From: Future large hydropower dams impact global freshwater megafauna
Relative change in freshwater megafauna distribution range affected by hydropower dams in the future compared to distribution range affected by existing dams on a sub-catchment scale (compare Fig. 1 for latitudinal scale). Please note: The y-axis is given in log scale; there are no existing dams but future hydropower dams in sub-catchments with a number of 19, 20 or 22 megafauna species (light grey columns), thus, mathematically the relative change cannot be calculated but converges to infinity. Absolute values for distribution range fractions affected by existing dams and future hydropower dams can be found in Fig. S3.
