Abstract: | The theory of collective motion and the study of animal social networks have, each individually, received much attention.
Currently, most models of collective motion do not consider social network structure. The implications for considering collective
motion and social networks together are likely to be important. Social networks could determine how populations move in, split
up into and form separate groups (social networks affecting collective motion). Conversely, collective movement could change
the structure of social networks by creating social ties that did not exist previously and maintaining existing ties (collective
motion affecting social networks). Thus, there is a need to combine the two areas of research and examine the relationship
between network structure and collective motion. Here, we review different modelling approaches that combine social network
structures and collective motion. Although many of these models have not been developed with ecology in mind, they present
a current context in which a biologically relevant theory can be developed. We argue that future models in ecology should
take inspiration from empirical observations and consider different mechanisms of how social preferences could be expressed
in collectively moving animal groups. |
