Research

My research is in the fields of aquatic ecology and paleolimnology (history of lake systems). Aquatic ecosystems are a limited and invaluable resource that can be altered by environmental and anthropogenic stressors. The primary focus of my research is to measure biogeochemical (organic matter, nutrients, metals, TC/TN) and ecological (cyanobacteria, algae, macrophytes) parameters in lakes to determine the governing processes that drive ecosystem states.  Typically, I analyze sediment cores to reconstruct lake histories, but I also work with modern limnological techniques.  Projects integrate intensive field research with complimentary laboratory experimentation, photosynthetic pigment analysis and organic matter analysis to examine how paleolimnological techniques can be used to infer ecosystem change as well as forecast future aquatic ecosystem states.

Current Projects:

1.  Historic primary producer changes in Lake Griffin, Florida.  We are measuring photosynthetic pigments, organic matter, nutrients and cyanotoxins in a 3m sediment core collected from Lake Griffin, FL, a eutrophic, shallow lake in central Florida.

2.  Paleolimnology of Georgia’s natural lakes.  We are measuring paleolimnological parameters (photosynthetic pigments, charcoal, nutrients, macrofossils, etc.) in sediment cores collected from the Lake Park, GA area (Georgia’s only area of natural lakes) in order to reconstruct the anthropogenic, environmental and climatic effects on the system throughout the last 10,000 years.

3.  The impacts of fragmentation, land use, and invasive species on the ecology of Lake Seminole, GA.  We are investigating the transport of materials into Lake Seminole from the differing watersheds of the Flint (agricultural) and Chattahoochee (industrial) Rivers.  In addition, we are monitoring the cycling of those materials through the ecosystem, which includes the invasive speces, Hydrilla, Corbicula and Pumacea. Graduate Students: Josh Boston, Chase Patrick

4.  Historic primary producer communities in the Florida Everglades.  We are measuring photosynthetic pigments in several sediment cores from the Florida Everglades to determine nutrient (P) and climatic (hurricanes) impacts on the system’s primary producers throughout the last 200 years.

5.  Holocene biological change in northern Alabama as inferred from a 7000 year old bat guano core.  We are measuring nutrients, metals, charcoal, insect fragments and pollen in a 7000 year old guano core collected from Fern Cave Alabama in order to infer bat colony persistence, terrestrial flora presence and human interactions in and around the cave.
