Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Sclerophyllous structural and chemical traits of mite‐induced galls on Crinodendron patagua (Elaeocarpaceae) leaves

open access: yesPlant Biology, Volume 28, Issue 6, Page 2039-2053, October 2026.
Eriophyid mites reprogram the structural and biochemical traits of sclerophyllous leaves in Crinodendron patagua, promoting the formation of nutrient‐rich and protective gall tissues. Abstract Sclerophyllous plants present a suite of traits, including small, leathery leaves with thick cuticles, dense trichomes and sclerified tissues, which are often ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2346-2367, September 2026.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Ex vitro standardization enables evaluation of phosphorus‐use strategies in Pampa biome grasses

open access: yesJournal of Environmental Quality, Volume 55, Issue 5, September/October 2026.
Abstract Native grasses of the Pampa biome are essential for ecosystem functioning and restoration, yet understanding of how native species respond to nutrient availability remains limited by challenges in standardizing plant material for controlled experiments.
