Fig. 4From: Phylogenetic positions of “pico-sized” radiolarians from middle layer waters of the tropical PacificA phylogenetic tree of RAD III based on 18S rDNA sequences. Sequences obtained from the Central Pacific Ocean in this study are in bold. Numbers at the nodes represent posterior probabilities (PP) of the Bayesian inferences, bootstrap values (BV) of the ML analysis. The scale bar in the upper left corner is the substitution rate per site for the Bayesian analyses. Sequences obtained in this study are shown in boldBack to article page
