Table 2. Bayes factor hypothesis testing for four alternate C. vittatus phylogenies.

Constraint	lnL harmonic mean(post burnin)	Bayes Factor	Support for Rejection
Unconstrained Phylogeny	−6786.32	–	–
Hypo 1: support for C. pantheriensis clade	−7201.266	829.90	very strong
Hypo 2: single origin of Tularosa NM populations	−6792.47	12.31	very strong
Hypo 3: Single origin in similar ecological niche	−6926.60	280.56	very strong
Hypo 4: Separate origin of western andeastern clades	−7122.50	672.36	very strong
