“…The first approach involves comparing the topology of different networks as an outcome of other network properties (e.g., network size). This is common in network science where understanding the generative processes underlying network formation is a major focus (e.g., Ojer & Pastor-Satorras, 2022;Rocha et al, 2021;Ward, 2021). However, it is also of interest to ecologists, such as with studies that test the relationship between network size and modularity (Griffin & Nunn, 2012).…”

“…Several studies (6/49 = 12%) used animal social network meta‐datasets to illustrate new methods or confirm trends in network science or related fields. These included identifying novel scaling trends (Ojer & Pastor‐Satorras, 2022; Rocha et al., 2021; Ward, 2021), producing new approaches (McDonald & Hobson, 2018; Ojer & Pastor‐Satorras, 2022; Shizuka & Farine, 2016; Ward, 2021) or deriving new network traits (Péron, 2023).…”

Social systems vary enormously across the animal kingdom, with important implications for ecological and evolutionary processes such as infectious disease dynamics, anti‐predator defence, and the evolution of cooperation. Comparing social network structures between species offers a promising route to help disentangle the ecological and evolutionary processes that shape this diversity. Comparative analyses of networks like these are challenging and have been used relatively little in ecology, but are becoming increasingly feasible as the number of empirical datasets expands. Here, we provide an overview of multispecies comparative social network studies in ecology and evolution. We identify a range of advancements that these studies have made and key challenges that they face, and we use these to guide methodological and empirical suggestions for future research. Overall, we hope to motivate wider publication and analysis of open social network datasets in animal ecology.

We study the synchronization properties of a generic networked dynamical system, and show that, under a suitable approximation, the transition to synchronization can be predicted with the only help of eigenvalues and eigenvectors of the graph Laplacian matrix. The transition comes out to be made of a well defined sequence of events, each of which corresponds to a specific clustered state. The network’s nodes involved in each of the clusters can be identified, and the value of the coupling strength at which the events are taking place can be approximately ascertained. Finally, we present large-scale simulations which show the accuracy of the approximation made, and of our predictions in describing the synchronization transition of both synthetic and real-world large size networks, and we even report that the observed sequence of clusters is preserved in heterogeneous networks made of slightly non-identical systems.
