Fig. 2From: Population structure and dispersal routes of an invasive parasite, Fascioloides magna, in North America and EuropeGenetic population structure of Fascioloides magna from all North American (NA) and European (EU) populations (a), and interrelationships among NA populations (b-d) derived from PRINCIPAL COORDINATES ANALYSIS (PCoA). Circles, EU natural foci; squares, NA enzootic regions. a All NA and EU populations. b All NA populations. c Eastern NA clade inferred from mt data (Bazsalovicsová et al. [10]). d West-east NA lineage derived from MIGRATE analysis of microsatellites (present study). Codes for NA enzootic regions and EU natural foci are explained in Tables 1 and 2, respectivelyBack to article page
