Genetic diversity and population structure of the Asian yellow pond turtle (Mauremys mutica)

To investigate the genetic diversity and structure of farmed Asian yellow pond turtle ( Mauremys mutica ), we performed whole-genome resequencing on 180 individuals collected from eight farms spanning six regions in China. A total of 2072,663,419 single nucleotide polymorphisms (...

Comparative Bioaccumulation of Mineral Elements in Soft Tissues, Shells, and Pearls of Sinohyriopsis cumingii (Lea, 1852) Cultured for Non-Nucleated, Visceral Mass-Nucleated, and Mantle-Nucleated Pearls

The triangle sail mussel Sinohyriopsis cumingii (Lea, 1852) is the world’s leading producer of freshwater pearls. Mineral elements are key components of pearls and affect pearl quality, but their bioaccumulation patterns in the soft tissues, shells, and pearls of this species rem...

Orbital Coupling Over N‐Bridged Zn─Co Atomic Pairs Enables Lignocellulose Valorization

ABSTRACT Production of monophenols and carbohydrates through reductive catalytic fractionation is the key operation for lignocellulose utilization. Metal utilization can be maximized by single‐atom catalysts, but catalytic performance is limited by the insufficient activation cap...

Low‐Crystalline Ag 1.2 V 3 O 8 : A Zinc‐Ion Storage Cathode With an Ultrahigh Capacity of 525 mAh g −1 Enabled by Oxygen‐Vacancy‐Rich Coordination Environments

ABSTRACT Conventional vanadium‐based cathodes are limited by sluggish Zn 2+ transport, poor electronic conductivity, and incomplete utilization of redox‐active sites. Here, redox‐active Ag serves as a regulator of local coordination chemistry in a short‐range‐ordered low‐crystall...

Genome-wide association analysis reveals SNPs and candidate genes associated with thermal tolerance in the Yesso scallop (Patinopecten yessoensis)

The Yesso scallop ( Patinopecten yessoensis ) is a commercially important aquaculture species in northern China. However, as a cold-water species, it has been severely impacted by the continuous rise in seawater temperatures caused by global warming. Frequent high summer temperat...

Metabolomic Signatures Uncover Domestication-Driven Hypoxia Tolerance in Common Carp (Cyprinus carpio)

Hypoxia represents a pervasive selective pressure in aquaculture systems, prompting aquatic organisms to develop distinct tolerance strategies through diverse physiological and biochemical responses. The common carp (Cyprinus carpio), a species characterized by extensive geograph...

A Passive High‐Pass Negative Group Delay Circuit With Low Insertion Loss and Enhanced Delay Magnitude

ABSTRACT A passive high‐pass negative group delay circuit (NGDC) based on lumped RLC networks is proposed and verified in this paper. Five high‐pass NGD topologies are first designed and evaluated under identical port impedance and frequency conditions. Among them, the Type IV to...

Effects of Different Farming Models on Muscle Nutrients, Muscle Transcriptome and Intestinal Microbiota in Pelodiscus sinensis

Farming models profoundly influence the biological traits of aquatic organisms. This study compared muscle nutrients, muscle transcriptome, and gut microbiota of Pelodiscus sinensis reared under rice-field and pond conditions. Compared with the pond group (Group P), the rice-fiel...

Study on the Accumulation, Excretion, and Distribution of Cadmium in Mice After Dietary Exposure to Cadmium-Rich Swimming Crab Portunus trituberculatus

To investigate the patterns of cadmium accumulation and distribution in mice following oral ingestion of cadmium-enriched Portunus trituberculatus, this study selected 4-week-old ICR mice as a model organism. A control group was fed a standard diet, while an exposure group was fe...

Physiological, Transcriptomic, and Metabolomic Insights into Ammonia-Nitrogen Stress in the Hepatopancreas of Litopenaeus vannamei Acclimated to Low Salinity

Elevated ammonia nitrogen significantly reduces the survival rate of Litopenaeus vannamei under low-salinity conditions. Low-salinity culture is widely adopted in shrimp farming but susceptible to ammonia accumulation; however, relevant studies mainly focus on juvenile shrimp und...
