Some great news was reported during the past week here in Australia – the rediscovery after 30 years of the Yellow-spotted Bell Frog (Litoria castanea). Researchers from the Department of Environment, Climate Change and Water confirmed the sighting of the species in the Southern Highlands, south of Sydney.

Six tadpoles have been collected and have been taken to Taronga Zoo, where they will form the founders of what zoo staff hope will be a successful breeding program, eventuating in the release of captive-bred animals back to the wild. Taronga Zoo staff have been involved in serveal highly successful breeding programs for other amphibian species, including the Southern Corroboree Frog, Spotted Tree Frog,  Booroolong Frog, and the Green and Golden Bell Frog.

This discovery is really exciting news – something that is refreshing amongst the world-wide decline of amphibians. We mustn’t forget though, that amphibians around the world need our help to prevent further extinctions.

The Kihansi spray toad used to live in the spray region of the Kihansi waterfall, in Tanzania, and relied heavily on the spray from the waterfall to maintain a constant temperature and humidity in its environment. But due to the construction of a dam which funded by the World Bank, the waterfall has been disrupted, and the Kihansi spray toad has recently been declared Extinct in the Wild.

A number of small populations of this species exist in US zoos, and in spit of several setbacks with the initial population of 500 animals that were collected, the current population now sits at around 470 animals.

How many more species will become extinct in the wild, relying entirely on ex situ “ark” populations for their survival, before we start to take better care of our planet and ALL of its inhabitants?

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 –

It’s well chronicled that Panama’s amphibians are dying off because of chytrid (background on chytri click HERE). But there are steps that humans can take to slow the spread of chytrid as scientists search for a cure. Here’s a great article from Julie Ray of Examiner.com. In a nutshell, her advice is to take special steps to make sure your boots and wheels don’t accidentally spread chytrid after you visit an infected location.

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.
