Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA CENTROLENIDAE

Scientific Name: Centrolene geckoideum
Species Authority: Jiménez de la Espada, 1872
Taxonomic Notes: In spite of its Amazonian type locality, this species is in fact known only from the Andes.

Assessment Information [top]

Red List Category & Criteria: Vulnerable A3c; B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia, Erik Wild, Mario Yánez-Muñoz
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Vulnerable because of a population decline, estimated to be more than 30% over the next ten years, projected from shrinkage in distribution, habitat destruction and degradation, and climate change; and 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.

Geographic Range [top]

Range Description: This species occurs in all three Cordilleras of Colombia from Antioquia, Caldas and Boyaca Departments, south to the north-western Andean slopes of Ecuador in Carchi and Pichincha Provinces. It has been recorded between 1,750 and 2,500m asl.

Population [top]

Population: It is localized, but can be conspicuous in its microhabitat. In Ecuador, the population at Quebrada Zapadores (Pichincha Province) appears to have disappeared.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits cloud forest, where it can be found on vegetation next to running water or on rocks in streams and behind waterfalls. The eggs are placed on boulders in the splash zone of fast-flowing streams and waterfalls. It is a very territorial species, and the males guard the eggs. It is very susceptible to deforestation, and does not survive in degraded habitats.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is habitat loss and deforestation, as a result of agricultural development (particularly the planting of illegal crops), logging, and human settlement. Other threats include the introduction of alien predatory fish in streams, and pollution resulting from the spraying of illegal crops. Like some other species in its family, it might also be affected by the movement of the cloud layer up the mountain sides as a result of climate change, resulting in reduced humidity within the altitudinal range of the species (probably exacerbated by habitat fragmentation). Chytridiomycosis also cannot be ruled out as a potential threat.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas in Colombia, but none in Ecuador. Further introductions of predatory alien fish should be prevented. The species is in need of close population monitoring given the potential threat of chytridiomycosis.
