The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Insect Conservation and Diversity, Volume 19, Issue 5, Page 1114-1123, September 2026.Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...
