Only the Iceman´s intestine samples (red square) are displayed, all other samples are left out to avoid overcrowding. The first three axes of the PCA accounted 80.8% of the variance in the species data (axis1: 70.1%, axis2: 6.4% and axis3: 4.3%). The few names in red are those mosses recovered from the Iceman’s alimentary tract.
