Nomura's jellyfish: The crew of the fishing boat was thrown into the sea when the vessel capsized, but the three men were rescued by another trawler
The trawler, the Diasan Shinsho-maru, capsized off Chiba as its three-man crew was trying to haul in a net containing dozens of huge Nomura's jellyfish.

Each of the jellyfish can weigh up to 200 kg and waters around Japan have been inundated with the creatures this year. Experts believe weather and water conditions in the breeding grounds, off the coast of China, have been ideal for the jellyfish in recent months.

The crew of the fishing boat was thrown into the sea when the vessel capsized, but the three men were rescued by another trawler, according to the Mainichi newspaper. The local Coast Guard office reported that the weather was clear and the sea was calm at the time of the accident.

Algae foam killing thousands of sea birds

Foam from an unusual algae bloom has killed thousands of birds along the Oregon and Washington coasts in recent weeks, marine biologists said.

Akashiwo sanguinea, a single-cell algae or phytoplankton, strips the birds of their natural waterproofing, said Julia Parrish, a marine biologist and professor at Washington State University.

"It's the largest mortality event of its kind on the West Coast that we know of," Parrish told The (Portland) Oregonian in a story published Friday. "We're getting counts of up to a million cells per liter of water," she said. "Think about that. That's pretty dense."

Storms have whipped the algae into a substance similar to a sticky soap, which washes off the birds' protective waterproofing oils and causes them to die of hypothermia, said Greg Schirato, a manager for the Washington Department of Fish and Wildlife.

'Gatorade for frogs' could stymie fungal killer

The fungus now decimating frog populations around the world does its damage by impairing the animals' ability to absorb electrolytes through their skin. This discovery may eventually lead to treatments that make the disease less lethal.

Biologists now generally agree that the fungal disease known as chytridiomycosis is responsible for the worldwide die-off of frogs that has caused a conservation crisis in recent years. However, the fungus affects only the outer layers of the skin, leaving few clues to why it is so lethal.

But now Jamie Voyles of James Cook University in Townsville, Australia, and colleagues have an answer. In diseased frogs, the skin's ability to take up sodium and potassium ions from the water decreases by more than 50 per cent, they found. As a result, the concentration of these two ions in the frogs' blood fell by 20 and 50 per cent, respectively. This ion loss - similar to the hyponatraemia that a human athlete might experience from drinking too much water too fast - eventually leads to cardiac arrest and death.

Hunting Banned in Parts of Austria After Hailstones Kill 90 Percent of Wild Game

Hunting has been banned in parts of Austria after freak storms with tennis ball-sized hailstones killed up to 90 per cent of the wild game population.

Sepp Eder, the hunting chief, said : "Animals sought shelter in farms, in fields of grain but the hail was so heavy it smashed right into them. It may take five years for animal numbers to recover, if they ever do so."

Farmers are believed to have suffered more than £60 million in damages to crops and buildings.

Hundreds of deer were discovered either dead or so badly injured they had to be put down by wildlife experts.

In the country's rural Salzburg province, 90 per cent of pheasants and 80 per cent of hares were killed in the hail storms.

More than 200 people have been treated for allergic reactions to the bites

A plague of mosquitoes affecting Torrevieja in recent days worsened over Friday and Saturday when more than 200 people were treated at La Loma health centre for allergic reactions to the insect bites. Diario Información reports that staff there were forced to send for supplies from other centres after running out of the medication they needed to treat their patients.

And La Verdad newspaper said local supermarkets and chemists have sold out of their stocks of insect repellents and insecticides.

Scientists say man-made noise equipment, including anti-seal sonar devices used in fish farms, is driving deep-water animals such as whales to shore, where they die.

A northern bottlenose whale was washed up dead on a beach in Prestatyn, North Wales, on Saturday morning, the tenth of the species to become trapped or stranded on British shores this year.

Scientists are blaming not just military sonar, but a large range of man-made noises that they fear are driving the normally deep-water animals to shore.

The week before, another of the 10m (33ft) whales became trapped in a small Scottish loch. Rescuers managed to push the distressed animal out of Loch Eil and halfway to safety but on Friday morning the whale was found dead.

Panama Butterfly Migrations Linked To El Niño, Climate Change

A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film - but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute.

"Our long-term study shows that El Niño, a global climate pattern, drives Sulfur butterfly migrations," said Robert Srygley, former Smithsonian post doctoral fellow who is now a research ecologist at the US Agricultural Research Service, the chief scientific research agency of the U.S. Department of Agriculture.

Climate change has been linked to changes in the migration of butterflies in North America and Europe but this is one of the first long-term studies of environmental factors driving long-distance migration of tropical butterflies.

For 16 years, Srygley and colleagues tracked the progress of lemony yellow Sulfur butterflies, Aphrissa statira, a species found from Mexico to Brazil, as they migrate across central Panama from Atlantic coastal rainforests to the drier forests of the Pacific coast.

A survey by the National Oceanic and Atmospheric Administration found that the number of beluga whales in Cook Inlet is again declining.
Anchorage Alaska - A government study found that a group of endangered beluga whales in Alaska is declining, raising concern that bolstered protection for the animals is not coming quickly enough.

The downward trend comes after two years where numbers for the Cook Inlet belugas appeared to have stabilized. But now numbers have slipped again to 321 animals, down from an estimated 375 animals in 2007 and 2008, according to figures released Tuesday by the National Oceanic and Atmospheric Administration.

The Cook Inlet whales, which swim mainly off Anchorage, are considered a genetically distinct population and don't mix with the other four beluga groups in Alaska.

The lower number in 2009 underscores the need for NOAA to act more aggressively to reverse the decline and save the whales from extinction, said Brendan Cummings, oceans program director with the Center for Biological Diversity, a group that has used legal pressure to try and get more protections for Cook Inlet belugas.

Excreted Tamiflu found in rivers

The premier flu-fighting drug is contaminating rivers downstream of sewage-treatment facilities, researchers in Japan confirm. The source: urinary excretion by people taking oseltamivir phosphate, best known as Tamiflu.

Concerns are now building that birds, which are natural influenza carriers, are being exposed to waterborne residues of Tamiflu's active form and might develop and spread drug-resistant strains of seasonal and avian flu.

For their new study, Gopal Ghosh and his colleagues at Kyoto University sampled water discharged from three local sewage treatment plants and water at several points along two rivers into which the treated water flowed. Sampling started early in December 2008, as flu season got underway. The researchers sampled again at the height of the seasonal flu's onslaught in early February and again as infection rates waned.

Whale forensics highlights threat to species

A high proportion of the whale meat on sale in Japan comes from a population of north Pacific minke whales that some fear is under serious threat.

The finding, from a forensic DNA study of meat bought on Japanese markets, suggests that either Japan's scientific whaling programme is taking more animals from this population than previously estimated, or accidental "by-catch" of the whales in fishing nets is larger than officially reported.

Vimoksalehi Lukoschek of the University of California, Irvine, and Scott Baker of Oregon State University in Newport, along with their colleagues, bought samples of whale meat in Japan and used DNA analysis to determine in each case not only the species of whale, but also which population it came from.

They found that a disturbingly high proportion came from a population of north Pacific minke whale that was selected for protection by the International Whaling Commission (IWC) in the 1980s, before the wider moratorium on commercial whaling came into effect.
