  abstract = {{T}he fine-scale genetic structure and how it varies between generations depends on the spatial scale of gene dispersal and other fundamental aspects of species' biology, such as the mating system. {S}uch knowledge is crucial for the design of genetic conservation strategies. {T}his is particularly relevant for species that are increasingly fragmented such as {B}oswellia papyrifera. {T}his species occurs in dry tropical forests from {E}thiopia, {E}ritrea and {S}udan and is an important source of frankincense, a highly valued aromatic resin obtained from the bark of the tree. {T}his study assessed the genetic diversity and fine-scale spatial genetic structure ({FSGS}) of two cohorts (adults and seedlings) from two populations ({G}uba-{A}renja and {K}urmuk) in {W}estern {E}thiopia and inferred intra-population gene dispersal in the species, using microsatellite markers. {T}he expected heterozygosity ({H} {E}) was 0.664–0.724. {T}he spatial analyses based on kinship coefficient ({F} ij) revealed a significant positive genetic correlation up to a distance of 130 m. {S}patial genetic structure was relatively weak ({S}p = 0.002–0.014) indicating that gene dispersal is extensive within the populations. {B}ased on the {FSGS} patterns found, we estimate indirectly gene dispersal distances of 103 and 124 m for the two populations studied. {T}he high heterozygosity, the low fixation index and the low {S}p values found in this study are consistent with outcrossing as the (predominant) mating system in {B}. papyrifera. {W}e suggest that seed collection for ex situ conservation and reforestation programmes of {B}. papyrifera should use trees separated by distances of at least 100 m but preferably 150 m to limit genetic relatedness among seeds from different trees.},
