Molecular Characterization and Hypoxia-Induced Upregulation of Neuronal Nitric Oxide Synthase in Atlantic Croaker: Reversal by Antioxidant and Estrogen Treatments
Neuronal nitric oxide synthase (nNOS) catalyzes production of nitric oxide in vertebrate brains. Recent findings indicate that endothelial NOS and reactive oxygen species (ROS) are significantly increased during hypoxic stress and are modulated by antioxidants. However, the influence of antioxidants and steroids on nNOS upregulation by hypoxia is largely unknown ...
Molecular Response of the Bloom-Forming Cyanobacterium, Microcystis aeruginosa, to Phosphorus Limitation
Cyanobacteria blooms caused by species such as Microcystis have become commonplace in many freshwater ecosystems. Although phosphorus (P) typically limits the growth of freshwater phytoplankton populations, little is known regarding the molecular response of Microcystis to variation in P concentrations and sources. For this study, we examined genes involved in ...
Molecular structure characterization of riverine and coastal dissolved organic matter with ion mobility quadrupole time-of-flight LCMS (IM Q-TOF LCMS)
Deciphering molecular structures of dissolved organic matter (DOM) components is key to understanding the formation and transformation of this globally important carbon pool in aquatic environments. Such a task depends on the integrated use of complementary analytical techniques. We characterize the molecular structure of natural DOM using an ion mobility ...
Mollusks taken by Beam Trawl in the vicinity of Grays Reef National Marine Sanctuary on the Continental Shelf off Georgia, Southeastern U.S.
Mollusks were sorted from samples of shell hash (obtained as bycatch during NOAA-sponsored studies of larval and juvenile fish distribution), and analyzed to gain qualitative insights on species composition, distribution and habitat affinities of the molluscan fauna on the continental shelf off Georgia. Samples came from beam trawls at 37 ...
Monitoring abnormal bio-optical and physical properties in the Gulf of Mexico
The dynamic bio-optical and physical ocean properties within the Gulf of Mexico (GoM) have been identified by the Ocean Weather Laboratory. Ocean properties from VIIRS satellite (Chlorophyll and Bio-Optics and SST) and ocean-circulation models (currents, SST and salinity) were used to identify regions of dynamic changing properties. The degree of ...
Monitoring Approaches for Early Warning of Domoic Acid Events in Washington State
On the U.S. west coast, blooms of the potentially toxic diatom Pseudo-nitzschia can cause amnesic shellfish poisoning (ASP), resulting in economic impacts to coastal economies and public health concerns. The transfer of toxin, via filter feeding of Pseudo-nitzschia or ingestion of filter feeding organisms, to shellfish, crustaceans, seabirds, finfish, and ...
Monitoring Hawaii’s Marine Protected Areas: Examining Spatial and Temporal Trends Using a Seascape Approach
Hawaii's coastal marine resources have declined dramatically over the past 100 years due to multiple anthropogenic stressors including overfishing, coastal development, pollution, overuse, invasive species and climate change. It is now becoming evident that ecosystem-based management, in the form of marine protected areas (MPAs), is necessary to conserve biodiversity, maintain ...
Monitoring Oregon Coastal Harmful Algae: Observations and Implications of a Harmful Algal Bloom-Monitoring Project
The accumulation of domoic acid (DA) and saxitoxins (STX), phycotoxins produced by some species of Pseudo-nitzschia and Alexandrium, respectively, in coastal food webs are a focus of research on the West Coast of the United States due to the deleterious effects they have on coastal ecosystems and economies. Results are ...
Montastraea cavernosa corallite structure demonstrates distinct morphotypes across shallow and mesophotic depth zones in the Gulf of Mexico
This study assessed morphological variation of the depth-generalist coral Montastraea cavernosa across shallow and mesophotic coral ecosystems in the Gulf of Mexico (GOM) using thirteen corallite metrics. While corallite structure differed significantly across sites, we observed that mean corallite diameters were smaller and spacing was greater in mesophotic corals as ...
Movement of Juvenile Weakfish (Cynoscion regalis) and Spot (Leistomus xanthurus) in Relation to Diel-cycling Hypoxia in an Estuarine Tributary: Assessment Using Acoustic Telemetry
Fish movement and the spatial and temporal dynamics of hypoxia determine hypoxia exposure and the effect of poor water quality on nursery habitat function. Although water quality criteria for dissolved oxygen (DO) are well defined, hypoxia exposure of juvenile estuary-dependent fishes in situ is largely unknown. Thirty-one juvenile weakfish Cynoscion ...
Movements of reef fish across the boundary of the Virgin Islands Coral Reef National Monument in Coral Bay, St. John, USVI
The Virgin Islands Coral Reef National Monument (VICRNM) was created to expand the protection of the marine ecosystems around St. John. Monument boundaries were not designed using ecological criteria, but were instead the result of historical land ownership and the Territorial Submerged Lands Act of 1974. This study used acoustic ...
Moving from a regional to a continental perspective of Phragmites australis invasion in North America
We use a regional comparison of Phragmites australis (common reed) subsp. americanus, P. australis subsp. berlandieri and introduced P. australis (possibly five sublineages) in the Chesapeake Bay, the St Lawrence River, Utah and the Gulf Coast to inform a North American perspective on P. australis invasion patterns, drivers, impacts and ...
