FIGURE 4 | Linear regression plots of the relationship between genetic diversity (mean number of pairwise differences π) and physical characteristics of paleodrainage (contemporary land area, continental shelf area exposed and number of contemporary basins) as described by Thomaz, Knowles, 2018 (S2). A. Contemporary land area (R2 = 0.90); B. Continental shelf area exposed (R2 0.77); C. Number of contemporary basin (R2 = 0.21).
