Table 3 Results of bottleneck analyses performed with the software Bottleneck version 1.2.02 (Cornuet and Luikart, [52]) and the program MPval [51] to calculate the M-ratio and M-critical with θ = 10 for each of the 27 populations

  1. Values in bold show a significant bottleneck detected
  2. For the heterozygosity excess test, we tested a stepwise mutation model, an infinite alleles model and a two-phase mutation model with 12 % multistep mutations and a variance = 0.36. M-ratio average was calculated across loci. Mc is the critical M-value calculated through the M-crit program developed by Garza and Williamson [51]. M-ratio test is significant if M-Ratio < Mc
  3. aM-Ratio = number of alleles/range in allele size and range (size of largest allele - size of smallest allele + 1)
  4. bMc is defined such that only 5 % of the simulation values fall below this threshold
