Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-11-07
Assessor(s): Diego F. Cisneros-Heredia
Reviewer(s): Ariadne Angulo and Simon Stuart
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on the Amazonian slopes of the Ecuadorian Andes.
Previously published Red List assessments:
2008 Vulnerable (VU)

Geographic Range [top]

Range Description: Centrolene mariaelenae is known from seven localities along the slopes of Cordillera Oriental, provinces of Napo, Orellana, Morona-Santiago and Zamora-Chinchipe, Ecuador (Cisneros-Heredia and McDiarmid, 2006, 2007; Cisneros-Heredia and Guayasamin, 2006). The species can be found between 1400 and 1820 masl (Cisneros-Heredia and McDiarmid, 2007).

Population [top]

Population: The species is rare at all known localities, where usually just one or two specimens have been collected despite significant collection efforts (D.F. Cisneros-Heredia, pers. comm. 2008).
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: All individuals with natural history information were active at night, on leaves up to 5 m above water of small streams in primary or old secondary-growth Low Montane Evergreen Forest. Other centrolenid frogs in sympatry with this species
are Cochranella cochranae and an undescribed species of Centrolene (Cisneros-Heredia and McDiarmid, 2006). The species may use temporary (seasonal) sources of running water during the reproductive period. During the non-reproductive period the species appears to inhabit the forest canopy (D.F. Cisneros-Heredia, pers. comm. 2008).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat destruction (deforestation) and water pollution (D.F. Cisneros-Heredia, pers. comm. 2008). Predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions [top]

Conservation Actions: This species is found within Podocarpus National Park and Cayambe-Coca Ecological Reserve (Cisneros-Heredia and McDiarmid, 2006).
