DescriptionOngoing agricultural intensification and landscape simplification negatively impact wild pollinators and the pollination service they provide to both crops and wild plants. As a result, there is currently a strong focus on how to benefit pollinator populations in agricultural landscapes, by e.g. preserving semi-natural habitats or providing supplemental flower resources in the form of flower strips. However, not all pollinators are the same, neither in terms of how they react to landscape change and mitigation measures, nor in what services they provide. Using recent research in our group, we demonstrate the implication for pollinators and pollination. Combining modelling and empirical field studies, we demonstrate (i) how spatio-temporal availability of food and nesting resources act as spatial ecological filter for bees, (ii) the scales at which mitigation of loss of flower resources affect pollinators, (iii) how competitive interactions modify the responses of individual species, and (iv) how this may explain how wild flower pollinated by generalist and specialist pollinators, respectively, are differentially affected by contemporary landscape simplification. We discuss our results in relation to where and when pollinator mitigation measures should be implemented to preserve pollination as a service.
