Contents

Colostethus panamansis, also known as the Panama rocket frog [1] or (ambiguously) common rocket frog, [3] is a species of poison dart frog. It is found in northwestern Colombia and Panama. [2] [4] It is one of the best studied poison dart frogs; however, until 2004 Colostethus panamansis was considered a synonym of Colostethus inguinalis , and consequently the older literature uses that name. [5]

Distribution and habitat

Female carrying tadpoles on her back

Colostethus panamansis is found in several parts of Panama and in Parque Nacional Natural Los Katios in Colombia. It is found living near streams in forested lowland and hilly country, usually at elevations below 800 metres (2,600 ft). [1]

Biology

Adult males measure 19–27 mm (0.75–1.06 in) in snout–vent length and adult females 25–29 mm (0.98–1.14 in). [5]

The female lays her eggs in clutches among leaf litter. When they hatch, she carries them around on her back for up to nine days when she immerses herself in a fast flowing stream and they become detached and continue their development in the water. [3]

Research

The pathogenic fungus Batrachochytrium dendrobatidis causes the emerging infectious disease chytridiomycosis which is the cause of the decline in many species of tropical amphibian. Colostethus panamansis was used to demonstrate that the fungus was indeed the pathogen responsible for the disease. Healthy rocket frogs from El Copé in Panama were collected and shown to be free of B. dendrobatidis. They were then exposed to an isolate of the fungus. Some of these died and from these B. dendrobatidis was reisolated and was demonstrated to be identical to the original infective agent thus fulfilling Koch's postulates. [6]

Conservation status

Colostethus panamansis is listed as being of "Least Concern" in the IUCN Red List of Threatened Species. This is because it has a wide range in which it is common, and though the population may be declining, this is not at a rate to allow it to qualify for a higher category. The chief threats it faces are deforestation, logging and farming activities including pollution of streams with pesticides. [1]

Poison dart frog Family of amphibians

Poison dart frog is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this from their diet of ants, mites and termites. Other species however, that exhibit cryptic coloration and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching on their habitats.

Chytridiomycosis

Chytridiomycosis(chy·​trid·​i·​o·​my·​co·​sis | \ kī-ˌtri-dē-ō-mī-ˈkō-səs) is an infectious disease in amphibians, caused by the chytrid fungi Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans, a non-hyphal zoosporic fungus. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, East Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian populations that apparently has affected about 30% of the amphibian species of the world. Some research found evidence insufficient for linking chytrid fungi and chytridiomycosis to global amphibian declines, but more recent research establishes a connection and attributes the spread of the disease to its transmission through international trade routes into native ecosystems.

Colostethus is a genus of poison dart frogs native to Central and South America, from Panama south to Colombia, Ecuador, and northern Peru. Their common name is rocket frogs, but this name may refer to frogs in other genera and families, following the taxonomic revision of the genus in 2006.

<i>Batrachochytrium dendrobatidis</i> Species of fungus

Batrachochytrium dendrobatidis, also known as Bd or the amphibian chytrid fungus, is a fungus that causes the disease chytridiomycosis in amphibians.

Panamanian golden frog Species of amphibian

The Panamanian golden frog, also known as Cerro Campana stubfoot toad and other names, is a species of toad endemic to Panama. Panamanian golden frogs inhabit the streams along the mountainous slopes of the Cordilleran cloud forests of west-central Panama. While the IUCN lists it as critically endangered, it may in fact have been extinct in the wild since 2007. Individuals have been collected for breeding in captivity in a bid to preserve the species. The alternative common name, Zetek's golden frog, and the epithet zeteki both commemorate the entomologist James Zetek.

<i>Atelopus varius</i> Species of amphibian

Atelopus varius, the Costa Rican variable harlequin toad or clown frog, is a small Neotropical true toad from the family Bufonidae. Once ranging from Costa Rica to Panama, A. varius is now listed as critically endangered and has been reduced to a single remnant population near Quepos, Costa Rica and has only relict populations in western Panama (IUCN). Recent variation in air temperature, precipitation, stream flow patterns, and the subsequent spread of a pathogenic chytrid fungus (Batrachochytrium dendrobatidis) linked to global climate change have been the leading cause of decline for A. varius. A. zeteki has been considered a subspecies of A. varius, but is now generally considered a separate species.

<i>Espadarana prosoblepon</i> Species of amphibian

Centrolene prosoblepon is a species of frog in the family Centrolenidae, commonly known as the emerald glass frog or Nicaragua giant glass frog.

It is a nocturnal species occurring in low vegetation in mature forests only. It is not considered threatened overall by the IUCN although deforestation and pollution are potential threats, as is chytridiomycosis.
