Social animals live in complex and variable socio-ecological environments
where individuals adapt their behaviour to local conditions. Recently,
there have been calls for studies of animal social networks to take
account of temporal dynamics in social relationships as these have
implications for the spread of information and disease, group cohesion,
and the drivers of sociality, and there is evidence that maintaining
stable social relationships has fitness benefits. It has recently been
recognised that male elephants form strong social bonds with other males.
The nature of these relationships, and thus network structure, may vary
over time in response to environmental conditions and as individuals age.
Using social network analysis, we examine the stability of relationships
and network centrality in a population of male African elephants. Our
results suggest that males may maintain stable social relationships with
others over time. Older males show greater stability in network centrality
than younger males, suggesting younger males face uncertainty in
transitioning to adult society. For elephants, where older individuals
function as social repositories of knowledge, maintaining a social network
underpinned by older males could be of particular importance. eledata_supplementary_materialsData describing associations among non-musth male elephants observed in male-only groups (bull groups, or lone bulls). Elephants were assumed to be associating under the Gambit of the Group assumption, where each elephant observed in a group was assumed to be associating with each other elephant in the group. Column headers are: ID, Group_Type ("LB" = Lone Bull, "B" = "Bull group"), Datetime, sampperiod (sampling period/SP of observation), age (mean estimated age over the sampling period), and group (a numeric value indicating which group each individual was observed in).
