Rio Faisanes stubfoot toad
The Rio Faisanes stubfoot toad, ''Atelopus coynei'', is a species of toad in the Bufonidae family endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss.〔Ron, S., Coloma, L.A., Bustamante, M.R., Cisneros-Heredia, D., Almandáriz, A. & Yánez-Muñoz, M. 2004. (Atelopus coynei ). (2006 IUCN Red List of Threatened Species. ) Downloaded on 21 July 2007.〕
It was named after evolutionary biologist Jerry Coyne, who collected the holotype in a swamp on a frogging trip to western Ecuador as a student in the late 1970s.〔(''Atelopus coynei'', an eponymous frog ) (Jerry Coyne, ''Why Evolution Is True'', 2009-08-20)〕 It was thought to be extinct for many years, but was observed and photographed on February 7, 2012.〔(My frog is ALIVE! ) (Jerry Coyne, ''Why Evolution Is True'', 2012-02-16)〕
==Speciation==
The ancestral stock of the genus ''Atelopus'' was thought to be present in South America prior to the Tertiary era.〔C.Michael Hogan. 2013.(''Atelopus coynei'' ). eds. M.Koo & A.T.Chang. AmphibiaWeb. University of California, Berkeley〕 Species within the genus likely adapted to riparian habitats prior to the Andean uplift in the Cretaceous and Early Tertiary. As Andean uplift occurred, creating a more montane environment, it lifted the species and speciation resulted for the medium- to higher-altitude species members including ''A. coynei''; this higher-altitude adaptation likely reflected the ensuing vegetation and climate.
