Table 2.
Similarity percentage analysis to identify protist groups that best differentiated sites with mesotrophic and eutrophic trophic states during 5–10 October 2019, along the New River, Belize. Contribution percentage for each group and cumulative percentage (up to 70%) are shown. Average relative abundance of protist groups is shown for mesotrophic and eutrophic sites. Groups with significant contributions to dissimilarities are in bold.
