Species interactions have a spatiotemporal component driven by environmental cues, which if altered by climate change can drive shifts in community dynamics. There is insufficient understanding of the precise time windows during which inter‐annual variation in weather drives phenological shifts and the consequences for mismatches between interacting species and resultant population dynamics—particularly for insects. We use a 2...

In future elevated CO 2 environments, chewing insects are likely to perform less well than at present because of the effects of increased carbon fixation on their host plants. When the aphid, Aulacorthum solani was reared on bean ( Vicia faba ) and tansy ( Tanacetum vulgare ) plants under ambient and elevated CO 2, performance was enhanced on both hosts at elevated CO 2 . The nature of the response was different on each plant...
