The 4th annual Frogs Are Green photo contest is now open for submissions. We hope you take your camera with you while you’re on vacation and get some great photos of frogs or other amphibians! Or you might take some great photos in your own backyard.

As in the past, we will be accepting submissions in two categories: Frogs in the Wild and Backyard Frogs.

Backyard Frog photos would include such photos as a frog perched on your picnic table or other unusual place. One year, for example, we received a photo of a frog sitting on a pool hose.

Frogs in the Wild photos, on the other hand, should feature frogs, toads, or other amphibians in their natural habitat: frog ponds, marshes, in the woods, and so on.

PLEASE—no photo manipulation and no photos of pet frogs. Please do not move the frog to get a better photo.

Photos of amphibians of all kinds, including salamanders, will be accepted.

This year we have a new contest area using Flickr, where you can enter yourself. You must add a caption/ description with your Name, Title and Location or your submission will not be added. For more information, please visit the contest page.There are three different group pools, two for photography so be sure to enter your photo into the right group pool.

Using "Frog Juice" to Enhance Racehorse Performance

According to a recent New York Times article, frogs and horses have recently been linked in a bizarre—and illegal—way. Evidently a compound found in the secretions of the waxy monkey tree frog (Phyllomedusa sauvagei) is being used to enhance the performance of racehorses.

The waxy monkey tree frog is native to South America. While most frogs like cool and moist places, waxy monkey frogs live in the Chaco (dry prairie) of Argentina, Brazil, Bolivia, and Paraguay. They seal in moisture with a waxy substance secreted through their skin glands. Living in trees, they draw in their arms and legs and sleep in the sun. At night, they awaken and hunt when the air temperature and the rate of water loss are lower.

The waxy substance in their skin contains a natural opioid called dermorphin, which is a more powerful painkiller than morphine. When injected into horses, it helps them run faster by dulling the pain from injuries. The substance has been found in more than 30 racehorses. According to the article, it is unclear where the substance is obtained, but it is probably artificially synthesized.

Abuse of horses seems to be rampant in horse racing. This use of “frog juice” is simply the most recent atrocity. In March, the New York Times ran another article titled “Mangled Horses, Maimed Jockeys.“

And, of course, this isn’t good news for the waxy monkey tree frog either.

Remarkable Frog Dads of Papua New Guinea

This is an updated repost of a Father’s Day post from 2009.

Most animal dads aren’t too involved with their offspring (human dads, excepted of course). But two species of frogs, Liophryne schlaginhaufeni and Sphenophryne cornuta, in the microhylid frog family are devoted dads, and in fact, carry their their brood of up to 25 froglets piggyback style through the rain forest of Papua New Guinea. The frogs were discovered by evolutionary biologist David Bickford.

While most frogs start their lives as tadpoles, these frogs undergo “direct development.” They bypass the tadpole stage and go straight from larvae to miniature versions of adults while still inside the egg. This is an adaptation that allows the frog to reproduce in regions without bodies of water nearby.

After the mother frog lays the eggs, she hops off while Dad watches over the clutch, warding off predators, and keeping the eggs moist for about a month.

After the froglets hatch from the eggs, they hop on Dad’s back. He carries them by night through the leaf litter in the rain forest. The froglets have a free ride until they grow up a bit and can live independently (hmmm…sounds familiar).

Learning about Nature in the Concrete Jungle

Recently we received an email from Kelly Rypkema, a New York area naturalist who is the producer and host of the video series Nature in a New York Minute. Kelly has just released an episode about the Amphibian Crossing Project in New Jersey, a volunteer-based effort to conserve amphibians in the Northeast.

In the Amphibian Crossing episode, we learn about the manmade obstacles that frogs, toads, and salamanders face each spring as they attempt to migrate, obstacles that threaten their very survival. Kelly joins a team of biologists and volunteers who are working to save these animals by taking matters into their own hands – literally.

If you’re a city dweller with an interest in nature around you, please take a look at Kelly’s site. For nature-oriented news and events, you can follow her on Twitter and Facebook or subscribe to her blog.

The Map of Life: Where in the World Are Frogs?

A research team involving Yale University and the University of Colorado Boulder has developed a first public demonstration version of its “Map of Life,” an ambitious Web-based project designed to show the distribution of all living plants and animals on the planet.

According to their press release, the demo version allows anyone with an Internet connection to map the known global distribution of almost 25,000 species of terrestrial vertebrate animals, including mammals, birds, amphibians, reptiles and North American freshwater fish.

The researchers compiled information about the animals from different sources: field guides, museum collections, and wildlife checklists from scientists, conservation organizations, and “citizen scientists.” They hope that scientists and informed amateurs will supply new or missing information about the distribution and abundance of particular species.

The Map of Life allows users to see several levels of detail for a given species — at its broadest, the type of environment it lives in, and at its finest, specific locations where the species’ presence has been documented. One function allows users to click a point on the map and generate a list of vertebrate species in the surrounding area. More functions will be added over time, according to the team.

“It is the where and the when of a species,” said Walter Jetz, associate professor of ecology and evolutionary biology at Yale and the project lead. “It puts at your fingertips the geographic diversity of life. Ultimately, the hope is for this literally to include hundreds of thousands of animal and plant species and show how much or indeed how little we know of their whereabouts.”

Eventually they hope that anyone, anywhere will be able to use their mobile devices to instantly pull up animal and plant distributions and even get a realistic assessment on the odds of encountering a particular species of wildlife.

The researchers  have created two video demos.

 

At Frogs Are Green, we think this will be a great project both as a learning tool (you can plug in a species name and get an overview of information about the species and where the species is found), but  it will also give scientists a tool to understand the biodiversity of a particular area.

Saving Frogs (and a Village) in Ireland

We recently received an e-mail from Laurence Stafford, who lives in a small village called Parteen in County Clare, Ireland. A highway is being proposed that will cut through his village, destroying the habitat of the Irish Common Frog (Rana temporaria).

Laurence’s e-mail highlights the problem of habitat destruction. What does it matter that frogs are losing their habitat in one small area of Ireland? Unfortunately this type of habitat loss is occurring across the globe: it is one of the reasons for the rapid worldwide amphibian decline. Of course, having a highway cut through a village will have enormous human costs as well.

The story is as follows: there is a joint venture between Limerick County Council and Clare County Council underway to build a highway costing over 352 million euros that will connect Galway to the University of Limerick. The highway will cut through Parteen village.

The Environmental Group of Parteen has warned the emerging preferred route crosses rural farmland, which is home to a protected species, Rana Temporaria. Although this species is fairly plentiful in Ireland, it is protected under an EU directive because of its declining numbers in Europe. The directive aims to protect some 220 habitats and lists approximately 1,000 species, including the frog.

This road will also divide a peaceful and tranquil village in two; the proposed volume of traffic is estimated at 20,000 to 30,000 cars, which calculates at 210,000 a month and 2,520,000 a year passing through a small community.

As reported in the Clare Champion, the group’s concerns are shared by Councillor Pascal Fitzgerald, who is disappointed with the planning of the new road, which he claims will divide settled communities and destroy their living environment: “Even people who have no connections with the area are asking why areas that have been ideal for living in are now to virtually have their heart cut out.”

We hope that the local county councils will rethink this route, both to preserve the frogs’ habitat – so important in this time of declining amphibian populations worldwide – but also to preserve the integrity of the village of Parteen.
