Understanding why animal societies take on the form that they do has
benefited from insights gained by applying social network analysis to
patterns of individual associations. Such analyses typically aggregate
data over long time periods even though most selective forces that shape
sociality have strong temporal elements. By explicitly incorporating the
temporal signal in social interaction data we re-examine the network
dynamics of the social systems of the evolutionarily closely-related
Grevy’s zebras and wild asses that show broadly similar social
organizations. By identifying dynamic communities, previously hidden
differences emerge: Grevy’s zebras show more modularity than wild asses
and in wild asses most communities consist of solitary individuals; and in
Grevy’s zebras, lactating females show a greater propensity to switch
communities than non-lactating females and males. Both patterns were
missed by static network analyses and in general, adding a temporal
dimension provides insights into differences associated with the size and
persistence of communities as well as the frequency and synchrony of their
formation. Dynamic network analysis provides insights into the functional
significance of these social differences and highlights the way dynamic
community analysis can be applied to other species.
Grevy's zebra and wild asses affiliation groupsAffiliation groups
over time for grevy's zebra and wild asses. Data in contains three
columns: day, group no., individual id. Day is the day (an encoding of a
date) on which the groups of animals have been sighted. Group no. is the
unique group id for each sighted group. All animals with the same group
no. have been seen together. All group numbers are unique and do not
repeat across days. Animal id is the unique identifier of an individual
animal. The letter after the id indicates demographic status: Grevy's
