Bees
New research on Australian native bees indicates that species nesting in plant stems are the most exposed to rising temperatures from climate change. Underground-nesting bees appear better able to avoid extreme heat. Tropical species also show particular vulnerability despite adaptations to warm conditions.

A hybrid population of honeybees in Southern California demonstrates natural resistance to Varroa mites, a major threat to bee colonies. Researchers at UC Riverside found these bees carry 68% fewer mites and require far less chemical treatment. The discovery, detailed in a new study, suggests early-life defenses in larvae may hold the key.
Scientists have identified natural antimicrobial compounds in pollen that could safeguard bee colonies against infections. The discovery, detailed in a recent study, highlights pollen's role beyond nutrition in bee health. This finding offers potential new strategies for managing bee diseases amid declining populations.
