  abstract = {{A}im {T}o describe the phylogeographic patterns of the black rat, {R}attus rattus, from islands in the western {I}ndian {O}cean where the species has been introduced ({M}adagascar and the neighbouring islands of {R}eunion, {M}ayotte and {G}rande {C}omore), in comparison with the postulated source area ({I}ndia). {L}ocation {W}estern {I}ndian {O}cean: {I}ndia, {A}rabian {P}eninsula, {E}ast {A}frica and the islands of {M}adagascar, {R}eunion, {G}rande {C}omore and {M}ayotte. {M}ethods {M}itochondrial {DNA} (cytochrome b, t{RNA} and {D}-loop, 1762 bp) was sequenced for 71 individuals from 11 countries in the western {I}ndian {O}cean. {A} partial {D}-loop (419 bp) was also sequenced for eight populations from {M}adagascar (97 individuals), which were analysed in addition to six previously published populations from southern {M}adagascar. {R}esults {H}aplotypes from {I}ndia and the {A}rabian {P}eninsula occupied a basal position in the phylogenetic tree, whereas those from islands were distributed in different monophyletic clusters: {M}adagascar grouped with {M}ayotte, while {R}eunion and {G}rand {C}omore were present in two other separate groups. {T}he only exception was one individual from {M}adagascar (out of 190) carrying a haplotype that clustered with those from {R}eunion and {S}outh {A}frica. '{I}solation with migration' simulations favoured a model with no recurrent migration between {O}man and {M}adagascar. {M}ismatch distribution analyses dated the expansion of {M}alagasy populations on a time-scale compatible with human colonization history. {H}igher haplotype diversity and older expansion times were found on the east coast of {M}adagascar compared with the central highlands. {M}ain conclusions {P}hylogeographic patterns supported the hypothesis of human-mediated colonization of {R}. rattus from source populations in either the native area ({I}ndia) or anciently colonized regions (the {A}rabian {P}eninsula) to islands of the western {I}ndian {O}cean. {D}espite their proximity, each island has a distinct colonization history. {I}ndependent colonization events may have occurred simultaneously in {M}adagascar and {G}rande {C}omore, whereas {M}ayotte would have been colonized from {M}adagascar. {R}eunion was colonized independently, presumably from {E}urope. {M}alagasy populations may have originated from a single successful colonization event, followed by rapid expansion, first in coastal zones and then in the central highlands. {T}he congruence of the observed phylogeographic pattern with human colonization events and pathways supports the potential relevance of the black rat in tracing human history.},
