Fig. 4From: Dictyocoela microsporidia diversity and co-diversification with their host, a gammarid species complex (Crustacea, Amphipoda) with an old history of divergence and high endemic diversityGeographic distribution of Dictyocoela spp infecting Gammarus balcanicus. Maps a, b and c refers to Dictyocoela berillonum (blue) and D. duebenum (grey), D. muelleri (red) and D. roeselum (green), respectively. Each map shows: (i) sites with infections found in G. balcanicus (large colored dots including haplogroup numbers and diamonds, for present study and literature data, respectively), (ii) presence of parasites in other amphipods (for information, small black dots) and (iii) non-infected sites from this study (small empty dots) (see Additional files 1 and 2 for further details). Maps are focusing on south-west Europe, but infections in Scandinavia, Lake Baikal region and USA are also known (Additional files 2 and 4).
