Presentation description

As climate change disrupts ecosystems, the timing of pollinator emergence and plant flowering may become mismatched. The Blue Orchard Mason Bee (Osmia lignaria) uses diapause to regulate winter dormancy and emergence based on environmental cues, while many plants rely on photoperiod to bloom. We delayed bee emergence and tracked foraging and nesting using pollen metabarcoding. Results suggest late-emerging bees forage differently, which may affect pollination and plant reproduction.
