New Golden Frog Discovered In Remote Region Of Colombia

Posted by Miqe on August 29, 2007

Science Daily A new poisonous frog was recently discovered in a remote mountainous region in Colombia by a team of young scientists supported by the Conservation Leadership Programme (CLP). The new frog, which is almost two centimetres in length, was given the name the “golden frog of Supatá.”

Originally, the young scientists thought the frog was similar to several other common species in the area. However, after scientific analysis of the frog’s characteristics, and review of their findings by experts at Conservation International, it was determined that the golden frog of Supatá is unique and only found within a 20 hectare area in Colombia’s Cundinamarca region. Colombia is one of the world’s richest countries in amphibian diversity, with more than 583 species.

Unfortunately, since this frog is a recent discovery, and endemic to only the Cunidnamarca region, little is known about it. So far, scientists say that the golden frog of Supatá belongs to a group of “dart frogs” that are known to be highly venomous. In the coming months, the young scientists hope to have more information about the frog.

“The importance of this project is not just the discovery of the new frog,” said Oswaldo Cortes, team leader and one of the winners of the 2007 Conservation Leadership Programme awards. “But, most importantly, what this new discovery shows is how little we still know about our planet, and the many species that haven’t yet been discovered. This is why it is so important to work with local communities and educate them about the need for conservation.”

In addition to Oswaldo Cortes, the team of scientist includes Erika Salazar, Giovanni Chaves, Jose Gil, and Ximena Villagran, students, who attend La Universidad Distrital, and Francisco Jose de Caldas and Luiz Alberto Rueda of the University of the Andes (La Universidad de los Andes).

Swedish article about a man being bit. Livshotande bett av skallerorm

Posted by Miqe on August 23, 2007

En man i 25-årsåldern vårdas på sjukhus i Örebro för livshotande skador efter att ha blivit biten av en diamantskallerorm.

Mannen lyckades själv ta sig till Universitetssjukhuset i Örebro på tisdagen när han fått bettet av den mycket giftiga ormen, skriver Nerikes Allehandas nätupplaga. Tre av tio bitna som inte får behandling dör.

Det är som ett huggormsbett fast många gånger värre. Andningen, blodcirkulationen och njurarna hotas, säger överläkare Lars Berggren till tidningen.

Det serum mannen behandlades med fick skickas med iltransport från Stockholm.

Serumet kostar omkring 230 000 kronor, enligt NA.

Det handlar om en så kallad västlig diamantskallerorm. Det var på onsdagskvällen inte klart om ormen tillhörde mannen.

Wildlife Trust wants to hear about lizard sightings

Posted by Miqe on August 22, 2007

Have you ever seen a lizard? If so, the Irish Wildlife Trust want to hear from you.

Not many people in Ireland are aware that we have one species ,The Common Lizard (Lacerta vivipara) that is native to the island and has been here since the end of the last Ice Age, over 10,000 years ago. This lizard is about six inches in length and its colours vary between light green to almost black.

The Common Lizard, like all reptiles, is cold blooded, so it must get its energy from the sun. This is why they are often noticed basking on a stone or a log in sunny weather.

“We have had reports”, explained The Irish Wildlife Trust spokesman, ” from all types of habitats such as sand dunes, boglands, mountains and urban gardens. We are currently carrying out our third nationwide survey to determine just how common this lizard actually is.

“We depend on members of the public to report sightings to us and, we can then use this information to show where in Ireland they are more likely to be found”.

The Irish Wildlife Trust is also keen to hear important information about habitats, lizard activity at time of sighting, time of day etc to help give them a greater insight into perhaps Ireland’s least known native animal.

“So far the response from the public has been fantastic’, the spokesman went on, ” however, reports of lizards from Northern Ireland are rather scarce”.

If you, or anyone you know, has come across a lizard, please log onto the Trust’s website, www.iwt.ie. An online lizard report form can be found there. It only takes a few minutes to fill in. You can also contact the Trust through its email address - lizards@iwt.ie

Island home planned for lizard species and rescue bid for seagrass

Posted by Miqe on August 20, 2007

Eight species of lizards are to be relocated to a local island as part of a plan designed to improve the health of Whangarei Harbour.

The plan, funded by Marsden Pt port owner Northport Ltd through a 10-year, $500,000 Whangarei Harbour Health Improvement fund, also includes work to restore beds of undersea grass.

Friends of Matakohe/Limestone Island Society intend to transfer eight lizard species to the island off suburban Onerahi in Whangarei Harbour.

Northport’s fund is granting $10,660 to cover first-year costs of the three-year lizard relocation project.

Planning for the relocation has been going on for about 10 years and involves sourcing lizards from mainland and island sites before quarantining and testing them for diseases.

The reptiles will then be moved to Matakohe/Limestone Island.

The remaining $50,000 from this year’s harbour improvement funding will go to another ongoing project testing the best way to artificially restore seagrass in the harbour.

The Northland Regional Council’s Bruce Howse says thriving undersea meadows of seagrass once spread over about 1400ha of Whangarei Harbour before it died off due to sediment pollution which starved the grass of sunlight it needed to survive.

Only small pockets of seagrass remained in the harbour by the 1970s and it is now scarce.

But research in recent years by the National Institute of Water and Atmospheric Research (Niwa) has indicated that, with help, the seagrass might be capable of making a comeback.

Restoring even small areas of seagrass habitat would have a positive impact on the harbour’s ecological health because the grass serves as a nursery for juvenile fish and as a home to marine invertebrates, Mr Howse says. It also provides areas for seabirds to forage in.

Northport’s harbour health improvement fund was set up as part of resource consent conditions imposed when the company developed its deepwater port at Marsden Pt.

Squirrel Has Hot Tail to Tell Snakes

Posted by Miqe on August 15, 2007

Its infrared glow keeps rattlesnakes at bay

Squirrels are not as helpless as they may seem when confronted by rattlesnakes eager to make dinner of their pups. A new study reveals one of their most powerful tactics: the rodents heat their bushy tails and wave them back and forth to warn infrared-sensitive snakes they will not get fast food.

Infrared video showed that California ground squirrels’ tails warmed by several degrees, up to 28 degrees Celsius (82 degrees Fahrenheit), when threatened by northern Pacific rattlesnakes, which detect the infrared glow from small mammals using so-called pit organs in their noses. But no heating occurred while the rodents defended against gopher snakes, which lack such heat seekers, according to a report in Proceedings of the National Academy of Sciences USA.

Researcher has made the survival of endangered Lake Erie species her career, passion

Posted by Miqe on August 14, 2007

MIDDLE BASS ISLAND, Ohio — Armed with nothing more than courage and a Mickey Mouse pillowcase, Kristin Stanford scoured the banks for her “babies.”

With the sound of Lake Erie lapping against the shore, she found one and plunged her right arm up to her shoulder between two rocks, feeling with her fingers for Nerodia sipedon insularum.

Sometimes the Lake Erie water snake feels for her as well. With its teeth.

And once she’s got a grip on them, the snakes do what they do best in a tough situation.

They pee and poop on her.

It’s a dirty job, that’s for sure, but one that Stanford and others say is worth it.

Stanford, 30, is Lake Erie’s unofficial “snake lady.” At least that’s what locals have called her since she arrived on the islands just north of Port Clinton seven years ago.

Back then, when she was just starting her research, Stanford had never seen the species.

Now, she’s credited with helping save it.

“Thank goodness we’ve got Kristin,” said Carolyn Caldwell of the Ohio Division of Wildlife.

The division teamed up with the U.S. Fish and Wildlife Service, the Black Swamp Conservancy, Ohio State University and Northern Illinois University to protect the water snake, which in 1999 was listed as an endangered species in Ohio and a threatened species in the United States after its numbers dipped below 2,000. Stanford, a research associate at Northern Illinois University, studies everything about the snake, from digestion rates and eating frequency, to where it lives and how they affect the goby, a fish that makes up about 90 percent of its diet.

Stanford, who works out of Ohio State’s Stone Laboratory on Gibraltar Island, said the ill-tempered snake was losing habitat to development and was often hunted by people who saw it as a threat.

Today, scientists estimate that there are more than 7,000 Lake Erie water snakes on nine islands. And if things continue to improve, the snake could be removed from the endangered species list within three years.

“It would be a fabulous success story,” Stanford said.

Megan Seymour, a biologist with U.S. Fish and Wildlife, attributed the comeback to several factors, including restored habitat.

Officials have preserved more than 4.7 miles of island shoreline and 126 acres of inland habitat to protect the snake.

And, with Stanford’s help, more than 200 “water snakes welcomed here” signs have been given to island residents.

“Kristin has been key to our outreach and education program,” Seymour said. “She has a really great rapport with the citizens up there.”

If the Lake Erie water snake ever had a PR person, it is Stanford, who began studying the species for her master’s-degree project at Northern Illinois.

She has since made the project a full-time job while she performs her doctoral research.

Stanford catches snakes three days a week during the summer. In the field, she measures and weighs them and feels their rubbery bellies to see whether they are pregnant or have eaten recently.

She also tags snakes and has implanted radio transmitters in six to track their whereabouts.

She takes some back to the lab, where she makes them regurgitate to study what they ate.

The snakes, which can stretch as long as 3 1/2 feet, often are not cooperative. They pee on her, cover her in poop and bite her fingers, wrists and arms.

“It gets to the point where you’re doing it every day, all the time, you just don’t notice it,” Stanford said of the first two indignities.

“It’s more common than we want it to be.”

As for the bites, the snakes are not poisonous, but their pinlike teeth nearly always pierce her skin.

Stanford estimates she’s been bitten more than a thousand times.

On a recent hot, sunny gathering day, the snakes basked on the rocks as Stanford and three undergraduate research students arrived.

Depending on the terrain, researchers catch about a quarter of the snakes they find. (At the start of this day’s hunt, Max Castorani, an OSU undergraduate, crept in for the catch but lost the first snake in a crevice.)

At the end of the day, the group had captured and released more than a dozen snakes. Only one researcher reported a bite — a snake drew blood on his left wrist and a couple of fingers.

Between the blood, poop, pee and vomit, snake hunting is a dirty job. So dirty that Stanford was asked to be on the Discovery Channel’s hit show Dirty Jobs last year.

The show’s host, Mike Rowe, spent a day catching snakes with Stanford on South Bass Island, where the snakes welcomed him with open jaws.

“He got bit by every snake he caught except for the first one,” Stanford said. “That one crapped on him.”

Then they made the snakes bring up their prey so Stanford could study what they ate and how fast they digested the food.

The show’s success — it originally aired in November — has turned Stanford into an island celebrity of sorts.

A picture of Stanford, snakes in hand, is on an island kiosk, and she has received hundreds of e-mails from fans.

In one, a West Virginia man asked Stanford to marry him. (She’s married and politely declined.)

“It’s still completely bizarre to me,” said Stanford of her television success. “It’s just weird.”

That weirdness continues. Late last month, Dirty Job s fans voted Stanford’s episode among their top 10 favorites. Others included an exterminator, a pig farmer and a gentleman who tests shark suits.

The Discovery Channel flew the dirty jobholders to San Francisco to attend a party celebrating Rowe’s 150th job.

There, Stanford said, she met more fans.

“I just think it’s hilarious that people are so fascinated by me because I catch snakes and was on TV with Mike Rowe,” she said.

“It’s really strange.”

Some, however, would say grabbing snakes — poop, vomit, teeth and all — is a tad strange in itself.

Baby lizard-like Tuatara found on NZ

Posted by Miqe on August 13, 2007

After nine years New Zealand scientists are excited by the unexpected hatching of a baby tuatara - a native reptile so rare it’s in danger of becoming extinct.

The discovery of the lizard-like creature has proved tuatara are breeding on Matiu/Somes Island in Wellington Harbour - with one baby hatching last week and a sibling possibly on its way.

The baby tuatara came from an egg found on the island and is the first known offspring of 54 Brothers Island tuatara transferred to the island nine years ago.

There may be a sibling to follow - the egg was one of two taken from a buried nest on the island in May to be incubated at Victoria University school of biological sciences.

The Department of Conservation (DOC) and tuatara experts from the university had long suspected the island’s “robust and healthy” tuatara were breeding, but are happy to now have proof.

The tuatara is a reptile, not a lizard, and is particularly significant because it is the last remaining member of the ancient group of reptiles, Sphenodontia.

Tuatara is a Maori word meaning “peaks on the back” and the creatures resemble lizards, but are equally related to snakes.

The reptiles lead secretive lives, burying their tiny eggs in the ground, so there was no tangible evidence until the chance discovery of eggs beside a track on the island.

“The island ranger found two eggs which appeared to have been scratched from a burrow by another tuatara,” DOC biodiversity program manager Peter Simpson said.

“We would have been surprised if they hadn’t been breeding, but their buried nests are usually well concealed.”

Experts were quickly alerted and a probe of the burrow revealed six more eggs, two of which appeared to be viable. They were carefully monitored by Victoria University staff, who were thrilled to discover a fully formed, miniature tuatara had emerged from the egg last Wednesday.

Its sex has yet to be determined.

“We’ve been waiting for this for nine years. It’s fantastic,” said researcher Sue Keall.

The tuatara will be returned as soon as possible to join others in the wild on Matiu/Somes Island, a DOC-managed historic and scientific reserve.

“We’ll look after it until it gets more robust but in nature parents desert the eggs in the nest as soon as they are laid. And from the moment they hatch, tuatara are very active and quick, and well able to fend for themselves,” Ms Keall said.

“We’re all very excited.”

Beheaded Snake Sends Man to Hospital

Posted by Miqe on August 10, 2007

PROSSER, Wash. — Turns out, even beheaded rattlesnakes can be dangerous. That’s what 53-year-old Danny Anderson learned as he was feeding his horses Monday night, when a 5-foot rattler slithered onto his central Washington property, about 50 miles southeast of Yakima.

Anderson and his 27-year-old son, Benjamin, pinned the snake with an irrigation pipe and cut off its head with a shovel. A few more strikes to the head left it sitting under a pickup truck.

“When I reached down to pick up the head, it raised around and did a backflip almost, and bit my finger,” Anderson said. “I had to shake my hand real hard to get it to let loose.”

His wife insisted they go to the hospital, and by the time they arrived at Prosser Memorial Hospital 10 minutes later, Anderson’s tongue was swollen and the venom was spreading. He then was taken by ambulance 30 miles to a Richland hospital to get the full series of six shots he needed.

The snake head ended up in the bed of his pickup, and Anderson landed in the hospital until Wednesday afternoon.

Mike Livingston, a Washington Department of Fish and Wildlife biologist, said the area where the Anderson’s live is near prime snake habitat. But he said he had never heard of anyone being bit by a decapitated snake before.

“That’s really surprising but that’s an important thing to tell people,” he said. “It may have been just a reflex on the part of the snake.”

If another rattlesnake comes along, Anderson said he’ll likely try to kill it again, but said he’ll grab a shovel and bury it right there.

“It still gives me the creeps to think that son-of-a-gun could do that,” he said.

Genetic analysis conducted on frog fungus

Posted by Miqe on August 10, 2007

 

BERKELEY, Calif., Aug. 9 (UPI) — A genetic analysis of a deadly fungus decimating U.S. yellow-legged frogs in the Sierra Nevada Mountains shows it spreads by sexual reproduction.

The dramatic decline of the frogs has been attributed to the introduction of non-native predatory fish in some areas and to chytridiomycosis, a quickly spreading disease caused by the waterborne fungus Batrachochytrium dendrobatidis.

The new study — led by the University of California-Berkeley — suggests the fungus might have a more significant role in the frogs’ demise than had been thought because of the pathogen’s ability to spread over long distances and possibly persist in the environment through sexual reproduction.

“This group of fungi, when it reproduces sexually, can create spores that can last for a decade,” said Professor John Taylor, the study’s principal investigator. “That could make this pathogen a harder problem to defeat.”

The findings might also help explain the global spread of the pathogen, which has also been found in South America, Australia, Europe and Africa.

The findings are to appear in next week’s issue of the Proceedings of the National Academy of Sciences.
