Fig. 6From: Integration of spatio-temporal variations of surface metabolomes and epibacterial communities highlights the importance of copper stress as a major factor shaping host-microbiota interactions within a Mediterranean seaweed holobiontSpatiotemporal correlation network (multi-block sPLS-DA, DIABLO analysis) of the surface metabolome, epibacterial community, and environmental variables. Using a sparse method, the network was constructed with an optimal number of variables according to the tuning procedure, which corresponded to a total of 32 metabolites, 37 OTUs, and 2 environmental parameters with only positive correlations above 0.7 and negative correlations below −0.7Back to article page
