Moreover, the vast majority of human social systems show multilevel structure as well 16, 17, 18, 19, 20, thus studying multilevel societies can fundamentally contribute to our understanding of the evolution of sociality 2, 21, 22, 23. They are best known from primates 3, 4, 5, 6, 7, but are also found in cetaceans 8, 9, elephants 10, equids 11, 12, 13, 14, and birds 15. Individuals in these societies aggregate through multiple nested levels 2: the core units (the lowest social level) are usually breeding units (e.g., one-male, multifemale groups), and higher levels of social organisation are formed by the aggregation of lower-level units. Multilevel societies are arguably among the most complex forms of social organisation in nature 1, 2. Understanding social structure and dynamics of animal societies is an important task in which utilising emerging technologies and high-throughput methods could be the key. Our results show that only a few minutes of fine-scale movement tracking combined with high throughput data driven analysis can reveal the structure of a society, reconstruct past group dynamics and predict future ones. High movement similarity of females from different harems predicts becoming harem mates in the future. Harems of genetically related stallions are closer to each other in the network, and female exchange is more frequent between closer harems. The network centrality of harems is related to their age and how long the harem stallions have kept harems previously. Analysis of collective movements reveals how the structure of the herd’s social network is related to kinship and familiarity of individuals.
We track, in high spatio-temporal resolution, the movements of 238 individually identified horses on drone videos, and combine movement analyses with demographic data from two decades of population monitoring.
Here, we present a state-of-the-art drone observation of a multilevel herd of Przewalski’s horses, consisting of harems (one-male, multifemale groups). your presentations or to create your own dvd menu.Studying animal societies needs detailed observation of many individuals, but technological advances offer new opportunities in this field.
