Web20. sep 2024 · The changes in the salinity of the TRP soils appear to be an important factor affecting the MBT’ 5ME and the relative abundance of 6- vs. 5-methyl pentamethylated brGDGTs (IR IIa’). This is likely to introduce certain scatters in the correlations between MBT’ 5ME and MAAT and that between IR IIa’ and pH determined at the global scale.
