Using Nuclear Genomic Data to Address Intractable Relationships and Gene Tree Discordance in an Ancient Group of Gymnosperms (Ephedra, Gnetales)

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Low‐copy nuclear genes were used to address the notoriously difficult phylogeny of Ephedra. Additionally, we explored the potential effect of putative paralogy, intra‐locus recombination, and chimeric sequences on phylogenetic estimation. ABSTRACT The evolutionary history of Ephedra L.

Cytogenetic Analysis of Altitude‐Associated Chromosome Variations in Campeiostachys nutans From Western Sichuan Plateau Using Multicolor GISH and ND‐FISH Approaches

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
The genomic and chromosomal organization of C. nutans was investigated using GISH and ND‐FISH with four oligonucleotide probes. The results showed that repetitive sequence distribution exhibited genome‐specific patterns: the H genome demonstrated high structural stability with low polymorphism, while the St genome showed moderate variation, and the Y ...

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Aquatic macrophytes as nature‐based solutions: Challenges and opportunities across inland and coastal waters

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Macrophytes are foundation species whose use as nature‐based solution (NbS) in aquatic ecosystems can help reduce climate change impacts while mitigating biodiversity loss. The discrepancy in research and application of macrophytes as NbS across inland and marine coastal ecosystems is an opportunity to expand the concept and learn from ...
