  abstract = {{T}he multimammate rat {M}astomys huberti is a {S}ahelian species restricted to {W}est {A}frica. {T}hroughout its distribution area, the species is associated with humid habitats, flood plains and ponds, which make its current distribution highly fragmented. {K}nowing that humid and dry climatic phases regularly alternated along the {Q}uaternary in {W}est {A}frica, it can be postulated that the evolutionary history of the species and its genetic variation largely reflect these climatic oscillations. {W}e used mitochondrial cytochrome b sequences to investigate the phylogenetic relationships of {M}. huberti populations across the totality of the species' geographical range ({M}ali, {S}enegal, {G}uinea and {M}auritania). {W}e found that cytochrome b sequence variation is partitioned into four divergent clades (mean {K}imura 2-parameter genetic distances varying from 0.57 to 3.08%) corresponding to distinct geographical regions. {W}e dated the separation events of these clades between 0.93 and 0.17 million years ago, suggesting that {M}. huberti history was strongly influenced by the {Q}uaternary climatic variations and related hydrographic network changes. {R}elationships between lineages and the partitioning of genetic diversity suggest the occurrence of two refuges along the {A}tlantic coast during arid periods. {M}oreover, the species' current range results from a stepwise colonization from west to east. {M}. huberti colonized recently the {I}nner {D}elta of {N}iger {R}iver in {M}ali, probably during a humid episode some 0.6 million years ago. {D}emographically stable and highly diversified populations were found in {S}outh {S}enegal and {G}uinea while populations in {N}orth {S}enegal and in {M}ali experienced low numbers followed by a demographic expansion during the {A}frican {H}umid {P}eriod (c. 14 800-5500 {BP}). {D}uring the last arid period (c. 23 000-18 000 years ago), {M}alian populations found refuge in the northern parts of the {I}nner {D}elta of the {N}iger {R}iver, then expended to the southern parts of the delta and along the course of the {N}iger {R}iver downstream {T}ombouctou. {M}ore recently, {M}. huberti would have rapidly expanded into irrigated areas along the {S}enegal {R}iver and along the {C}anal du {S}ahel, {M}ali, reflecting the invasive and the pest character of this species.},
