From rivers to museums: 28S rDNA as a tool for molecular identification of Amazon palaemonids prawns

open access: yesAnais da Academia Brasileira de Ciências
Abstract Morphological identification of Palaemonidae prawns often proves challenging due to the overlap in their characteristics. In this study, we evaluated the utility of 28S ribosomal DNA (rDNA) sequences as a molecular tool for accurately identifying prawns within this family.

Effect of Intensification on Grow Out of the Amazon River Prawn, Macrobrachium amazonicum

open access: yesJournal of the World Aquaculture Society, 2007
Abstract The effects of intensification on growth, survival, productivity, population structure, and distribution of harvested biomass in individual size classes of Macrobrachium amazonicum in semi‐intensive culture were evaluated. Postlarvae (0.01 g) were stocked in 12 ponds at densities of 10, 20, 40, and 80/m2 (three replicates per treatment) and ...

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

open access: yesJournal 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 ...

Macrobrachium amazonicum: an alternative for microbiological monitoring of aquatic environments in Brazil

open access: yesCiência Rural, 2014
This study aimed to evaluate the role of the Amazon River prawn, Macrobrachium amazonicum, as carrier of Candida spp., by analyzing the correlation between Candida spp. from these prawns and their environment (surface water and sediment), through M13-PCR

Competition and habitat filtering shape Neotropical canopy butterfly communities across a rainfall seasonality gradient

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract The stability hypothesis posits that stable environments provide species with predictable resources, where mechanisms that limit similarity, such as competition, are able to drive niche specialization and shape community composition. By contrast, variable and unpredictable environments are expected to allow only those species with appropriate ...

Comparing environmental impacts of native and introduced freshwater prawn farming in Brazil and the influence of better effluent management using LCA

open access: yes, 2015
Concern about environmental impacts of aquaculture and its interaction with natural resources is increasing. Thus, it is important for new production systems to use practices that reduce environmental impacts, such as choosing to farm native species from

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

open access: yesJournal 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.
