Sulfur stable isotope indicators of residency in estuarine fish
Sulfur stable isotope indicators of residency estuarine fish
2014/4/4
Estuarine fish may remain as residents in areas with favorable conditions for feeding and refuge, but become mobile and transient where conditions are less favorable. We developed a new approach invol...
Severe droughts reduce estuarine primary productivity with cascading effects on higher trophic levels
higher trophic levels Severe droughts reduce estuarine
2014/4/4
Using a 10-yr time-series data set, we analyzed the effects of two severe droughts on water-quality and
ecosystem processes in a temperate, eutrophic estuary (Neuse River Estuary, North Carolina). Du...
Estuarine oxygen dynamics: What can we learn about hypoxia from long-time records in the Delaware Estuary?
Estuarine oxygen dynamics Delaware Estuary
2014/4/16
Hypoxia and anoxia occurred in the upper Delaware Estuary throughout much of the 20th century and
diminished over the past several decades. I reviewed 30 yr of data from my laboratory’s research effo...
Understanding How Disease and Environment Combine to Structure Resistance in Estuarine Bivalve Populations
Delaware bay oyster parasites ecology of infectious diseases oyster population genetics parasite hosts
2015/7/6
Delaware Bay oyster (Crassostrea virginica) populations are influenced by two lethal parasites that cause Dermo and MSX diseases. As part of the US National Science Foundation Ecology of Infectious Di...
Hydrodynamic control of phytoplankton loss to the benthos in an estuarine environment
Hydrodynamic control phytoplankton loss to the benthos estuarine environment
2014/4/18
Field experiments were undertaken to measure the influence of hydrodynamics on the removal of phytoplankton by benthic grazers in Suisun Slough, North San Francisco Bay. Chlorophyll a concentration bo...
Coastal oceanographic processes influence the growth and size of a key estuarine species, the Olympia oyster
Coastal oceanographic processes influence the Olympia oyster
2014/4/17
Here we empirically demonstrate that a tidal exchange gradient in a central California estuary leads to
inversely related spatial gradients in upwelled nutrients and water residence times. As a resul...
Enhanced methane oxidation in an estuarine turbidity maximum
Enhanced methane oxidation estuarine turbidity maximum
2014/4/22
Methane and suspended particulate matter (SPM) concentrations, monitored bimonthly during one hydrological year (2003-2004) along 70 km transects in the tidal regions of the Garonne and Dordogne river...
Uptake of Spartina-derived humic nitrogen by estuarine phytoplankton in nonaxenic and axenic culture
Spartina-derived humic nitrogen estuarine phytoplankton nonaxenic and axenic culture
2014/5/5
Humic substances are a collection of colored organic acids characterized by high molecular weight and low nitrogen (N) content that are thought to be biologically recalcitrant. We examined a suite of ...
Long-term temporal and spatial trends in phytoplankton biomass and class-level taxonomic composition in the hydrologically variable Neuse-Pamlico estuarine continuum, North Carolina, U.S.A.
Long-term temporal spatial trends phytoplankton biomass class-level taxonomic composition hydrologically variable Neuse-Pamlico estuarine continuum North Carolina U.S.A.
2014/5/4
Phytoplankton diagnostic photopigments in near-surface waters (~0.5 m) were identified and quantified by high-performance liquid chromatography beginning in April 1994 in the Neuse River Estuary and i...
Interactive regulation of dissolved copper toxicity by an estuarine microbial community
Interactive regulation copper toxicity estuarine microbial community
2014/5/19
Cultured marine microorganisms under copper stress produce extracellular compounds having a high affinity for copper (copper-complexing ligands). These ligands are similar in binding strength to those...
Black carbon in estuarine and coastal ocean dissolved organic matter
Black carbon in estuarine coastal ocean dissolved organic matter
2014/5/14
We measured black carbon (BC) in ultrafiltered, high-molecular weight dissolved organic matter (UDOM) in surface waters of Delaware Bay, Chesapeake Bay, and the adjacent Atlantic Ocean (U.S.A.) to inv...
Cycling of colloidal organic carbon and nitrogen during an estuarine phytoplankton bloom
colloidal organic carbon and nitrogen estuarine phytoplankton bloom
2014/5/22
To establish the influence of phytoplankton blooms on the cycling of dissolved and particulate species of organic carbon and nitrogen, we conducted a field study during a series of blooms in a coastal...
Stable carbon and nitrogen isotope composition of aquatic and terrestrial plants of the San Francisco Bay estuarine system
Stable carbon nitrogen isotope composition aquatic and terrestrial plants San Francisco Bay estuarine system
2014/5/27
We report measurements of seasonal variability in the C-N stable isotope ratios of plants collected across the habitat mosaic of San Francisco Bay, its marshes, and its tributary river system. Analyse...
Plasticity in vertical migration by native and exotic estuarine fishes in a dynamic low-salinity zone
vertical migration native and exotic estuarine fishes a dynamic low-salinity zone
2014/5/26
We investigated the degree of flexibility in retention strategies of young fishes in the low-salinity zone (LSZ) of the San Francisco Estuary during years of highly variable river flow. We conducted d...

2014/5/26
In this paper we assess whether the bacterial compositional succession that occurs along an estuarine salinity gradient is accompanied by changes in both community and single-cell metabolic activity i...
