The Role of Habitat, Climate, and Space in the Species and Traits Variation of Phytoplankton in Large Cascade Reservoirs. [PDF]
Phytoplankton beta diversity along cascade reservoirs of the Tocantins River is shaped by reservoir age, spatial arrangement, and environmental conditions. Younger, distant reservoirs show higher diversity, while intermediate ones tend toward homogenization. Environmental and spatial drivers differentially influence taxonomic and functional composition.

Intestinal responses in pacu (Piaractus mesopotamicus) exposed to fasting and refeeding nutritional management. [PDF]
Abstract Fasting is a practice in the aquaculture industry that aims to reduce feed costs. This practice can affect the gastrointestinal system of fish. The intestine plays a pivotal role in the nutrition and overall health of fishes. The present study sought to evaluate the effects of fasting and refeeding on body weight, intestine somatic index (ISI),

Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change. [PDF]
Rivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach. [PDF]
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.
