Hierarchical clustering of samples using the Jaccard index. Using shared OTU profiles across all samples, we computed Jaccard indices for clustering samples based on overall community similarity. Samples from each water environment cluster well, but even using OTU resolution, the fruit surface samples were not easily distinguishable.
