U.S. Agency Proposes Legislation to Help Stem Spread of Chytrid Fungus

In an effort to stem the spread of the deadly chytrid fungus that is wiping out amphibian populations, the U.S. Fish and Wildlife Service (FWS) is considering banning the importation of amphibians and their eggs without a permit certifying the animals are disease-free. The chytrid fungus has caused the extinction of at least 200 amphibian species and continues to be one of the greatest threats to amphibians.

In a statement, Rowan Gould, Acting Director of the U.S. Fish and Wildlife Service, said,

The worldwide decline of amphibians is of great concern to us. Chytrid is attributed as a major cause of this amphibian mortality. We understand that halting the spread of the fungus or eradicating it will take more than just regulating importation and transportation of infected amphibians, but it is a major step in the right direction.

According the the FWS website, under the Lacey Act, the Department of the Interior is authorized to regulate the importation and interstate transport of wildlife species determined to be injurious to the welfare and survival of native wildlife. Current regulations prohibit the release into the wild of all species of live amphibians or their eggs, except as authorized. But, of course, this law isn’t easily enforced. Many pet frogs are let “free” in local ponds, potentially infecting native species.

A listing under the Lacey Act would not affect a person or institution that currently owns an amphibian and does not transport it to another state or U.S. territory.

At FROGS ARE GREEN, we applaud this proposed legislation and feel it would be a huge step toward controlling the spread of the chytrid fungus that threatens the survival of so many amphibian species, including native species listed under the Endangered Species Act.

The FWS is seeking input from the public. You can leave a comment until December 16, 2010. Please take a few minutes to comment and to show your support for a measure that will genuinely help amphibians.

Creating a Nature-Friendly Garden or Backyard – Guest post, Marlene A. Condon

We’re so pleased that Marlene A. Condon offered to share her expertise about creating wildlife-friendly gardens and backyards. Marlene is a nature writer and photographer with a passion for creating wildlife habitat around homes.  A field editor for Birds & Blooms since the magazine’s debut in 1995, she has been published in numerous newspapers and magazines and is the author of The Nature-Friendly Garden: Creating a Backyard Haven for Wildlife, Plants, and People (Stackpole Books).

With fall upon us, the majority of gardeners are thinking about cleaning up the garden and putting it “to bed.”  But this year, leave the garden alone.  Numerous kinds of wildlife are getting ready for winter.  Your hands-off attitude in autumn will benefit them and they will repay you next year when you begin a new gardening season.

The falling leaves that pile up along your garden fence create a haven where Gray Treefrogs and Spring Peepers can hibernate.  Next spring, as temperatures rise and these two kinds of treefrogs awaken, they will climb up into your trees and shrubs to feed upon insects and spiders.  Peepers, which usually stay within two to three feet from the ground, might also be found on your herbaceous (non-woody) plants.  But no matter where they feed, these amphibians help to limit the populations of invertebrates to numbers that your plants can sustain without incurring serious harm.

Some species of spiders and insects are taking refuge within your dying and drying garden plants to try to survive the winter in an inactive adult state.  Other species will soon perish, leaving behind eggs, larvae, or pupae on or within plants to carry on the line—if they survive the searching eyes of numerous predators still active in cold weather.

Watch your garden throughout the winter and you will see birds, such as Downy Woodpeckers and Carolina Chickadees, clinging to and poking your brown plants.  They are looking for the tiny insects and spiders, in whatever form, that provide our avian creatures with the fat and protein they require to survive the harshest time of the year.

If there are plants and food aplenty during the winter for them, birds that are permanent residents of the area may want to build nests next spring in your yard.  As winter comes to an end, you simply need to cut up the old plant stalks a bit and let them lie where they fall.  Many kinds of birds, such as Carolina Wrens, need such old stems, along with those dried leaves that sheltered the treefrogs, to construct their nests.

The dried plant material that the birds don’t take will be recycled into the soil for the benefit of your growing plants.  As snails and slugs become active, they will be delighted to find their favorite food (decaying plant and animal matter) waiting for them to feed upon.  When these unusual organisms are provided with such a fine smorgasbord, they don’t bother your growing plants.  Instead, they help to fertilize them—which is exactly what their function in your garden is supposed to be.

In other words, when you allow natural processes to occur as they are meant to happen, you don’t bring about the problems that most gardeners assume they are destined to encounter.  As numerous kinds of wildlife go about their everyday activities in your yard, they limit populations of other kinds of wildlife, thus eliminating overpopulations that are usually the sources of people’s gardening difficulties.

By creating a nature-friendly garden, you save money, time, and effort by not needing chemical pesticides.  By avoiding the use of pesticides, you don’t interfere with “Mother Nature’s” system of checks and balances that exists to keep the environment functioning properly.

You also don’t inadvertently harm wildlife that is not injurious to your plants.  Any insects or spiders poisoned by pesticides are easy prey for all of the other kinds of animals that feed upon them which means those critters can be poisoned as well.  And plants sprayed with herbicides pose an extreme danger to our helpful insect-eating amphibians, such as salamanders and toads, which have very absorbent skin.

Therefore, to avoid garden problems, help wildlife to survive in your yard.  You’ll get to enjoy the lovely songs and beauty of birds, the sights and sounds of numerous kinds of wildlife, and a more relaxed and thus more satisfying manner of gardening.

Text "FROG" and Help Save a Frog Today

Below is a re-post from the Panama Amphibian Rescue and Conservation project about their newly launched Text-Frog campaign to raise 50 K for their amphibian rescue program. We hope you will consider helping this worthwhile amphibian conservation effort by donating $5 via cell phone. See below for details.

YOU can help frogs!

The price we pay every time we lose a frog species to chytrid is too great to measure. The cost of saving frogs, however, is scant in comparison. But we need your help! That’s why we’ve launched a mobile giving campaign, providing an easy and convenient tool for you to help us battle chytrid and give the frogs a safe haven. Just pull out your cell phone and text “FROG” to 20222 to make a $5 donation to the rescue project.

Every $5 that comes in this way will go toward our new goal of raising the $50,000 it takes to turn a shipping container into a rescue pod. These rescue pods are biosecure “arks” where we can care for frogs that would otherwise be hit hard by the wave of chytrid. Without this ark, we won’t have a safe place to keep the frogs—so help us raise the funds by spreading the word!

So what will your money buy? Check it out:

$5: Three swab sticks used to test frogs for chytrid.
$5: A box of gloves to help ensure the cleanest and safest handling of the frogs.
$5: Pair of Crocs for keepers and visitors to change into to prevent bringing anything harmful into the biosecure rescue pods and areas where the frogs are kept.
$5: Small cricket container—caring for the frogs’ food is an important part of caring for the frogs.
$10: Four gallons of bleach, to keep the floor of the pod and quarantine rooms sterile.
$10: Large cricket container.
$10: Frog quarantine tank.
$15: Tub of yeast to feed fruit flies, which in turn are fed to the frogs.
$20: Calcium powder for frogs to keep them strong and healthy.
$20: Paper towel pack to help clean the tanks.
$30: 100 pounds of tilapia (fish food) to feed the crickets.
$30: Standard frog tank.
$150: Bottle of anti-fungal medication to treat the animals for chytrid.

Watch as our rescue pod fills up with frogs by following the progress of our $50K for Frogs campaign. And make sure to text “FROG” to 20222* to save a frog today! (You can text “FROG” to 20222 up to six times.)

*A one-time donation of $5 will be added to your mobile phone bill or deducted from your prepaid balance. Messaging & Data Rates May Apply. All charges are billed by and payable to your mobile service provider. Service is available on most carriers. Donations are collected for the benefit of the Panama Amphibian Rescue and Conservation Project by the Mobile Giving Foundation and subject to the terms found at www.hmgf.org/t. You can unsubscribe at any time by replying STOP to short code 20222; Reply HELP to 20222 for help. You can also find the privacy policy here.

City Dog, Country Frog

While canine bestsellers are common, a bestseller with a frog character is rare.  The picture book, CITY DOG, COUNTRY FROG by Mo Willems, with watercolors by Jon J. Muth, is currently No. 9 on the New York Times children’s book bestseller list.

CITY DOG, COUNTRY FROG. Words by Mo Willems, pictures by Jon J. Muth

The story is a simple one—a friendship blossoms between a dog visiting the country and a resident frog through spring, summer, and fall. When winter comes the dog searches for the frog, but can’t find him. And when spring comes around again, he realizes frog is gone. But country dog finds a new friend.

The story is something of a departure for Mo Willems, whose other books include the now classic Don’t Let the Pigeon Drive the Bus! In an interview, Willems says that he realized that he needed to find another illustrator for this story—Muth’s paintings complement the spare, poignant story perfectly. City Dog’s expressions of curiosity, playfulness, sadness, happiness, and confusion are sweet and tender—and very dog-like. Country Frog is pretty expressive, too!

Here’s a bit from the School Library Journal starred review by Joy Fleishhacker:

…[T] his tale depicts the natural cycle of friendship from an enthusiastic first encounter to contented companionship to the heartbreak of loss and eventual emotional renewal. Presented with a comfortingly consistent narrative structure, the events are set against the backdrop of the changing seasons, reassuring readers that winter will turn again to spring, sadness to joy…

As summer ends and we approach the first fall holiday, Rosh Hashanah, this is a wonderful book for kids about the cycle of seasons, change and renewal, friendship, and the importance of people or animals no longer with us.

One of the Smallest Frogs in the World Discovered

A pea-sized frog species, Microhyla nepenthicola, was discovered this past week in Malaysian rainforests on the island of Borneo. This miniature frog, measuring between 10 to 12 millimeters (less than one-half inch), is the smallest frog species discovered so far in Asia, Africa, or Europe. The tiny frog is a type of frog called a microhylid, composed of mini-frogs under 15 millimeters. The discovery was made by Drs. Indraneil Das of the Institute of Biodiversity and Environmental Conservation and Dr. Alexander Haas of Biozentrum Grindel und Zoologisches Museum of Hamburg.

The tiny frogs were found near pitcher plants, which grow in damp, shady forests. The frogs deposit their eggs on the sides of the globular pitcher, and tadpoles grow in the liquid accumulated inside the plant.

What is the world’s smallest frog? Two 9.8-mm-long amphibians in the New World—the gold frog in Brazil (Brachycephalus didactylus) and the Monte Iberia dwarf frog(Eleutherodactylus iberia) in Cuba are believed to be the world’s smallest frog species. They are about the size of a house fly—very tiny frogs indeed.

Back to School: Alternatives to Frog Dissection

Note: this is a rerun of last year’s frog dissection post, updated with new information.

Remember that scene from E.T. when Elliott frees all frogs in his science class? Elliott reminds me of my younger son Tim, who probably would have done the same thing (without being inebriated)!

This past weekend, Tim returned to college, where he is thinking of minoring in biology. He brought up an interesting issue: Would he be required to dissect an animal even if it is against his beliefs? Are alternatives provided for these students?

When I was a student, I didn’t have a choice. In both junior high and high school, I dissected a fetal pig. Each student had his/her own animal to dissect.

But with the rise of animals rights groups, PETA being the most visible, I wondered if times had changed. Do students have a choice? Are there alternative ways for students to learn about anatomy that don’t harm animals?

I discovered a site called Dissection Alternatives (Physicians Committee for Responsible Medicine) that explores these issues and offers lots of practical solutions. I was surprised to learn that research has shown that animal-friendly alternatives to teaching students about anatomy and biology are just as effective as the traditional methods of dissection. Computer software can now provide detailed, sophisticated graphics, interactive features, videos, and in-depth accompanying text to help students learn about anatomy.

I was also surprised to learn that the majority of medical schools often use these alternatives rather than traditional animal dissection. In addition, The National Science Teachers Association recently amended its official position statement on animal use, approving the use of non-animal alternatives as replacements for dissection.

Dissection Alternatives sponsors the Cut Above Awards, which honors teachers and students who have taken great leaps to adopt humane alternatives to dissection.

Dissection Alternatives provides information about the following:

PETA also created a site to address dissection alternatives called TeachKind, which is loaded with information, and includes a video demonstration of Digital Frog 2.5.
