Breeding

Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.

Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.

In crisis

The biggest threat to this and other, similar species is chytridiomycosis. It is also threatened by habitat loss, urbanization, climate change, pesticides, and intensified agriculture, among them 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 that enough data exist to evaluate population trends, 81% have population sizes reduced by at least half from historical levels.

Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.

Atelopus glyphus is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
