Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil

Journal of Fish Biology, Volume 108, Issue 2, Page 648-668, February 2026.
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

First Records of Length–Weight Relationships for Ten Fish Species From the Middle Stretch of the Uruguay River, Southern Brazil

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study estimated the length–weight relationships (LWRs) of 10 fish species from the middle stretch of the Middle Uruguay River basin, aiming to provide new morphometric data and contribute to the knowledge of Neotropical ichthyofauna. Fish were collected at seven sites with sampling conducted at each site during every season, totaling 84 sampling ...

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. We ask, how do Amazonian peoples

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

Histamine in Brazilian Foods: A Comprehensive Review of Occurrence and Risk Assessment for Intoxication and Intolerance

Food Science &Nutrition, Volume 13, Issue 11, November 2025.
Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...
