Scientific Name: Mantidactylus charlotteae Vences & Glaw, 2004
Taxonomic Source(s): Frost, D.R. 2015. Amphibian Species of the World: an Online Reference. Version 6.0. New York, USA. Available at: http://research.amnh.org/herpetology/amphibia/index.html.
Taxonomic Notes: This species was separated from Mantidactylus albofrenatus (Vences and Glaw 2003). The taxonomy of this species complex is in need of taxonomic revision (F. Glaw pers. comm. May 2016).

Geographic Range [top]

Range Description:This species from eastern Madagascar occurs widely in the coastal rainforest belt from Marojejy southwards, possibly as far as Andohahela, between 0-600 m asl. The map is very provisional as this is an unresolved taxonomic complex (F. Glaw pers. comm. May 2016).
Countries occurrence:
Native:
Madagascar

Population [top]

Population:It is a very abundant species. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial species, often found near streams, usually in pristine or only slightly disturbed rainforest. It breeds in streams and the eggs are presumably laid on land.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements.

Species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd), however currently there have been no negative effects observed within amphibian populations in Madagascar suggesting the Bd strain has a low virulence level (Bletz et al. 2015).

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species occurs in several protected areas.

Research Needed
Further research is needed to resolve the taxonomy of this species (F. Glaw pers. comm. May 2016). and is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al. 2015).
