Figure 4

Illustration of the polynomial regression curve of order 3 (polyn regr; grey line) of Fij residuals on the logarithm of distance. Observed Fij values are on average higher than their expectation from linear regression (Fij exp) at short distance in this population. This results in a concave polynomial regression line at short distance (at the first distance class), indicating that seed dispersal is restricted compared to pollen dispersal. A convex shape would indicate restricted pollen dispersal (see also text and Table 4).
