27-06-2011 - Rancho Grande harlequin frog
Atelopus cruciger is a critically endangered frog believed to be extinct until recent sightings revealed populations at four sites. The presence of a fungus in the last specimens before the species disappeared in 1986 suggested a fungal disease as the most likely cause of its decline. This study aims to estimate demographic and epidemiological parameters in one of these populations to asses its viability.
