Biological Safety and Functional Properties of Açaí Seed Extract: Antioxidant Capacity and Prebiotic Potential

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT Açaí (Euterpe oleracea) is widely recognized as a functional food due to its nutritional value and abundance of bioactive compounds. Its seeds, representing approximately 80%–95% of the fruit mass, constitute an abundant agro‐industrial byproduct with promising biotechnological potential.

Digestive proteases from wild and farmed male morphotypes of the Amazon river prawn (Macrobrachium amazonicum) [PDF]

Journal of Crustacean Biology, 2014
The aim of this study was to characterize digestive proteases from wild and farmed morphotypes in males of Macrobrachium amazonicum (Heller, 1862). The hepatopancreas of wild and earthen pond reared specimens were collected and homogenized. Unspecific activities of trypsin, chymotrypsin and leucine aminopeptidase were determined using specific ...

The Guianese paradox: How can the freshwater outflow from the Amazon increase the salinity of the Guianan shore? [PDF]

, 2007
French Guiana is notable for the extent of its rain forests, which occupy 97% of the country, and the influence of the Amazon along its shores. In fact, the shores and estuaries support a mangrove forest typical of saline conditions.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Vanishing Treasures: Climate Change Steals Amazonian Coastal Livelihoods—A Cry from the Frontlines of Marajó Island

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
In our study, we demonstrate how climate change is degrading fisheries and forest resources in Marajó Island's coastal communities, where we found younger residents and urban‐proximate groups express the strongest concerns. We document how warming temperatures and erratic rainfall are threatening traditional livelihoods, food security, and cultural ...

Integrating curimba culture during the grow‐out phase of tambaqui affects overall productivity, water quality, and fish health

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract The efficiency of feed use in aquaculture may be improved by integrating the culture of extractive species into fed‐species systems. This study assessed the impact of including curimba (Prochilodus lineatus) in tambaqui (Colossoma macropomum) production during the grow‐out phase in earthen ponds.

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the
