Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

Power Through Visibility: How Policy Narratives Matter in Climate Change Debate on X

open access: yesPolicy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Research on policy narratives has shown that political actors employ certain narrative strategies in their competition for attention. Although we know that actors' narrative strategies coincide with existing power constellations (e.g., government vs. opposition), the ways in which they influence public attention remain largely unknown. In this
