PCA of the PLFA pattern of peat samples incubated at different temperatures. Gj, Gjødalsmosan; Kil, Killingmo; Kom, Komnes; Gr, Greninmosan. Bold abbrevations indicate peat incubated at 25°C for 3 days, 55 indicates peat incubated at 55°C for 3 days, and 25 indicates peat incubated at 55°C for 3 days followed by incubation at 25°C for 80 days (Gj 1 and Kil 2), 30 days (Kom 2), or 50 days (Gr 3). (A) Score plot of the different peat samples. (B) Loading plot of the individual PLFAs. The PLFAs T1, T2, and 18:1ω7-T3 are in bold.
