I’ve got a resume that’ll make you jealous.

Pepper tree frog (Trachycephalus venulosus)

Pepper tree frog (Trachycephalus venulosus)

Cute Frog of the Week: July 25, 2011

Unlike many specialized species that inhabit Panama, the pepper tree frog can live just about anywhere (and does) and expands the boundary of frog behavior. Listed all together, its attributes make for a compelling resume. If we start reading at the top of the list, we find out that it lives from Argentina’s savannahs to Mexico’s forest fragments, from Brazil’s Amazon rain forest to Colombia’s dry forest, and almost everywhere in between. It is as comfortable in the low coastal canopies as it is in tall trees 1.6 kilometers above sea level. Further down its resume, we come to learn about its swimming trick, in which it uses inflatable vocal sacks to float in shallow pools while calling for a mate. And a bit more impressive: it is a skilled parachutist, capable of gliding, not strictly falling, from canopy branches to the forest floor. The tadpole’s large gills and lungs are the evolutionary result of adapting to oxygen-depleted and warm small pools of water. Last but not least, we get to the trademark attribute. Its skin glands secrete sticky, noxious, and water-insoluble mucus at potential predators. Herpetologists (who wrote the list) have witnessed snakes recoiling from the stuff. In addition, its insolubility helps the frog’s porous skin remain moist during the dry season. Having reached the bottom of the long list, we come to realize just how deep and varied its resume is for a tree frog. Maybe adaptability explains its healthy global population. But why the “pepper” tree frog? The answer: its irritating mucus allegedly makes you sneeze as pepper does (according to reports in Belize).

Mamoni Valley: A Rescue Mission

It isn’t every day that one gets to travel to the heart of one of Panama’s richest rain forests on a rescue mission to save some of Panama’s most endangered amphibians. A brief two-hour drive from Panama City brought us to a facility run by Earth Train called the Mamoni Valley. I was lucky enough to be able to shadow leading herpetologists, Brian Gratwicke and Roberto Ibáñez, on one of their field expeditions to rescue endangered frogs.

One of the main objectives for our expedition to Mamoni Valley was to rescue a rapidly declining harlequin frog called Atelopus limosus and to launch the Global Amphibian Bioblitz, a citizen-science initiative to document as many amphibian species on the planet as possible. Hours of sweaty hiking up and down a mountain track in the dark brought us to a cool, clear stream where we began our search for frogs. After studying each passing leaf fruitlessly, and slipping and falling in the stream a few times, I found myself impressed at how much skill and patience it actually takes to capture frogs. But the numerous hours of careful searching in the streams both day and night turned out to be well worth the effort because we found some beautiful Atelopus limosus along with 13 other species of glass frogs, poison dart frogs, toads, rocket frogs and some spectacular snakes. We bagged each frog we collected and swabbed them individually. Each swab will be tested for the deadly amphibian chytrid fungus back at the Smithsonian Tropical Research Institute lab.

Each day when we returned from our 5-6 hour expeditions, there was always a feeling of success in the air, because we did find few Atelopus limosus, but it was always slightly reserved. Although I thought the number of frogs we had collected was fantastic, I learned quickly that the team had encountered many more frogs on previous visits to the site. It was extremely sobering for me to look at the worried faces of the experts sitting next to me as they explained that at current rates of decline it would be unlikely that we would find any more Atelopus limosus next year, and that I was in a very privileged position of being able to see a rapidly declining species in the wild, because few people will ever have that opportunity again.

This Amphibian Rescue Mission to Mamoni Valley not only taught me a great deal about the grave dangers that many amphibians face, but it also gave new perspective on how important it is to save these beautiful, endangered frogs before it’s too late. If you would like to help the global amphibian effort – try to mount your own amphibian expedition to a nearby park or pond and then share your photos on the Global Amphibian Blitz website!

Stirred, not shaken…

Olive striped frog (Phlyctimantis leonardi)

Olive striped frog (Phlyctimantis leonardi)

Cute Frog of the Week: July 18, 2011

Though what is visible here isn’t reminiscent of the popular martini garnish, this does not mean the olive striped frog isn’t incredibly stylish and suave in its own right. This frog is native to the Congo, Gabon and Equatorial Guinea. Males range from 45 to 59 millimeters long, but while this frog isn’t the most physically intimidating contender in the amphibian ring, its call makes up for its somewhat diminutive size. Researchers have observed male olive striped frogs calling from bushes approximately 1 to 2.5 meters above the flooded grasslands where these frogs mate. Scientists believe they live in secondary forests and heavily degraded former forests, moving to more open areas like the grasslands to attract potential mates with greater visibility and volume.  According to the International Union for Conservation of Nature, the olive striped frog is a species of least concern, meaning that while these frogs might be geographically constricted, they currently have few other threats shaking up their status.

The Hidden Jewels of Appalachia

 

“The Hidden Jewels of Appalachia” is a short film that uses compelling imagery to showcase Appalachia and raise awareness for declining Appalachian salamanders.  The Appalachian region of the eastern United States features an ancient mountain chain that serves as the world’s epicenter for salamander biodiversity.  These secretive creatures, ranging in size from two inches to more than two feet, are a keystone species at risk from a perfect storm of threats, including: development, climate change, mountaintop mining, invasive species, disease, transportation corridors, acid rain, pollution, and more.  Learn what these declining “canaries in the coal mine” are telling us about the state of our environment.

The Smithsonian Conservation Biology Institute is working to become a leader in salamander conservation through innovative research looking at Plethodon species competition and climate change affecting the eastern hellbender (Cryptobranchus alleganiesis), as well as working to connect people to their local environment through public presentations, conducting field surveys and swabbing salamanders for disease.  For more information, please find Appalachian salamanders on Facebook.

Bright-eyed frog (Boophis calcaratus)

Bright-eyed frog (Boophis calcaratus)

Cute Frog of the Week: July 11, 2011

The quiet that falls over forests in eastern Madagascar with the arrival of night is interrupted by the bright-eyed frog (Boophis calcaratus). This tiny nocturnal frog sounds its calls from its perch in the branches on the outskirts of forests and degraded rainforests. Not all of their time is spent hanging around in the trees, however. They can also be found on the ground, usually near pools of freshwater.

Since this frog is most active from sunset to sunrise, it can be difficult to see with its brown spots and banding. A little light would illuminate how the frog got its name: its eyes. Its large pupils are surrounded by vivid irises. Scientists are not sure why the frogs have such colorful blue-green irises, but they do know that frog species within the Boophis genus can be identified by their eye color, in addition to their calls.

Zoo Collegiate Conservation Program aims to save endangered amphibians

Houston toad (Bufo houstonensis)

College interns at the Houston Zoo participating in this summer’s Collegiate Conservation Program worked with Zoo conservation staff to build breeding habitats on Zoo grounds with the goal of increasing the population of Houston toads (photo courtesy of the Houston Zoo).

The next generation of wildlife biologists gathered at the Houston Zoo recently to save an endangered species–the Houston toad.

College interns at the Houston Zoo participating in this summer’s Collegiate Conservation Program worked with Zoo conservation staff to build breeding habitats on Zoo grounds with the goal of increasing the population of the endangered amphibians.

In the spring of 2007, parts of the only known egg strands laid by Houston toads that year were collected for a head start by biologists at Texas State University and delivered to the Houston Zoo.

The eggs came to the zoo for several purposes. The first is as a safe guard, or “assurance population,” against a catastrophic event that might cause the Houston Toad to go extinct in the wild.

The second reason was for the potential reintroduction of toads into appropriate habitat. It is hoped the captive toads will serve as a source for individuals who might be reintroduced into historical localities. The third reason is for head starting.

The eggs hatched and about 1,500 toads completed metamorphosis. We performed three releases in 2007 (May, July and September) and another in April 2008. About 1,200 toads were released in total. The remaining toads were kept at the zoo to start the formation of our assurance colony.

Since 2007 we have head started and released about another 20,000 toads at sites in two counties within the toads’ range.

Now the effort is expanding, and with the help of interns from the Collegiate Conservation Program, the Zoo’s conservation department is moving to the next step–breeding Houston toads ‘the old fashioned way’ (that is, without the use of hormones) in habitats on Zoo grounds.

Recently the interns began the construction of a facility in a shaded off-exhibit area at the Zoo that mimics the toad’s natural habitat: sandy soil that allows the toads to burrow until they are ready to emerge for breeding season.

Established this year with a $50,000 contribution by the ExxonMobil Foundation, the Houston Zoo Collegiate Conservation Program is the only zoo conservation internship program of its kind in the nation.

University students working toward degrees in biology, zoology and environmental science are paid over the summer to study various animals in natural habitats as part of the Zoo internship. In addition to working with Houston toads, the interns are assisting with native Texas coastal prairie restoration and an environmental restoration project in the Big Thicket National Preserve.

The great awakening.

Appenine yellow-bellied toad (Bombina pachypus)

Apennine yellow-bellied toad (Bombina pachypus)

Cute Frog of the Week: July 4, 2011

From the southernmost tip of the Italian peninsula to the Apennine region, just south of the Po River Valley, spring signals the awakening of the Apennine yellow-bellied toad (Bambina pachypus) from its long hibernation. This brown spotted toad, with a brightly colored underbelly, wastes no time after coming out of its deep sleep and begins breeding. From May to September the toad will breed multiple times and females will lay clutches of a few eggs to a few dozen eggs in temporary pools of freshwater. Males are ever-ready for the marathon breeding season. They use sperm their bodies produced for the previous breeding season to fertilize eggs early in the breeding season, while new sperm develops to use for later on in the current season. The Apennine yellow-bellied toad will go through this process many times as it can live for up to 16 years in the wild. The average lifespan for the toad is generally half that. It does not reach sexual maturity until it is three years.

The toad’s odd coloring on its underbelly—black and white with large spots of yellow—serves a very distinct purpose. It is a warning to predators that the Apennine yellow-bellied toad is poisonous and not to be messed with.  It secretes a toxic substance when it is threatened. The substance is not all bad; it is also antimicrobial and antifungal.
