Principal coordinate ordinations for the (a) Reef Life visual fish survey data, (b) fish detected in eDNA with COI primers, and (c) all metazoans detected in eDNA with COI primers. Percentages in the axis titles represent the proportion of that axis’ eigenvalue to the sum of all eigenvalues. Clupeid and Belonid abundances were omitted from (a) due to their poor taxonomic resolution and high abundance (10⁴–10⁶) estimations by divers on a single transect, making them clear outliers in the ordinations.
