18. Keynote: Butterfly eyespots and exploring developmental bias

Paul Brakefield

Bias in how development generates a morphology can in theory constrain the independent evolution of traits sharing ontogenetic pathways, making certain evolutionary changes more likely than others. The eyespots on butterfly wings are classic examples of serially repeated pattern elements and have been a focus for evo-devo research over recent decades. Previous work on a model species of...

19. A meta-analytical study of the concordance of plastic and evolutionary responses

Developmental bias is the non-random generation of phenotypes as a result of developmental processes; making some (combinations of) phenotypes more likely than others. Developmental bias is clearly widespread, but there is little insight in the generality of the patterns, nor in their evolutionary consequences. Here, we take a meta-analytical approach and test whether environmentally induced...

20. The role of developmental plasticity in the evolution of crypsis in a freshwater isopod

Natural selection and phenotypic plasticity can both contribute to ecologically relevant trait variation within and among populations. Previous work suggests that variation in cryptic pigmentation of freshwater isopods (Asellus aquaticus) has evolved in response to predation pressure by fish in habitats with varying macrophyte cover and coloration. However, more recent evidence suggests that...
