ALT The hypothesis illustrating how the relationship between mean taxon size and abundance affects community functions under warming and eutrophication scenarios (community functions are calculated as the sum of all individual taxa performances). (A) Climate warming is expected to increase the abundance of small taxa and decrease the abundance of large ones, as indicated by a steeper slope compared with baseline conditions (dash line). (B) Eutrophication would increase large taxa and decrease small ones, as indicated by a flatter slope compared with baseline conditions (dash line). The different responses emerging across taxa will create a compensatory effect on community functions, as indicated by the total shaded area.

ALT Effect of pollinator floral fidelity, averaged across all Bombus observed during the represented study period. Manipulation is plotted in the “high” bin if half or more of the overall Bombus community was removed and in the “low” bin if less than half was removed

ALT The number of species based on the quantification of functional importance. Stacked graphs of (a) herbaceous plants (experimental communities), (b) herbaceous plants, and (c) soil fungi (natural communities) show the number of species that are associated with significantly higher and lower multifunctionality than the null expectation. All possible combinations of multiple functions (scenarios) were considered
