Fig. 4 in Flowing into the unknown: inferred paleodrainages for studying the ichthyofauna of Brazilian coastal rivers

Fig. 4. Results of correlation tests: a. between the paleodrainage total area with contemporary land area encompassed by each paleodrainage (r2 = 0.99; P <0.0001); b. the number of contemporary basins encompassed by each paleodrainage (r2 = 0.17; P <0.0001); and c. between the contemporary land area and the area of the continental shelf exposed during the drop in sea level (r2 = 0.04; P = 0.01). Individual values per paleodrainages are given in Tab. 1.
