Yasuni National Park, Ecuador: An Amphibian Eden

Yasuni National Park

Scientists have recently identified Yasuni National Park in Ecuador as one of the most biologically diverse places in South America, and perhaps on earth. As Shawn McCracken of Texas State University—San Marcos, recently said, “The 150 amphibian species throughout Yasuni is a world record for an area this size. There are more species of frogs and toads within Yasuni than are native to the United States and Canada combined.”

Unfortunately this Eden sits on oil reserves and is threatened by proposed oil development projects. McCracken and other scientists from Ecuador, the United States, and Europe have proposed a moratorium on new oil exploration until the effects of such projects can be explored.

Reading about this, we couldn’t help but think about the movie Avatar and the attempted destruction of the planet Pandora to mine unobtanium. Unfortunately, we humans aren’t as wise as the Na’vi—yet. Let’s hope that Ecuador will preserve this incredible pocket of biodiversity and not be so shortsighted as to destroy parts of it for oil.

A Field of Nightmares? Atrazine, Corn, and Frogs

I’ve always had a sentimental attachment to cornfields—from the magical cornfield in Field of Dreams to the real cornfield across the road from a house I lived in during college years. My mother was born and raised in Iowa and I’m descended from farmers.

But chemicals, in particular Atrazine, used as herbicides on cornfields might be poisoning frogs (and people), and turning fields of dreams into fields of nightmares.  These herbicides run off cornfields into streams and rivers, and leak through the water-treatment process, contaminating groundwater and drinking-water supplies.

Last summer we blogged about the problems of Atrazine. Research by University of California, Berkeley professor  Dr. Tyrone Hayes, for example, has shown the effects this chemical—an endrocrine disruptor—has on frogs. It can cause birth defects and reproductive problems, including such bizarre deformities as male frogs with eggs in their testes. This past week, as reported in the Washington Post, new research at the University of Ottawa found that when exposed to Atrazine fewer tadpoles reached froglet stage. Atrazine appears to affect estrogen in humans as well and has been connected with ferility problems, cancer, and birth defects.

The EPA, under the Obama administration, has launched a review of the chemical that will continue until fall 2010. It will look closely at Atrazine and other endrocrine disruptors, which might result in tighter restrictions on their use. While this sounds hopeful, Atrazine’s primary manufacturer, Syngenta, has strong ties and influence within the EPA. (Atrazine is banned in Europe, where perhaps industry and government aren’t as closely intertwined as they are in the U.S.).

The Froglog: A Frog-Friendly Invention

Last summer we received a wonderful photograph taken by Mary Lascelles for our photo contest of a frog (whom she named Fritz) who hung out on the filter line in her pool sunning himself. Luckily, Fritz never fell in the pool.

Unfortunately many frogs do fall in pools and are poisoned by chlorine, which is absorbed into their bloodstream through their permeable skin. Recently on the Mother Nature Network blog, I read about a new invention, called a froglog, that helps frogs and other small animals escape from pools.

The froglog was created by Rich Mason, a wildlilfe biologist with the U.S. Fish and Wildlife Service, who was disturbed that so many frogs and other animals were dying in pools. The froglog is a thick foam tile with angled edges that allow frogs to climb out of the pool. The froglog can also be used in hot tubs, spas, fountains, and backyard ponds.

As Mason writes on his website, due to suburban sprawl, pools are now often built close to the natural habitats of amphibians. He mentions a friend with a pool in Maryland who found over 50 animals trapped in his pool in one night.

Check out this video of frogs and turtles using the froglog escape ramp. And if you have a pool and live in an area with lots of wildlife, definitely consider getting a froglog!

Pet Frogs Associated with Recent Salmonella Outbreak

Yesterday we received information from the American Veterinary Medical Association that about 80 people in 28 states have now become ill in a salmonella outbreak associated with pet frogs. More than three-quarters of the illnesses involved children younger than 10.

Bacteria matching the outbreak strain were found in aquariums that contained aquatic frogs. The Center for Disease Control and the Utah Department of Public Health (the site of at least 6 cases) are investigating animal distributors and vendors as possible sources of the outbreak.

Symptoms of Salmonella include: diarrhea, fever, and cramps 12-72 hours after the infection enters the body. The infection persists four to seven days and even longer for infected individuals with weaker immune systems.

People who should make explicit efforts to avoid contact with the animals are children, especially those younger than five years old, elderly people, and people with weak immune systems.

Given the findings, the Central for Disease Control advises the following:

  • Amphibians should not be kept in child-care centers.
  • Habitats containing amphibians should not be kept in a child’s bedroom, especially children aged less than 5 years.
  • Do not allow amphibians to roam freely through the house, especially in food preparation areas. Keep amphibians out of kitchens and other areas where food and drink is prepared or served to prevent contamination.
  • Habitats and their contents should be carefully cleaned outside of the home. Use disposable gloves when cleaning and do not dispose of water in sinks used for food preparation or for obtaining drinking water.
  • Do not bathe animals or their habitats in your kitchen sink. If bathtubs are used for these purposes, they should be thoroughly cleaned afterward. Use bleach to disinfect a tub or other place where amphibian habitats are cleaned.
  • Children aged less than 5 years should not clean habitats.
  • Always wash hands thoroughly with soap and water after cleaning habitats.

Aquatic frogs, such as the African Dwarf frog, are the frogs sold in Brookstone’s Frog-O-Sphere kits and other kits. This salmonella outbreak is another good reason to avoid these live frog kits.

Pacific Chorus Frogs Spend the Holidays in Alaska

This holiday season, some Alaskans found “live” ornaments on their Christmas trees—Pacific Chorus frogs that hitchhiked in the trees to Alaska.

Unfortunately, these little stowaways were not warmly received by the Alaska Department of Fish and Game. They are considered invasive species as they might carry fungi and viruses that could harm native frog species.

I imagine these frogs would be happier if they were sent home. Pacific Chorus frogs are native to Pacific coastal areas from Baja California up to Washington State. According to Lang Elliott in The Frogs and Toads of North America, its familiar two-part call, rib-bit, is the one most associated with frogs because they have provided the background “music” for so many Hollywood movies and TV shows.

Here’s the call of the Pacific Chorus frog in its native habitat—far from Juneau.

A Frog's Dream…Save Our Home

As the year ends, and before we take a short break for the holidays, we’d like to show you the new poster we’ve created to promote our cause. Proceeds from the sale of the poster will go toward amphibian conservation organizations and toward developing free and inexpensive educational materials for kids.

The poster is a unique collaboration between my partner Susan (who is a graphic designer when she isn’t saving frogs) and illustrator Sherry Neidigh. Sherry approached us after seeing our blog and offered to donate one of her illustrations for our use. We were thrilled to receive this exquisite illustration to promote our cause.

Susan played around with various ideas, but what struck her about this illustration was its dreamy quality. She came up with the text, “A Frog’s Dream….Save Our Home.” I think these words are perfect. That frog looks so content immersed in his pond, surrounded by dragonflies and lily pads.

A bit about Sherry:

Sherry has been drawing animals since she was 2 years old. She attended the Ringling School of Art and Design in Sarasota, Florida, and has worked for Hallmark Cards.

Sherry’s clients include the National Wildlife Federation (Your Big Backyard), Highlights for Children, Sylvan Dell Publishing, and NorthWord Publisher. She works in gouache, watercolor, colored pencils, airbrush, and pen and ink. Her latest book is Count Down to Fall by Fran Hawk, published by Sylvan Dell Publishers. Sherry lives in Simpsonville, South Carolina, outside of Greenville, with her two dogs, Harper and Bisbee. You can learn more about her by visiting her charming website.

Susan and I are so grateful for the use of Sherry’s beautiful illustration. We hope you love the poster as much as we do. Susan also designed a t-shirt with the illustration. Both are available in our store.

Happy Holidays!
