  abstract = {{A} phylogeographic study was conducted on the {N}ile grass rat, {A}rvicanthis niloticus, a rodent species that is tightly associated with open grasslands from the {S}udano-{S}ahelian regions. {U}sing one mitochondrial (cytochrome b) and one nuclear (intron 7 of {B}eta {F}ibrinogen) gene, robust patterns were retrieved that clearly show that (i) the species originated in {E}ast {A}frica concomitantly with expanding grasslands some 2 {M}a, and (ii) four parapatric and genetically well-defined lineages differentiated essentially from {E}ast to {W}est following {P}leistocene bioclimatic cycles. {T}his strongly points towards allopatric genetic divergence within savannah refuges during humid episodes, then dispersal during arid ones; secondary contact zones would have then stabilized around geographic barriers, namely, {N}iger {R}iver and {L}ake {C}had basins. {O}ur results pertinently add to those obtained for several other {A}frican rodent as well as non-rodent species that inhabit forests, humid zones, savannahs and deserts, all studies that now allow one to depict a more comprehensive picture of the {P}leistocene history of the continent south of the {S}ahara. {I}n particular, although their precise location remains to be determined, at least three {P}leistocene refuges are identified within the {W}est and {C}entral {A}frican savannah biome.},
