Genetic correlations among developmental and contextual behavioral plasticity in Drosophila melanogaster

Correlations among traits, including behaviors, are important because traits that are genetically correlated may not evolve independently. Recently, behavioral correlations research has expanded to include correlations not only in mean-level behaviors, but also in behavioral plasticity, i.e., the degree to which individuals change their behavior in response to environmental stimuli. Positive correlations among behavioral plasticities would imply that individuals or genotypes that are behaviorally plastic in one way may also be plastic in other ways; negative correlations could imply tradeoffs. Here, we examine aversive odor conditioning (learning) at two time points, and plasticity in pupation site selection behavior across substrates, in a panel of Drosophila genotypes. These behaviors represent different types of behavioral plasticity: contextual plasticity describes behavioral responses to stimuli that are currently present, while developmental plasticity describes behavioral res...
