In order to develop better methods of treatment, a researcher from the Mote Marine Lab received harmful algal bloom Event Response Program funds to investigate the physiological effects of brevetoxin exposure on manatees. A persistent red tide bloom of algae that produces this substance is responsible for a record number of manatee deaths this spring. Mote is working with [...]
From the moment they are born, sea turtles fight to survive. Buried alive, they dig themselves out and evade hungry crabs and birds as they crawl to the ocean, where they begin a long and treacherous migration. One out of 1,000 will survive into adulthood. And those that do will bear a toxic burden. Scientists [...]
A single-celled plant known as Gambierdiscus is responsible for the most common cause of harmful algae poisoning worldwide: ciguatera. The algae’s potent neurotoxin–called ciguatoxin–is found in over 400 species of fish and is conservatively estimated to sicken more than 50,000 people every year. Two years ago, researchers from NOAA’s National Centers for Coastal Ocean Science [...]
Scientists at the Caribbean Coral Reef Institute at the University of Puerto Rico identified locations and size of reef fish spawning aggregations by the sounds they make. The success of many commercially valuable species in the Caribbean requires annual spawning aggregations of reef fishes; aggregation behavior creates extreme vulnerability to overfishing. The scientists developed a [...]
NOAA investigators and their partners embarked on a year-long study to determine the origins of coral polyps and fish species seeding the reefs of the Commonwealth of the Northern Mariana Islands and Guam so that the islands’ officials can take customized measures to protect them from overharvesting or other damage. Using drifting sensors coupled with a computer [...]
To solidify the courtroom validity of wildlife forensic techniques, a scientific working group formed two years ago to standardize methodologies and establish best practices for handling many species and evidence types the discipline encounters. Last week the group convened to put final touches on the documents, which should address criticisms in a 2009 report by the National [...]
NOAA researchers recently published An Integrated Biogeographic Assessment of Reef Fish Populations and Fisheries in Dry Tortugas: Effects of No-take Reserves, an analysis of both biological and socioeconomic changes resulting from the remote Florida marine reserve during its first five years. The report indicates that there seemed to be an early increase in certain fish species within [...]
In October, NOAA scientists and partners collected seafloor photos and videos from over 355 locations around the St. Thomas East End Reserve, and in the Virgin Islands National Park and Virgin Islands Coral Reef National Monument. These new data will support management practices such as permitting, restoration, fisheries, climate change and scientific research; the depth [...]
