Metabolite Profiles and Antioxidant Activity of Dendrobium catenatum Under Simulated Wild Cultivation

Food Safety and Health, EarlyView.
Dendrobium catenatum grown under simulated wild cultivation showed significantly higher flavonoids and stilbenes, leading to enhanced antioxidant activity in both leaves and stems compared to facility‐grown plants. Integrated metabolomics, antioxidant assays, and network pharmacology identified Denbinobin as a key multi‐target antioxidant compound ...

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

Geological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

Grassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.
