Craugastor bransfordii


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Craugastor bransfordii
Species Authority: (Cope, 1886)
Common Name(s):
English Bransford's Robber Frog
Eleutherodactylus bransfordii (Cope, 1886)
Eleutherodactylus costaricensis (Taylor, 1952)
Eleutherodactylus rearki (Taylor, 1952)
Hylodes bransfordii (Cope, 1886)
Lithodytes bransfordii Cope, 1886
Microbatrachylus bransfordii (Cope, 1886)
Microbatrachylus costaricensis Taylor, 1952
Microbatrachylus rearki Taylor, 1952
Taxonomic Notes: This species was previously within the genus Eleutherodactylus (Crawford and Smith, 2005). It ranges from Nicaragua to Costa Rica. However, the population endemic to Panama is now recognized to be distinct from C. bransfordii, but has yet to receive a formal name. Information about this taxon is included in the C. bransfordii account until a published name becomes available. Additionally, it is possible that specimens from northern Nicaragua currently referred to C. bransfordii might also represent a different taxon.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-12-23
Assessor(s): Bolaños, F., Solís, F., Ibáñez, R., Chaves, G., Savage, J., Jaramillo, C., Fuenmayor, Q. & Köhler, G.
Reviewer(s): Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
2004 Least Concern

Geographic Range [top]

Range Description: This species can be found in Eastern Nicaragua to central Costa Rica. In Costa Rica it is known from 60-880m asl. In Nicaragua it has been collected as high as 1,330m at Cerro Kilambé. The Panamanian taxon formerly included within C. bransfordii is found on the Atlantic versant of central Panama, from the lowlands to elevations approaching 2,000m asl. All populations currently referred to as C. bransfordii are included on the map.

Population [top]

Population: Several related species have been included in C. bransfordii in the past making it difficult to discern distribution and abundance from the literature. C. bransfordii is known to experience marked population fluctuations from year to year. The population at La Selva, Costa Rica, appears to have experienced a decline (Whitfield et al., 2007).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Craugastor bransfordii is associated with lowland moist and wet forests, premontane wet forest, and marginally in premontane rainforest; may be found in moderately disturbed areas. The Panamanian taxon is also present in these habitat types, although it is unclear as to whether or not it is tolerant of habitat disturbance. Both taxa are terrestrial, direct development species occurring in the leaf-litter layer.
Systems: Terrestrial

Threats [top]

Major Threat(s): General habitat loss by the destruction of natural forests is a threat to these taxa. At La Selva, declines seem to be driven by climate-driven reductions in quantity of standing leaf litter (Whitfield et al., 2007).

Conservation Actions [top]

Conservation Actions: Portions of the range of C. bransfordii are protected in national parks or protected areas of Costa Rica and Nicaragua. The Panamanian taxon is present within the protected areas of: area de manejo especial Nusagandi; Parque Nacional Chagres; Parque Nacional Soberania, and Parque Nacional Altos de Campana.
