 social

relationships by regulating the dynamics of territoriality, hierarchy, predation and resource utilization.

The expression of aggressive behaviour develops as an individual ages and is often shaped by social

experience. Even though the heritability of traits that yield dominantesubordinate relationships is high,

strong environmental influences also shape the expression of these individual behaviours. In this study

we present evidence for the first time of a necessary interplay between factors that generate behavioural

phenotypic plasticity in zebrafish. Select presumptively genetic and environmental elements interacted

developmentally to produce the behavioural phenotypes necessary for dominantesubordinate relationships

in dyads. Aggressive and submissive acts increased in focus and intensity and were correlated

with social rank during development, but decreased with duration of the paired interaction.
