Pollination is an essential process in the sexual repro- duction of seed plants and a key ecosystem service to human welfare. Animal pollinators decline as a conse- quence of five major global change pressures: climate change, landscape alteration, agricultural intensifica- tion, non-native species, and spread of pathogens. These pressures, which differ in their biotic or abiotic nature and their spatiotemporal scales, can interact in nonad- ditive ways (synergistically or antagonistically), but are rarely considered together in studies of pollinator and/or pollination decline. Management actions aimed at buff- ering the impacts of a particular pressure could thereby prove ineffective if another pressure is present. Here, we focus on empirical evidence of the combined effects of global change pressures on pollination, highlighting gaps in current knowledge and future research needs.
