FIGURE 1 in The genus Echinolittorina Habe, 1956 (Gastropoda: Littorinidae) in the Indo-West Pacific Ocean

FIGURE 1. Molecular phylogeny of Echinolittorina species produced by Bayesian analysis of concatenated gene sequences from 28S rRNA, COI and 12S rRNA genes (outgroups removed). Branches with posterior probability (PP) <90% are grey, branches with PP 90% are black. The three measures of nodal support are: posterior probability / bootstrap (neighbour-joining algorithm) / bootstrap (maximum likelihood). Support values are only shown when at least two support values are>50%. Geographical occurrence is shown, with Indo-West Pacific taxa (subgenus Granulilittorina) being enclosed in a grey box. Also shown are the informal groups used in the Systematic Descriptions. (Phylogeny after Williams & Reid 2004).
