Introduction
This auxiliary material consists of three tables containing the full elemental and amino acid
composition of the peat cores, bog-forming vegetation, and microbes analyzed. Methods for
amino acid analysis can be found in the text of the manuscript. Table S1 contains amino acid
composition and yields of the four cores, and Table S2 contains the composition and yields of
the source materials.
