FROGS ARE GREEN Earth Day Contest

I remember the first Earth Day forty years ago. I did a project with my friend Linda about endangered animals. Everyone in the entire school went outside on a gorgeous spring day to pick up garbage on the roads around the school. We were all so excited.

I think people forget that everyone was excited about Earth Day and about helping the environment then. The issue hadn’t become politicized. The country was united after the polluted Cuyahoga River went up in flames.

Both Democrats and Republicans in Washington supported and passed clear air and water regulations. These new tough laws were incredibly effective. When I was kid growing up on Long Island, you knew you were getting close to New York City because you could see and smell a layer of brown smog above the city. After these regulations were passed, the smog disappeared. Since the Reagan administration, however, tough regulations against corporations and businesses are taboo.

I wish we could recapture this bipartisan environmental effort. President Obama was elected partly because so many young people, motivated by environmental issues, voted for him. It didn’t matter if they were on the right or the left.

On the 40th anniversary of Earth Day, we’d like you to ignore the politics and recapture this excitement about preserving the environment and about enjoying and reconnecting to nature.

To that end, we’re sponsoring an Earth Day contest (open to all ages).  Please send us one simple practical idea by April 19th that we can all use to help the environment or reconnect with nature, guided by these words:

RENEW

REBUILD

RECONNECT

RETHINK

It doesn’t have to be a grand or complicated idea. For example, maybe someone can think of a way for people to remember to bring reusable grocery bags to the store. The winner, announced on Earth Day, will receive either the poster above or below (printed on FSC certified paper) or a 100% cotton t-shirt or onesie, made and printed in the U.S  (their choice):

Save the Frogs Day! April 30, 2010

Did you know that April 30th is Save the Frogs Day?

Save-The-Frogs-Day-Treefrog-328

Dr. Kerry Kriger, conservation biologist, founder, and Executive Director of the amphibian conservation organization, Save the Frogs, first conceived of and coordinated this event in 2009. The goal of Save the Frogs Day is to raise awareness about the global amphibian extinction, and to get people of all ages involved in amphibian conservation efforts. On his Save the Frogs website, Dr. Kriger has a powerpoint presentation that can be downloaded, lesson plans for teachers, and many other ideas for students to get involved.

You might consider putting up a display in your school or community center. Susan and I recently put up a display at City Hall in Hoboken, New Jersey, with frog books, drawings of frogs we’ve received from kids, illustrated posters, a poster about the global amphibian decline, and so on. So many people stopped to look at the display as we were putting it up. They were genuinely surprised to learn that amphibians were in such danger.

You can download our mission poster (seen above on the right and left in the display) or a poster of a rainforest tree frog in our store. We also have eco-bands made from 100% recycled silicone, other posters, and t-shirts (proceeds go toward Save the Frogs and Amphibian Ark ).

You may also want to throw a Save the Frogs Day party with fun frog-related party favors.

Please send us your event ideas or JPEGs of your Save the Frogs Day event and we will post them in a gallery on our blog!

First Monogamous Frogs Discovered

This past week the first monogamous frogs were discovered in the rainforest of South America. Monogamy isn’t usual in the amphibian world. Male frogs usually love ’em and leave ’em.

But Dr. Jason Brown, previously of East Carolina University, Greenville, North Carolina, and his colleagues, discovered a monogamous frog species Ranitomeya imitator, known as the mimic poison frog,

According to the BBC Earth News article, “Peru Poison Frog Reveals Secret of Monogamy,” after mating, a female mimic poison frog lays her eggs on the surface of leaves. After the tadpoles hatch, the male frog carries them one by one on his back to pools of water that collect in bromeliad leaves high up in the branches of trees. Each tadpole is put into its own tiny pool and the father looks after them. When the tadpoles become hungry, the male calls to his female partner who lays a non-fertile egg, which the tadpole eats, in each pool.

Why are these frogs monogamous and others aren’t? Scientists believe the mimic poison frogs have become mongamous as they evolved to live in small pools. The frogs wouldn’t have survived without the care of both mother and father because there is little natural food in these tiny pools. If the pools were bigger, there would have been more available food and the the frogs wouldn’t have to work together to feed and raise the tadpoles.

“These frogs are truly devoted to their offspring, and to each other,” says Dr. Brown, who is now at Duke University.

Wood Frogs Are (Almost) Celebrating Spring

In October, when we wrote our post Winter Turns Frogs into Frogsicles, the wood frogs and spring peepers had settled down for their long (frozen) winter nap. This blog post from The National Parks Traveler, Frogs are a Sure Sign of Spring, But that Doesn’t Mean You Won’t Hear Them Now, reminds us that even though it’s still winter (at least in the Northeast), it’s almost spring for the wood frogs. As the snow melts and the frogs unfreeze in late winter/early spring,  the young frogs have one thing on their minds: the males start calling immediately to potential mates.

I found this lovely video on YouTube by someone called Mysterious Susan (not our Susan though). It does have a mysterious quality as a reminder of the cycle of life.

Also, check out this blog post, “As Winter Wanes,”  in the East Hampton (Long Island, New York) Star about what songbirds, salamanders, and other animals are up to as we approach spring and the daylight hours get longer every day.

A Frog Love Shack

While humans may need flowers, chocolate, and a candlelit dinner to get in the mood for love, amphibians have quite different requirements. The Bristol Zoo Garden in England has designed what it calls the AmphiPod to encourage frog love. The zoo opened this special “love shack” to breed two endangered frog species—the Lemur Leaf frog and the Golden Mantella.

The mating chambers will provide a safe home for these frogs, which are listed as critically endangered on the IUCN Red List of threatened species.

In this BBC video Amanda Parr takes a look around the new facility with the Bristol Zoo’s Curator of Reptiles, Tim Skelton, giving her tour a Valentine’s Day spin.

As Skelton says of the project:

Until a solution is found to help stop the [chrytid] fungus in the wild, the safekeeping and captive management of threatened amphibians is the only way to ensure their long-term survival.

Our new AmphiPod will allow us to keep frogs in a safe, isolated environment, away from any threat of disease, as well as giving our keepers the opportunity to learn the techniques required for the specialist amphibian care we can provide in the AmphiPod. In future we will be able to provide a safe haven to other amphibian species in immediate danger of extinction.

However, the Zoo is still £30,000 short of the target amount which will help pay for the continued cost of running the facility for the next three years. For a Valentine’s gift with a difference, why not make a donation towards the Zoo’s “love shack”?

To find out how you can help, please see the Bristol Zoo Gardens website for more information.

Giant Salamander: Earth's Largest Amphibian

We confess to paying most of our attention in our posts on Frogs Are Green to the stars of the amphibian world—frogs—and not so much on other amphibians. So to make up for that, we’d like to introduce you to Earth’s largest amphibian—the giant salamander of China and Japan.

BB-Japanese-Giant-Salamander

This creature is considered a living fossil because it hasn’t changed much in 30 million years. To put things in perspective, 30 million years ago our ancestors were little primates hanging from trees. It would be millions of years before some of these primates descended from the trees, and millions of years after that before the first humans.

The giant salamander lives in mountain streams and lakes and can grow up to 6 feet long. It has four digits on its front legs and five digits on its back legs and is covered with a slimy protective mucous. It spends most of its time walking on the river bottom, though it can swim quickly. On land, its small legs won’t carry it and it must drag itself along.

Like many amphibians, the giant salamander is endangered due to habitat loss. Construction of dams converts  their free-flowing stream habitats into standing water or dries them up completely. They are also vulnerable to water pollution from mining activity and farming throughout their range.

Other threats to their habitat includes deforestation around the streams. This exacerbates soil erosion and causes increased runoff and siltation of the streams, reducing water quality and making it difficult for the salamanders to get enough oxygen through their skin. In addition, the giant salamander  is considered a delicacy and is also used in traditional Chinese medicine.*

On the BBC News site, Dr. Takeyoshi Tochimoto, director of the Hanzaki Institute near Hyogo in western Japan, gives a guided tour of this unusual creature.  (“Hanzaki” is the local name for the giant salamander.) After watching this video, however, I have decided not to hug a giant salamander if I ever meet one.  They have a very large mouth and several hundred small teeth on the top and bottom and can bite if angry, causing serious injury. Generally, however, this is a shy and secretive animal and is unfortunately relatively easy to catch.
