Parameters estimated by quadratic models to examine the regressions of the correlated paternity of pollen pools between seed-parent pairs against the spatial distances between the seed-parent pairs in the two reproductive years

Parameters	Estimate	Stndard error	t statistic

a	5.917 E−2	9.805 E−3	6.035***
b	−3.150 E−4	4.217 E−5	−7.469***

Equation of the model: C_p = a + bD + cD², where C_p is correlated paternity and D is spatial distance between seed-parent pairs. E^x means 10^x
