Population Ecology of Invasive Lionfish (Pterois volitans/miles) in the South Atlantic Bight
… predator that are now established in the Western Atlantic, Caribbean Sea and Gulf of Mexico. Studies that have documented impacts of lionfish suggest they can reduce fish recruitment and native species biomass by up to 80%. Research on lionfish impacts, biology and ecology is heavily focused in …

Inducible Chemical Defenses in Temperate Reef Sponges of the South Atlantic Bight, U.S.A.
… defenses. To investigate if reef sponges in the South Atlantic Bight employ inducible chemical defenses, I tested two predictions with Ircinia campana, I. felix, and Aplysina fulva. First, concentrations of antipredator compounds should covary with the abundance of sponge predators. Second, …

Sponge Community Structure and Anti-Predator Defenses on Temperate Reefs of the South Atlantic Bight
… anti-predator defenses on temperate reefs in the South Atlantic Bight. Significant differences in the distribution of sponge species, sponge densities, and densities of sponge predators were documented across two adjacent reef habitats. Significant differences also occurred in the distribution of …

On the Low-Frequency Current and Temperature Fluctuations Along the Shelf Break in the South Atlantic Bight
… data collected along the shelf edge in the South Atlantic Bight were analyzed using a spectral analysis technique. The power spectra of both alongshore currents and temperatures (upon removal of seasonal trends) in the mid- to lower water column suggest a significant energy peak at 28 days. …

Sessile Invertebrate Colonization on Rocky Outcrops at Gray's Reef National Marine Sanctuary
… and designing effective marine reserves. In the South Atlantic Bight, invertebrate assemblages can differ significantly from one rocky outcrop to another, but the factors driving these differences are not well understood. I tracked community development for fourteen months at four rocky outcrops …

Freshwater Transport on the Continental Shelf of the Southeastern United States
<p>The circulation of water over the shelf of the southeastern United States was examined during the Fall Removal Experiment from late October to early November 1987. A steady state, two-dimensional analytical model of wind and density driven flow was used to study the relative importance of …

Age Validation and Reproductive Biology of Bluefish, <i>Pomatomus saltatrix,</i> Along the East Coast of United States
… compared by sex, year, and between the South Atlantic and Middle Atlantic Bights using likelihood-ratio tests. The estimated Atlantic von Bertalanffy model growth parameters were Linf = 815.3mm ± 15.3, k = 0.311 ± 0.03, t0 = -.301 ± 0.18. Histology, trends in gonadosomatic index, and …

Effects of Sediment on Growth and Survival of Various Juvenile Morphologies of the Scleractinian Cora, Oculina Arbuscula (Verrill)
… sedimentation rates on a hard-bottom reef in the South Atlantic Bight (SAB) off the coast of Georgia, USA and assessed its effects on a conspicuous member of the benthic community: the scleractinian coral, Oculina arbuscula. I addressed the predictions that: 1) inorganic and organic sedimentation …

Seabird foraging in dynamic oceanographic features
… as demonstrated in previous studies in the South Atlantic Bight. Prey availability in Gulf Stream frontal eddies was highest in eddy cold core regions, particularly in those regions close to the Gulf Stream. Taken together, the results of my dissertation: underscore the importance of …

Tidal hydrodynamic response to sea level rise and coastal geomorphology in the Northern Gulf of Mexico

Are Chemical Defenses Allocated within Sponges to Defend Regions Most at Risk to Predator Attack?
The allocation of chemical defenses to regions most at risk to predator attack may provide adequate protection at minimal metabolic cost. This study examined chemical defense allocation within three sponge species from a temperate reef by investigating the predictions that: concentrations of …
