A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

Biotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.
