subfamily MARGARITIFERINAE Henderson, 1929: cladomics
     3 genera

Cladomics Summary

number of species = 11 (32 total)
number of subtaxa (rank: genus) = 3
analyzed in 266 cladograms in 151 publications
maximum number of terminals in an analysis = 13 (mean = 2.83, median = 2)
maximum number of subtaxa (genus) = 3 (mean = 1.61, median = 1)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 154
maximum number of included terminals = 13, (mean = 4.16 median = 2)
maximum number of subtaxa (genus) = 3 (mean = 2.05, median = 2)
proportion of cladograms that support basic monophyly = 0.87

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 43
(Rigorous monophyly refers to cladograms with terminal species representing more than one subtaxon (genus) taxon and at least one rigorous outgroup (family).
maximum number of included terminals = 13 (mean = 7.77, median = 9)
maximum number of subtaxa (genus) = 3 (mean = 2.91, median = 3)
proportion of cladograms that support rigorous monophyly = 0.7

Pairwise Cladogram Clustering

The graphs below depict in two dimensions all pair-wise ingroup distances within the cladome. See the Cladmoics FARQ for more information.
