The Role of Fish in Nutrient Recycling Across a Conservation Gradient in Neotropical Streams

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Fish play a crucial role in nutrient recycling within various aquatic ecosystems, but how their contribution varies across streams with different levels of disturbance remains poorly understood. In our study, we investigated the role of fish assemblage in nutrient cycling within eight Neotropical streams characterised by varying degrees of ...

Long‐Term Effects of Land Use and Cover Change and Dam Rupture on Ichthyofauna in a Neotropical Stream

open access: yesInternational Review of Hydrobiology, Volume 110, Issue 1, Page 5-12, June 2025.
ABSTRACT This study evaluates land use and land cover (LULC) changes and their impacts on the fish community of a neotropical stream in the Sorocaba River basin, Brazil, from 2006 to 2023. The watershed experienced landscape changes over time, categorized into four periods: rural interventions, urban interventions, restorative interventions, and post ...
