Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

Ecography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

Medical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

New Phytologist, EarlyView.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

Thermal Stress Is Associated With Fragmentation of Mediterranean Posidonia oceanica Meadows

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
By combining a physiological model of cumulative thermal stress with AI‐based seagrass mapping, we show that chronic sublethal warming is associated with fragmentation of Mediterranean Posidonia oceanica meadows and increased regression risk by 2100. ABSTRACT Posidonia oceanica meadows, which underpin Mediterranean coastal ecosystems, are undergoing ...

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5921-5933, 15 August 2026.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...
