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.

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

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."

Horrific burns on Port River dolphins - the cause may never be known.
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.

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

A round goby.
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


The Casper Star-Tribune
Fri, 09 Apr 2010 16:11 UTC
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

A golden-spotted monitor lizard rests on a tree trunk in the Sierra Madre mountains, 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.

This bizarre creature dubbed the oriental yeti has baffled scientists after emerging from ancient woodlands in remote central China.
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."

It looks peaceful, but Laguna del Diamante's waters are deadly.
Argentinian investigators have found flamingos and mysterious microbes living in an alkaline lagoon nestled inside a volcano in the Andes. The organisms, exposed to arsenic and poisonous gases, could shed light on how life began on Earth, and their hardiness to extreme conditions may hold the key to new scientific applications.

In 2009, a team led by María Eugenia Farías, a microbiologist at the National Scientific and Technical Research Council in Tucumán, Argentina, discovered living stromatolites in the Socompa and Tolar Grande lagoons high in the Andes (see 'High window on the past'). Stromatolites - collections of photosynthetic microorganisms and calcareous concretions - are thought to have been common more than 3.5 billion years ago.

After that discovery, scientists in Argentina decided to look at lakes and lagoons in the Puna de Atacama, a desert plateau that sits more than 4,000 metres above sea level, in an attempt to understand what life might have looked like on the early Earth.

Corpse upon corpse they lie, a carpet of emaciated, fungus-ridden carcasses. Where once healthy animals hung in slumber from the cave roof, now there is a mass grave on the floor. It is a scene that is repeated throughout the eastern US, from Vermont to West Virginia. America's bats are in crisis, under threat from a mysterious killer.

Mysterious Whale Die-Off Is Largest on Record

Mass death among baby right whales has experts scrambling to figure out the puzzle behind the largest great whale die-off on record.

Observers have found 308 dead whales in the waters around Peninsula Valdes along Argentina's Patagonian Coast since 2005. Almost 90 percent of those deaths represent whale calves less than 3 months old, and the calf deaths make up almost a third of all right whale calf sightings in the last five years.

"This is the single largest die-off event in terms of numbers and in relation to population size and geographic range," said Marcela Uhart, a medical veterinarian with the Wildlife Conservation Society (WCS). She represents an associate director in Latin America for the WCS Global Health Program.
