Frogs & Football: The Horned Frogs

At this time of the year, while frogs and toads are deep in hibernation (in our part of the world anyway), our Google alerts for frog news are full of stories about Horned Frogs, not the frog species, but rather the sports teams. Not being much of a sports fan, I always ignore these stories. But this year, we finally decided it was time to learn a little about these Horned Frogs.

It turns out that the Horned Frogs are the 18 varsity athletic teams that represent Texas Christian University. The Horned Frog mascot first appeared in 1897, and by 1915, it appeared on the TCU seal. During the post-WWII years, the Horned Frog mascot was in costume, on stationery, class rings, and the band’s bass drum. In 1979 the mascot was renamed from Addy the All-American Frog to Super Frog.

The women’s teams are known as the Lady Frogs. TCU once had a bumper sticker that said “My Princess Turned into a Frog.”

But This Horned Frog is Actually a Lizard!

It turns out, however, that the “horned frog” nickname and mascot refers to the Texas horned lizard, also known as the “horned frog.” The popular name comes from the lizard’s rounded body and blunt snout, which gives it a toad- or frog-like appearance. The Texas horned lizard, along with at least three other species of horned lizard, has the ability to squirt an stream of blood from the corners of the eyes and sometimes from its mouth for a distance of up to 5 ft (1.5 m).

Some Native American peoples regard horned lizards as sacred—the animal is a common motif in Native American art of the Southwestern U.S. and Mexico. The Texas horned lizard is also the state reptile of Texas.

Go Frogs!

So before the football season is officially over this Sunday, we thought we’d introduce you to one of the TCU teams, the Horned Frogs football team. It competes as a member of the Mountain West Conference, but is due to move to the Big East Conference for the 2012 season. The Frogs have won two national championships and 15 conference championships. Legendary players include Bob Lilly, Sammy Baugh, Davey O’Brien, and LaDainian Tomlinson.

The Horned Frogs won the 2011 Rose Bowl, beating Wisconsin, 21-19.

And if you’d like to learn about the real Horned Frogs (the amphibians, not the lizards), check out our 10 Weirdest and Most Unusual Frogs post, which introduces the Ornate Horned Frog. We were so entranced with this frog that Susan created a poster about it (proceeds to benefit amphibian conservation).

Brookstone to Discontinue Frog-O-Sphere kits

We were happy to learn that Brookstone has decided to remove the Frog-O-Sphere kit from its shelves.

In previous posts we’ve blogged about why we were against this product. Others have protested against the kits as well, most notably PETA, which organized thousands of calls and e-mails to Brooksone, as well as appearances of a giant frog outside the Brookstone headquarters to protest the kits. After 18 months of protests, Brookstone has decided to discontinue the Frog-O-Sphere kit.

Brookstone joins Magic Beans, Target, and other retailers that have stopped selling these kits, but according to PETA, Coach House Gifts is still selling frogs in “EcoAquariums.”

Why did we think these kits were so bad? Unfortunately, the promise of a true ecosystem was their selling point, but this promise was overstated. The kit was meant to more or less take care of itself, the snail eating the algae, and so on. But the snails frequently died so a key part of the “ecosystem” fell apart. As with any pet, it takes more than a simple gimmick, and usually a lot of work, to keep the pet healthy and flourishing. In many cases these frog kits were bought as decorations for offices or as spontaneous gifts for a child. Once the novelty wore off, the frogs languished. Of course, this can happen with any pet, but because the frogs were not bought in pet stores, buyers did not receive instructions on the proper care of the frogs. In addition, many frogs died on the store shelves or while being shipped across the country.

We haven’t kept frogs as pets and generally don’t recommend it. In some cases, the frogs may be collected from wild populations (not the case with African Dwarf frogs). Pet frogs, especially from these types of kits, may be “let free,” which often happens at the end of a school year for a classroom frog grown from a kit,  or when a child gets bored with it. These “free” frogs can wreak havoc on native frog populations by spreading disease.

If you purchased a Frog-O-Sphere, we highly recommend you learn about how to take care of your frog properly. We’ve included some links below. If you are experienced in the care of African dwarf frogs, please help us out by sharing tips in the comments.

Rediscovering Haiti's Lost Frogs

Haiti recently marked the anniversary of the January 12, 2010, earthquake that devastated the country, killing over 300,000 people, and leaving almost a million people homeless.

Recently scientists from Conservation International (CI) and the Amphibian Specialist Group (ASG) of IUCN reported a bit of news they hope might become a source of pride and hope for the country’s environmental future: the surprising re-discovery of six species of  frogs in the country’s severely degraded tropical forests, species that had been lost to science for nearly two decades.

Large-scale deforestation has left the country with less than two-percent of its original forest cover and has degraded most of the fresh water ecosystems. Yet Haitians depend on the cloud forests of the southwest mountains as two of the last remaining pockets of environmental health and natural wealth in Haiti.

This expedition was part of Conservation International’s global Search for Lost Frogs campaign, in which CI’s Amphibian Conservation Specialist Dr. Robin Moore, in partnership with Dr. Blair Hedges of Pennsylvania State University, searched for the La Selle Grass frog (E. glanduliferoides), which had not been seen in more than 25 years. They also hoped to assess the status of Haiti’s 48 other native species of amphibians.

The scientists did not find the La Selle Grass frog, but to their surprise, they rediscovered several other remarkable frog species, most of which haven’t been seen since 1991. As Dr. Moore says, “We went in looking for one missing species and found a treasure trove of others. That, to me, represents a welcome dose of resilience and hope for the people and wildlife of Haiti.”

Dr. Moore says that a common assumption about Haiti is that there isn’t anything left to save. Yet this is not true. According to Moore, there are biologically rich pockets intact, despite tremendous environmental pressures. Haiti now has the opportunity to design their reconstruction plans around these pockets, and to protect them, so that these natural areas can more effectively act as buffers to climate change and natural disasters. However, there is little time to waste: 92 percent of Haiti’s amphibian populations are listed as threatened and are in danger of disappearing.

“The biodiversity of Haiti, including its frogs, is approaching a mass extinction event caused by massive and nearly complete deforestation. Unless the global community comes up with a solution soon, we will lose many unique species forever,” said Dr. Hedges.

Amid the backdrop of Haiti’s struggle to rebuild, Moore added some important context:

The devastation that the people of Haiti are still coping with is almost unimaginable. I have never seen anything like it. Clearly, the health of Haiti’s frogs is not anyone’s primary concern here. However, the ecosystems these frogs inhabit, and their ability to support life, is critically important to the long-term well-being of Haiti’s people, who depend on healthy forests for their livelihoods, food security, and fresh water. Amphibians are what we call barometer species of our planet’s health. They’re like the canaries in the coal mine. As they disappear, so too do the natural resources people depend upon to survive.

Here are a few of the rediscovered frogs:

Hispaniolan Ventriloquial Frog (Eleutherodactylus dolomedes). This frog is named after its call that the frog projects like a ventriloquist. Its unusual call consists of a rapid seven-note series of chirps, with the initial four notes rising slowly in pitch before plateauing; the call is released in widely-spaced intervals, often minutes apart. Prior to this expedition, the species was only known from a few individuals.

Mozart’s Frog (E. amadeus). Called Mozart’s frog because when Dr. Hedges, who discovered the species, made an audiospectrogram of the call, it coincidentally resembled musical notes. Its call is a four-note muffled whistle at night; usually given as a shorter two-note call at dawn and dusk.

La Hotte Glanded Frog (E. glandulifer). This frog could be called Old Blue Eyes: its most distinctive feature are its striking blue sapphire-colored eyes – a highly unusual trait among amphibians.

Macaya Breast-spot frog. (E. thorectes). Approximately the size of a grape, this is one of the smallest frogs in the world. In Haiti, this species has a very restricted range, occurring only on the peaks of Formon and Macaya at high elevations on the Massif de la Hotte.

Hispaniolan Crowned Frog. This species was named after a row of protuberances that resemble a crown on the back of its head. Prior to this expedition, the species was known from less than 10 individuals, and is likely to be extremely rare. It is an arboreal species, occurring in high-elevation cloud forest. Males call from bromeliads or orchids, which they seem to require for reproduction.

Macaya Burrowing Frog. Haiti is now the only place where two burrowing frogs are known to share the same habitat. This species has big jet black eyes and bright orange flashes on the legs. Males call from shallow, underground chambers and eggs are also laid underground, where they hatch directly into froglets.

Mysterious Animal Deaths of 2011

On New Year’s Eve, thousands of blackbirds plummeted to their death in a small town in Arkansas. Since then, several mysterious mass death of birds, fish, and crabs have been recorded worldwide. This string of animal die offs is being called Aflockalypse Now.

Here are a few of the mysterious mass die offs of animals that have occurred in that past two weeks:

FISH and CRABS

—40,000 Velvet swimming crabs, known as “devil crabs,” washed up along the Kent coast near Thanet, England.

—Two million small fish died in Chesapeake Bay, Maryland.

—Hundreds of snapper fish were found dead in Coromandel, New Zealand.

—100,000 dead or dying drum fish washed up along the Arkansas River.

—100 tons of fish washed up along the coast of Parangua, Brazil.

—Fish were also discovered rotting and floating in Port Orange, Florida.

BIRDS

—3,000 blackbirds fell on roofs and roads in the small town of Beebe, Arkansas.

—450 red-winged blackbirds, brown-headed cowbirds, grackles and starlings were found dead on a highway in Baton Rouge, Louisiana.

—Scores of American Coots were found dead on Texas highways.

—50 dead  jackdaws were found on a street in Falkoping, Sweden.

—1,000 turtle doves fell dead in Italy.

Why Did These Animals Die?

According to wildlife biologists, animal die offs are pretty common, but they are usually not reported or they occur under the radar. In fact, on average over 160 of these types of die offs occur each year in the United States alone. But because of the media focus on the macabre New Year’s Eve blackbird deaths in Arkansas, there was widespread awareness and reporting of other animal deaths around the world.

Here are a few of the reasons that might account for the animals’ deaths:

Weather: Cold and wet weather, as in Arkansas on New Year’s Eve, is often associated with mass bird deaths. Cold snaps may have also been responsible for most of the fish deaths, as well as the mass death of the devil crabs.

Parasites, pollution, or disease may be responsible. The animals are being tested, but results are not expected for several weeks.

Some have blamed the birds’ deaths on fireworks. This didn’t ring true to me—why don’t we see scores of birds dying after the Fourth of July? But perhaps the fireworks combined with unusually cold or wet weather caused the birds to become disoriented.

Migration and magnetism, My first thought when I heard about the animals’ deaths was that it might have something to do with magnetism. Some scientists believe that  movement of Magnetic North Pole, which is shifting an average of around 25 miles a year, may have caused some of the animal die offs. Birds and fish rely on it to migrate to breeding grounds and warmer climates. But the shifting pole could be confusing the animals — they may not migrate in time to avoid cold weather.

Renowned Harvard biologist E.O Wilson in a Christian Scientist Monitor article noted that that mass die offs — usually of animals with large populations — are getting all the attention while a larger but slower mass extinction of thousands of species* because of human activity is ignored.

The Canyon Tree Frog – Guest Post, Allystair D. Jones

We are extremely pleased to feature a guest post by Allystair D. Jones, who studied the canyon tree frog population in Zion National Park, Utah, to determine if the frogs were infected with the chytrid fungus, a disease that is wiping out amphibian populations worldwide. His research will be published by The Utah Academy of Science, Arts and Letters in May 2011. 

Chytridiomycosis is an emerging infectious disease that is plaguing the world and causing the extinction of frogs around the globe. This disease is believed to have come from Africa in 1938 when frogs were sometimes used to diagnose pregnancy. This disease is responsible for the extinction of at least 30 populations of frogs and has found its way into Arizona killing the canyon tree frog (Hyla arenicolor). The Chytrid disease can move very quickly and is transferred through water, contact, or even muddy boots from hikers. My research is aimed at watching the population of canyon tree frogs in Zion National Park and as of the summer of 2009 it appeared this population is safe.

The geography of Zion National Park is very unique. Zion is the middle step in the grand staircase with the Grand Canyon being the first and Bryce Canyon the last. This made locating the frogs often very difficult and technical rappelling and climbing skills were needed. I have been climbing for more than 20 years so I was especially suited for this study. I travelled through the canyons where this frog likes to live and captured, swabbed their bellies with a cotton swab, and released them back to the location that I caught them. I used the prescribed swabbing techniques and noted the location and time of the swab. I then saved the samples for DNA testing.

I tested all the samples with a general fungus primer, meaning I tested it to see if there was any fungus at all even if it wasn’t the chytrid fungus. Those that were positive for a fungus were tested for the specific chytrid. The results were very pleasing as none of the samples came up positive for this deadly fungus. This was the first study of this kind done in Zion National Park and during the following year there should be more if the funding keeps up.

It was noted in a review journal article at the beginning of this year (Kilpatrick et al 2010) that to help combat this disease we would need to find a viable population of frogs that are not already infected. I submit this population of frogs to be that population, that if monitored with care may help us gain ground in fighting this deadly disease. We need to increase our efforts to learn about this disease.
