Fig. 3From: Population structure and dispersal routes of an invasive parasite, Fascioloides magna, in North America and EuropeGenetic population structure of Fascioloides magna from European (EU) populations (a) and interrelationships between EU and North American (NA) populations (b-d) based on the PRINCIPAL COORDINATES ANALYSIS (PCoA). Circles, EU natural foci; squares, NA enzootic regions. a Interrelationships between F. magna from Czech-Polish (CZ-PL) and Danube floodplain forests (DFF) foci. b Relatedness between flukes from Italy (IT) and western NA regions (RMT and NPC). c Comparison between F. magna from CZ-PL and particular states of SAS. d Differentiation of DFF from all NA enzootic regions. Codes for NA enzootic regions and EU natural foci are explained in Tables 1 and 2, respectivelyBack to article page
