Shocking pink tubes help to save albatrosses

Wandering albatrosses like this one are critically endangered, partly as a result of getting snagged on fishing lines, but a new scheme is changing that.

Gaudy strips of pink fluorescent tubing are helping to save albatrosses from extinction. They frighten the birds away from baited hooks on fishing lines, which attract, snag and drown some 100,000 albatrosses and petrels a year.

In South African waters in 2008, 85% fewer albatrosses died this way than a year earlier, thanks to the introduction of the pink strips on vessels fishing there for tuna and swordfish.

Flapping in the wind, the strips frighten the birds away from fishing vessels reeling out the lines.

"They form a visible deterrent and a no-go zone close to the bait and fishing gear as it's reeled out," explains Graham Madge of the UK Royal Society for the Protection of Birds, which co-launched the Albatross Task Force in 2006 with BirdLife International to stop albatrosses being snagged on hooks and drowning as they try to steal bait.

US: Quagga mussels are clogging Hoover Dam, colonizing lakes, rivers

Lake Mead, Nevada - It took some of America's best engineers, thousands of laborers and two years of around-the-clock concrete pouring to build the 726-foot-high Hoover Dam back in the 1930s. It took less time than that for the tiny, brainless quagga mussel to bring operators of this modern wonder of the world to their knees.

While federal lawmakers continue to squabble over how to stop overseas ships from dumping unwanted organisms into the world's largest freshwater system, the Great Lakes' most vexing invasive-species problem has gone national.

A U.S. researcher has used historic photographs as evidence of fishing's impact on marine ecosystems and the decline of "trophy fish."

Graduate student researcher Loren McClenachan of the Scripps Institution of Oceanography at the University of California-San Diego accessed archival photographs spanning more than five decades to describe an 88 percent decline in the estimated weight of large predatory fish imaged in black-and-white 1950s sport fishing photos compared with the relatively diminutive catches photographed in modern pictures.

"These results provide evidence of major changes over the last half century and a window into an earlier, less disturbed fish community ..." she said.

Japan snowstorm disrupts flights, damages houses

A snowstorm in Japan has damaged houses, caused power failures, disrupted train service and led to the cancellation of more than 150 domestic flights, local authorities said on Sunday.

About 40 centimetres (16 inches) of snow blanketed the runways at New Chitose Airport, the biggest air hub on the northern main island of Hokkaido on Saturday, an airport official said. At least 154 flights were cancelled.

A group of power company linemen work to restore high voltage lines Friday near the intersection of U.S. 129 and U.S. 441 south of Eatonton.
Ten tornadoes, one packing winds of more than 160 mph, touched down in parts of Georgia on Wednesday, the National Weather Service said Friday.

The storms caused an estimated $25 million in insured losses, said John W. Oxendine, the state's insurance commissioner.

"I spent some time surveying damage and talking to residents in Jasper, Putnam and Hancock Counties" on Friday, Oxendine said in statement. "I believe claims will easily reach $25 million. Actual losses are much higher when you consider things like infrastructure damage and uninsured losses."
