Table S1 Analysis and physiological characteristics (pathway types) of modern pollen species: carbon and nitrogen weight content, δ13C, δ15N and C : N ratio
Fig. S1 The results of the bivariate quadratic discriminant analysis (QDA) for C : N ratio and δ13C applied to the three functional groups: herbaceous including Poaceae, deciduous trees, and evergreen trees. The plots show the bivariate posterior probability for each group.
Fig. S2 Fourier transform infrared (FTIR) for Sorghum (a) and Platanus (b), and 13C-CP/MAS NMR (cross-polarization and magic-angle spinning nuclear magnetic resonance) data for Sorghum (c) and Platanus (d), for untreated pollen (lower curves), acetolysis (middle curves), and H2SO4 (upper curves) treatments.
