Phenology in winter‐deciduous relict Mediterranean forests as a tool to understand their adaptation to climatic seasonal cycles

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Winter deciduous forests signify a relict ecosystem that survives restricted to microclimatic zones of high mountains in the western Mediterranean Basin and they are well represented in the southern Iberian Peninsula (Sierra Nevada, Spain). Given the scarce knowledge of their phenological behaviour, the aim of this work was to obtain the annual ...

Robust passive sampling of airborne environmental DNA to monitor plants and animals

Methods in Ecology and Evolution, Volume 16, Issue 9, Page 2118-2130, September 2025.
Abstract Airborne environmental DNA (eDNA) is a rich resource for understanding biodiversity, but its wider application is hindered by its complex collection methods and unknown sampling time effects. To develop a passive sampling scheme that is effective and convenient, we systematically compared the performance of an array of materials, namely common

Torreya grandis Seed Polyphenols Protect RAW264.7 Macrophages by Inhibiting Oxidative Stress and Inflammation

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
Torreya grandis seed polyphenols (TGSP), primarily containing gallic acid and epicatechin, exhibit selective free radical scavenging activity. TGSP pretreatment effectively inhibits LPS‐induced inflammatory responses by reducing TNF‐α, NO, and IL‐6 production. TGSP also alleviates H2O2‐induced oxidative stress by enhancing antioxidant enzyme activities
