Depth affects Algal Symbiont composition in Caribbean Coral

First of Four Articles on Research Findings Comparing Shallow and Mesophotic Coral Reefs NCCOS-funded researchers investigating the diversity of symbiotic algae (Symbiodinium spp.) associated with the coral Agaricia lamarcki in Puerto Rico and the U.S. Virgin Islands found the coral’s algal associations change with depth. Light-dependent corals form a mutually beneficial relationship (symbiosis) with the […]

Experts Shape the Future of Caribbean Coral Restoration Science and Practice

Adapted text from Tali Vardi Coral restoration scientists, practitioners, and resource managers gathered at the Workshop to Advance the Science and Practice of Caribbean Coral Restoration in Fort Lauderdale, FL last month to address the rapidly expanding and evolving role of active coral restoration in the management of coral reef ecosystems. The three-day meeting facilitated […]

First Compendium on Deep-water Algae of Puerto Rico Published

A new taxonomic publication describes the relatively unknown algal flora of mesophotic coral ecosystems in Puerto Rico. These ecosystems are characterized by the presence of light-dependent corals and associated communities found at depths ranging from 100 to 500 feet deep. The work, published in a recent issue of Smithsonian Contributions to Botany, was supported partly by the […]

Data Collected for Map of Deep Coral Reefs off St. John, USVI

This past summer NCCOS scientists collected underwater photos and videos from mesophotic ocean depths (30–100 meters) between Vieques Island and St. John in the U.S. Caribbean. The data will support the development of a new benthic habitat map that will depict the distribution of mesophotic coral reef ecosystems on the insular shelf. The new habitat […]

NCCOS in the Caribbean: Arliss Winship Field Blog

How the travelling salesman saved a day of Caribbean field work | by Arliss Winship It’s not every day that an ecological modeler gets out in the field. I spend most of my time behind a computer synthesizing ecological data sets and conducting statistical analyses. Not the most fun activities one associates with marine science. […]

NCCOS Leads Key Topics at International Coral Reef Symposium

This week, staff from the National Centers for Coastal Ocean Science (NCCOS) led special sessions and gave individual presentations at the 13th International Coral Reef Symposium in Honolulu, Hawaii. The symposium is one of the largest international gatherings that bring together researchers, managers, policy makers, non-governmental organizations, and the general public to share and discuss recent […]

Environmental Variables Influence Toxic Ciguatera Algae Growth and Distribution

A new study describes optimal growth conditions for several species and strains of the benthic marine dinoflagellate Gambierdiscus and highlights how these species and strains respond differently to varying levels of salinity, light, and temperature. These environmental factors, along with suitable seafloor habitat, predict the geographic distribution of Gambierdiscus. Gambierdiscus is a genus of tropical and subtropical […]
