Fig. 4: The influence of climate parameters on isotope separation.
From: The extent to which soil hydraulics can explain ecohydrological separation
The effect across model simulations of varying the total input precipitation on the average δ2H difference between drainage and a mobile or b immobile soil water as well as the influence of varying the amount effect’s negative correlation represented by the Pearson correlation coefficient, ρ, between precipitation amount, P, and its δ2H composition on the average δ2H difference between drainage and c mobile or d immobile soil water. Precipitation is shown as a percent of the baseline amount (=101.5 cm). Differences are show as boxplots for models with high and low immobile fractions (Hf and Lf) and transfer rates (Hω and Lω) as well as for a single porosity column (0f). Each boxplot represents flux and volumetrically weighted averaged differences, with the box spanning upper and lower quartiles, whiskers extending 1.5 times the interquartile range, diamonds as outliers, and black triangles indicating the mean calculated from 10 simulations.
