Earth harbors vast microbial genetic diversity, yet AI-driven functional prediction remains challenging due to underrepresentation in functional reference databases and s[...]

Organic matter (OM) is a key component of local and global carbon cycles, serving as sources of carbon, nutrients and energy for aquatic ecosystems. Despite extensive eff[...]

The shorelines of Cockspur Island, GA are constantly responding to natural and anthropogenic forces. In the fall of 2015, dredge spoil was placed on the north shore to pr[...]

This study used ocean observations, 16 rRNA, and taxonomic insights to understand the relationships between meltwater-modified ocean circulation, iron supply, and pelagic[...]

A high-frequency (67 kHz) acoustical scintillation experiment was carrier out in the northern entrance to Hood Canal, Puget Sound, WA. This experiment made use of a 4-tra[...]

Molecular biomarkers were first used in fossil fuel geochemistry, marking the beginning of the organic geochemistry field, but soon their utilization expanded to environm[...]

The degradation of lignin-related aromatic compounds is an important ecological process in the highly productive salt marshes of the southeastern U. S., yet little is kno[...]

The interactions of dissimilatory processes were studied in organic carbon rich extreme environments, on the basis of geochemical signatures, molecular microbiology, and [...]

Prochlorococcus and Synechococcus are ubiquitous marine icocyanobacteria that contribute significantly to oceanic primary production. The tightly phased patterns of cellg[...]

A cyanobacterium of the genus Cyanobium is found in alkaline hypersaline Mono Lake,California. I have studied its spatial and temporal distribution using epifluorescence [...]

Spartina alterniflora decomposition is an important route for carbon transfer to estuarine detrital food webs. The two major microbial groups of decomposers are fungi and[...]

Polyamines are a group of short-chain aliphatic compounds containing multiple primary or secondary amine groups. They are ubiquitous in aquatic environments with concentr[...]

The Continuous Sediment Sampling System (CS3), a unique, rapid seafloor sediment sampling system developed at The University of Georgias Center for Applied Isotope Studie[...]

A study of the Duplin River, a shallow, sinuous, tidal creek which connects the salt marshes of Sapelo Island, on the central Georgia coast, with the waters of Doboy Soun[...]

Spartina alterniflora is a foundation species that plays a disproportionately critical role in salt marshes, as it ameliorates chemical and physical stress to other plant[...]

I examined the response of a salt marsh food web to nutrients, and spatial variation in this response, at 19 sites on the Georgia coast. In fertilized treatments, Spartin[...]

I developed a spatially explicit model of Thalassia testudinum growth and vegetative propagation in Florida Bay. Thalassia is an ecologically important species in terms [...]

Rates of polar glacial melting are accelerating with rising global temperatures; these increasingly large freshwater fluxes impact coastal marine ecosystems. The meltwate[...]

In winter 2002, portions of the salt marshes of coastal Georgia began experiencing dieback, affecting both Spartina alterniflora and Juncus roemerianus. During the summer[...]

Lignin biomarkers and their stable-carbon isotopic compositions have been used to detect vascular plant inputs in marine sediments, as well as to quantify the relative co[...]

Phytoplankton-produced lipid biomarkers and their compound-specific stable carbon isotopic compositions have been widely used to study organic carbon cycling and paleocea[...]

Ascomycetous fungi play a crucial role in the decomposition of salt marsh vegetation. The first part of this research used molecular methods to examine whether physical [...]

The adult mangrove tree crab, Aratus pisonii, is responsible for significant portions of leaf herbivory in mangrove forests. Using the mixing model software, IsoSource, w[...]
