Speciation in progress? A phylogeographic study among populations of Hemitrichia serpula (Myxomycetes)
Fig 4
Statistical parsimony ribotype network representing genealogical relationships among 40 ribotypes estimated by TCS superimposed on a Bayesian interference tree.
Grey triangles are sized relative to the number of specimens per network. Line segments represent mutational steps between alleles. Circles are scaled in proportion to the number of sequences represented by each ribotype. Small circles between ribotypes indicate hypothetical transitional ribotypes. Colors designate the origin of the specimen. Morphotypes displayed by specimens showing the respective ribotype are indicated by smooth (var. serpula) or broken lines (var. parviverrucospora).
