Cladomics Summary

number of species = 3 (3 total)
analyzed in 3 cladograms in 1 publication
maximum number of terminals in an analysis = 1 (mean = 1, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 0
maximum number of included terminals = , (mean = median = )
proportion of cladograms that support basic monophyly = 0
