Fig. 6: Constrained ordination of MAG-based microbial community composition reveals latitudinal heterogeneity driven by water quality.
From: A genome-centric view of the role of the Acropora kenti microbiome in coral health and resilience
Dissimilarity between seawater and A. kenti community composition based on the Hellinger-transformed Bray-Curtis distance metric of overall dereplicated MAGs (n = 112), analysed using principal coordinates analysis with the Island site of origin of samples (n = 28) as a factor (a), and water quality categories of samples (n = 22) as a factor (b). Model significance was tested using one-way analysis of variance. Significant water quality parameters contributing to A. kenti community dissimilarity were identified using factor fitting to an ordination (c), and the structuring nature of the strongest correlates across the water quality categories was visualised using constrained ordination (d). In (b−d), the ordinations and significance tests were performed on A. kenti-specific MAGs (n = 63) and samples (n = 22) only. Model outputs are provided in Supplementary Data 5−8. POC particulate organic carbon; TDN total dissolved nitrogen. P values were corrected for multiple testing made by controlling the False Discovery Rate.
