Resilience in the heights: Elevational filtering preserves taxonomic and functional beta diversity over time against biotic homogenization

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental heterogeneity generates taxonomic and functional beta diversity, but a key question regards whether heterogeneity can maintain functional diversity when global change causes range shifts, potentially causing biotic homogenization by favouring species ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Responses of Soil Arthropod Communities to Varying Shading Levels in Agriphotovoltaic Systems

open access: yesIntegrative Zoology, EarlyView.
Soil fauna was primarily influenced by crop type and season rather than AgriPhotovoltaic (APV) panels. Elevated panels increased soil temperature and soil organic matter in early wheat stages, while shading enhanced soil moisture for tomatoes, benefiting moisture‐sensitive taxa.
