Range Description

Atelopus mittermeieri is known from the western slopes of the Cordillera Oriental, quebrada Aguas Claras (6 14' N, 72 56 W, 2525 masl) vereda Río Negro, Santuario de Flora y Fauna Guanentá-Alto Río Fonce, Municipality of El Encino, Department of Santander, Colombia (Acosta-Galvis et al. 2006).

Habitat and Ecology

The species inhabits montane humid forest with canopy heights not exceeding 10 m. This forest is rich in moss and lichens. Atelopus mittermeieri is a diurnal stream-associated species, where adults are found either near the margins of the Aguas Claras stream or in the stream itself. Tadpoles are also found within the stream. Breeding activity has been recorded for July, after the rainy season, although tadpoles have been found both during March and July. Calls attributed to this species have been heard during the months of May and August. One female revealed 393 cream-coloured eggs (Acosta-Galvis et al., 2006).

Population

The population at the type locality appears to be stable (Acosta-Galvis et al., 2006), although densities of adults are found to be low, while tadpole densities appear to be high (A. Acosta, pers. comm. 2008).

Population Trend

Decreasing

Major Threats

The presence of Batrachochytrium dendrobatidis has been confirmed for the known extant population of Atelopus mittermeieri (A. Acosta, pers. comm. 2008; Ruiz and Rueda-Almonacid, 2008), although live specimens did not exhibit clinical symptoms of chytridiomycosis (Ruiz and Rueda-Almonacid, 2008). Other possible threat factors include predation by introduced trout, pollution and sudden fluctuations in the stream's water level (Acosta-Galvis et al., 2006).

Conservation Actions

The species is being constantly monitored at the type locality, which is in a protected area. Efforts have been directed towards the captive breeding of this species, although unfortunately without positive results in producing captive-bred offspring.

Taxonomic Notes

Atelopus mittermeieri is distinguished from other species of the genus in the region by its colour patterns (Acosta-Galvis et al. 2006).
