Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA BUFONIDAE

Scientific Name: Rhinella magnussoni
Species Authority: Lima, Menin and Araújo, 2007
Taxonomic Notes: Rhinella magnussoni can be distinguished from other similar species by a combination of morphological features (in both adults and tadpoles), acoustic features and reproductive behaviour (Lima et al., 2007).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Albertina P. Lima
Reviewer(s): Ariadne Angulo and Simon Stuart
Justification:
Listed as Least Concern in view that it occurs in an area of extensive, suitable habitat, some of which is within a protected area, its presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Population [top]

Population: This is considered to be a common species in the western region of Pará, between Santarém and Ruranópolis (A.P. Lima, pers. comm. 2008).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species is found in lowland Amazon terra firme rainforest (A.P. Lima, pers. comm. 2008). Males call frequently during daylight hours from within leaf-litter distant from streams or terrestrial pools. Oviposition sites are pools of water that form on fallen tree trunks, these can contain tadpoles of R. magnussoni in more than one developmental stage. Tadpoles can also eat eggs. Calling males apparently exhibit site fidelity, returning to call at the same place after being caught and handled. Reproduction appears to be seasonal and occurs between January and March. At night, males and females rest on vegetation at 30 to 150 cm above ground. Rhinella magnussoni occurs in sympatry with R. castaneotica, another member of the R. margaritifera species group (Lima et al., 2007).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The species occurs within a relatively large protected area, but a regional threat is extensive deforestation (A.P. Lima, pers. comm. 2008).

Conservation Actions [top]

Conservation Actions: The species has been seen and heard at the federal reserve of Floresta Nacional do Tapajos (Lima et al., 2007).
