Ecologia de Hypopygus nijsseni

|---|---|
| Notas | In the Tefé region H. nijsseni was found rarely in small rainforest streams (approximately 1–4 m across and up to 1.5 m deep), where it was found in marginal roots and submerged structures, near conspecifics. A single specimen was found in shallow flooded forest in the floodplain of the Rio Tefé, in the lower reaches of a terra firme stream. Stomach contents (N = 5) contained only autochthonous aquatic invertebrates – mostly Chironomidae larvae, but also the larvae of Ephemeroptera, Coleoptera, and Trichoptera. Hypopygus nijsseni co-occurs syntopically with themuch more abundant H. lepturus without any obvious partitioning of microhabitat or diet. |
