Figure 1.

Differential gene expression between generalists and trophic specialists. Red points represent genes that are differentially expressed in 8–10 dpf whole‐larvae tissue (A, C) and 17–20 dpf craniofacial tissue (B, C) between generalists versus scale‐eaters (A, B) and generalist versus snail‐eaters (C, D). Bottom panels show the first and second principal component axes accounting for a combined 52% (8–10 dpf; E) and 48% (17–20 dpf; F) of the total variation between samples across 413 million reads mapped to annotated features. Triangles represent samples from Little Lake and circles represent samples from Crescent Pond on San Salvador Island.
