1,136 scientists call for protection of deep-sea corals

Public release date: 15-Feb-2004
SEATTLEAt a AAAS press briefing on Sunday at 1:00 PM, marine scientists will release a consensus statement from over a thousand of the world's foremost biologists, calling for governments and the United Nations to protect imperiled deep-sea coral and sponge ecosystems. The statement will be released concurrently at the 7th Conference of the Parties of the UN Convention on Biological Diversity in Kuala Lumpur, Malaysia; in Santiago, Chile; and in Madrid, Spai...

15,589 species threatened

News from The Scientist 2004, 5(1):20041117-03
Published 17 November 2004
More than 15,000 species around the world are at risk of extinction, according to a report released today (November 17) by the International Union for Conservation of Nature and Natural Resources (IUCN). The organization, whose annual list of endangered species is commonly known as the "Red List," found that one in eight birds, almost half of turtles and tortoises, one in four mammals studied, and one i...

A newly discovered species of living baleen whale

Nature 426, 278-281 (20 November 2003)
A new species of Balaenoptera, which is characterized by its unique cranial morphology, its small number of baleen plates, and by its distant molecular relationships with all of its congeners. Our analyses also separated Balaenoptera brydei (Bryde's whale) and Balaenoptera edeni (Eden's whale) into two distinct species, raising the number of known living Balaenoptera species to eight.

Acid oceans spell doom for coral

August, 2004 - The increasing acidity of the world's oceans could banish all coral by 2065, a leading marine expert has warned.

Professor Katherine Richardson said sea organisms that produced calcareous structures would struggle to function in the coming decades as pH levels fell

The expert, based in Denmark, told the EuroScience Open Forum 2004 that human-produced carbon dioxide was radically changing the marine environment.

Arctic warming at twice global rate

November 2004, NewScientist.com - Global warming in the Arctic is happening now, warns the most comprehensive scientific report to date. The reports concludes that the northern ice cap is warming at twice the global rate and that this will lead to serious consequences for the planet.

These include substantial rises in sea level and an intensification of global warming via a positive feedback mechanism, although there may also be benefits. The four-year scientific assessment was conduc... [More]

Australia reef's days 'numbered'

February, 2004 - The Great Barrier Reef off the east coast of Australia will be largely destroyed by 2050 because of rising sea temperatures, according to a new report.

Researchers from Queensland University's Centre for Marine Studies said there was little evidence that corals could adapt quickly enough to cope with even the lowest projected temperature rise of 2C.

Over-fishing and water pollution were also contributing to the destruction of coral on the reef.

Big squid breaks record

July, 2000 - The biggest ever complete specimen of a secretive squid has been found in Antarctica.

The cephalopod stretched 230 centimetres (7.5 feet) from the hooks on its hunting tentacles to its tail, and weighed nearly 30 kilograms (66 lbs).

The squid, Kondakovia longimana, was measured and photographed, and its beak was removed.

This hard mouthpiece, similar to parrot's beak, is usually the only evidence found of the squid.

"They live deep un... [More]

Blue marlin in gulf have high mercury levels

9.2004 - As sport fishes go, the blue marlin is a king of sorts – highly prized for its beautiful shape and its ferocious fighting ability when hooked.

That’s the good news. The bad news is that many blue marlin caught in the Gulf of Mexico contain 20 to 30 times the acceptable levels of mercury.

Texas A&M University at Galveston researchers Jay Rooker and Gary Gill are trying to learn why the mercury levels are so high in blue marlin compared to similar fis... [More]

By 2050 Warming to Doom Million Species, Study Says

National Geographic News
Updated July 12, 2004

By 2050, rising temperatures exacerbated by human-induced belches of carbon dioxide and other greenhouse gases could send more than a million of Earth's land-dwelling plants and animals down the road to extinction, according to a recent study.

"Climate change now represents at least as great a threat to the number of species surviving on Earth as habitat-destruction and modification," said Chris Thomas, a conserv... [More]

Climate warning from the deep

July, 2004 - Strange things are happening in the North Sea. Cod stocks are slumping faster than over-fishing can account for, and Mediterranean species like red mullet are migrating north.

Several sea birds are also in trouble. Kittiwake numbers are falling fast and guillemots are struggling to breed.

And, earlier this summer, hundreds of fulmar (a relative of the albatross) corpses washed up on the Norfolk coast, having apparently starved to death.

Cod Stocks Down More Than 90 Percent Since 1850s

March 2, 2005 - Hundreds of years ago, the oceans off the coast of North America teemed with cod. A new analysis highlights just how few of the big fish remain. The findings indicate that the volume of cod on Nova Scotia's Scotian Shelf has dr0pped more than 90 percent since the 1850s.

Using daily fishing logs from the 1850swhich recorded the number of fish caught, their size and their locationtogether with a population modeling program, Andrew A. Rosenberg of the University of New Ha... [More]

Common household fragrances may be harming aquatic wildlife, study finds

Oct 2004 - Those fragrant soaps and shampoos we casually rinse down the drain may be causing long-term damage to aquatic wildlife downstream by interfering with the animals' natural ability to eliminate toxins from their system, according to a new Stanford University study published by the National Institutes of Health (NIH).

Writing in the NIH journal Environmental Health Perspectives, Stanford scientists described the biological damage that occurred when they exposed California muss... [More]

Complete collapse of North Atlantic fishing predicted

February 2002, From New Scientist - The entire North Atlantic is being so severely overfished that it may completely collapse by 2010, reveals the first comprehensive survey of the entire ocean's fishery.

"We'll all be eating jellyfish sandwiches," says Reg Watson, a fisheries scientist at the University of British Columbia. Putting new ocean-wide management plans into place is the only way to reverse the trend, Watson and his colleagues say.

Deep fish 'trawled to oblivion'

February, 2002 - Deep-sea trawlers are destroying populations of fish and other creatures in the ocean at an alarming rate, according to research presented at the American Association for the Advancement of Science annual meeting in Boston.

Fishermen are now using military sonar to hunt in the deep ocean, but the slow life cycles of the species that live hundreds of metres below the surface mean their populations will collapse if they are exposed to industrial-scale exploitation.

Dolphin 'bycatch' death evidence

February 2004 - Plymouth, United Kingdom — Our ship Esperanza has been monitoring UK fisheries for evidence of dolphin deaths in trawler nets. Yesterday we found what we had hoped not to: five dead dolphins, floating in the vicinity of two sets of pair trawlers.

The five adult dolphins had obviously been trapped in the net and drowned in the struggle to escape. All of the animals had cuts to their beaks, fins and flippers. A piece of net was also discovered near the carcasses.<... [More]
