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 (...

A Spatial-Domain Crest-Line Tracking Method for Swell-Based Shallow-Water Bathymetry Retrieval from Sentinel-1 SAR Imagery

Shallow-water bathymetry is essential for coastal dynamics, navigation, engineering, and marine-resource management, especially where in situ observations are sparse. This study proposes a wave-stripe-based method for shallow-water bathymetric retrieval from Sentinel-1A VV-polari...

A helix-loop-helix gene orchestrates male fate in common carp

Fish show exceptional diversity in sex-determination mechanisms, making them a powerful system for studying how these pathways evolve. However, no definitive master sex-determining gene has yet been identified in Cyprinidae, a widely distributed and species-rich fish family. Here...

Efficient complete coverage path planning for mining vehicles in complex environments via region decomposition and finite-state control

Complete coverage path planning for deep-sea mining vehicles is difficult because large mining areas require coordinated planning across multiple spatial scales, while dense and irregular obstacles can readily induce coverage deadlocks. This paper proposes a three-tier hierarchic...

Genome-Wide Association Study of Spawning Traits and Candidate Gene Mining in Portunus trituberculatus

Portunus trituberculatus is a commercially crucial marine aquaculture crab species in China, renowned for its high economic value. Spawning performance is one of the most important target traits in selective breeding programs for this species; however, the genetic architecture un...

Apiin from sugarcane leaves modulates postprandial hyperglycemia by targeting dipeptidyl peptidase IV, α ‐amylase, and α ‐glucosidase

Abstract BACKGROUND Postprandial hyperglycemia is a metabolic abnormality that can emerge early in the progression toward type 2 diabetes and is closely associated with insulin resistance. Sugarcane leaves, an underutilized by‐product of sugar production, are rich in flavonoids a...

Physics-constrained and peak-aware hybrid deep learning for ultra-short-term photovoltaic power forecasting

Accurate prediction of ultra-short-term photovoltaic (PV) power is crucial for ensuring the safe and stable operation of the power grid and promoting the efficient integration and utilization of renewable energy. Existing data-driven models have significant limitations in handlin...

Chronic carbonate alkalinity exposure impaired the mechanical properties of exoskeleton and the intestinal microbiota of juvenile Macrobrachium rosenbergii

Along with the global expansion of saline-alkali aquaculture, understanding the physiological adaptation of economically important species like Macrobrachium rosenbergii to alkaline stress is essential for sustainable aquaculture production. This study investigated the effects of...

Development and application of a low-density 10 K liquid SNP array for genetic improvement in large yellow croaker (Larimichthys crocea)

Developing cost-effective and scalable genotyping platforms is essential for expanding germplasm identification and genomic breeding in aquaculture. However, the high cost of genotyping remains a major constraint on the large-scale application of these approaches in large yellow...

Arachidonic Acid Enhances Reproductive Performance and Oocyte Quality of Female Blotched Snakehead (Channa maculata) via Activation of the TGF-β/Smad Signaling Pathway

Arachidonic acid (ARA) is an indispensable fatty acid for aquatic organisms, playing critical roles in reproductive physiology. This study aimed to evaluate the effects of graded dietary ARA levels on the reproductive performance, tissue fatty acid profiles, plasma sex hormone an...

Plastisphere microbial succession and predicted functional responses: a 60-day temporal study in wastewater effluent

Abstract Although wastewater treatment plants (WWTPs) achieve high microplastic removal efficiency, substantial quantities are still discharged, and the long-term dynamics of plastisphere microorganisms on their surfaces and potential impacts on receiving waters remain poorly und...

Effect of Nano- and Microparticulate Fermented Fish Protein Hydrolysate Diets on Growth, Digestive Function, Intestinal Development, and Gene Expression in Common Carp (Cyprinus carpio) Larvae

The early larval stage is a major bottleneck in freshwater aquaculture because conventional live feeds are not always available for optimum nutrient availability and digestibility to satisfy the nutritional requirements of developing larvae. This study evaluated the effects of mi...

A Geometry-Aware Framework with Dynamic Edge Relation Modeling for Underwater Fish Perception and Non-Contact Body Size Estimation

Accurate underwater fish perception is a prerequisite for intelligent aquaculture, providing essential support for automated growth monitoring and precision feeding. Nevertheless, underwater imaging is severely affected by light scattering and cluttered backgrounds, making reliab...

Development of an Olfactory Receptor (OR5K1)-Based Biosensor for Pyrazine Detection in Foods
