Fig 1.
Phylogram showing the phylogenetic relationship in Anseriformes based on the mito-genomes.
The values on nodes include four parts. The first two values indicate the split time and Bayesian posterior probabilities which were calculated by BEAST 1.7.4. The third values were the Bayesian posterior probabilities calculated by MrBayes 3.2.2, and the last values were the Bayesian posterior probabilities calculated by RAxML version 8. Blue bars at nodes show 95% highest posterior density (HPD) of divergence times.

Phylogram showing the phylogenetic relationship in Anseriformes based on two mitochondrial genes.
The values on nodes indicate the split time and Bayesian posterior probabilities which were calculated by BEAST 1.7.4, “-” indicated that the value was less than 70. Blue bars at nodes show 95% HPD of divergence times.

Lineage-through-time (LTT) plots for Anseriformes birds.
The colored lines represent the results of 1000 trees randomly selected from the BEAST analysis. The ref line shows the MCC tree.

Visualizations of diversification rate shifts within Anseriformes.
(a) Speciation-through-time plots utilizing BAMM. Curved red lines represent the median values with the 95% confidence intervals shown in blue. Arrows point to the three significant shifts in rates of speciation; (b) Posterior distribution of the number of rate shifts.
