Sampling density, calculated as a percentage of species listed for the CFR by [12], was determined by the availability of both DNA sequence and usable geospatial data. Also indicated are the gene regions analysed, and the substitution models determined as optimal by MrModeltest 2.3. The source publication for each data set is shown.
