To predict evolutionary responses of warning signals under selection, we need to determine the inheritance pattern of the signals, and how they are genetically correlated with other traits contributing to fitness. Furthermore, protective coloration often undergoes remarkable changes within an individual's lifecycle, requiring us to quantify the genetic constraints of adaptive coloration across all the relevant life stages. Based on a 12 generation pedigree with > 11,000 individuals of the wood tiger moth (Arctia plantaginis), we show that high primary defense as a larva (large warning signal) results in weaker defenses as adult (less efficient warning color), due to the negative genetic correlation between the efficacy of larval and adult warning coloration. However, production of effective warning coloration as a larva did not incur any life-history costs and was positively genetically correlated with reproductive output. These results provide novel insights into the evolutionary constraints on protective coloration in animals, and explain the maintenance of variation in the signal expression despite the strong directional selection by predators. By analyzing the genetic and environmental effects on warning signal and life-history traits in all relevant life stages, we can accurately determine the mechanisms shaping the evolutionary responses of phenotypic traits under different selection environments. ...

Predator-Induced Plasticity on Warning Signal and Larval Life-History Traits of the Aposematic Wood Tiger Moth, Arctia plantaginis Abondano Almeida, Diana; Mappes, Johanna; Gordon, Swanne (Frontiers Media SA, 2021)Predator-induced plasticity in life-history and antipredator traits during the larval period has been extensively studied in organisms with complex life-histories. However, it is unclear whether different levels of predation ...
Appearance before performance? : Nutritional constraints on life‐history traits, but not warning signal expression in aposematic moths Lindstedt, Carita; Suisto, Kaisa; Mappes, Johanna (Wiley; British Ecological Society, 2020)1.Trade‐offs have been shown to play an important role in the divergence of mating strategies and sexual ornamentation, but their importance in explaining warning signal diversity has received less attention. In aposematic ...
Predator-induced plasticity on the life-history and antipredator defenses of the aposematic wood tiger moth larva Abondano Almeida, Diana (2017)Defense mechanisms in organisms evolve as a response of predator-prey interactions, reducing prey mortality. Flexibility in antipredator strategies due to heterogeneous environments can be explained by phenotypic ...
