  abstract = {{E}cological interactions are an important source of rapid evolutionary change and thus may generate a significant portion of novel biodiversity. {S}uch changes may be particularly prevalent in parasites, where hosts can induce strong selection for adaptation. {T}o understand the relative frequency at which host-associated divergences occur, it is essential to examine the evolutionary history of the divergence process, particularly when it is occurring over large geographical scales where both geographical and host-associated isolation may playa part. {I}n this study, we use population genetics and phylogeography to study the evolutionary history of host-associated divergence in the seabird tick {I}xodes uriae ({A}cari, {I}xodidae). {W}e compare results from microsatellite markers that reflect more ecological timescales with a conserved mitochondrial gene ({COIII}) that reflects more ancient divergence events. {P}opulation structure based on microsatellites showed clear evidence of host-associated divergence in all colonies examined. {H}owever, isolated populations of the same host type did not always group together in overall analyses and the genetic differentiation among sympatric host races was highly variable. {I}n contrast, little host or geographical structure was found for the mitochondrial gene fragment. {T}hese results suggest that host race formation in {I}. uriae is a recent phenomenon, that it may have occurred several times and that local interactions are at different points in the divergence process. {R}apid divergence in {I}. uriae implies a strong interaction with its local host species, an interaction that will alter the ecological dynamics of the system and modify the epidemiological landscape of circulating micropathogens.},
