Histograms of (A) dxylem and (B) dxylem_c binned following the biome classification in ref. 2. The dashed red line (precipitation offset = zero) serves as reference for quantifying the offset of environmental waters from local precipitation. Here, only precipitation offsets of xylem are shown comparing the original (dxylem) and recalculated (dxylem_c) values.
