  abstract = {{P}ollen and seed dispersal are key processes affecting the demographic and evolutionary dynamics of plant species and are also important considerations for the sustainable management of timber trees. {T}hrough direct and indirect genetic analyses, we studied the mating system and the extent of pollen and seed dispersal in an economically important timber species, {E}ntandrophragma cylindricum ({M}eliaceae). {W}e genotyped adult trees, seeds and saplings from a 400-ha study plot in a natural forest from {E}ast {C}ameroon using eight nuclear microsatellite markers. {T}he species is mainly outcrossed (t=0.92), but seeds from the same fruit are often pollinated by the same father (correlated paternity, r(p)=0.77). {A}n average of 4.76 effective pollen donors ({N}-ep) per seed tree contributes to the pollination. {S}eed dispersal was as extensive as pollen dispersal, with a mean dispersal distance in the study plot approaching 600m, and immigration rates from outside the plot to the central part of the plot reaching 40% for both pollen and seeds. {E}xtensive pollen- and seed-mediated gene flow is further supported by the weak, fine-scale spatial genetic structure ({S}p statistic=0.0058), corresponding to historical gene dispersal distances (sigma(g)) reaching approximately 1,500m. {U}sing an original approach, we showed that the relatedness between mating individuals ({F}-ij=0.06) was higher than expected by chance, given the extent of pollen dispersal distances (expected {F}-ij=0.02 according to simulations). {T}his remarkable pattern of assortative mating could be a phenomenon of potentially consequential evolutionary and management significance that deserves to be studied in other plant populations.},
