Population dynamics and reproductive features of the Amazon River prawn Macrobrachium amazonicum (Heller, 1862) in Neotropical reservoirs under drought events

Belgian Journal of Zoology
Here, we describe population and reproductive dynamics of four populations of Macrobrachium amazonicum in reservoirs during drought events. Additionally, we analyze possible phenotypic changes in this species promoted by fish predation.

Oxidative Stress Biomarkers in the Shrimp Macrobrachium amazonicum (Heller, 1862): Assessment in an Environmental Preservation Area in the Brazilian Amazon

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities generate a significant amount of pollutants that are released into the environment, causing physiological and ecological disturbances. Among the xenobiotics present in aquatic ecosystems, numerous chemical and organic compounds have oxidative potential or are metabolized through oxidative processes, which may amplify ...

Daily rhythm of feeding activity and the ability of Amazon River prawn (Macrobrachium amazonicum) to control its protein intake using self-feeders

Aquaculture International
Self-feeding systems have been used to study aquatic animals’ behavior, suggesting initial studies for practical diet design. This study aimed to identify gaps in knowledge of the behavior, feeding rhythms, and target protein intake of the Amazon River ...

Ecotoxicological Assessment of Mercury in Fish From a Gold‐Mining‐Impacted Amazonian River: Biomonitoring and Human Health Risk

Environmental Toxicology, EarlyView.
ABSTRACT The Peixoto de Azevedo River, located in northern Mato Grosso, southern Brazilian Amazon, has a long history of artisanal and small‐scale gold mining (ASGM). This study evaluated total mercury (THg) concentrations in fish tissues to assess biomagnification and potential risks.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Integrating Aquaponics with Macrobrachium amazonicum (Palaemonidae: Decapoda) Cultivation for the Production of Microgreens: A Sustainable Approach

AgriEngineering
The use of aquaponic systems has grown in recent years, but few of these systems have integrated the production of prawns and short-cycle vegetables. This study evaluated the potential for producing microgreens (beet, amaranth, arugula, and red cabbage ...

The Unfolding Desert: Observed Structural Drying and Projected Aridity Risks in a Brazilian Family Farming Citizenship Territory

Land Degradation &Development, Volume 37, Issue 15, Page 10944-10959, September 2026.
ABSTRACT Aridification in Semiarid regions is a recurring theme in Intergovernmental Panel on Climate Change (IPCC) reports and has been documented in Northeastern Brazil. This study analyzes the spatiotemporal dynamics of aridification in the Lower São Francisco River “Citizenship Territory” (Sergipe and Alagoas) at a fine spatial resolution (~1 km ...
