The connection between frog deformities and pesticides and herbicides has been reported a lot. But here is a new study by Southern Illinois University in Carbondale that shows how little it really takes to harm amphibians. Imagine there was a pool of water in a farm pond that had the presence of only a trace (0.0000000003*) of pesticide ingredient edosulfan. That would be enough to kill half of the pond’s frog population. Take the 3 and make it 8, and every frog dies. Here’s the news release explaining the study:http://www.newswise.com/articles/view/555153/?sc=rssn (*Double check my decimal conversion. What I’m attempting to show is 0.3 parts per billion.)

An excerpt from the release:

The foothill yellow-legged frog is especially susceptible to the chemicals such as endosulfans, which kill by essentially overloading the nervous system and rendering breathing muscles useless. Europe and Australia each have banned the use of the chemical as a pesticide, and the U.S. Environmental Protection Agency also is studying the issue, Sparling said.

Sparling is optimistic humans can find ways to both farm on a large enough scale to feed the population and protect non-pest animals.

“To produce crops to provide for the world we have to use pesticides, and I’m not anti-pesticide,” he said. “But it’s important for us as scientists, agriculturalists and environmental protectors to make sure we continue developing pesticides that are as protective as possible of non-target animals as can be, both in the chemicals we use and application methods.”

You have to see this video from BBC showing tadpoles swarming their mom to feast on her infertile eggs. This rare glimpse is something you wouldn’t be able to see if it weren’t for the captive breeding programs of organizations to save endangered species. It’s all connected to the umbrella program of Amphibian Ark.

Excerpts from the story:

The remarkable footage was recorded at the Durrell Wildlife Conservation Trust, in Jersey, which took in 12 of the rescued frogs. Twenty-six others went to Parken Zoo in Sweden, and 12 are now housed in ZSL London Zoo.

“We thought that the eggs would come out and drop to the bottom of the nest and then the tadpoles would start eating them. But the footage shows about 40 tadpoles congregating around the female and eating the eggs as they come out of the female’s body.”

There are about 6,000 species of amphibians on the planet today. By the time we pass on and leave the world in our children’s hands, one-third to one-half of the species will have gone extinct. It’s projected by scientists to be the most significant mass extinction since the dinosaur. Maybe you’ve heard about this. Maybe not. But following is a straightforward accounting of the tectonic changes behind the massive, global disappearance of frogs, toads, salamanders, newts, and caecilians.  The way to act is to read up and help Amphibian Ark at www.amphibianark.org.

Chytrid, the AIDS of amphibiaChytrid is a fungal borne disease that is toxic to 80% of amphibian species. For thousands of years, it was confined to a section of Africa. The African Clawed Frog was one of the lucky 20% of species that was immune to the disease. But when the medical industry discovered African Clawed Frogs could be used as an ingenious pregnancy test for humans, they shipped the frogs out of Africa to all parts of the world. The species carried the Chytrid fungus with it, and the disease exploded. Most recently it has decimated the chicken frog population of Montserrat, and crossed the Panama Canal.

Watch for future posts that complete the five reasons:

Habitat destruction –

Pollution –

Global Warming –

Indifference –

Six years ago, promises were made by governments from around the world involving the mass extinctions facing so many animal classes, chief among them the amphibian class. The governments vowed to halt the decline in biodiversity by 2o1o. Well, the International Union for Conservation of Nature (IUCN) just issued a report that says, in essence, “let’s not kid ourselves, when next year comes around, it’s going to be bleak.”

IUCN, which puts out the Red List of most endangered species, has produced a 150-page report that details the loss of biodiversity earth has experienced over the last 5 years. “Biodiversity continues to decline and next year no one will dispute that,” said the report’s senior editor. “It’s happening everywhere.”

Here’s a link to story I just read about this.  (Click HERE.)

An excerpt from the IUCN Web site:

The report shows nearly one third of amphibians, more than one in eight birds and nearly a quarter of mammals are threatened with extinction. For some plant groups, such as conifers and cycads, the situation is even more serious, with 28 percent and 52 percent threatened respectively. For all these groups, habitat destruction, through agriculture, logging and development, is the main threat and occurs worldwide.

In the case of amphibians, the fungal disease chytridiomycosis is seriously affecting an increasing number of species, complicating conservation efforts. For birds, the highest number of threatened species is found in Brazil and Indonesia, but the highest proportion of threatened or extinct birds is found on oceanic islands. Invasive species and hunting are the main threats. For mammals, unsustainable hunting is the greatest threat after habitat loss. This is having a major impact in Asia, where deforestation is also occurring at a very rapid rate.

From the American Airlines in flight magazine, American Way, a full feature on the amphibian crisis. Here’s nice excerpt mentioning Amphibian Ark:

The idea of the Amphibian Ark initiative is to get out in front of the population crashes and to collect healthy frogs, whisk them to safety, and establish breeding stocks — with the hope of reintroducing the species to the wild when the coast is clear. In Australia, scientists have modified shipping containers to create frog “clean rooms” in the field. In the United States, they’ve saved the Wyoming toad in captivity, but it has disappeared from the high plains, and reintroduced populations keep encountering the deadly fungus. Biologists are also rushing to respond as the fungus attacks the boreal toad in Colorado and the red-legged frog in California’s Sierra Nevada. And many more frog rescues are underway in Costa Rica and several other countries.

Veronica from Bolivia just told me about a frog I hadn’t heard of before — Telmatobius culeus, or the Lake Titicaca frog.  This species has to deal with very thin oxygen high in the Andes, so mother nature has given it special characteristics. The following is excerpted from Livingunderworld.org. Note that the species is considered vulnerable and yet people are reportedly eating them.  Full article HERE.

Telmatobius culeus is referred to as the Lake Titicaca Frog, and is only found in Lake Titicaca. Because of the lower oxygen content in and around the lake, T. culeus must have an efficient method of obtaining the necessary amount of oxygen for survival. To do this, T. culeus respires mainly by means of cutaneous respiration (breathing through the skin), is exclusively aquatic, and possesses large folds of skin all over the body that make it appear flabby and prehistoric. The extra folds of skin increase the amount of oxygen absorbed through the skin because they increase the surface area to volume ratio; a characteristic that is also observed in other permanently aquatic amphibians. These frogs also do “push-ups” that create small disturbances in the water, which increases oxygen flow. The unique blood of T. culeus also aids oxygen absorption. The blood has the smallest erythrocytes (red blood cells) of all the amphibians, and the highest amount of hemoglobin. Hemoglobin are molecules in the blood that bind to oxygen, so the more hemoglobin an animal has, the more oxygen it can carry in the blood at one time. Because of their aquatic nature, these frogs have evolved reduced lungs, and rely almost entirely on cutaneous respiration.

Although classed as “vulnerable” with C.I.T.E.S., T. culeus are eaten in restaurants in Bolivia and Peru, and are a popular tourist dish. Recently, they have been collected for use in what the natives call frog juice, or Peruvian viagra. The frogs are literally put in a blender, and consumed.

Kevin Zippel from Amphibian Ark just emailed that the chytrid (Bd) fungus that chokes the breath from 80% of the world’s amphibian species it touches has landed in the Philippines. As you will read in THIS STORY, it’s been present for a least two years there. Five indigenous species are affected so far: the Luzon striped frog (Rana similis) has “practically disappeared from the lowland forests of Mount Labo on the southeast tip of the main Philippine island of Luzon”; the Luzon stream frog (Rana luzonensis); two species of the Luzon fanged frog (Limnonectes woodworth and Limnonectes macrocephalus); and the Puddle frog (Occidozyga laevis).
