Atelopus franciscus


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Atelopus franciscus
Species Authority: Lescure, 1974
Common Name(s):
English Central Coast Stubfoot Toad
French Atélope De Guyane Francaise

Assessment Information [top]

Red List Category & Criteria: Vulnerable A3ce ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Jean Lescure, Christian Marty, Marga Born, Renaud Boistel, Robert Reynolds, Marinus Hoogmoed, Ross MacCulloch, Philippe Gaucher, Stefan Lötters
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Vulnerable because of a projected population decline, estimated to be more than 30% over the next ten years, inferred from declines in other Atelopus species in the same region, probably due to chytridiomycosis.

Population [top]

Population: It is a locally common species (Lescure and Marty 2001), and was recorded as recently as 2000.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species is found near fast-flowing small streams and creeks in lowland rainforest; it is not known from any disturbed habitats. Eggs are laid in the water and the tadpoles adhere to rocks.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): There are no current major threats. However, it is potentially at risk from chytridiomycosis, although it occurs at low altitudes (which might afford it a degree of protection from this disease). An illegal international pet trade exists for this species, but it is not a threat to the species as a whole.

Conservation Actions [top]

Conservation Actions: The range of the species includes several nature reserves. Continued population monitoring is required, especially in light of the potential threat of chytridiomycosis.
