Light Shed on Hawaiian Reef Fish Food Sources and Trophic Positions

NOAA-funded scientists studying the diets of 22 species of Hawaiian coral reef fish living at both shallow (0-30 meters) and mesophotic (30-150 meters) depths found that the food source differed for invertebrate-feeding and omnivorous fishes and remained the same for plankton-feeding fishes. Although the sources of food were different between shallow and mesophotic depths, the […]

Research Links Land Use, Shoreline Hardening, and Species Abundance

Recent NCCOS research provides solid evidence that reduced aquatic species abundance in the Northeast is linked with increased agricultural land use and hardened shorelines. Results from the study are published in the September issue of Estuaries and Coasts and highlighted in Coastal & Estuarine Science News (CESN). The overall research project evaluated 587 sites, 39 sub-estuaries, and 15 […]

Hypoxia Leads to Atlantic Croaker Decline in Gulf of Mexico, Models Show

A team of scientists led by Louisiana State University (LSU) developed a model to understand the impacts of hypoxia (low oxygen) on Atlantic croaker in the northern Gulf of Mexico. Results indicate that chronic large hypoxic zones could result in model estimates of a 25 percent reduction in the long-term population abundance of Atlantic croaker over a […]

Study of Freshwater Turtles to Improve Treatment of Toxins in Sea Turtles

New research is paying off long-term for endangered sea turtles facing illness and even death during Florida red tides. From 2011-2014, the NCCOS sponsored project “Brevetoxin Metabolism and Physiology – A Freshwater Model of Morbidity in Endangered Sea Turtles” used non-endangered freshwater turtles as models to determine the effects of Florida red tide on endangered sea […]

Why the Exceptional Toxicity during the 2015 West Coast Harmful Algal Bloom?

New research sponsored by NCCOS explains what might have caused the high toxicity in Monterey Bay, CA during the massive 2015 toxic bloom of the marine diatom Pseudo-nitzschia along the West Coast of the United States. Based on NCCOS research, warm water, nutrients, or a combination of factors may have caused the bloom and to some extent […]

Second ‘Cytobot’ Deployed in Texas Harmful Algae Early Warning Sensor Network

NCCOS-funded investigators from Texas A&M University (TAMU) successfully deployed an Imaging Flow Cytobot (IFCB) on a pier near Freeport, Texas. This is the second cytobot deployed in the Gulf of Mexico as part of an expanding cytobot network to provide early warning of harmful algal blooms (HABs) that impact coastal resources. Blooms of Karenia brevis, […]

Beating the Spread: NCCOS Science Helps Managers NOT Gamble with Invasive Species

A recent publication by NCCOS-funded scientists shows how new invasive species in the Great Lakes are easily dispersed by Lake Michigan and Lake Erie currents. The team, led by Dr. Dima Beletsky of the NOAA Cooperative Institute for Great Lakes Research at the University of Michigan, modeled dispersal throughout the lakes from nearshore locations, such as […]

Great Lakes Conference Highlights NCCOS Research

The International Association for Great Lakes Research’s (IAGLR) annual Conference on Great Lakes Research showcases the latest findings on the Great Lakes and other large lakes around the world. This year’s conference, held last month in Detriot, Michigan, highlighted a range of NCCOS research, including: ecological forecasting, remote sensing, habitat mapping, modeling, harmful algal blooms, chemical […]
