The Role of Nitric Oxide in Promoting Heterosigma ...

Heterosigma akashiwo has emerged as a threat to finfish and shellfish stocks resulting in significant impacts to the coastal economy. We are working to identify the mechanisms and nitrogen sources ...

Toward a Predictive Understanding of Cochlodinium ...

Large blooms of Cochlodinium polykrikoides have occurred throughout the lower Chesapeake Bay and its tributaries in recent decades and appear to be followed by increasingly intense blooms of the ichthyotoxic ...

Towards a Predictive Understanding of Our Ecosyste...

Cyanobacteria blooms and toxin production are an urgent contemporary problem in the US and worldwide. Water quality models are important tools for managing these problems, but currently the utility of ...

Toxicity and Potential Food-Web Impacts of Alexand...

Once limited to the U.S. south Atlantic and the Gulf of Mexico, Alexandrium monilatum has extended its range to the lower Chesapeake Bay, where it affects commercial fisheries and shellfisheries ...

Trophic Transfer and Effects of HAB Toxins in Alas...

This project aims to determine harmful algal bloom species composition and cell densities in Alaskan waters, and to model toxin transfer pathways to zooplankton, shellfish, finfish, and marine mammals, and ...

Uncovering the Mechanisms behind Wintertime Occurr...

Paralytic shellfish toxins (PSTs) from the alga Alexandrium hinder the wintertime geoduck clam fishery in Southeast Alaska. With no winter blooms of Alexandrium on record, scientists hypothesize that the toxins ...

A new study supported by NCCOS shows that the presence of zooplankton grazers dramatically increases toxin production in the marine dinoflagellate Alexandrium catenella, a species notorious for its paralytic shellfish ...

Algae with Mixed Feeding Capabilities May have Adv...

New NCCOS-sponsored research shows the importance of “mixotrophy”—the ability to photosynthesize like a plant and consume like an animal—to the growth of some single-celled organisms, such as the toxic dinoflagellate ...

Study Evaluates Technologies for Early Warning of ...

Passive solid-phase adsorption toxin tracking, or SPATT, employs a synthetic resin contained in a mesh bag that adsorbs dissolved biotoxins from the water. The SPATT resin bags can be suspended ...

New Research from NCCOS Could Improve Survival of ...

The threatened Florida manatee, Trichechus manatus latirostris, inhabits coastal environments where blooms of the toxic red tide dinoflagellate, Karenia brevis, frequently occur. K. brevis produces a suite of neurotoxins, called ...
