Gammarus roeselii sampling sites in this study. Empty dots refer to sites with no microsporidian infections. Black dots refer to sites where at least one infection was found in a G. roeselii individual and for which a sequence was obtained. Site labels refer to Additional file 1: Table S1. The enlarged geographical zone corresponds to area of ancient diversification of G. roeselii (thereafter named Region 1). Other sites are located either in the geographical zone of secondary diversification of G. roeselii (Region 2a) or in the area of recent, post-glacial, expansion (Region 2b)
