  abstract = {{P}hylogeographic studies on widespread rainforest species from {W}est and {C}entral {A}frica often reveal genetic discontinuities. {T}hese discontinuities can originate from past barriers to gene flow resulting from long-lasting population fragmentation during glacial periods, according to the forest refuge hypothesis. {T}his study 69 nuclear {SNP}s, 13 plastid {SNP}s, and 24 mitochondrial {SNP}s to characterized the distribution of genetic diversity in 377 individuals of the widespread tropical tree {K}haya ivorensis, in western and central {A}frican evergreen forests. {T}wo very well-differentiated nuclear genetic clusters ({F}-{ST} = 0.28) are located respectively in {W}est and {C}entral {A}frica. {T}he gradual transition of allele frequencies between the clusters across a broad geographic area going from {C}ameroon to {N}igeria accords with the recognition of a single species, although we show an incipient divergence that could eventually lead to the separation of two taxa. {T}he two clusters have similar genetic diversity at nuclear {SNP}s. {H}owever, the cytoplasmic data revealed high haplotypic diversity and numerous endemic haplotypes in {C}entral {A}frica, and only one widespread haplotype in {W}est {A}frica, suggesting an ancient colonization of {W}est {A}frica from {C}entral {A}frica. {T}he genetic diversity inside and outside putative forest refugia ({A}nhuf et al., {P}alaeogeogr {P}alaeoclimatol {P}alaeoecol 239:510-527, 2006) does not differ significantly in either genetic cluster. {H}ence, we cannot confirm that forest refugia played a particular role in the pattern of distribution of genetic diversity in {K}. ivorensis. {O}wing to the high haplotypic diversity of their populations, {C}entral {A}frica, especially {G}abon, constitutes a priority area for the conservation of the genetic diversity of {K}. ivorensis.},
