Identifying timescales of change in vulture social networks

Animal social interaction patterns change over time, but the continuous nature of social interactions makes selecting a timescale for temporal analysis challenging. We applied both a heuristic approach and a multilayer reducibility analysis approach to study timescales of change in social networks of free-ranging griffon vultures. We analyzed social networks in two behavioral situations: in-flight interactions, such as during foraging movements, which we expected to fluctuate seasonally but to exhibit a relatively constant pattern of change over the course of a season; and diurnal ground interactions, such as interactions while feeding, which we expected to show a pulsed temporal pattern that followed the pattern of carcass availability on the landscape. The heuristic method confirmed the suitability of a 3-10 day aggregation window for studying temporal change in vulture social networks. It also highlighted how different timescales of aggregation offer different insights about longer-t..., , # Data from: Identifying timescales of change in vulture social networks
