Data for the relative distribution in bulk TOC, n-alkane and n-alkanoic acids across particle size fraction and bulk soil of terrestrial ecosystem

The Supplementary Materials contains: Table S1, which tabulates the relative distribution of n-alkane homologues across soils and separated fractions collected across forest, grassland and mixed ecosystems Table S2, which tabulates the relative distribution of n-alkanoic acids homologs across soils and separated fractions collected across forest, grassland and mixed ecosystems. Table S3, tablulates the particle size fraction seperated from bulk soil and the associated organic content across forest, grassland and mixed ecosystems. Table S4, tabulates the abundance of n-alkane concentration and the measured indices and their variability across soils, roots and separated fractions collected across different ecosystems. Table S5, tabulates the abundance of n-alkanoic acids concentration and the measured indices and their variability across soils, roots and separated fractions collected across different ecosystems.
