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...

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...

  Vital clues to coral reef recovery have been identified in a remarkable research project in which three scientists labored to hand-build 30 coral reefs from hundreds of tons of rock and gravel. Working in a shallow, sandy area of Kimbe Bay, Papua New Guinea, the team constructed their artificial reefs over several weeks, with just a boat and their bare hands, to find out whether it is possible to rescue a damaged coral reef from obliteration and restore its richness....

Coral Algae Could One Day Be Used In Sunscreen Pill
2011-08-31 07:00:52

  British researchers studying coral in Australia´s Great Barrier Reef could create a pill that would prevent sunburn in people, The Telegraph is reporting. Despite living in shallow water, coral does not suffer from the harmful effects of UV rays as it is able to produce a "natural sunscreen." Coral converts compounds produced by algae living inside it to make a sunscreen which protects both the coral and the algae from sunburn, the researchers discovered. Lead researcher...

Wildlife Conservation Society leads global assessment showing where climate stresses on reef systems will be and places to focus management Marine researchers from the Wildlife Conservation Society and other groups have created a map of the world's corals and their exposure to stress factors, including high temperatures, ultra-violet radiation, weather systems, sedimentation, as well as stress-reducing factors such as temperature variability and tidal dynamics. The study, say the authors,...

The Great Barrier Reef is being damaged by the use of agricultural pesticides, claims a new Australian government report on water quality at the World Heritage site. According to the Australian Associated Press (AAP), the report shows that more than 60,000 pounds of pesticides leak into the Great Barrier Reef each year, while the government has deemed that the water in the reef is "moderate" in quality. The report card, which was released on Friday, was based on data collected from 2008 and...

Australian scientists today announced they have sequenced the genome of the staghorn coral Acropora millepora, a major component of the Great Barrier Reef and coral reefs worldwide. This is the first animal genome project to be carried out entirely in Australia, and is an important milestone in Australian biotechnology and in the study of coral reefs, said the researchers from the ARC Centre of Excellence for Coral Reef Studies and the Australian Genome Research Facility (AGRF). "This is a...

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...

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...

  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
