Effect of diet on the structure of animal personality

摘要: There is increasing interest in the proximate factors that underpin individual variation suites of correlated behaviours. In this paper, we propose dietary macronutrient composition, an underexplored environmental factor, might play a key role. Variation composition can lead to among-individual differentiation single behaviours (‘personality’ ) as well covariation between (‘behavioural syndromes’ ). Here, argue nutritional balance during any life stage affect development syndrome structure and expression genes with pleiotropic effects influence multiple behaviours, hence genetic structure. We further suggest males females should typically differ diet-dependent despite shared basis. detail how such multivariate gene-environment interactions have major repercussions for evolution behavioural syndromes.
