Resumo
Human driven environmental changes increase the concentrations of polluting reactive compounds in the
troposphere, such as ozone and nitrogen oxides. These changes lead to biodiversity losses and alter plant
physiology and plant-pollinator interactions, essential for pollination services, with potential consequences for
agricultural production. Here we used 133 unique sampling events from NW Europe to investigate how air
pollution (ozone and nitrogen oxides) and other sources of nitrogen is related to pollinator visitation rate and
their contribution to agricultural production, also considering possible interactive effects with landscape quality
and pesticide input. We showed that ozone modulates the effect of pesticide exposure and temperature on crop
pollinators, increasing the probability of negative impacts on crop pollination. Indeed, when ozone levels are
highest, the strength of the effect of pesticide on pollinators is more than double then when ozone levels are
intermediate. This indicates that air pollution should be considered in management plans and policies aiming to
safeguard biodiversity and promote more sustainable food production practices
