Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA MANTELLIDAE

Scientific Name: Gephyromantis azzurrae
Species Authority: Mercurio & Andreone, 2007

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2009
Date Assessed: 2009-05-29
Assessor(s): Andreone, F., Vences, M. & Cox, N.
Reviewer(s): Hoffmann, M. & Angulo, A.
Justification:
Listed as Endangered because its extent of occurrence is less than 5,000 km², the area of occupancy is believed to be less than 500 km², all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat.
History:
2008 Endangered (IUCN 2008)
2008 Endangered

Geographic Range [top]

Range Description: This species is currently known from only three localities (Andriamanero, Iamabahatsy and Sakamalio) in the northern part of the Isalo Massif, between 640 and 689 m asl (Mercurio and Andreone 2007). It might occur a little more widely in the Isalo Massif. It is inferred that the potential distribution includes forest habitats along streams of the Isalo area, within and outside the protected areas boundaries (Andreone et al. 2008, Mercurio et al. 2008).

Population [top]

Population: There is little information, although individuals were found in suitable gallery forest habitat calling 10-20 m from each other (Mercurio and Andreone 2007). It is presumed that the population is declining with the associated continuing habitat loss.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species has been found in large canyons with running water in the river bed between stones, as well as in the gallery forest. Calling males were observed at night on leaves in the forest at about 50–150 cm above the ground (Mercurio and Andreone 2007). Its breeding is not known, but is presumably by larval development in streams.
Systems: Terrestrial; Freshwater

Use and Trade [top]

Use and Trade:

There is no information currently available on any possible uses of this species.

Threats [top]

Major Threat(s): On of the known localities, Andriamanero is outside the boundaries of the Parc National de l’Isalo. Threats affecting this area include the extensive prairie burning leading to the loss of gallery forest, and habitat alteration due to the excavation of mines for sapphires, an activity that has a great potential for long-term persistence and is thus seriously threatening the Isalo biodiversity (Duffy 2006).

Conservation Actions [top]

Conservation Actions: Two of the know localities, Iamabahatsy and Sakamalio, are within the Parc National de l’Isalo. Outside this protected area conservation measures are needed to protected the species' habitat from the effects of fires and mining.
