Evaluation of the Population Genetic Structure of Anadara tuberculosa (Mollusca, Bivalvia) in the Panamanian Pacific

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Our study analyzed the population genetics of Anadara tuberculosa (concha negra) in five Panamanian Pacific mangrove areas using the mitochondrial COI gene. We found high haplotypic diversity and low nucleotide diversity, a pattern that suggests a recent demographic expansion, which was supported by our neutrality tests and a star‐shaped haplotype ...

Site suitability analysis for Bay scallop aquaculture and implications for sustainable fisheries management in the Ha Long Bay archipelago, northern Vietnam

Journal of Natural Resources and Development, 2013
Mollusc culture if properly managed, may help decrease capture fisheries over-exploitation in Vietnam, and possibly become an alternative income for local fishermen. The definition and characterization of zones suitable for aquaculture is pivotal for its

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.

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 ...

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 ...

Cytogenetic characterization of the bay scallop, Argopecten irradians irradians, by multiple staining techniques and fluorescence in situ hybridization

Genes & Genetic Systems, 2007
The chromosomes of Argopecten irradians irradians were studied by various cytogenetic approaches. Conventional chromosome characterization built on C-banding, DAPI-staining, and silver staining was complemented by the physical mapping of ribosomal DNA and telomeric sequence (TTAGGG)n by FISH.

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.

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.

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 ...
