Geographic Range

This species is currently known only from the Cerro Sapo in south-western Darién Province, Panama. It is suspected that the species is more widely distributed, and may range through much of Parque Nacional Darién. It has been found at altitudes of 50-1,150m asl.

Comentarios

Is there any evidence to support Atelopus certus having a wider distribution?

Habitat

This is a terrestrial species of tropical montane and submontane forest. Breeding and larval development takes place in forest streams.

Does anybody have any recent information on the status of the population?

Threats

The main threats to the species are deforestation of habitat for agricultural use and general water pollution. Congeners are known to have virtually disappeared throughout much of Mesoamerica, probably due to chytridiomycosis, and this species might also be at risk from the disease, although it occurs at lower altitudes (the disease normally occurs at higher elevations in the tropics).

Comentarios

It has been noted that the population of Atelopus certus is stable (La Marca et al., 2003). However, the majority of Atelopus certus range is known to be habitable to chytrid fungus (Lotters et al., 2009).

Given the above information, I believe it may be warranted to change the following statement:

"...and this species might also be at risk from the disease, although it occurs at lower altitudes (the disease normally occurs at higher elevations in the tropics".

Clearly the habitat can host Bd, and as we know Atelopus sp. are extremely susceptible.

Does anybody have new information on Atelopus certus populations or know if Bd is in the area?

Specific Threats

  • 9.1.3 Type Unknown/Unrecorded
  • 2.1.1 Shifting agriculture
  • 2.1.2 Small-holder farming
  • 8.1.2 Named species
  • 9.3.4 Type Unknown/Unrecorded

Comentarios

Chytrid fungus should be listed as a threat, as it has been listed as part of the Red List Rationale (Below).

Conservation Actions

It has been recorded from Parque Nacional Darién. Further survey work is needed to establish the limits of the species' range, and additional research is needed to establish whether chytridiomycosis might be a threat.

Comentarios

A captive colony has been established at the Panamanian Amphibian Rescue and Conservation Project in Gamboa, Panama. The frogs have bred and raised successfully, and a founder population has been established.

Red List Rationale

Listed as Endangered because of a projected population decline, estimated to be more than 50% over the next ten years, inferred from declines in other high altitude Atelopus species in the same region, probably due to chytridiomycosis.

Comentarios

Atelopus certus is currently listed as Endangered, the rationale is listed above (population decline >50% over the next ten years inferred from declines in other Atelopus sp. due to chytridiomycosis). The previous assessment took place ten years ago (2004).

In order to upgrade the species to Critically Endangered (CR) a population decline of equal to or more than 80% in the next ten years. Does anybody have evidence of Bd in the area or population declines that would warrant the Critically Endangered (CR) listing?
