Model selection results of alternative phylogenetic hypothesis testing
hypothesis ΔAICM ln BFPS ln BFSS
monophyletic American Carychium 0.00 0.00 0.00
monophyletic Asian Carychium −14.07 17.24 17.66
unconstrained phylogeny −18.96 44.86 45.14
monophyletic Alpine Zospeum −157.41 85.25 85.81
monophyletic Dinaric Zospeum −345.81 191.58 190.53

Results of the model selection approach to test the monophyly of geographically closely distributed taxa. Hypotheses are ranked according to model fit. AICM = modified Akaike Information Criterion; BFPS = Bayes Factor based on path simulation sampling; BFSS = Bayes Factor based on stepping stone sampling. A ΔAICM >7 and a ln BF > 2.3 are seen as strong model support.
