Abstract | Common pollutants of the troposphere, such as diesel exhaust (including nitrogen oxides - NOx) and ozone (O3), are known to react in the gas phase with some of the most ubiquitous volatile organic compounds (VOCs) emitted by flowers. This has potentially deleterious implications for the insects that use these VOCs for location and recognition of floral resources. As such, a limited number of behavioral studies have demonstrated that these pollutants may reduce pollinator foraging efficiency. To-date these studies have focused on a narrow range of pollinator species and there has been limited field-scale validation. Here we present results from a field-based assessment of the impacts of elevated diesel exhaust pollution and ozone on insect pollination services. Using a unique Free Air Diesel and Ozone Exposure (FADOE) ring facility, which emits regulated quantities of diesel exhaust and ozone, alone and in combination, from a series of 8m diameter rings, we measured metrics of pollination services on flowering Brassica nigra plants placed within the rings. Both pollutants had clear effects on insect pollinators, with significant reductions in pollinator counts and flower visits, which coincided with decreases in yield metrics of our study plant. These results support the findings of previous laboratorybased behavioral assays, providing evidence of significant negative field-scale effects of air pollution on insect-derived pollination services. |
