Amino Acids in the Natural Food Web of Global Fishponds: Way Forward for Precision Protein Feeding in Pond Cyprinid Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Natural food webs in freshwater pond ecosystems provide an important nutritional foundation for cyprinid aquaculture, yet information on their protein and amino acid composition remains fragmented. This review synthesized published data from 30 studies (1950–2026) reporting protein and indispensable amino acid (IAA) composition of freshwater ...

Microbially Mediated Intracellular Barite Mineralization: Evidence From an Early Ediacaran Microfossil in the Doushantuo Formation of South China

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.

Microbial communities mediating algal detritus turnover under anaerobic conditions [PDF]

open access: yesPeerJ, 2017
Background Algae encompass a wide array of photosynthetic organisms that are ubiquitously distributed in aquatic and terrestrial habitats. Algal species often bloom in aquatic ecosystems, providing a significant autochthonous carbon input to the deeper ...
