Before revision:  A recent advancement in network science, multilayer network analysis, the study of network structures of multiple interconnected `layers' , offers a novel way to represent and analyze the structure of animal behavior, and help strengthen links to broader ecological and evolutionary contexts . We outline the potential uses of these new methods at individual-, group-, population-, and evolutionary-levels, and we highlight their potential to advance behavioral ecology research .
After revision:  A recent advancement in network science, multilayer network analysis, the study of network structures of multiple interconnected `layers' , offers a novel way to represent and analyze the structure of animal behavior, and help strengthen links to broader ecological and evolutionary contexts and processes. In this article, we describe how to encode animal behavior data as different types of multilayer networks, and we link recently-developed multilayer methods to individual-, group-, population-, and evolutionary-levels, and we highlight their potential to advance behavioral ecology research .
