  abstract = {{A}ntagonistic interactions between hosts and parasites are key structuring forces in natural populations. {D}emographic factors like extinction, migration and the effective population size shape host-parasite metapopulational dynamics. {T}herefore, to understand the evolution of host-parasite systems it is necessary to study the distribution of the genetic variation of both entities simultaneously. {I}n this paper, we investigate the population genetics co-structure of parasites and hosts within a metapopulation of the liver fluke, {F}asciola hepatica, and two of its intermediate hosts, the main intermediate host in {E}urope, {G}alba truncatula, and a new intermediate host, {O}mphiscola glabra, in {C}entral {F}rance. {O}ur results reveal an absence of specificity of flukes as regard to the two alternative hosts though {O}. glabra shows higher prevalence of {F}. hepatica. {H}ost and parasites displayed contrasting population genetics structure with very small, highly inbred (selfing) and strongly isolated {G}. truncatula populations and much bigger, panmictic and more dispersive {F}. hepatica. {T}his could indicate a local adaptation of the parasite and a local maladaptation of the host. {W}e also unveil a parasite-mediated biased population genetics structure suggesting that infected {G}. truncatula disperse more; have higher dispersal survival than uninfected snails or, more likely, that immigrant snails are infected more often than local snails (local parasites are less adapted to local hosts). {F}inally, an absence, or at least an ambiguous signature of isolation by distance was observed in both host and parasite population. {A} very weak migration rate for {G}. truncatula provides a reasonable explanation for this ambiguous result. {A}lternatively, smaller sample sizes combined with modest migration rates might explain the difficulties to unveil the signal in {F}. hepatica.},
