Seeing red: Coral larvae are attracted to healthy?looking reefs

Settlement cues play an essential role in larval habitat selection and influence post-settlement survival. Recent studies have investigated the impacts of elevated temperature and partial pressure of carbon dioxide ( pCO2) on the ability of marine larvae to locate the reef. In coral larvae, there has been a focus on chemical settlement cues, which are […]

Impact of predicted climate change scenarios on a coral reef meiofauna community

Changes in marine communities in response to elevated CO2 have been reported but information on how representatives of the benthic lower trophic levels will be impacted remains scarce. A laboratory experiment was conducted to evaluate the impact of different climate change scenarios on a coral reef meiofauna community. Samples of the meiofauna community were collected […]

These Itsy-Bitsy Herbivores Could Stage a Huge Coral Reef Rescue

Tiny parrotfish and sea urchins can take over the job of their larger cousins to keep a reef free of algae

Reef fish that conquer fear of sharks may help control excess algae

(University of California - Davis) A UC Davis study found that coral reef fish experience landscapes of fear based on how much shelter from predators is available. But they are willing to move past that fear if the payoff in a delicious meal of algae is high enough.

Environmental constraints on Holocene cold-water coral reef growth off Norway: Insights from a multiproxy approach

High-latitude cold-water coral (CWC) reefs are particularly susceptible due to enhanced CO2 uptake in these regions. Using precisely dated (U/Th) CWCs (Lophelia pertusa) retrieved during research cruise POS 391 (Lopphavet 70.6°N, Oslofjord...Show More Summary

Profitable coral reef fisheries require light fishing

(Wildlife Conservation Society) Fishing is fundamentally altering the food chain in coral reefs and putting dual pressures on the valuable top-level predatory fish, according to new research by the Wildlife Conservation Society, Lancaster University, and other organizations.

Spatial competition dynamics between reef corals under ocean acidification

Climate change, including ocean acidification (OA), represents a major threat to coral-reef ecosystems. Although previous experiments have shown that OA can negatively affect the fitness of reef corals, these have not included the long-term effects of competition for space on coral growth rates.

Fish lightly to keep snapper on the reef

Fishing is fundamentally altering the food chain in coral reefs and putting extra pressure on top-level predator fish, according to new research.

Fish lightly to keep snapper on the reef

(Lancaster University) Scientists have looked at 253 coral reef sites across the Indian Ocean. They found that top-level predator fish -- such as snapper and grouper -- were easily overfished and require a different approach if they are to be conserved.

Software system labels coral reef images in record time

Computer scientists at the University of California San Diego have released a new version of a software system that processes images from the world's coral reefs anywhere between 10 to 100 times faster than processing the data by ha...

Crackdown Could Help End Giant Clam Poaching in Critical Reefs

New regulations in southern China aim to protect coral reefs by putting an end to the thriving trade in giant clam carvings and other handicrafts.

What if the iPhone had never arrived?

Ten years ago the cellphone industry was as teeming with life as a coral reef. Weird, multi-colored Nokias and Samsungs flitted between fronds of seagrass while Sidekicks scuttled in and out of tiny sea caves. Blackberries lumbered through the coral like lions on the hunt, eviscerating all “serious” comers with better software. Show More Summary

noaasanctuaries: It’s Corals Week! Coral reefs are thought to contain the greatest level of biodiversity of any ecosystem in the world – even more than tropical rainforests.  Hundreds of marine organisms rely on coral reefs for food, shelter, mating grounds and more, like this mithrax crab in Gray’s Reef National Marine Sanctuary.

Nearly all coral reefs will be ruined by climate change.

Coral reefs -- and the economies that depend on them -- are in big trouble.

Are tiny grazers the new hope for Caribbean reefs?

Thirty years ago a mysterious disease wiped out long-spined black sea urchins across the Caribbean, leading to massive algal overgrowth that smothered already overfished coral reefs. Now, marine biologists at the Smithsonian Tropical...Show More Summary

New research predicts the future of coral reefs under climate change

New climate model projections of the world's coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth's most important ecosystems.

New research predicts the future of coral reefs under climate change

(University of Miami Rosenstiel School of Marine & Atmospheric Science) New climate model projections of the world's coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth's most important ecosystems.

Ancient city constructed on a coral reef remains the only one of its kind

On the island of Pohnpei, Micronesia rest the remarkable ruins of Nan Madol, the only ancient city ever constructed on top of a coral reef. Referred to as an "engineering marvel" by the Smithsonian and nicknamed the "Venice of the Pacific," this series of over 90 artificial islets could have once housed around 1,000 people.
