Fig. 3.

Relationships between the proportions of repetitive elements across Synalpheus species (n = 33) with different forms of social organization (A–D), and with the eusociality index (E–H). The y axes are the proportions of all TEs (A and E), LTRs (B and F), unknown TE subclass (C and G), and microsatellite repeats (D and H). Raw values are shown in shapes (○: pair-living; △: communal breeding; ■: eusocial; jittered along the x axes in A–D). Posterior means and 95% CI based on phylogenetic mixed models are show as closed circles and error bars in A–D and regression lines and shaded areas in E–H. In A–D, letters indicate significant differences in the posterior means in pair-wise comparisons between forms of social organization (a, b, and c) and planned comparisons between eusocial and noneusocial species (A and B) (pMCMC < 0.05).
