Bivalvia | Venerida | Cyrenoidea

family CYRENIDAE Gray, 1840: cladomics
     6 genera

Cladomics Summary

number of species = 110 (113 total)
number of subtaxa (rank: genus) = 6
analyzed in 4 cladograms in 2 publications
maximum number of terminals in an analysis = 23 (mean = 10.25, median = 6.5)
maximum number of subtaxa (genus) = 3 (mean = 2.25, median = 2.5)

Basic Monophyly

number of cladograms that test basic monophyly (i.e., more than 1 included species) = 4
maximum number of included terminals = 23, (mean = 10.25 median = 6.5)
maximum number of subtaxa (genus) = 3 (mean = 2.25, median = 2.5)
proportion of cladograms that support basic monophyly = 0.75

Rigorous Monophyly

number of cladograms that test rigorous monophyly = 3
(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 = 7 (mean = 6, median = 6)
maximum number of subtaxa (genus) = 3 (mean = 2.67, median = 3)
proportion of cladograms that support rigorous monophyly = 0.67

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.
