Correlations between genetic diversity parameters (A_R, H_e, and F_i) and latitude. The analysis was performed for hexaploid E. arundinaceus (orange), tetraploid E. arundinaceus (blue), and E. procerus (yellow). Latitudes were rounded to integers. Significant correlations are indicated (*p < 0.01 and ***p < 0.0001)
