Table 1 Results of bayes factor delimitation (BFD*) analyses for the humboldtianum group using three SNPs subsets (ranging from 39 to 59 individuals, and 411–1102 SNP loci)

From: Genome-wide species delimitation analyses of a silverside fish species complex in central Mexico indicate taxonomic over-splitting

  1. Bayes factor (BF) calculations are estimated against the model with the best marginal-likelihood estimate (Model 1). Positive BF values indicate support for model 1 (the best model). Overall, these analyses support a species delimitation scenario between four and five species, rejecting the nine morphospecies scheme
  2. MLE: marginal likelihood estimates. Bold values correspond to the best model selected by the analysis. NA correspond to not applied, and its associated marginal likelihood is in bold. 0 < BF < 2, non-significant; 2 < BF < 6, positive evidence; 6 < BF < 10, strong support; BF > 10, decisive support
