Rising Heat Traps Stem-Nesting Bees in Climate Crisis

Bee species that nest inside plant stems face the greatest short-term risk from increasing temperatures, while ground-nesting bees remain better able to evade extreme heat. This disparity matters because stem-nesting bees are critical pollinators whose survival is now directly threatened by the very climate shifts they help sustain. The broader implication is an urgent need for targeted conservation strategies to protect specific bee lineages before they face local extinction.
