ALT (a) Genogeographic species clustering dendrogram based on the genetic diversity measure H, clustering together those species with similar spatial patterns. Cluster number is marked on each branch. Clusters predominantly joined at the 10% significance level are marked with (*). (b) Scaled-and-centred genogeographic curves within selected clusters. (c) Average colour maps of selected clusters

ALT (a) Ecklonia radiata forest and associated community. The white square highlights the kelp holdfast, which was used as the focal sampling unit in our study. (b) Overview of the experimental design to investigate the impact of alternative decisions and procedures on biodiversity estimates for kelp holdfast assemblages using community DNA metabarcoding.
