Average ¹³C tracer incorporation in marker fatty acids for arbuscular mycorrhiza fungi (AM fungi), saprotrophic fungi (Sapro. fungi), Gram‐negative bacteria (Gram(−)), Gram‐positive bacteria (Gram(+)) and actinobacteria (Actinobact.), extracted from soil cores from 0 to 7 cm depth of control (closed symbols) and drought (open symbols) monoliths from the abandoned grassland (circles) and the meadow (squares); after the resistance (a) and the resilience (b) ¹³C pulse labelling. Dotted lines separate amongst the five different microbial groups. Error bars show ± SE (n = 3); inc. ¹³C, incorporated ¹³C
