Description

provided by AmphibiaWeb articles
Adult males reach up to 36 mm and adult females reach at least 48 mm in snout-vent length. The ground color is uniform brown, or lighter brown with small yellowish white blotches that may have brown centers or a line through them. The venter is yellow (Savage 1972).The genus Atelopus appears to be the most threatened clade of amphibians (La Marca et al. 2005). 60 of the 85 described Atelopus species are classified as Critically Endangered by the IUCN. At least 30 species appear to be extinct, having been missing from all known localities for at least 8 years (La Marca et al. 2005). Of the surviving species with sufficient data to evaluate population trends, the majority (42 of 52 species, or 81%) have population sizes that have been reduced by at least half (La Marca et al. 2005). Higher-elevation species (those living at least 1000 m asl) have been hit the worst, with 75% (21 of 28) having disappeared entirely (La Marca et al. 2005). Chytridiomycosis is thought to be a primary factor in the decline and disappearance of species in this genus (La Marca et al. 2005). Most Atelopus species are restricted to very limited areas (no more than two localities) and occur along mid- to high-elevation streams at 1500-3000 m asl (Lötters 2007). This habitat preference is frequently associated with the co-occurrence of chytridiomycosis (La Marca et al. 2005). Although habitat loss has occurred within the ranges of many Atelopus species, it does not appear to be a major factor in the declines of most Atelopus species; 22 species declined despite occurring in protected areas (La Marca et al. 2005). Many Atelopus species are local endemics, putting them at particular risk of extinction, with at least 26 species known only from a single population inhabiting a narrow altitudinal range (La Marca et al. 2005). Due to their restricted ranges, they are also thought to have limited ability to adapt to warming climatic conditions (Lötters 2007).Atelopus glyphus was first described by Dunn (1931), as Atelopus varius glyphus.

Life History, Abundance, Activity, and Special Behaviors

The biggest threat is chytridiomycosis, which is predicted to arrive at the species locality within five years as the chytrid fungus proceeds through Panama (Ibañez et al. 2004). Chytrid has devastated many other species of Atelopus, particularly those associated with montane streams (La Marca et al. 2005). Habitat loss may also be an issue; it is not known whether this species can survive in disturbed forest. Atelopus glyphus occurs in two protected areas, one in Panama (Parque Nacional Darién, a World Heritage Site) and one in Colombia (Parque Nacional Natural los Katíos) (Ibañez et al. 2004). Although this ensures that some suitable habitat is present, it does not in any way ensure protection from chytrid fungus, which has decimated many species in pristine areas (La Marca et al. 2005).

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
This species is terrestrial. It breeds in forest streams (Ibañez et al. 2004). Although the breeding biology of Atelopus glyphus has not yet been described, other species of Atelopus are known to attach their eggs to the undersides of rocks in swift-moving streams, during the dry season when water is relatively low (Savage 1972). Atelopus eggs are laid in strings (Starrett 1967). Larvae develop as the wet season begins and water flow increases (Savage 1972). All Atelopus tadpoles have large ventral suckers, distinct from the mouth, allowing the tadpoles to cling to stream rocks even in torrents (Starrett 1967).

Relation to Humans

provided by AmphibiaWeb articles
Amphibian Ark has chosen Atelopus glyphus for the first ever Facebook fundraiser (http://apps.facebook.com/causes/cause_goals/11040?m=14f7a052) to save an endangered species. The goal is to raise $53,000 by June 2, 2009, for a species-specific rescue facility and costs associated with the first year of operation. The "amphibian pod" rescue facility will be based at the Summit Zoo in Panama City, Panama. It will begin with about 20 wild-caught breeding pairs, eventually reaching up to 500 frogs including captive-bred offspring. Initial breeding efforts at the El Valle del Anton Amphibian Conservation Center in Panama were successful, indicating this species is a good candidate for captive management until wild populations can be re-established. The rescue facility itself consists of a 40' shipping container, modified to include shelves, tanks, plumbing, an electrical system, HVAC (heating, ventilation and air conditioning), a water heater, and a repressurization pump and water storage container, as well as a large window for public viewing. The container itself, plus modification, plus shipping to Panama and hooking up to utility lines, costs a total of approximately $41,000. The first year of operating costs will be $12,000.The concept of using a modified shipping container as an "amphibian pod" rescue facility was pioneered in Australia. The Summit Zoo hopes eventually to use a number of these "amphibian pods" to house more colonies of endangered amphibians from the central region of Panama, where chytrid has had a severe impact.

Atelopus glyphus

provided by wikipedia EN

Atelopus glyphus, the Pirri harlequin frog[1][2] or Pirri Range stubfoot toad, is a species of toad in the family Bufonidae found in Colombia and Panama within the Northwestern Andean montane forests.[3] Its natural habitats are subtropical or tropical moist montane forests and rivers.[1]

Morphology and behaviour

This species is terrestrial, and breeds in forest streams. The reproductive biology is not well-known, but other Atelopus species are known to attach their eggs to the undersides of rocks in swift-moving streams during dry seasons when the water level is low. The eggs are laid in strings, and the larvae develop as the wet season begins. All Atelopus tadpoles have large ventral suckers, allowing them to hang on to rocks even in torrents.

Conservation

The biggest threat to this and other, similar species is chytridiomycosis. The disease has affected many other species of Atelopus, particularly those associated with montane streams. This toad lives in two protected areas in Panama and Colombia. This guarantees some suitable habitat, but does not protect it from the chytrid fungus.

Tadpole

It is also threatened by habitat loss, urbanization, climate change, pesticides, and intensified agriculture, including grazing. Atelopus happens to be the most threatened clade of amphibians, where 60 of the 85 described species are classified as critically endangered by the IUCN. In addition, at least 30 known species are extinct. Of the surviving species, and those on which enough data exist to evaluate population trends, 81% have population sizes reduced by at least half from historical levels. The higher-elevation species, those living at or above 1,000 metres (3,300 ft), have been hit the worst, with 75% having disappeared entirely.[2]

Herpetologie

Atelopus glyphus is een kikker uit de familie padden (Bufonidae) en het geslacht klompvoetkikkers (Atelopus). De soort werd voor het eerst wetenschappelijk beschreven door Emmett Reid Dunn in 1931.[2]

Atelopus glyphus leeft in delen van Zuid-Amerika en komt voor in de landen Colombia en Panama. De kikker is bekend van een hoogte van 1200 tot 1445 meter boven zeeniveau. De soort komt in een relatief klein gebied voor en is hierdoor kwetsbaar. Door de internationale natuurbeschermingsorganisatie IUCN wordt de soort beschouwd als 'kritiek'.[3]

Atelopus glyphus heeft een bruine lichaamskleur en een gele buik. Mannetjes worden ongeveer 36 millimeter lang, de vrouwtjes worden groter en bereiken een lichaamslengte van ten minste 48 mm.[4]
