Big Fish Reveal Shelter Secrets On Reefcam
2012-02-14 04:07:45

When it comes to choosing a place to hang out, big reef fish like coral trout, snappers and sweetlips have strong architectural preferences. The choices big fish make on where to shelter could have a major influence on their ability to cope with climate change, say scientists from the ARC Centre of Excellence for Coral Reef Studies at James Cook University. In research aimed at understanding the process of fish population decline when coral reefs sustain major damage, PhD student James...

Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of “zooxanthellae” can have different levels of thermal tolerance — a feature that was only known previously for corals with a mix of zooxanthellae. Zooxanthellae are algal cells that live within the tissue of living coral and provide the coral host with energy; the relationship is crucial for the...

Two eminent tropical marine scientists today urged Australians to get behind a plan by the Federal Government to transform nearly a million square kilometers of the Coral Sea into the world´s largest marine park. “The Coral Sea is one of a handful of places in the world where a very large oceanic no-take park can be created and monitored in a single national jurisdiction,” say Professors Terry Hughes and Bob Pressey of the ARC Centre of Excellence for Coral Reef Studies...

Parrot Fish Are The Constant Gardeners Of The World's Reefs
2011-12-09 03:38:26

Australian scientists have urged greater consideration for the brilliantly-hued parrot fishes that tend and renew the world´s imperiled coral reefs. “Parrotfishes are the constant gardeners of the reef. They play a crucial role in keeping it healthy, suppressing weed, removing sediment and helping the corals to regrow after a setback,” explains Professor David Bellwood of the ARC Centre of Excellence for Coral Reef Studies and James Cook University. In a major new study...

Corals Can Sense What's Coming
2011-11-19 04:42:31

Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as the Earth´s climate warms. Coral bleaching, one of the most devastating events affecting coral reefs around the planet, is triggered by rising water temperatures. It occurs when the corals and their symbiotic algae become heat-stressed, and the algae which feed the corals either die or are expelled by the coral. There have been seven major bleaching events globally in the past...

Australia should show a strong international lead in protecting the oceans and sea-life against overexploitation and other human impacts, a leading marine scientist says. In the lead up to the ℠Coral Reefs: Coast to Coast Symposium´ to be held in Fremantle, WA, on October 20-21, convener Professor Terry Hughes, the director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, is urging governments State and Federal to up Australia´s commitment to...

New Study Uncovers Predictable Sequence Toward Coral Reef Collapse
2011-09-29 04:06:48

Research identifies 8 factors that can alert managers to the threat of overfishing in otherwise healthy-looking reefs Coral reefs that have lots of corals and appear healthy may, in fact, be heading toward collapse, according to a study published by the Wildlife Conservation Society and other groups. Using data from coral reef systems across the western Indian Ocean, an international team of researchers identified how overfishing creates a series of at least eight big changes on reefs...

Image 1 - Analysis Confirms Sharks Are In Trouble

Sharks are in big trouble on the Great Barrier Reef and worldwide, according to an Australian-based team who have developed a world-first way to measure rates of decline in shark populations. “There is mounting evidence of widespread, substantial, and ongoing declines in the abundance of shark populations worldwide, coincident with marked rises in global shark catches in the last half-century,” say Mizue Hisano, Professor Sean Connolly and Dr William Robbins from the ARC Centre...

An international team of scientists has achieved a major breakthrough in fishing sustainability on coral reefs which could play a vital role in preventing their collapse. “Fishermen and scientists have long wondered how many fish can be taken off a reef before it collapses, says Dr Nick Graham of the ARC Centre of Excellence (ARC CoE) for Coral Reef Studies and James Cook University. “The consequences of overfishing can be severe to the ecosystem and may take decades to...

Counting Fish From Space

Short-spined Crown-of-thorns Starfish, Acanthaster brevispinus
2013-08-12 14:37:20

The short-spined crown-of-thorns starfish (Acanthaster brevispinus) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that includes the Great Barrier Reef, the Philippines, and the Seychelles in the Indian Ocean. Because these areas are so far away from one another, the full range of this starfish cannot be known, but it can be said that it resides in a tropical or subtropical environment. It was first discovered by W.K. Fisher, who...

Barrier Reef Anemonefish, Amphiprion akindynos
2012-05-11 12:04:43

The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean.  It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...

Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...

Elongate Surgeonfish, Acanthurus mata

The Elongate Surgeonfish, (Acanthurus mata), is a species of tropical fish found in the Indo-Pacific, and can be found as far north as Southern Japan and south to the Great Barrier Reef. Some also live as far west as South Africa and as far east as the Tuamotu Islands. Its main habitat is steep slopes around coral reefs. This is a light blue fish with numerous brown stripes running down the length of the body, although over time it is able to change color to become blue overall. It has a...
