Table 3.

Differences in mean number of bony fish MOTUs per sample amplified with a 12S primer pair and identified at different taxonomic levels between Crangon crangon pooled stomach and sediment samples. Higher taxonomic ranks include MOTUs identified at the lower levels. See Supporting Information Table S3 for rarefied data
