Scientific Name: Adelophryne maranguapensis
Species Authority: Hoogmoed, Borges & Cascon, 1994

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Débora Silvano, Diva Borges-Najosa
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat on the Serra de Maranguape.

Population [top]

Population:It is abundant in certain parts of its small range and is regularly recorded.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a diurnal species that lives in the leaf-litter of primary and secondary forest, and has also been found in bamboo and banana plantations, as well as forest fragments (but not open habitats). It is a direct developer, and the eggs are probably laid on the ground.

Threats [top]

Major Threat(s): The Serra de Maranguape is being very heavily deforested, due to logging, agriculture, and human settlement.

Conservation Actions [top]

Conservation Actions: It is not found in any protected areas, and the formal protection of remaining forest and forest fragments in the Serra de Maranguape is urgently needed.
