Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.Abstract Aflatoxin B1 (AFB1) contamination of aquaculture feed poses serious health risks to fish and consumers. In this study, the efficacy of a novel anti‐mycotoxin agent specific for aquatic species (AM‐AQ) containing bentonite, sepiolite, and orange peel meal (Citrus Sinensis) in alleviating AFB1 toxicity in Nile tilapia (Oreochromis niloticus) was

Cryptic Variation in Morphological Evolution: HSP90 as a Capacitor for Loss of Eyes in Cavefish [PDF]
, 2013 In the process of morphological evolution, the extent to which cryptic, preexisting variation provides a substrate for natural selection has been controversial. We provide evidence that heat shock protein 90 (HSP90) phenotypically masks standing eye-size

Environmental DNA, Volume 8, Issue 1, January–February 2026.This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.
