REPRODUCTIVE ASPECTS OF THE PRAWN Macrobrachium amazonicum IN A CONTINENTAL POPULATION LIVING DOWNSTREAM OF A HYDROELECTRIC DAM

Boletim do Instituto de Pesca, 2020
The migratory behavior of females of the freshwater prawn Macrobrachium amazonicum (Heller, 1862) can indicate a strategy that optimizes the population establishment. With this idea in mind, we evaluated the reproductive biology of M.

Ontogenetic Variation in Ammonia Excretion during the Early Life Stages of the Amazon River Prawn, Macrobrachium amazonicum

Journal of the World Aquaculture Society, 2010
Dry mass (DM) and total ammonia‐N (TAN) excretion were determined in embryos, larvae (ZI–ZIX, Z = zoea ), and postlarvae (PL) at 1, 7, and 14 d after metamorphosis (PL1, PL7, and PL14) of Macrobrachium amazonicum. Animals in postmolt–intermolt (A–C) stages were sorted according to their developmental stages, and placed into incubation chambers (∼ 30 ...

Climate‐related drivers of migratory bird health in the south‐central USA

Biological Reviews, Volume 100, Issue 3, Page 1272-1293, June 2025.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

Biocultural Determinants of Mothers' Complementary Feeding Decisions in the Urban Brazilian Amazon

American Journal of Human Biology, Volume 37, Issue 5, May 2025.
ABSTRACT Objective Complementary feeding (CF) occurs during a critical period of infant growth and development with life‐long health implications. Despite international efforts, there remains significant variation in the adequacy of complementary diets across settings. In Brazil, there is marked variation in adherence to CF guidelines and infant growth

Temporal Demographic Patterns in Amazonian Upland Shrimps Related to Stream Hydraulics and Precipitation

Freshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Reports of seasonal patterns in reproduction are uncommon for Amazonian upland‐stream shrimps (Caridea: Palaemonidae), since changes provoked by heavy rainfall in these systems are not as marked as in large rivers. Differences in the proportion of ovigerous females throughout the year are subtle and seem to be more a result of responses to ...

Chemical composition and fatty acid contents in farmed freshwater prawns [PDF]

, 2013
The objective of this work was to evaluate the chemical composition and fatty acid contents of Amazonian and giant river prawns. After four-month farming, with the same diet for both species, palmitic and stearic acids were the main saturated fatty acids.

Management implications of human livelihood strategies on Madagascar's coastal landscapes

Conservation Science and Practice, Volume 7, Issue 3, March 2025.
Abstract The unsustainable harvest and consumption of wild animals destabilizes both wildlife populations and the human livelihoods that depend upon them. In coastal landscapes, the overexploitation of terrestrial resources can increase pressures on marine ecosystems, and vice versa.
