Intensity index of pastoral activities reconstructed from Lake Verney sediments, over the last 4600 years

Method used to calculate the index: This index has been calculated on the basis of pastoral indicators obtained from the DNA metabarcoding approach targeting plants (ruderal/nitrophilous taxa associated with pastoralism) and mammals (for domesticated animals). The selected pastoral indicators, here, are Plantago sp. and Rumex sp. for plants, and Bos and Ovis for mammals. They are standardized by calculating a z-score. Then, the index is calculated as the average of all these standardized indicators. […]
