Now I'm a chick! Gianni the gender-bending rooster starts to lay eggs, baffling scientists

Gianni started life as a red-blooded cockerel and would often wake his Italian owners up crowing on his farm in Tuscany.

But when a fox raided Gianni's enclosure and killed all of the hens inside, Gianni felt it was time for a change. Within days the bird was laying eggs and trying to hatch them as he began his new life as a hen.

The sex-change chicken has baffled scientists at the UN's Farm and Agriculture Organisation, who are now planning to study Gianni's DNA to see what made him change.

An expert at the centre said: 'It may be a primitive species survival gene. With all the females gone he could only ensure the future of his line by becoming female.'

Comment: Hmm...perhaps this sheds some light on this poor rooster's plight: "Scientists are warning that manmade pollutants which have escaped into the environment mimic the female sex hormone oestrogen" from Men under threat from 'gender bending' chemicals.

A 10-year-old Australian girl who survived being stung by the world's most venomous creature, the deadly box jellyfish, may have rewritten medical history, an expert said Tuesday.

Schoolgirl Rachael Shardlow lost consciousness after being badly stung by the jellyfish while swimming in a river in eastern Queensland state with her brother in December, but lived to tell the tale.

"When I first saw the pictures of the injuries I just went, 'you know to be honest, this kid should not be alive'," said Jamie Seymour, professor of zoology and tropical ecology at James Cook University.

"I mean they are horrific. Usually when you see people who have been stung by box jellyfish with that number of the tentacle contacts on their body, it's usually in a morgue," he told public broadcaster, the ABC.

Often deadly, the box jellyfish has long, trailing tentacles and is able to squeeze through even the smallest of nets as it is only the size of a fingernail.

Philippines: Elusive beaked whale stranded in Subic

Free Port - A rarely seen species of whale was stranded yesterday at the shoreline of Barangay Cawag in Subic, Zambales, the first time that such a stranding of an "elusive" deep-sea creature was documented in the Philippines.

The whale, a male specimen of the Blainville's Beaked Whale (Mesoplodon densirostris), was seen circling the area for two days, then ended up dead at the seashore on Wednesday morning, witnesses said.

Residents of sitio Matangib, located near the Hanjin shipyard at the Redondo Peninsula here, said they tried to push back the whale to deeper waters, "but it kept coming back to the shallows."

The stranding was documented by authorities from the Subic Bay Metropolitan Authority's Ecology Center, the local office of the Department of Environment and Natural Resources, and the Ocean Adventure Marine Park.

Dr. Leo Suarez, a marine biologist at the Ocean Adventure, said this was the first time for biologists to document the beaching of a Blainville's Beaked Whale in the country.

"This is certainly a rare sighting," Suarez said. "I believe this is the first time that a Blainville's Beaked Whale has stranded itself here in the Philippines."

He added that the cause of the stranding was not known, as the whale species is known to inhabit waters from 1,600 to 3,000 feet deep.

US: Beached whale's stomach found to be full of fresh trash

A gray whale's last meal in Puget Sound included plenty of trash, and it was fresh enough to indicate the animal took the "eat local" mantra enthusiastically to heart before coming ashore at Arroyo Beach, and later dying about a mile south of the Fauntleroy ferry dock.

A gray whale that came ashore and later died near the Fauntleroy ferry dock last week had all that is pictured here in its stomach, all ingested while feeding in Puget Sound.
Sweatpants. A golf ball. Surgical gloves. Small towels. Bits of plastic. And more than 20 plastic bags.

A gray whale's last meal in Puget Sound included plenty of trash, and it was fresh enough to indicate the animal took the "eat local" mantra enthusiastically to heart before coming ashore at Arroyo Beach, and later dying about a mile south of the Fauntleroy ferry dock.

In 20 years of examining more than 200 whale carcasses, research scientist John Calambokidis says Tuesday he has never seen so much trash in a whale's stomach. Founding member of the Cascadia Research Collective in Olympia, Calambokidis says he does not yet know what caused the whale's death, and tests are continuing.

"It kind of dramatizes the legacy of what we leave at the bottom," Calambokidis said. The sediment at the bottom of Puget Sound bays is loaded with other contaminants, "and an animal feeding and being exposed to this kind of garbage is also being exposed to those, too."

Australia: Global search can't solve Dolphin mystery

Injured Dolphins

The exact cause of the horrific burns inflicted on two Port River dolphins is unlikely to ever be known, despite a global search by local authorities.

The injured dolphins, Wave and her calf Tallula are being monitored daily by Port dolphin expert Mike Bossley and Adelaide Dolphin Sanctuary staff since the lesions on the upper flank of their bodies were first seen almost two weeks ago.

Dr Bossley, director of the Whale and Dolphin Conservation Society, said he was "more positive" about the dolphins likelihood of recovery, although the injuries were still a concern. "We've had responses from researchers and veterinarians from all over the world and it was universally acknowledged as the the worst ever injuries seen on a surviving dolphin," he said.

"I'm slightly more positive now that we've got to day 10 and they are still alive, because I feel if they were going to succumb they may have already by now.

"It would seem that Wave is feeding Tallula if Wave was too sick she couldn't provide milk but it is still a touch and go situation."

Environment Department animal welfare manager Deb Kelly ruled out any Port River industry or pollution as a cause of the burns.

However it wasn't possible to capture either dolphin to take skin samples to help determine the exact cause because it would be too distressing, she said.

Bee Populations Declining

North Liberty - Bee populations have been in decline for several years, and it's not just a national trend.

For Dave Laney, beekeeping is not only a hobby, but a family business. His warehouse in New Liberty is stocked with hundreds of bottles of honey.

"Even in these bad economic times, our business is hanging in there because people like good honey," Laney said.

To keep up with demand, Laney counts on the hard-working honey bees more than ever as populations continue to drop.

"We have a product in high demand," said Laney. "We're concerned to be able to get that product."

US: Invasive fish and mussels team up to transfer toxic substances into Great Lakes walleyes

Two notorious Great Lakes invaders -- the zebra mussel and the round goby -- now play a central role in transferring toxic chemicals called PCBs up the food chain and into Saginaw Bay walleyes, one of that region's most popular sport fish.

The links between zebra mussels, round gobies and contaminated Saginaw Bay walleyes is a disturbing example of unanticipated problems that can occur when non-native species get loose in the Great Lakes, said University of Michigan fishery biologist David Jude, lead author of a paper on the topic published online today in the Journal of Great Lakes Research.

"This zebra mussel-to-goby link in Great Lakes contaminated areas is one of the main conduits of PCB transfer to top aquatic predators such as the walleye, and it plays a substantial role in PCB transfer to birds, mammals and reptiles in the region as well," said Jude, a research scientist at the U-M School of Natural Resources and Environment.

Between 2005 and 2007, Jude's team collected walleyes, round gobies and various other fish species, as well as zebra mussels and zooplankton, in the Tittabawassee River, the Saginaw River and Lake Huron's Saginaw Bay. Then they measured levels of PCBs in all those organisms - the first such study in the Saginaw Bay region.

"Though the levels of PCBs in Saginaw Bay walleyes have declined sharply in recent years, these toxic substances continue to show up at levels high enough to warrant concern," Jude said.

US: Brucellosis in Wyoming elk on the increase

Green River -- Brucellosis appears to be increasing in several elk herds in northwestern Wyoming, according to a new U.S. Geological Survey study.

The study's data suggests that enhanced elk-to-elk transmission in free-ranging populations may be occurring because of denser elk clusters during winter.

The study also said that elk populations inside and outside of the Greater Yellowstone area that traditionally did not maintain brucellosis may now be at risk because of population increases.

The new study on brucellosis -- a bacterial infection of cattle, elk and bison -- appeared in the March publication of Ecological Applications, said USGS spokeswoman Suzanna Carrithers.

The magazine is a publication of the Ecological Society of America.

Brucellosis causes miscarriages in cattle. The disease is present in many elk and bison in the greater Yellowstone region, known as the last reservoir for brucellosis in the United States. The disease can be transmitted from wildlife to cattle.

The presence of the disease within livestock herds has resulted in additional testing requirements and trade restrictions in past years in both Wyoming and Montana.

Both states have had to institute strict testing and quarantine procedures to regain federal brucellosis-free status.

Paul Cross, USGS disease ecologist and lead author of the study, said elk-to-elk transmission of brucellosis may be increasing in new regions around Yellowstone.

He noted several cattle herds have been infected in Wyoming, Idaho and Montana since 2004.

Giant Lizard Discovered in the Philippines

Researchers have concluded that a giant, golden-spotted monitor lizard discovered in the forested mountains of the Philippines six years ago is a new species, according to a study released Wednesday.

The 6.5-foot (2-meter) -long lizard was first spotted in 2004 in the Sierra Madre mountains on the main island of Luzon when local researchers saw local Agta tribesmen carrying one of the dead reptiles.

But it took until last year to determine it was a new species. After capturing an adult, researchers from the University of Kansas and the National Museum of the Philippines obtained DNA samples that helped confirm the lizard was new to science.

The Northern Sierra Madre Forest Monitor Lizard or Varanus bitatawa feasts on fruits and snails rather than carcasses, unlike many monitors, including its larger relative, the Komodo dragon, according to American and Filipino researchers who wrote about the discovery in Wednesday's peer-reviewed Royal Society journal Biology Letters. It spends much of its time in the treetops and has unique claws that allow it to reach its favorite fruits.

A creature dubbed the 'oriental yeti' is being examined by scientists after emerging from ancient woodlands in remote central China.

The hairless beast was trapped by hunters in Sichuan province after locals reported spotting what they thought was a bear.

Hunter Lu Chin explained: "It looks a bit like a bear but it doesn't have any fur and it has a tail like a kangaroo."
