the potential to harm aquatic organisms. While the fate of silver nanoparticles in lentic systems has been investigated, limited information is available for the fate of silver nanoparticles in flowing environments. The purpose of this study was to compare the fate of AgNPs following a one-time pulsed application simulating a chemical spill, or small repetitive applications simulating effluent discharge, in artificial stream communities …

Population Viability Analysis For Endangered Roanoke Logperch, James Henry Roberts, Paul L. Angermeier, Gregory B. Anderson

Department of Biology Faculty Publications

A common strategy for recovering endangered species is ensuring that populations exceed the minimum viable population size (MVP), a demographic benchmark that theoretically ensures low long-term extinction risk. One method of establishing MVP is population viability analysis, a modeling technique that simulates population trajectories and forecasts extinction risk based on a series of biological, environmental, and management assumptions. Such models also help identify key uncertainties that have a large influence on extinction risk. We used stochastic count-based simulation models to explore extinction risk, MVP, and the possible benefits of alternative management strategies in populations of Roanoke logperch Percina rex, an …

Parasite Infection Mediates Trait Tradeoffs In Fundulus Heteroclitus, Sarah Dunn

Honors College Theses

To be successful, an animal must eat, grow, and reproduce. With limited resources, there are tradeoffs between these critical life history parameters but the direction of the tradeoffs is largely unknown in a changing environment. To determine whether environmental context affects life-history tradeoffs, I surveyed and quantified investment into reproduction, growth, and a proxy for immunity (parasitism), in the mummichog, Fundulus heteroclitus, a common inhabitant of salt marshes in Georgia. Three salt marsh sites along coastal Georgia (Shellman Bluff, Skidaway Island, and Tybee Island) were selected using a proxy for anthropogenic disturbance (impervious surface), which also fell along a …
