Hyloscirtus lindae


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Hyloscirtus lindae
Species Authority: (Duellman and Altig, 1978)
Taxonomic Notes: This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-10-27
Assessor(s): Diego Almeida, Wilmar Bolívar, Luis A. Coloma, Santiago Ron
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
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 in the Ecuadorian and Colombian Andes.
2004 Vulnerable

Geographic Range [top]

Range Description: This species occurs on the Amazonian slopes of the Andes in southern Colombia (in Caquetá and Putumayo Departments) and Ecuador (south to Morona Province). It ranges from 2,000-2,600m asl.

Population [top]

Population: It is a common species.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It lives in upper humid montane forest, and it also survives in pastureland and other altered habitats. However, although it is adaptable, it probably cannot tolerate extremely severe habitat clearance, leading to a very open landscape. It is associated with creeks and breeds in streams. Individuals have been found on vegetation along small creeks within forests; tadpoles have been collected in bodies of water with limited movement (Mueses-Cisneros, 2005).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threats are habitat loss from agricultural development, planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. The species has a narrow altitudinal range, and lives in habitats where catastrophic extinctions have occurred in other frog species with stream-dwelling tadpoles, perhaps due to chytridiomycosis. Mueses-Cisneros (2005) reports that all tadpoles examined in his study lack keratin in their mouthparts; however, he suggests that this is not necessarily related to chytrid infection.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas in Ecuador, including Parque Nacional Llanganates and Parque Nacional Sangay, but is apparently not recorded from any in Colombia. There is a need for close population monitoring of this species, given the potential threat of chytridiomycosis.
