Editorial overview : global change biology : which little things will run the world in the future?

This special issue on global change biology features four exciting and contemporary articles addressing how different aspects of global change might affect insects. The four articles focus on landscape changes (Vanbergen; Goldson et al.) and changes to our atmosphere and climate (Ode et al.; Facey et al.). Vanbergen discusses how landscape modification is likely to affect pollinators, specifically focussing on how this can disrupt intra-specific and inter-specific pollinator behavioural interactions. Goldson and colleagues examine issues for another ecosystem service provided by insects "” biological control. Ode and colleagues looks at how atmospheric change, and specifically increases in the concentrations of greenhouse gases (carbon dioxide, CO2 and ozone, O3) might affect insect herbivores and higher trophic groups by altering plants at the chemical level. Facey and colleagues consider how e[CO2] and elevated air temperatures shape herbivore-enemy interactions.
