Amazonian fish migration as a social–cultural–ecological process

People and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences.

The Ecological Memory of Fish Assemblages in Tropical Agroecosystems With Different History of Landscape Changes

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Environmental changes can have persistent effects on the local and regional dynamics of multispecies assemblages. However, the extent of historical legacies on current diversity patterns may depend on the trajectory and intensity of the environmental change. Here, we investigate how persistent decadal land use and land cover (LULC) changes are

Local Environmental Variables Predict Fish Species Richness and Composition in Sand Beaches of a Neotropical River

River Research and Applications, Volume 41, Issue 9, Page 1949-1958, November 2025.
ABSTRACT Local and regional species diversity is influenced by historical factors, resource availability, biotic interactions, the presence of resources, and adequate environmental conditions. We evaluated the effects of local environmental variables and spatial structure on fish species richness and composition along sandy beaches of a Neotropical ...
