Coral reefs are tremendously important for ocean biodiversity. Unfortunately they have been in great decline in recent years, much of it due to the effects of global climate change. One such effect, called bleaching, occurs when the symbiotic algae that are essential for providing nutrients to the coral either lose their identifying photosynthetic pigmentation and their ability to perform photosynthesis or disappear entirely from the coral's tissue. Without a healthy population of these algae, the coral cannot survive.

Shocks caused by climate and seasonal change could be used to aid recovery of some of the world's badly-degraded coral reefs, scientists have proposed. Marine scientists suggest that it may be possible to restore living coral cover to a badly-degraded reef system -- though not easy.

The best real estate for coral reefs over the coming decades will no longer be around the equator but in the sub-tropics, new research suggests.

A new study conducted at One Tree Island in the Great Barrier Reef has established that reef fish larvae can smell the presence of coral reefs from as far as several kilometers offshore, and use this odor to find home.

How do you track a fish underwater? Rethinking the traditional, ad hoc approach to acoustic telemetry, scientists have proposed a new state-space model for analyzing fish movement data collected by marine observation networks. Its goal is to quantify the uncertainty associated with this imperfect locating system, and to improve its accuracy.

A computer simulation has revealed the epic, ocean-spanning journeys traveled by millimeter-sized coral larvae through the world's seas. The model is the first to recreate the oceanic paths along which corals disperse globally, and will eventually aid predictions of how coral reef distributions may shift with climate change.

Scientists are taking the public with them to study the world’s coral reefs, thanks to 360 degree panoramas from Google's underwater street-view format. Results from this pioneering project will allow ecologists to harness people power to discover how coral reefs are responding to climate change.

Small prey fish can grow a bigger 'eye' on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new research has found. Researchers have made a world-first discovery that, when constantly threatened with being eaten, small damsel fish not only grow a larger false 'eye spot' near their tail -- but also reduce the size of their real eyes.
