Gill Adaptation of the Hong Kong Catfish (Clarias fuscus) to Chronic Heat Stress: Tissue Remodeling, Enhanced Antioxidant Defense and Immune Metabolism Regulation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Continuous high‐temperature culture altered the structure of gill tissue, enhanced antioxidant capacity, and promoted apoptosis C. fuscus. In response, the organism mitigates extensive apoptosis and strengthens its repair capacity by regulating immune and energy metabolism pathways.

Exposure to benzo[α]pyrene causes oxidative stress and cell damage in bay scallop Argopecten irradians

Aquaculture Reports, 2021
In the present study, bay scallop antioxidant response to acute exposure to the benzo[α]pyrene (BaP; a type of polycyclic aromatic hydrocarbon) was investigated. Scallops were exposed to doses of 0.5 and 1.0 µg/L (low-dose group) and 10 and 50 µg/L (high-

A Short‐Type Peptidoglycan Recognition Protein From Atrina pectinata (ApPGRP) Exhibits Dual Functions in Pattern Recognition and Antibacterial Defense

Aquaculture Research, Volume 2026, Issue 1, 2026.
Peptidoglycan recognition proteins (PGRPs) could serve as key pattern recognition receptors (PRRs) in the innate immune systems of invertebrates. In this study, a short PGRP, designated as ApPGRP, was identified and functionally characterized from the mollusk Atrina pectinata to investigate its roles in immunity. The ApPGRP gene was cloned and found to

Mechanistic insights into the active site and allosteric communication pathways in human nonmuscle myosin-2C

eLife, 2017
Despite a generic, highly conserved motor domain, ATP turnover kinetics and their activation by F-actin vary greatly between myosin-2 isoforms. Here, we present a 2.25 Å pre-powerstroke state (ADP⋅VO4) crystal structure of the human nonmuscle myosin-2C ...

Short- and long-term consequences of larval stage exposure to constantly and ephemerally elevated carbon dioxide for marine bivalve populations [PDF]

Biogeosciences, 2013
While larval bivalves are highly sensitive to ocean acidification, the basis for this sensitivity and the longer-term implications of this sensitivity are unclear.

Low pH Does Not Impact Reproductive Success but Leads to Negative Carry‐Over Effects Between Parents and Larvae in a Mediterranean Gastropod

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We investigated the long‐term effects of ocean acidification on reproduction and early development in the Mediterranean gastropod Hexaplex trunculus. While low pH did not affect spawning or reproductive output, it significantly delayed larval development and reduced the likelihood of reaching hatching, especially when parents were preconditioned to ...

Life in a post‐eelgrass world: Temporal compression of a spatial refuge from predation

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Spatial refugia offered by structurally complex habitats mitigate high rates of predation for many aquatic and terrestrial prey species. These refuges are particularly important for small juvenile marine invertebrates, for which predation often represents the greatest cause of mortality.

Nematopsis Schneider, 1892 in Nerite Gastropods From Saint Kitts, With a Phylogenetic Study of the Genus, and Placement Within the Phylum Apicomplexa Levine, 1970

Journal of Eukaryotic Microbiology, Volume 72, Issue 4, July/August 2025.
ABSTRACT The Apicomplexa are obligate unicellular parasites found in terrestrial and aquatic environments. Nematopsis are found infecting marine invertebrates in a life cycle involving mollusks and crustaceans. In the present study, mantle and muscle tissues from nerite gastropods were microscopically examined for Nematopsis using wet mounts and ...

Heat Stress Response in Ruditapes Decussatus: Transcriptional Regulation of Key Pathways and Novel SNPs in Antioxidant Genes

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Climate change is known to affect all levels of biology, setting at risk ecological balance. Among other organisms' groups, aquatic inhabitants, and particularly bivalves, are expected to be influenced to a greater extent owing to their inability to move to more mild temperatures.

Marine Diatom Skeletonema costatum Dietary Supplementation Improves Growth, Immunological Responses, Antioxidant Activities, Gene Expressions, and Digestive Enzymes of Shrimp Litopenaeus vannamei

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
This work highlighted the impact of dry concentrations (0, 1, 2, and 4 g/kg diet) of the marine diatom species Skeletonema costatum (SK0%, SK0.1%, SK0.2%, and SK0.4%, respectively) as an aquafeed additive on the postlarvae of Pacific whiteleg shrimp (Litopenaeus vannamei). During an 8‐week feeding trial, the impact of S.
