The primary goal of this dissertation was to explore the use of stable isotope analysis as a tool to understand how energy flows at several layers of biological organization from the individual to the ecosystem level. With the exception...
Low oxygen conditions in the water column or hypoxia occur in estuaries and impact more than just the obvious commercially important species. Copepods are an important link in the food web and the influence of hypoxia upon them is...
The Impacts of Macrobenthos on the Rates and Pathways of Organic Matter Mineralization in Two Coastal Marine Ecosystems of the Southeastern United States
Coastal ecosystems are among the most productive in the world, and they serve as an invaluable resource to society. Despite many decades of biogeochemical research in the coastal zone, carbon and nutrient budgets remain uncertain largely...
Ch 1: This study provides the first long term data set on coastal oxygen dynamics in the northeastern Gulf of Mexico (NEGOM), located about 600 km east of the large hypoxic zone that extends west of the Mississippi delta. Oxygen...
To avoid unfavorable seasonal conditions, some species of calanoid copepods produce resting eggs that do not immediately hatch. When buried in the sediment, these eggs can remain viable from weeks to years, and therefore can represent a...
This study addresses the decomposition of dissolved organic carbon (DOC) in highly permeable coastal sand sediments. DOC fluxes from shelf sediments (~180 Tg C yr-1) are significant, roughly equal to the DOC flux from rivers (~200 Tg C...
Mariculture of fish is needed to support our ever growing global population. Copepods are a natural and beneficial source of first feed for many marine fish species, but it can be difficult to hatch enough when the fish are ready to feed...
Many productive coastal areas, such as estuaries, are important fisheries. However, increased respiration associated with the high productivity often occurring in coastal zones may result in low dissolved oxygen conditions (dysoxia). The...
