Summary: The goal of this work is to investigate growth and production dynamics of the most dominant salt marsh grass in the southeastern United States, Spartina alterniflora, including documenting the non-structural carbohydrates pool and presenting translocated biomass between above- and below-ground tissues in S. alterniflora during several phenological periods.

Savannah, Ga. – Tiny pieces of plastic are so pervasive in Georgia’s coastal waters, researchers estimate there are more than a trillion microplastic particles and fibers in the top foot of the state’s inshore waterways.  The issue of microplastics in coastal waters and what, if anything, can be done about them will be the focus of a special Evening @ Skidaway program on Thursday, Nov. 16, in the McGowan Library on the University of Georgia…

The influence of aerosol particles on clouds remains one of the largest uncertainties in accurately predicting the Earth’s energy balance in a changing climate system. The size and chemical composition of aerosol particles affects their radiative properties and ability to grow into cloud droplets, thus influencing the properties and lifetimes of cloud. Recent studies suggest that the presence of surface-active organics (surfactants) in these…

Many host-associated bacteria use pheromone-signaling (PS) systems to coordinate group behaviors.  Such signaling requires high cell density, and is often referred to as “quorum sensing”.  However, a high cell density “quorum” may be necessary but not sufficient to induce a behavior. Our understanding of the light-organ symbiosis between the bioluminescent bacterium Vibrio fischeri and the Hawaiian bobtail squid Euprymna scolopes suggests that…

Peat mosses of the genus Sphagnum play a major role in global carbon storage and predominate over photosynthetic production in many northern peatland ecosystems, which are currently being subjected to some of the most rapid climate change on Earth. The objectives of this research are 1.) to investigate the role of the Sphagnum phytobiome (plant host + constituent microbiome + environment) in regulating the carbon and nutrient cycles of peatland…
