  abstract = {{B}ackground and aims - {T}he isolation of populations inside forest refugia during past climate changes has widely been hypothesized as a major driver of tropical plant diversity. {E}nvironmental conditions can also influence patterns of diversity by driving divergent selection leading to local adaptation and, potentially, ecological speciation. {G}enetic and phylogenetic approaches are frequently used to study the diversification of {A}frican tree clades. {H}owever, the environmental space occupied by closely related species or intra-specific gene pools is barely quantified, though needed to properly test hypotheses on diversification processes. {M}ethods - {U}sing species distribution models, we determined the bioclimatic constraints on the distribution of closely related species and intra-specific gene pools. {O}ur study model, {E}rythrophleum ({F}abaceae - {C}aesalpinioideae), is a tropical tree genus widespread across {A}frica, and vastly investigated for genetics. {H}ere, we combined the available phylogenetic data with information on niche divergence to explore the role of ecology into diversification at the species and gene pool levels. {K}ey results - {E}cological speciation through climate has probably played a key role in the evolution of the {E}rythrophleum species. {T}he differential climatic niche of the species indicated adaptive divergence along rainfall gradients, that have probably been boosted by past climate fluctuations. {A}t the gene pool level, past climate changes during the {P}leistocene have shaped genetic diversity, though within {E}rythrophleum suaveolens, adaptive divergence also occurred. {C}onclusions - {W}e believe that ecological speciation is a key mechanism of diversification for tropical {A}frican tree species, since such climatic niche partition exist among many other genera. {M}odelling the environmental niche of closely related taxa, and testing for niche differentiation, combined with divergence dates offered new insights on the process of diversification.},
