Overall, the JSD distance of Donor A x to the outcome community showed a negative trend over time (e.g. negative slopes), representing a progressive increase in the contribution of this donor community over the sampling period ( P < .001), except for A −5 with no correlation between JSD distance of Donor A −5 —outcome community and time ( P > .05).
In contrast, Donor B x showed a positive trend in JSD distances over time, representing a temporal decrease in the contribution of this donor in the treatment sets AxB x ( P < .001).
treatment AxB −1 ), no significant correlation was observed between shifts in community structure and metabolic profile, and a marginally significant negative correlation was found between shifts in community structure and enzymatic activities.
