Florida: Mysterious algae blooms worry biologists

Peter Frezza, a biologist with Audubon of Florida's Keys office, measures water clarity on the Twin Key banks. The photo was taken from just below the surface and reveals the water's green tinge as a result of the algae bloom in parts of Florida Bay.

Algae has turned Florida Bay's waters a murky green, threatening the ecosystem below. What's causing the sudden blooms isn't clear.

Only a day earlier, the heart of Florida Bay's world-renowned fishing ground was clear enough to count turtle grass blades six feet down. Now, Pete Frezza stared into water so thick with algae it looked an awful lot like pea soup.

Colossal squid goes under the knife in New Zealand

The colossal squid, which weighs half a tonne, is thought to be the largest ever recovered intact

The sight of an enormous, tentacled creature splayed out on an operating table may seem like the stuff of science fiction, but for scientists in New Zealand tomorrow it will just be another day at the office.

The Museum of New Zealand Te Papa is about to begin experiments on one of the ocean's most enigmatic creatures: the colossal squid. Only dismembered or digested parts of the squid are ordinarily found, but this rare intact specimen was caught in Antarctic waters in February 2007.

17 Elephants Butchered for Ivory in African Park

Poachers from an array of factions have killed 17 elephants in eastern Democratic Republic of the Congo since mid-April, conservationists announced.

The killings of the first 14 animals were announced early last week, and an additional 3 were found Friday.

The rare animals were slaughtered in Virunga National Park, most likely to feed Asia's demand for ivory.

Virunga's ecosystem has come under increasing pressure from a bevy of military groups looking to exploit the natural resources in its jungles to fund their operations.

The Nairobi-based charity WildlifeDirect, which publicized the latest killings, said Rwandan and Mai Mai rebels, Congolese army forces, and even local villagers were all to blame.

At least 17 elephants have been found butchered for their tusks since mid-April in Democratic Republic of the Congo's Virunga National Park, wildlife groups announced.

Beetle-ravaged forests prompt campground closures in Rockies

CHEYENNE, Wyo. - Vacationers will have fewer places to pitch their tents this summer in Colorado and Wyoming, and they can place the blame on bugs.

The U.S. Forest Service has closed some popular campgrounds in the two states because of concern that trees killed by the bark beetles that are ravaging forests across the West could topple onto unsuspecting visitors.

Dead bark beetles are displayed next to a penny in the Wyatt Williams's lab at Boise State University in Boise, Idaho, in this Aug. 24,2006, file photo. As bark beetles ravage millions of trees across the West, U.S. Forest Service officials in Colorado and Wyoming have closed some popular campgrounds out of concern the infested trees will come crashing down on visitors.

Bark beetles have always been a part of forests in the West, but warming temperatures and an abundance of aging lodgepole pines that haven't been thinned by fires have allowed populations of the hungry insects to explode. They now infest nearly 3,600 square miles of forest in the two states.

Sea lions shot dead on Columbia River as salmon battle rages

PORTLAND, Ore. - Six federally protected sea lions were apparently shot to death on the Columbia River as they lay in open traps put out to ensnare the animals, which eat endangered salmon. State and federal authorities are investigating.

The discovery came one day after three elephant seals were found shot to death at a breeding ground in central California.

A sea lion swims along the Columbia River, past Oregon Department of Fish and Wildlife investigators on Sunday, May 4, 2008 at Bonneville Dam, just east of Portland, Ore. The deaths of six sea lions are under investigation after the bodies of the federally protected animals were found in open traps on the Columbia River and appeared to have been shot.

Trapping will be suspended during the investigation, said Rick Hargrave, a spokesman for the Oregon Department of Fish and Wildlife who was at the scene Sunday.

The carcasses of the four California sea lions and two Steller sea lions were found Sunday around noon below the Bonneville Dam on the Columbia River on the border of Oregon and Washington.

Dwarf Cloud Rat Rediscovered After 112 Years

A team of Filipino and American scientists have rediscovered a highly distinctive mammal -- a greater dwarf cloud rat -- that was last seen 112 years ago. Furthermore, it has never before been discovered in its natural habitat and was thought by some to be extinct.

The greater dwarf cloud rat (Carpomys melanurus) was rediscovered in April, 2008 -- 112 years after the first and only time it had ever been seen by scientists. Cloud rats are one of the most spectacular cases of adaptive radiation by mammals anywhere in the world, with at least 15 species ranging in size from 2.6 kg to 15 grams, all living only in the Philippines.

The greater dwarf cloud rat (Carpomys melanurus) has dense, soft reddish-brown fur, a black mask around large dark eyes, small rounded ears, a broad and blunt snout, and a long tail covered with dark hair. An adult weighs about 185 grams.

"This beautiful little animal was seen by biologists only once previously -- by a British researcher in 1896 who was given several specimens by local people, so he knew almost nothing about the ecology of the species," said Lawrence Heaney, Curator of Mammals at the Field Museum and Project Leader. "Since then, the species has been a mystery, in part because there is virtually no forest left on Mt. Data, where it was first found."

UK: Rare albino ray is caught in the Solent

Trawlermen have landed an albino ray thought to be the first found in British waters.

The 80cm-long fish was caught in the Solent and is now being cared for at the Blue Reef Aquarium in Portsmouth.

Experts are surprised that the ray survived so long without camouflage to hide from predators.

Hundreds of Ducks Dead After Landing in Pond Owned by Canadian Oil Sands Company

Alberta's environment minister said the provincial government's efforts to allay environmental concerns about its booming oil sands industry will be hurt by the deaths of hundreds of ducks that landed on a pond filled with toxic waste.

Environment Minister Rob Renner concedes the deaths have put a dent in Alberta's efforts to counter the message being spread by environmental groups that Canada's oil sands projects are taking a toll on the environment.

Fruit bats at risk of extinction in Cyprus

The Fruit Bat is under threat of extinction on the island, the Forestry Department said yesterday. Forestry Officer Harris Nicolaou told the Mail that numbers have been rapidly declining, with only an estimated 3,500 remaining.

"We can say that numbers were far greater in the past and it is now an endangered species," he said.

Greece: Dead sea mammals mystery

An alarming number of dead sea mammals, apparently killed on purpose by humans rather than dying of natural causes, have washed up on Greek shores in the last few weeks, marine experts said yesterday.
