Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

open access: yesInsect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

open access: yesInsect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.

Perceiving Vegetation From Social Positions: Discourses on Plants in a Mediterranean Landscape

open access: yesSociology Lens, EarlyView.
ABSTRACT Understanding how vegetation is perceived, named and valued requires attention to the social positions from which these perceptions are produced. This article analyses vegetation perception from different social positions based on qualitative research conducted in the province of Jaén (Andalusia, Spain), a Mediterranean landscape characterized

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

open access: yesPlant, Cell &Environment, EarlyView.
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.
