Figure 4. Evolution of transcript expression plasticity. (A) We
grouped transcripts with significant interaction effects into one of
four categories based on patterns of evolution in expression plasticity:
(1) Assimilated: plasticity in the ancestral high-predation population
but a loss of plasticity in the derived low-predation population; (2)
Accommodated: a change in the degree, but no the direction, of
plasticity in the derived as compared to the ancestral population; (3)
Evolved plastic: no plasticity in the ancestral high-predation
population but an emergence of plasticity in the derived low-predation
population; (4) Reversed: opposing directions of plasticity in high-
versus low-predation populations. We categorized remaining transcripts
that had a significant main interaction effect, but no significantpost hoc rearing differences as unclassified. Adapted from Renn
& Schumer (2013). (B) All categories were represented in both Aripo and
Quare datasets.
