Rank abundance distribution of unique protistan OTUs. Protistan (including fungi) rank abundance distribution of unique operational taxonomic units (OTUs) obtained from four samples of the Caribbean Cariaco Basin (CAR1-4) and from four samples of the Norwegian Framvaren Fjord (FV1-4). For sampling sites information see Table 1. Curves were obtained when clustering tags at zero differences as described in pipeline 2 of the sequence data processing paragraph in the methods section. Subsequently tags were ordered according to decreasing rank (number of replicates present for each tag).
