Figure 3: Correlation coefficients of speciation rate and palaeo-temperature.
From: Global cooling as a driver of diversification in a major marine clade

Each panel shows a histogram of correlation coefficients between paleao-temperature and the 9,000 diversification analyses. Panel (a) shows the result of analyzing the whole tree using both Pearson’s R and DCCA (see methods) with a mean correlation coefficient of −0.709. Additional panels (b–g) show the results of the DCCA correlation for each clade that showed a significant rate shift, with the mean correlation and an estimate of the error. Clades are (from top right to bottom left): (b) Paguridae+Lithodoidea (clade 2 in Fig. 1), (c) Diogenidae+Coenobitidae (clade 3 in Fig. 1), (d) Porcellanidae (clade 4 in Fig. 1), (e) Paramunida (clade 6 in Fig. 1), (f) Munida (clade 5 in Fig. 1) and (g) Aegloidea (clade 1 in Fig. 1).
