Plots showing difference between egg groups in terms of eggshell ultrastructure variables

(A) Eggshell thickness relative to egg volume, (B) PL thickness relative to egg volume, (C) ML thickness relative to egg volume, (D) PL proportional thickness, (E) PL thickness relative to eggshell thickness, and (F) ML thickness relative to eggshell thickness against egg groups. Data are represented as means of posterior densities (squares) and associated 95% credible intervals (bars). Lowercase letters indicate significant differences between the means of groups (p ≤ 0.05). Legend, AM-hosts: American hosts, AS-hosts: Asian hosts, EU-hosts: European hosts. Response variable definitions are in Table 1 and STAR Methods. For additional comparative numerical data, see Tables 2 and S3–S8.
