Figure 4

Stable isotope values of each analysed sample. δ13C on the X-axis and δ15N on the Y-axis, both in ‰. Each taxon is coloured with a unique colour, and higher taxon groups are indicated by the shape of the point. The two distinct clusters of Mohnia mohni (Cluster A and B) are enclosed in ellipses. Isotopic signatures of photosynthesis-derived POM from sediment (sPOM) and pelagic samples (pPOM) from the literature are indicated by open squares. The assumed isotopic enrichment per trophic level of microbial feeders (microb) and invertebrate feeders (invert) is indicated with arrows.
