Zusammenfassung: | Artificial reefs (ARs) are often used to restore and develop seaweed beds. However, few studies have reported the changes of biological community on the substrate surface before and after the attaching substrates were transferred. In this study, the response of the biological community, including macrobiotic biofouling and microbial community, to translocation of seaweed attaching substrate were investigated. The results showed that the seaweed coverage ratio significantly reduced after the translocation, the macrobiotic biofouling community diversity on attaching substrates increased after the translocation, and the transplanted substrates had more percentage cover and lower biodiversity than the untransplanted substrates. In addition, highest diversity was found on microbial community after the translocation. Non-metric multidimensional scaling (NMDS) revealed that the microbial community on the transfered substrates was significantly different from that before and without transfer. Co-occurrence network analysis showed that the degree of bacterial community network connection was highest before the translocation. The result revealed that the translocation of seaweed substrate could affect the biological community composition, and could accelerate the changes in macrobiotic biofouling community on the back of substrates.
•The response of the biological community to the transplantation of seaweed attaching substrate was studied.•The algae coverage ratio significantly reduced after the transplantation.•The macrobiotic biofouling community diversity on attaching substrates increased after transplantation.•The microbial community on the transfered substrates was significantly different from that before and without transfer.•The degree of bacterial community network connection was highest before transplantation. |
