Chloroplast Phylogenomics and Barcode Discovery in Medicinal Stachys Species Reveal Evolutionary Relationships and Adaptive Signatures

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study presents the first complete chloroplast genomes of two medicinally important Stachys species, S. persica and S. germanica. Comparative phylogenomic analyses revealed highly conserved genomes with lineage‐specific variations, identified hypervariable regions as candidate DNA barcodes, and detected signatures of positive selection in the petB ...

A comparison of PCR-based markers for the molecular identification of Sphagnum species of the section Acutifolia

Acta Societatis Botanicorum Poloniae, 2011
RAPDs, ISJs, ISSRs, ITS and katGs were applied to determine genetic relationships between common Sphagnum species of the section Acutifolia. Twenty populations were genotyped using ten ISJ primers, 12 pairs of katG primers, 10 ISSR and 10 RAPD primers ...

Primera cita de las tres especies de Oxycraspedus Kuschel (Coleóptera: Belidae) en Argentina y uso de un modelo predictivo para comparar su distribución potencial con el rango de su planta huésped, la Araucaria araucana [PDF]

, 2007
Se reportan por primera vez en Argentina las tres especies de Oxycraspedus Kuschel (Belidae: Oxycoryninae) y se añaden a su distribución en Chile. Estos gorgojos son de interés debido a su asociación con el pehuén Araucaria araucana, una especie de gran ...

The Evolution of Giant Clam Science: From Foundational Studies to Emerging Frontiers

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review synthesizes nearly two centuries of giant clam research, identifying dominant themes, knowledge gaps, and emerging opportunities. Ecology, physiology, aquaculture, genomics, and biomineralization dominate the field, whereas anatomy and biotechnology remain underexplored. Future progress requires stronger integration of genomics, physiology,

Improved RAPD Method for Candida parapsilosis Fingerprinting

Genes, 2023
Recently, methods based on the analysis of arbitrarily amplified target sites of genome microorganisms have been extensively applied in microbiological studies, and especially in epidemiological studies. The range of their application is limited by problems with discrimination and reproducibility resulting from a lack of standardized and reliable ...

Evaluating Fishing Ban Effectiveness Through Spatiotemporal Changes in Genetic Diversity of Parabramis pekinensis

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Based on spatiotemporal changes in the genetic diversity of Parabramis pekinensis populations in the lower Yangtze River (2022–2024), this study provides pioneering evidence that the 10‐year fishing ban has not only significantly enhanced genetic diversity but also effectively mitigated geographical barriers, thereby strengthening gene flow ...
