Habitat and Ecology

Habitat and Ecology
B. posadae is a benthopelagic (ecological region at the lowest level of water body) species. Plant material is an important part of the diet of adult Brycon species; and thus these fish play a role in the dispersal of plants whose fruits they eat (Berra 2001).

Justification
Very little is known about the species. The species could potentially be threatened but the area in which it is distributed is so inaccessible that no inferences can be made. Coupled with its cryptic habits, it is difficult to infer anything about the species, so it is assessed as Data Deficient.

Threats

Major Threats
Due to their dependence on plant material in their diet, the destruction of rainforests surrounding their habitat could have serious consequences for this species. The areas that the species occurs in are unlikely to be particularly heavily impacted.
