Native U.S. Lizards Adapting To Escape Attacks By Fire Ants

Fence lizards rely on camouflage to avoid being eaten.

Penn State Assistant Professor of Biology Tracy Langkilde has shown that native fence lizards in the southeastern United States are adapting to potentially fatal invasive fire-ant attacks by developing behaviors that enable them to escape from the ants, as well as by developing longer hind legs, which can increase the effectiveness of this behavior.

"Not only does this finding provide biologists with an example of evolution in action, but it also provides wildlife managers with knowledge that they can use to develop plans for managing invasive species," said Langkilde. The results will be described in a paper to be published later this month in the journal Ecology.

US: Palin does no favors for musk oxen

In her recent State of the State address, Gov. Sarah Palin invoked the image of musk oxen circling up to protect their young as a reminder that Alaskans, and Americans in general, need to stand together in these dire times.

This misleading and not at all "poetic" simile comes from the person who has appealed the polar bear's listing as threatened and plans to do the same with regards to Cook Inlet's beluga whales. It comes from the person who, though allegedly "pro-life," supports aerial-predator control and the killing of wolf cubs in their dens. It comes from the very same person who seeks to reinstall wolf bounties and allow drilling in the Arctic National Wildlife Refuge, the "place where life begins." Her naive comment resurrected from memory an experience I had while guiding wilderness tourists in the refuge a few years ago . . .

US: Disease shows up in area bat colony

A week before Christmas, DeeAnn Reeder and her colleague Greg Turner made a discovery in a cave in Mifflin County. A handful of bats hibernating for winter had the tell-tale sign of white-nose syndrome, a mysterious condition killing off colonies in the northeast.

The discovery of the white fungus confirmed what state, federal and academic researchers have suspected would happen: White-nose syndrome has arrived in Pennsylvania after being detected in New York and Vermont.

Parasites threatening California sea otters

The food some California sea otters eat might carry deadly parasites that come from cats and opossums, a recent study suggests.

Scientists from the University of California-Davis and the U.S. Geological Survey say some marine invertebrates on which sea otters feed can act as transport hosts for lethal pathogens that have made their way into the ocean, confirming a theory that has long been reported.

The risk of exposure to the pathogens is higher among sea otters when clams, fat innkeeper worms and marine snails are part of their diet, researchers said.

High Winds Kill 10 in Spain and France

Rescuers working Saturday after part of a sports center collapsed in high winds, killing four children.

Madrid - At least 10 people, including four children, were killed as high winds struck Spain and France on Saturday, tearing roofs from buildings, blowing down trees and power lines and whipping up huge waves.

The Spanish authorities said the four children were killed and several others injured near Barcelona on Saturday when the roof of a sports center collapsed in high winds. A spokeswoman for the Catalan government said the children had been sheltering from the wind in the sports hall in Sant Boi de Llobregat, just south of Barcelona, when the roof and some of the walls collapsed.

Jaume Bosch, mayor of Sant Boi, said the children were 9 to 12 years old, according to the Web site of La Vanguardia, a Barcelona-based newspaper. The spokeswoman, who spoke on condition of anonymity under government rules, said seven other children and two adults were injured, one of them seriously. Emergency services had pulled everyone free of the rubble of the building by midafternoon, she said.

Children among victims as deadly storm hits Europe

Three children are among several people to have died in extreme weather across parts of Western Europe.

It is reported the youngsters were killed when the roof of a sports centre near Barcelona collapsed in strong winds. In another incident in the same city a woman was fatally injured after a wall fell on her.

On the other side of the country, in the Galicia region, a policeman was killed when his car was struck by a falling tree.

One Whale Survives Mass Australian Beaching

A dead sperm whale on the north coast of Tasmania. Three more sperm whales from a group of almost 50 that beached en masse in Australia's south have died, with just two survivors sandwiched among the dead, rescuers have said.
Just one sperm whale from a group of almost 50 that beached en masse in Australia's south has survived, and remains sandwiched among the dead, officials said Saturday.

The pod of 48 whales became trapped this week on a sandbar 150 metres (500 feet) offshore from Perkins Island on the northwest coast of the island state of Tasmania. By the time they were discovered on Thursday almost all had perished.

High winds and ocean swell prevented rescuers from floating the two whales who survived through Friday night out to sea, and by late Saturday rescuer Warwick Brennan said just one was still alive.

"We didn't get a chance to get the whales out so we've just been trying to maintain them, keep them cool, but unfortunately one of them has died during the day so we've only got one alive now," Brennan told AFP.

Fatal Storms Hit Spain and France

Three children have been killed in northern Spain when the roof of a sports hall collapsed amid high winds, local officials say.

Two adults were also reported to have died in other storm-related incidents.

Torrential rains and winds of up to 172km/h (107mph) have been battering northern Spain and south-west France.

At least one million homes in France are without electricity, roads and railways have been blocked and airports ordered closed, authorities there said.

Residents in affected areas in both countries have been warned to stay indoors.

Magnitude 5.1 earthquake shakes Guatemala

A magnitude-5.1 earthquake has shaken northern Guatemala near the Mexican border, but there are no reports of injuries or major damage. The U.S. Geological Service says the quake occurred at 8:03 a.m. local time and was centered two miles (three kilometers) west-southwest of Huehuetenango city.
