Median unweighted UniFrac distances between three dolphin habitats: Shedd, MMP, and Sarasota. Median unweighted UniFrac distances between three dolphin habitats: Shedd, MMP, and Sarasota. The rows and columns have been grouped with hierarchical clustering to present more similar patterns next to each other. Darker blue squares represent higher similarities between samples. Gray squares represent comparisons with less than the minimum 100 UniFrac distances to confidently compute the statistics. Cesar Cardona et al. mSystems 2018; doi:10.1128/mSystems.00052-18
