The decline of pollinators is a major concern for sustainable agriculture and biodiversity. The interactive effects of sublethal agrochemicals is a particularly pressing problem as we generally have lacked accepted experimental approaches for evaluating risk. Our symposium is organized to bring together researchers working on these questions at a range of levels of biological organization, as well as to link university researchers with representatives of government and agricultural industries. All presentations are pre-recorded, but there will be an online video chat/panel discussion on Friday Nov 20 and Monday Nov 23 at 11 AM Eastern Standard time.
