Diversification of Syngnathidae and Solenostomidae through time. The colors on the phylogenetic tree show branch-specific estimates of net diversification rates (i.e., speciation rate minus extinction rate) from ClaDS. The curve is showing tree-wide net diversification rate estimated using an episodic birth–death model in RevBayes. The mean estimate is the gray line, and the light gray shading represents 95% HPD intervals. The vertical dashed lines indicate major geographic events, which are illustrated in the maps below with reconstructions of shallow seafloor areas in light blue (plotted with data from [64])
