Trophic ecology of the demersal predator Brazilian flathead Percophis brasiliensis (Percophidae) in a coastal upwelling ecosystem, SW Atlantic

This dataset contains the digitized treatments in Plazi based on the original journal article Bauer, Arthur de Barros, Fischer, Luciano Gomes (2024): Trophic ecology of the demersal predator Brazilian flathead Percophis brasiliensis (Percophidae) in a coastal upwelling ecosystem, SW Atlantic. Neotropical Ichthyology 22 (2): e 230115, DOI: 10.1590/1982-0224-2023-0115, URL: doi.org/10.1590/1982-0224-2023-0115 Upwellings are important oceanographic processes that induce several changes in marine ecosystems, including in the benthic-pelagic coupling (BPC) that plays a major role in coastal areas.

However, there is little available information about the possible effects of coastal upwellings on the trophic role of predators and in the BPC. Thus, here we investigate possible seasonal and ontogenetic changes in the trophic interaction of a demersal predator, the Brazilian flathead Percophis brasiliensis, from an upwelling ecosystem. Sampling was carried out for one year during two coastal upwelling events.
