Table 4 Analyses of population size changes. Wilcoxon sign-rank tests for heterozygosity excess in native and introduced areas of Fascioloides magna under a two-phase model (TPM) and stepwise mutation model (SMM) from BOTTLENECK and coalescent estimates of Theta (Θ) for source and introduced F. magna populations

  1. aCodes for North American enzootic regions and European natural foci are explained in Tables 1 and 2, respectively
  2. BOTTLENECK notes: *two loci out of 11 analysed were monomorphic in the IT population, Hex/Ht ratio of the number of loci with a heterozygosity excess to the total number of analysed polymorphic loci, P statistical significance of any deviation from equilibrium expectations
  3. MIGRATE notes: 2.5 and 97.5 % demarcate the 95 % confidence interval of Theta estimates, italicized numbers the mode and mean values of Theta. MIGRATE estimates for NPC and IT, and for SC, CZ, SK, HU and CR originated from two separate runs
