  1. Only one ramet per genotype was included for the analysis; 163 in population A and 83 in population B resulting in an actual density of adults (D) of 0.0008578 trees per m2 in population A and 0.0008300 trees per m2 in population B. Gene dispersal was then estimated at four effective densities (De) estimated from the actual density (D). An asterisk indicates that the estimation procedure did not reach convergence at the effective density being tested. Nb values presented are based on the assumed De of D/2.
