Range Description

Rhinella magnussoni is known from the type locality, Highway 163, Km 89 (03.15313° S, 54.84216° W), Belterra municipality, near Santarém city, Pará state, Brazil. However, it has also been seen and heard calling in the Floresta Nacional do Tapajos, at km 72 on the BR 163 highway, Belterra municipality (Lima et al., 2007).

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).

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

Major Threats

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

Conservation Actions

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