Join us as together we Fight for Frogs

Brian swabs frogs in the field_Brian GratwickeFrogs matter. As a kid in nursery school, I remember observing tadpoles metamorphose into froglets right before our eyes in the classroom. It was like watching a magic trick over and over again. As I grew more interested in these cool little creatures, I learned that some frogs reproduce using pouches, others by swallowing their own eggs and regurgitating their young, others still by laying eggs that hatch directly into little froglets. It was like discovering not one magic trick, but an entire magical world—except this world was no illusion, it was real. My formative experiences both in the classroom and out rummaging around cold rainy ponds at night with my best friend and a headlamp spurred me into a career in the biological sciences. They also instilled in me a deep appreciation for the incredible diversity of life.

Panamanian golden frog_Brian GratwickeToday I am focused on conserving that incredible diversity specifically among amphibians in Panama, which is home to an astounding 214 amphibian species. Or at least it was. When a deadly amphibian chytrid fungus swept through, nine species disappeared entirely, including the country’s national animal, the beautiful Panamanian golden frog.

graphical abstractSince 2009, the Panama Amphibian Rescue and Conservation Project has spearheaded efforts to bring at-risk species into rescue pods to ride out the storm while we work on finding a cure. We’ve worked with partners to conduct several experiments in search of a cure and to better understand why some frogs resist infection and others do not. We have built new facilities that house highly endangered species of amphibians as part of a bigger global push to create an “Amphibian Ark.” These efforts and those of our colleagues around the world give me profound hope for our amphibian friends.

But we need your help.

Although frogs are the orchestral backdrop to every pond and forest, frogs have no voice to represent themselves, and they certainly can’t write checks. It’s up to professional conservationists, including the rescue project’s 12 talented conservationists in Panama, to save frogs so that others can enjoy them. This, however, requires money. From now until the end of August, our generous sponsor Golden Frog—a global online services provider with a terrific name—will match donations to the rescue project up to $20,000, helping us raise money critical to our fight for frogs. Your donations during the Fight for Frogs campaign will buy us equipment to care for the frogs in the rescue pods, help us continue to conduct experiments to find a cure, ensure crucial breakthroughs, and ultimately one day see the return of these incredible species to their home in the wild.

Together, let’s make a stand. Together, let’s #FightForFrogs.

The Panama Amphibian Rescue and Conservation Project is a project partnership between the Cheyenne Mountain Zoo, the Houston Zoo, Zoo New England and Smithsonian Institution.

Meet 9 of Panama’s ‘Lost Frogs’

The deadly amphibian chytrid fungus has caused much devastation to Panama’s native frogs, salamanders and caecilians. We have learned a lot about this disease in the last 10 years and we have been able to take stock of its effects. A recent survey of Panamanian frog experts revealed that of Panama’s 214 described amphibian species, about 100 species can still be reliably found even in places where the chytrid fungus is found, and experts consider these species less susceptible to the fungus. Approximately 80 species are very rare, and we simply do not have any idea about their susceptibility to chytridiomycosis, or their current population numbers. 36 species were considered highly susceptible to the chytrid fungus and were once reliably encountered but have experienced, or are predicted to experience, severe chytridiomycosis-related declines.
Unfortunately a number of these species have already completely disappeared in the wild and have not been seen in many years. We call these Panama’s ‘lost frogs’.

1) Atelopus chiriquiensis – Chiriquí harlequin frog
These attractive diurnal frogs were appealing research subjects and occurred in high numbers in highlands on the border of Costa Rica and Panama. There are many scientific papers about this species, and they were primarily studied for their highly toxic tetradotoxins in their skin as well as their unique signaling and aggressive mating behavior. A study by Dr. Karen Lips in the las Tablas reserve of Costa Rica reports that they occurred in high numbers – up to 20 individuals seen in 100m of stream on a single visit, but the frogs experienced a severe chytridiomycosis-related decline over a 5-year period and were last seen in 1996.

2) Atelopus zeteki – Panamanian golden frog
This is Panama’s national amphibian, a charismatic emblem of the environment and conservation. August 14th is a dedicated national day to honor the golden frog as a symbol for Panama’s incredible biodiversity heritage. Recognizing the chytridiomycosis threat, a conservation project called Project Golden Frog established a healthy breeding colony of golden frogs at the Maryland Zoo in Baltimore, another colony is maintained in Panama at the El Valle Amphibian Conservation Center. As predicted, Panamanian golden frogs experienced severe chytridiomycosis-related declines starting in 2006, and the last confirmed observation of Panamanian golden frog in the wild was in 2009. Project Atelopus continues to survey known golden frog sites for survivors, and a detailed conservation plan has been developed by stakeholders and facilitated by the IUCN Species Survival Commission for golden frogs in Panama. The plan aims to eventually reintroduce them to the wild.

3) Craugastor obesus
This species was found in the spray zone on rocks, boulders in the Atlantic-facing slopes of Western Panama and Costa Rica. The species was last recorded from Costa Rica in 1984 rainforest. This species belongs to the Craugastor rugulosus group and all these closely related species of amphibians have all been have been decimated by the amphibian chytrid fungus.
4) Craugastor punctariolus
This semi aquatic species was found in mountainous streams of Central Panama. Rapid chytridiomycosis-related declines and disappearances were observed in the field in 2004-2008. This species belongs to the Craugastor rugulosus group and all these closely related species of amphibians have been decimated by the amphibian chytrid fungus. Genetic analysis revealed that it is likely a species complex. It has been maintained in captivity, and occasionally deposited eggs that were either infertile or did not develop fully and a viable captive population was not established.

5) Craugastor rhyacobatrachus
This species is found in premontane and lower montane southern slopes of the Talamanca Mountains of Costa Rica and western Panama. Despite extensive searches for this species in both Costa Rica and Panama, there are no recent records of this species. This species belongs to the Craugastor rugulosus group and all these closely related species of amphibians have all been have been decimated by the amphibian chytrid fungus.
6) Incilius majordomus
Males of this species were lemon yellow, and females were brown, the only other known toad of this genus that exhibited similar sexual dimorphism was Incilius peringelis—the famous Monte Verde Golden Toad of Costa Rica that is now extinct. Incilius majordomus is known only from the Pacific slope of Cerro Bollo, on the border between the provinces of Bocas del Toro and Chiriquí. This species was described in 2013 using a series of specimens collected in 1980. It has not been seen in the wild since 1980 despite extensive herpetological surveys in the area.

7) Isthmohyla calypsa
A  treefrog frog covered with spiny tubercles found in a small mountainous area on the border of Costa Rica and Panama where is used to be locally common. At las Tablas in Costa Rica, the species experienced severe chytridiomycosis-related declines between 1993 and 1998. Despite extensive recent survey efforts in Costa Rica and Panama, the species has not been seen recently and is possibly extinct. Many other stream breeding species in this genus have also experienced dramatic declines and are now extremely rare frogs.

8) Ecnomiohyla rabborum – Rabbs’ fringe-limbed treefrog
Rabbs’ treefrog is thought to be endemic to the vicinity of El Valle de Anton, where it was always a rare frog difficult to find as they live high in trees and breed in tree holes. Experienced herpetologists could hear their calls reliably at some places, but the last individual was heard in El Valle de Anton in 2008. A few individuals of this species were collected for captive breeding efforts at the El Valle Amphibian Conservation Center and at the Atlanta Botanical Gardens, but captive breeding efforts were unsuccessful. As of 2015 only a single individual persists in captivity at the Atlanta Botanical Gardens.

9) Oophaga speciosa – Splendid poison frog
This large, unmistakable bright red dart frog lives only in the mountains of Western Panama. It was once collected for the pet trade, and was exported as recently as 1992. This species has not been seen in the wild in many years, despite intensive searches. It is not known whether it still lives in captivity, but has probably disappeared from the wild.

The Panama Amphibian Rescue and Conservation (PARC) project receives IX BBVA Foundation’s Biodiversity Conservation Award for Latin America

25 November, 2014, Madrid. The Panama Amphibian Rescue and Conservation (PARC) project was awarded the IX BBVA Foundation’s Biodiversity Conservation Award for Latin America, which recognizes projects, policies or actions that have had significant impact on the protection of habitats, species and ecosystems in Latin America.  Our project was chosen among approximately 30 nominations for its achievements in saving critically endangered amphibians in Panama and globally through research, rescue and outreach.

Roberto Ibanez BBVA Award

The award, made on Nov 25th at the Palacio del Marqués de Salamanca in Madrid, Spain includes a prize of 250,000 Euros (approx. $323,000).  The award was made to STRI’s Roberto Ibáñez, director of the Panama Amphibian Rescue and Conservation Project,  Heidi Ross, director and co-founder of the El Valle Amphibian Conservation Center, Sharon Ryan, STRI’s director of public programs and the Smithsonian Conservation Biology Institute’s Brian Gratwicke who is the international coordinator of the amphibian rescue project.

Panama Amphibian Rescue and Conservation Project LogoPARC was created in 2009 as a partnership of eight institutions, in response to the massive loss of Panama’s amphibian biodiversity due mainly to the chytrid fungus, and has several key goals: prevent species extinctions by establishing ex-situ assurance colonies of endangered amphibians threatened with extinction from a deadly fungus decimating amphibians worldwide; develop tools to mitigate the disease and lead to reintroductions in the wild; and, engage constituents to support conservation of amphibians and habitats.

The founding organizations include Africam Safari, Houston Zoo, Cheyenne Mountain Zoo, New England Zoo, Smithsonian Conservation Biology Institute, Defenders of Wildlife and  the Smithsonian Tropical Research Institute.

To date, we have invested $1.5 million to build two ex-situ facilities in Panama, bred more than 10 endangered amphibian species, including the Panamanian Golden Frog, a conservation flagship species now extinct in the wild. Our scientists actively monitor disease and frog populations in the wild, use the latest molecular tools to find beneficial skin bacteria to help frogs fight chytridiomycosis infections, research genetic mechanisms of chytrid resistance in Panamanian Golden Frogs, and develop assisted reproduction technologies to breed frogs in captivity and cryopreserve their gametes for future use.

The Panama Amphibian Rescue and Conservation Project’s education campaign generates extensive coverage in local and international press, raising awareness and support for this crisis, including: award-winning documentary aired on Smithsonian Channel in the USA, and coverage in major media outlets. Our annual Panamanian Golden Frog Festival drew 6,280 people in 2013 and had a media reach of nearly 500,000. Two exhibits, the Fabulous Frogs of Panama in Panama City and another at the El Valle Amphibian Conservation Center are visited by 200,000 Panamanians annually. More than 35,000 schoolchildren and 300 teachers participate annually in amphibian-related education programs.  Nearly 300 volunteers have supported the project since 2009.

The Recently Discovered Salamander-Devouring Fungus and Reasons for Concern for the Future the Salamander Biodiversity in the United States

appalachian salamandersEnigmatic Fire salamander (Salamandra salamandra) declines in the Netherlands have been attributed to the recently described fungal pathogen Batrachochytrium salamandrivorans (Bs). Since 2010, the S. salamandra population at Bunderbos, Netherlands has decreased by 96%. An Martel et al’s recent Science paper showed that some US salamander species are highly susceptible to Bs, confirmed its occurrence in the pet trade, and noted that it has not yet been detected in the US. Large numbers of live salamanders are legally imported into the US each year for the pet trade. In the first 6 months of 2014, for example, 3,445 fire salamanders imported into the US, mostly from Slovenia.

The genus Batrachochytrium, which before the discovery of Bs solely included Batrachochytrium dendrobatidis (Bd), has gained an infamous reputation for global amphibian declines. Biologists believe that we are witnessing the sixth mass extinction in part because of the virulence and global spread of Bd among the world’s amphibians. The discovery of this new pathogen and our improved understanding of the ravaging effects of emerging wildlife disease raise concerns that US salamanders could share the same fate.

The US is a biodiversity hotspot for salamanders

The Appalachian Mountains are a renowned biodiversity hotspot for salamanders. The potential threat of this emerging pathogen in the US is therefore magnified, and it is imperative that we keep this disease out of the US. Salamander genetic diversity in the Appalachians is the highest in the world with 72 salamander species that are mostly endemic. The United States is home to nine out of ten salamander families and four of the ten extant salamander families are endemic to the United States including amphiumas, Pacific giant salamanders, torrent salamanders and sirens. Mole salamanders are also found in Canada and Mexico, but nearly all of their biodiversity is contained with U.S. borders. Giant salamanders are a primitive lineage of giant salamanders with three extant species, located in the U.S., Japan, and China. The hellbender is one of the giants and has found refuge in the Appalachian Mountains since amphibians originated, some 360 million years ago.

The ecological role of salamanders, the smaller majority, can often go unnoticed, but consider this biomass assessment of salamanders in Appalachia. One classic mark-recapture study in the eastern US noted “The biomass of salamanders is about twice that of birds during the bird’s peak breeding season and is about equal to the biomass of small mammals” (Burton and Likens 1975). With densities this high, a novel salamander-specific pathogen to which these animals have never been exposed have the potential be able to spread like wildfire, much like Bd spread through naïve Neotropical amphibian populations.

Immediate action is needed

We should immediately halt the importation of salamanders from any overseas sources, unless they can be certified free from Bs and Bd. In May 2008 the OIE, which is the organization created to mitigate zoonotic diseases (i.e., anthrax, mad cow disease, etc.), recognized Bd as a notifiable disease. Stricter trade regulations recommended by OIE would substantially reduce the spread of both Bs and Bd, however the OIE changes have not been adopted by the US Department of Agriculture and Interior and until doing so there are no legal means to reject infected shipments. A joint statement from the Amphibian Specialist Group and Amphibian Survival Alliance calls for immediate policy actions to stop the further spread of devastating wildlife diseases, and this time it is not too late to do something about it.

Scientists discover new poison dart frog species in Donoso, Panama

Andinobates geminisae

A bright orange poison dart frog with a unique call was discovered in Donoso, Panama, and described by researchers from the Smithsonian Tropical Research Institute and the Universidad Autónoma de Chiriquí in Panama, and the Universidad de los Andes in Colombia. In the species description published this week in Zootaxa, it was named Andinobates geminisae for Geminis Vargas, “the beloved wife of [coauthor] Marcos Ponce, for her unconditional support of his studies of Panamanian herpetology.”

Every new species name is based on a representative specimen. The specimen for this species was collected Feb. 21, 2011, in the headwaters of the Rio Caño, in the district of Donoso, Colón Province, Panama, by Samuel Valdés, who was then the MWH Global Inc. environment office director, and his field assistant, Carlos de la Cruz. Additional specimens were collected between the Rio Coclé del Norte and the Rio Belen by biologists Marcos Ponce and Abel Batista, then a student at the Universidad Autónoma de Chiriquí. The specimens were deposited in the Museo de Vertebrados at the University of Panama, the Museo Herpetólogico de Chiriquí at the Universidad Autónoma de Chiriquí and in the Círculo Herpetólogico de Panamá.

“Abel Batista and Marcos Ponce were the first to note the presence of this species,” said Cesar Jaramillo, Smithsonian herpetologist. “They’ve known it was there for several years. However, they were not sure if it was only a variety of another poison dart frog species, Oophaga pumilio, which exhibits tremendous color variation. Based on morphological characteristics of the adult and the tadpole, I thought it might be a new species of Andinobates.”

Andrew Crawford, professor at Universidad de Los Andes and former STRI postdoctoral fellow, sequenced the DNA, confirming that this was a new species of Andinobates. Genetic information about this species is available in the Barcode of Life Data System and in GenBank. A recording of the call is available at AmphibiaWeb.org.

Because this new frog species appears to be found in only a very small area, habitat loss and collecting for the pet trade are major threats to its existence. The authors recommend the formulation of special conservation plans to guarantee its survival. A. geminisae is included in the captive breeding program of the Panama Amphibian Rescue and Conservation project, a consortium of six zoos and research institutions dedicated to saving amphibians from the chytrid fungal disease, which is decimating amphibians worldwide, and habitat loss.

Ecuador Cochran frog (Nymphargus griffithi)

Ecuador cochran frog (Nymphargus griffithi)

Cute Frog of the Week: March 25, 2013

The Ecuador cochran frog is a brightly colored frog found most often on vegetation next to streams in montane forests. Although its name points to Ecuador, it appears to have disappeared from its original region and is now found most commonly in Columbia. The Cochran frog population is currently in a decline due to habitat loss from deforestation for agricultural development, logging and human settlement. The introduction of alien predatory fish to the area and pollution resulting from the spraying of illegal crops has also had a negative effect on the species. Due to these factors, the IUCN has listed them as vulnerable on the IUCN Red List.

Rescue Project Successfully Breeds Endangered Frog Species

The limosa harlequin frog (Atelopus limosus), an endangered species native to Panama, now has a new lease on life. The Panama Amphibian Rescue and Conservation Project is successfully breeding the chevron-patterned form of the species in captivity for the first time. The rescue project is raising nine healthy frogs from one mating pair and hundreds of tadpoles from another pair.

“These frogs represent the last hope for their species,” said Brian Gratwicke, international coordinator for the project and a research biologist at the Smithsonian Conservation Biology Institute, one of six project partners. “This new generation is hugely inspiring to us as we work to conserve and care for this species and others.”

Nearly one-third of the world’s amphibian species are at risk of extinction. The rescue project aims to save priority species of frogs in Panama, one of the world’s last strongholds for amphibian biodiversity. While the global amphibian crisis is the result of habitat loss, climate change and pollution, a fungal disease, chytridiomycosis, is likely responsible for as many as 94 of 120 frog species disappearing since 1980.

Between its facilities at the Smithsonian Tropical Research Institute in Gamboa, Panama, and the El Valle Amphibian Conservation Center in El Valle, Panama, the rescue project currently cares for 55 adult limosa harlequin frogs of the chevron-patterned form and 10 of the plain-color form. The project has had limited success breeding the plain-color form of this species, and has successfully bred other challenging endangered species, including crowned treefrogs (Anotheca spinosa), horned marsupial frogs (Gastrotheca cornuta) and toad mountain harlequin frogs (A. certus).

Each species requires its own unique husbandry to thrive and breed. The project’s animal care team and scientists learn husbandry techniques as they work with a limited number of individuals. Jorge Guerrel, conservation biologist at the Smithsonian Tropical Research Institute, arranged rocks in the breeding tank to create the submerged caves that appear to be the preferred egg deposition sites for limosa harlequin frogs. Like other Atelopus species, tadpoles require highly oxygenated, gently flowing water between 22 and 24 degrees Celsius. The tadpoles’ natural food is algal film growing on submerged rocks, which Guerrel and his colleagues re-created by painting petri dishes with a solution of powdered spirulina algae, then allowing it to dry.

The mission of the Panama Amphibian Rescue and Conservation Project is to rescue amphibian species that are in extreme danger of extinction throughout Panama. The project’s efforts and expertise are focused on establishing assurance colonies and developing methodologies to reduce the impact of the amphibian chytrid fungus so that one day captive amphibians may be reintroduced to the wild. Current project partners include Cheyenne Mountain Zoo, Houston Zoo, Smithsonian’s National Zoological Park, Smithsonian Tropical Research Institute and Zoo New England.

Turquino Robber Frog (Eleutherodactylus turquinensis )

Turquino robber frog (Eleutherodactylus turquinensis )

Cute Frog of the Week: March 4, 2013

The turquino robber frog is a small frog, but large for Eleutherodactylids. It is a semi-aquatic frog found in small mountain streams in cloud forest and fragmented areas at high altitudes. Endemic to Cuba, this frog is known only from the Sierra del Turquino (Sierra Maestra Mountains) in eastern Cuba. These little robbers can be found on stream banks clinging to wet rocks in the splash zone, prepared to dive underwater for a quick getaway if needed. Due to habitat loss and their limited area of occupancy, this species is classified as critically endangered by the IUCN.

Marañón poison frog (Excidobates mysteriosus)

Marañón poison frog (Excidobates mysteriosus)

Cute Frog of the Week: February 25, 2013

This little polka-dotted guy is actually one of the most distinctive poisonous frogs. Adults are black or brown, sporting fashionable white “polka-dots” that cover their entire body. This spotting is highly variable from frog to frog, with the exception of a single spot under the chin and an oval spot on the underside of the thighs. The species is known from a single location in the vicinity of Santa Rosa, Cajamarca, Peru and often lives in giant bromeliad flowers. Unfortunately, because of land destruction for coffee farms in the area around Santa Rosa, this species is losing its habitat and becoming severely threatened in the wild. Humans have also begun to want these beautiful amphibians as terrarium pets. These threats have caused the IUCN to classify the spotted frog as endangered by the IUCN.
