Fig. 3 in Evidence of cryptic speciation in the invasive hydroid Cordylophora caspia (Pallas, 1771) (Cnidaria, Hydrozoa) supported by new records

Fig. 3 Ancestral states reconstruction of habitat preferences of Cordylophora caspia based on salinity. Pie diagrams and numbers at nodes indicate proportional likelihoods of each state, with freshwater (orange) or brackish (black) habitats. a Reconstruction based on Bayesian topology; b reconstruction based on ML topology (see Phylogenetic Analysis section in Material and Methods). Number in parenthesis indicate clades nomenclature as in Fig. 2. See Table S1 for additional information and references
