Salt concentrations in plant tissues. from Multiple riparian–stream connections are predicted to change in response to salinization

Sodium concentation in leaf species across the globe presented by geographic location. Fold change was calculated based on mean Na leaf concentrations from plants in salty (>100km from coast or salted road or experimental salt addition treatments) divided by non-salty (<100 km or controls) plant Na leaf concentrations (reversed for negative values). Values of 1 indicate no change. Positive values indicate plants in saltier areas had increased Na leaf content relative to non-salty areas. Negative values indicate plants in saltier areas had decreased Na leaf content relative to non-salty areas. Family mean values between -1 and 1 indicate no consistent trend. Fold-change is salt-rich dividided by salt-scarce and presented in figure 2.
