Assessing Pollinator Resilience to Environmental Warming through Novel Technologies

Bee decline threatens ecosystem sustainability through reductions in pollination services to plants and crops. The reliance on bee pollination for food security and ecosystem functioning has emphasized the critical need to understand resilience of wild bee populations in response to environmental stressors. Increased variation in environmental temperature due to climate change is a key stressor to bees and potential driver of pollinator decline generally. However, it remains unclear what the physiological consequences of environmental warming for wild bees are and how increasing temperature interacts with other stressors (e.g., pathogen dynamics) to impact population stability. Here, we propose to address these questions through a new collaborating team involving Entomologists and Engineers to develop technologies that facilitate the study of the impact of environmental warming on wild bee pollinators. We propose to (1) investigate how microclimatic temperature variations impact thermal tolerance in wild bees, (2) develop and manufacture devices for field-based thermal tolerance assays of wild-caught bees, and (3) train students in interdisciplinary research involving biology, physics, and engineering. Anticipated results from this project include data for future proposals that seek external funding to study questions about the resilience of wild pollinators to climate change and associated interactions with other stressors.
