A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

Integrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

Plant Functional Groups Mediated the Effects of Plateau Pika Disturbance and Mowing on the Community Stability of Alpine Meadow Plants

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The response mechanisms of plant community composition, functional group biomass, vegetation‐soil properties, and community stability to plateau pika and mowing disturbance intensity exhibited distinct differences. Gramineae and Sedge aboveground biomass and soil nutrient content demonstrated more pronounced responses to both disturbances and their ...

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

Ecology 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 ...

Sharing landscapes with wildlife: Conflict and coexistence between high nature value pastoral systems and large carnivores

People and Nature, Volume 8, Issue 7, Page 2006-2017, July 2026.
Abstract High nature value (HNV) pastoral systems, that is those maintained by herding, transhumance and extensive grazing practices, are recognised as cornerstones of European biodiversity, cultural heritage and ecosystem service provision. Yet these systems are currently under significant pressure from a range of economic, social and environmental ...
