Before revision:  A recent advancement in network science,multilayer network analysis , the study of network structures of multiple interconnected 'layers' and associated dynamical processes, offers a novel way to represent and analyze animal behavior. It also helps strengthen the links between animal social behavior and broader ecological and evolutionary contexts and processes.
After revision:  A recent advancement in network science,multilayer network analysis , the study of network structures of multiple interconnected 'layers' and associated dynamical processes, offers a novel way to represent and analyse animal behaviour as connected `layers' of interactions.
