  abstract = {{T}he natural regeneration of tree species depends on seed and pollen dispersal. {T}o assess whether limited dispersal could be critical for the sustainability of selective logging practices, we performed parentage analyses in two {C}entral {A}frican legume canopy species displaying contrasted floral and fruit traits: {D}istemonanthus benthamianus and {E}rythrophleum suaveolens. {W}e also developed new tools linking forward dispersal kernels with backward migration rates to better characterize long-distance dispersal. {M}uch longer pollen dispersal in {D}. benthamianus (mean distance d(p) = 700 m, m(p) = 52% immigration rate in 6 km(2) plot, s = 7% selfing rate) than in {E}. suaveolens (d(p) = 294 m, m(p) = 22% in 2 km(2) plot, s = 20%) might reflect different insect pollinators. {A}t a local scale, secondary seed dispersal by vertebrates led to larger seed dispersal distances in the barochorous {E}. suaveolens (d(s) = 175 m) than in the wind-dispersed {D}. benthamianus (d(s) = 71 m). {Y}et, seed dispersal appeared much more fat-tailed in the latter species (15%-25% seeds dispersing >500 m), putatively due to storm winds (papery pods). {T}he reproductive success was correlated to trunk diameter in {E}. suaveolens and crown dominance in {D}. benthamianus. {C}ontrary to {D}. benthamianus, {E}. suaveolens underwent significant assortative mating, increasing further the already high inbreeding of its juveniles due to selfing, which seems offset by strong inbreeding depression. {T}o achieve sustainable exploitation, seed and pollen dispersal distances did not appear limiting, but the natural regeneration of {E}. suaveolens might become insufficient if all trees above the minimum legal cutting diameter were exploited. {T}his highlights the importance of assessing the diameter structure of reproductive trees for logged species.},
