Genetic Relationship and Diversity of Ellochelon vaigiensis in the Vietnamese Mekong Delta Using Cytochrome b Gene Sequences

Ecology and Evolution, Volume 15, Issue 6, June 2025.
This study investigated the genetic diversity and phylogenetic relationships of Ellochelon vaigiensis in the Vietnamese Mekong Delta using cytochrome b (Cytb) gene sequences. Analysis of 12 samples from four locations revealed high haplotype diversity (Hd = 0.79) but low nucleotide diversity (π = 0.004), with minimal genetic differentiation among ...

Phylogenetic Variation of Periophthalmus Species Living in the Mekong Delta, Vietnam, Using Cytb Sequence

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study investigates the genetic relationships of three Periophthalmus mudskipper species (P. chrysospilos, P. gracilis, and P. variabilis) from the Mekong Delta using mitochondrial cytochrome b (Cytb) gene analysis. The findings reveal significant interspecific genetic divergence (15%–18%) and distinct phylogenetic sub‐clades supported by ...

Discovery and biological characterization of a novel mesoionic insecticide fenmezoditiaz

Pest Management Science, Volume 81, Issue 5, Page 2535-2552, May 2025.
Acetylcholine binding protein (AChBP) from the sea slug Aplysia californica was modified using site‐directed mutagenesis to create an insect‐like binding site enabling structure‐based compound design. Fenmezoditiaz is a systemic insecticide with a broad spectrum, lack of cross‐resistance and an additional tool for integrated pest management and ...

Effect of Pore Water Pressure Ratio on Stability of Wind Turbine Shallow Foundations on Saturated Sandy Soil Due to Soil Liquefaction: A Case Study in Coastal Area of Soc Trang Province, Vietnam

Iraqi Geological Journal
Wind turbines are structures whose operation is always affected by dynamic loads. Currently, shallow foundations are common for onshore wind turbines. In the case of saturated sandy soils, dynamic stresses caused by wind turbines can cause the sand to ...

Artemia Cyst Production in Solar Earthen Ponds in Vinh Chau, Vietnam, and Its Associated Microbiome

Aquaculture Research, Volume 2025, Issue 1, 2025.
Artemia franciscana farmed in Vinh Chau, Vietnam, have been known for their premium‐quality cysts. This study provides an update on Artemia cyst production in solar earthen ponds in Vinh Chau and explores the microbiome of Artemia gut, pond water, and pond sediment in order to generate clues for research on cyst productivity improvement.

Morphological Variation of the Fiddler Crab Tubuca paradussumieri (Decapoda: Ocypodidae) Among Provinces in the Vietnamese Mekong Delta and a Classification Key for Genus Tubuca

International Journal of Zoology, Volume 2025, Issue 1, 2025.
Although Tubuca paradussumieri​ (Decapoda: Ocypodidae) is an essential species in tropical mangrove ecosystems, little is known about how its intraspecific morphology varies depending on the habitat. Clarifying local adaptations, resource partitioning, and biodiversity patterns in vulnerable coastal ecosystems requires understanding these variances ...

Optimal Ignition Timing Prediction Based on Premixed Ratio and Combustion Duration Using the Multiple Vibe 2‐Zone Combustion Model

Journal of Engineering, Volume 2025, Issue 1, 2025.
The depletion of fossil fuel supplies and the harmful environmental effects of combustion have emerged as significant issues. One viable approach to address these challenges is optimizing fuel injection timing to improve diesel engine performance. This work studies the effects of ignition timing (IT) and premixed ratio (PR) on the performance of a ...
