Physiological And Biochemical Thermal Stress Conditions Of The Ribbed Mussel, Geukensia Demissa, From Exposed And Less Exposed Areas In The Intertidal Salt Marsh On Tybee Island, Georgia., Jody E. Erber Apr 2022

Physiological And Biochemical Thermal Stress Conditions Of The Ribbed Mussel, Geukensia Demissa, From Exposed And Less Exposed Areas In The Intertidal Salt Marsh On Tybee Island, Georgia., Jody E. Erber

Honors College Theses

Geukensia demissa, the ribbed mussel, is a keystone species of Georgia’s coastline that is at risk of experiencing detrimental thermal stress due to climate change. G. demissa interacts positively with a species of salt marsh cordgrass, Spartina alterniflora. Mussels form aggregates beneath salt marsh cordgrass stems where they are shaded and less exposed to sun rays. However, some mussels end up in areas which lack cordgrass and are directly exposed to sun rays. Body temperatures of mussels from exposed areas were found to be higher than mussels from less exposed areas. Thermal stress levels of mussels can be …


Wetland Biogeochemical Responses To Predicted Climate Change Scenarios, Angela R. Shaffer Jan 2019

Wetland Biogeochemical Responses To Predicted Climate Change Scenarios, Angela R. Shaffer

Electronic Theses and Dissertations

Wetlands are one of the world's largest known carbon sinks while comprising only a small amount of the Earth's surface. However, the amount of carbon sequestered by wetlands is shrinking as droughts and human disturbance increases. Carbon in wetlands is stored through the contrast of decomposition and sedimentation of organic matter and absorption of CO2 from the atmosphere by soil microbes. Understanding how changing hydrological regimes and increased wildfires will affect wetland soil and microbial processes is important in the face of predicted climate change for future wetland conservation practices. Specifically, I seek to understand the response of southeastern …
