The abundance of prokaryotes was determined after SYBR Green staining, whereas the abundances of different taxonomic groups were determined via CARD-FISH. Means with SD are given (n = 4). The asterisks indicate significant differences between dry sediment from day 0 used for rewetting and the treatment samples (ANOVA, * = P<0.05, ** = P<0.01).
