Taxon-specific niche separation identified through principal component analysis (PCA) of bulk carbon (δ13Cbulk) and nitrogen (δ15Nbulk) isotopes and CSIA-based parameters including δ15N of metazoan (TPmet) and protistan (TPprot) trophic positions, baseline δ15N (δ15NPhe) and microbial resynthesis (∑V). The two axes explain 86.1 % of the variance within the dataset.
