Resource‐based trade‐offs and the adaptive significance of seasonal plasticity in butterfly wing melanism by Stoehr, Andrew M., Glaenzer, Katelyn, VanWanzeele, Devin, Rumschlag, Samantha

“…Phenotypic plasticity is the ability of an organism to alter its phenotype in response to environmental cues. This can be adaptive if the cues are reliable…”

Eyespots deflect predator attack increasing fitness and promoting the evolution of phenotypic plasticity by Prudic, Kathleen L., Stoehr, Andrew M., Wasik, Bethany R., Monteiro, Antónia

“…Some eyespots are thought to deflect attack away from the vulnerable body, yet there is limited empirical evidence for this function and its adaptive…”

Inter- and intra-sexual variation in immune defence in the cabbage white butterfly, Pieris rapae L. (Lepidoptera: Pieridae) by STOEHR, ANDREW M

“…1. Immune defence imposes fitness costs as well as benefits, so organisms are expected to optimise, not maximise, their immune responses. This should result in…”
