Figure S9 - Differences MuSSE hindgut microbiota macroevolutionary rates MCMC

Differences in rates computed from the MCMC analyses using the best MuSSE model for the gut microbiota. The compound figure shows: 1) the differences between speciation rates as made by pair comparisons; 2) the differences between extinction rates; and 3) the differences between net diversification rates. Only the lineages with an entirely prokaryotic gut microbiota have a significant different net diversification rates (i.e. no posterior distribution overlaps with the red line). Eusocial lineages with an entirely prokaryotic hindgut microbiota diversified faster than other lineages (cellulolytic flagellates or no specialized microbiota for lignocellulose digestion).

本数据集基于最优MuSSE模型，通过马尔可夫链蒙特卡洛（Markov Chain Monte Carlo, MCMC）分析计算得到肠道微生物群（gut microbiota）相关的各类速率差异。该组合图包含以下三部分内容：1）成对比较得到的物种形成速率差异；2）灭绝速率差异；3）净多样化速率差异。仅完全拥有原核生物型肠道微生物群的支系，其净多样化速率存在显著差异，即其后验分布与红线无任何重叠。具备完全原核生物型后肠微生物群的真社会性支系，其多样化速率快于其他支系，即携带纤维素分解鞭毛虫或无用于木质纤维素消化的特化微生物群的支系。
