Indo-Pacific coral reefs disappearing more rapidly than expected
08-07-2007 · EurekAlert!Corals in the central and western Pacific ocean are dying faster than previously thought, University of North Carolina at Chapel Hill researchers have found. Nearly 600 square miles of reef have disappeared per year since the late 1960s, twice the rate of rainforest loss.

- Tiny 'housekeeper' crabs help prevent coral death in South Pacific
10-23-2006 · EurekAlert!
Tiny crabs that live in South Pacific coral help to prevent the coral from dying by providing regular cleaning "services" that may be critical to the life of coral reefs around the world, according to scientists from the University of California, Santa Barbara.

- Palau's coral reefs show differential habitat recovery following the 1998 bleaching event
05-15-2007 · EurekAlert!
Coral reef bleaching, believed to be one of the detrimental effects of climate change, may receive a welcomed "buffer" through effective local management, according to new research by a team of scientists recording the long-term recovery of coral reefs in Palau and elsewhere.

- Stormy days ahead for coral reefs
11-28-2006 · EurekAlert!
Scientists from the ARC Center of Excellence for Coral Reef Studies have produced the world's first engineering model to predict how much damage a reef is likely to suffer when confronted with an angry sea. In a paper in Nature, Dr. Joshua Madin and Dr. Sean Connolly use mathematical models to calculate the forces that coral is subjected to by waves or storm surge and the probability of the colonies being ripped from the seabed.

- Coral reefs unlikely to survive in acid oceans
12-14-2007 · EurekAlert!
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean's chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution's Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98 percent of present-day reef habitats will be bathed in water too acidic for reef growth.

- Ancient coral reef tells the history of Kenya's soil erosion
04-10-2007 · EurekAlert!
Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

- Ongoing collapse of coral reef shark populations
12-04-2006 · EurekAlert!
Investigators have revealed that coral reef shark populations are in the midst of rapid decline, and that "no-take zones" -- reefs where fishing is prohibited -- do protect sharks, but only when compliance with no-take regulations is high. The findings, reported by William Robbins and colleagues at James Cook University and its ARC Centre of Excellence for Coral Reef Studies, appear in the December 5th issue of Current Biology.

- Innovative Tagging Technique May Help Researchers Better Protect Fish Stocks
08-07-2007 · Woods Hole Oceanographic Institution (WHOI)
WHOI fish ecologist Simon Thorrold has received a research
grant from the David and Lucile Packard Foundation to use harmless
chemical tags to track the dispersal of the larvae
of coral reef fishes in the western Pacific Ocean. The unique tagging
experiment will help determine if Marine Protected Areas aid in
the recovery of fish stocks.

12-12-2006 · EurekAlert!
Large scale coral die-offs are now occurring more frequently than at any time in the last 11 000 years, according to a new study by Australian-based scientists.Investigations by Associate Professor John Pandolfi, of the ARC Centre of Excellence in Coral Reef Studies and the University of Queensland, of fossilized reefs in Papua New Guinea show how often the reefs were "wiped out" by disastrous events in past times.

- Weird 'Engine of The Reef' Revealed
08-30-2007 · EurekAlert!
A team of coral researchers has taken a major stride towards revealing the workings of the mysterious ‘engine’ that drives Australia’s Great Barrier Reef, and corals the world over. The science has critical importance in understanding why coral reefs bleach and die, how they respond to climate change - and how that might affect humanity, they say.
