Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
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
A. Limosus is threatened by chytridiomycosis and habitat loss. Species have been rapidly declining throughout their range. About 75% of all known species from highland sites above 1000 m have disappeared, while 58% of lowland species have declined and 38% have disappeared.
While the upland region seems to have been hard-hit by chytrid fungus, the fate of lowland populations of this species is uncertain, as chytridiomycosis appears to have more pronounced effects at upland sites.
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
