NCCOS Study Finds Sharks and Top Predators Depend on Benthic Algae in Healthy Coral Reefs

In a newly published study, NCCOS researcher link sharks and other top predators with primary producers (benthic algae) in pristine, healthy coral reef ecosystems.  “We used chemical signatures of carbon and nitrogen found in the tissues of the algae, invertebrates, fish, and sharks from the Papahānaumokuākea Marine National Monument (PMNM) to trace the extent benthic algae influences […]

Algae’s hunger ramps up red tide toxins | HeraldTribune.com

The mysterious red tide toxin that has killed a record number of manatees and brought countless dead fish to Southwest Florida beaches over the past few months could finally have an explanation: The algae that produce the toxin are hungry. A significant new study of the algae, Karenia Brevis (sic), suggests that the organisms release […]

Recreational Water Pathogen Detection Workshops Build Skills for State Labs

The North Carolina Biotechnology Center funded NOAA and academic researchers to develop a training facility for public health officials and resource managers in advanced molecular methods to detect pathogens and harmful algae species more quickly and effectively. The first workshop, held March 11 – 15, 2013,  covered quantitative polymerase chain reaction techniques to detect Enterococcus, the […]

Gulf of Mexico Algae Shield Themselves with Toxins When Hungry

A species of algae responsible for red tides plaguing Gulf coast communities protects itself by becoming highly toxic when it’s hungry and vulnerable to being eaten by predators, say scientists from NOAA’s National Centers for Coastal Ocean Science and North Carolina State University. The red tide organism, called Karenia brevis, reacts to low levels of nutrients–particularly phosphorus–by […]

All You Can Eat: usoceangov NOAA Ocean Today kiosk video

Watch as hunters become the hunted in this story of a delicious but damaging invasive predator and efforts to remove them from our fragile reefs.  Lionfish released in U.S. waters are ruining these critical resources by eating fish and shellfish that are valuable to you and me, as well as the reefs they live on. […]

Locavores, Meet Invasivores: Cooking and Eating Invasive Lionfish at Haven – Houston – Restaurants and Dining – Eating Our Words

Invasive species are nothing new. Neither is eating them, as anyone who’s eaten Cambodian water spinach — much of it grown here in Houston — will tell you. But bringing in water spinach from Cambodia and growing it for profit (despite its status over here as a noxious weed) is entirely different from eating species […]

Cheaper Ciguatoxin Assay May Rely on Proxy Molecule

A recently published finding may contribute to the development of a long-elusive affordable ciguatoxin detector, crucial for equatorial peoples worldwide at risk of contracting a severe type of seafood poisoning. While researching toxicity differences in the several species of tropical algae that cause ciguatera, researchers from the National Centers for Coastal Ocean Science and partners […]
