1. Animal social networks are descriptions of structure which, aside from their intrinsic interest for understanding sociality, can have significant bearing across many fields biology. 2. Network analysis provides a flexible toolbox testing broad range hypotheses, and describing the system species or populations in quantitative comparable manner. However, it requires careful consideration underlying assumptions, particular differentiating real observed controlling inherent biases that common...
Baboons follow the pack, not leader How do groups of animals, including humans, make decisions that affect entire group? Evidence collected from schooling animals suggests process is somewhat democratic, with nearest neighbors and majority shaping overall collective behavior. In hierarchical social structures such as primates or wolves, however, democracy may be complicated by dominance. Strandburg-Peshkin et al. monitored all individuals within a baboon troop continuously over course their...
Summary Null models are an important component of the social network analysis toolbox. However, their use in hypothesis testing is still not widespread. Furthermore, several different approaches for constructing null exist, each with relative strengths and weaknesses, often hypotheses. In this study, I highlight why robust studies animal networks. Using simulated data containing a known observation bias, test how statistical tests perform if such bias was unknown. show that permutations raw...
Animals use social information in a wide variety of contexts. Its extensive by individuals to locate food patches has been documented number species, and various mechanisms discovery have identified. However, less is known about whether differ their access to, of, find food. We measured the network wild population three sympatric tit species (family Paridae) then recorded individual novel patches. By using recently developed methods for network-based diffusion analysis, we show that order...
Summary The sampling of animals for the purpose measuring associations and interactions between individuals has led to development several statistical methods deal with biases inherent in these data. However, are typically computationally intensive complex implement. Here, I provide a software package that supports range analyses R computing environment. This includes novel approach estimating re‐association rates time frequently sampled individuals. include extended demonstration syntax...
Social environments have an important effect on a range of ecological processes, and form crucial component selection. However, little is known the link between personality, social behaviour population structure. We combine well-understood personality trait with large-scale networks in wild songbirds, show that underpins multiple aspects organisation. First, we demonstrate relationship network centrality 'proactive' (fast-exploring) individuals associating weakly greater numbers conspecifics...
There is increasing evidence that animal groups can maintain coordinated behaviour and make collective decisions based on simple interaction rules. Effective action may be further facilitated by individual variation within groups, particularly through leader–follower polymorphisms. Recent studies have suggested individual-level personality traits influence the degree to which individuals use social information, are attracted conspecifics, or act as leaders/followers. However, equivocal...
Abstract Many animal social structures are organized hierarchically, with some individuals monopolizing resources. Dominance hierarchies have received great attention from behavioural and evolutionary ecologists. There many methods for inferring interactions. Yet, there no clear guidelines about how observed dominance interactions (i.e. sampling effort) necessary reliable hierarchies, nor any established tools quantifying their uncertainty. We simulate (winners losers) in scenarios of...
Understanding the functional links between social structure and population processes is a central aim of evolutionary ecology. Multiple types interactions can be represented by networks drawn for same population, such as kinship, dominance or affiliative networks, but relative importance alternative in modulating may not clear. We illustrate this problem, solution, developing framework testing different association facilitating transmission information. apply to experimental data from wild...
Animal societies are shaped both by social processes and the physical environment in which interactions take place. While many studies observed patterns of inter-individual as products proxies pure processes, or links between resource availability structure, role configuration habitat features shaping system group-living animals remains largely overlooked. We hypothesise that decisions about when where to move, will impact individuals more frequently encounter one another doing so overall...
Abstract Individual identification is a crucial step to answer many questions in evolutionary biology and mostly performed by marking animals with tags. Such methods are well‐established, but often make data collection analyses time‐consuming, or limit the contexts which can be collected. Recent computational advances, specifically deep learning, help overcome limitations of collecting large‐scale across contexts. However, one bottlenecks preventing application learning for individual need...
Movement is a key part of life for many species. In solitary animals, the energetic costs movement can be mitigated through energetically efficient strategies that produce faster, straighter movements. However, little known about whether moving as collective enhances or limits ability individual group members to express such strategies. Drawing on 6 years population-level, high-resolution (1 Hz) GPS tracking group-living vulturine guineafowl ( Acryllium vulturinum ), we detected 886 events...
Cooperative breeding in birds is thought to be more common altricial species, with few described cases precocial species. However, cooperative may also difficult detect species and could have been overlooked. We investigated whether Vulturine Guineafowl Acryllium vulturinum breed cooperatively and, if so, how care distributed among group members. collected data from 51 uniquely marked individuals (27 males, 24 females), of which 13 females bred at least once over three different seasons....
Despite growing interest in animal social networks, surprisingly little is known about whether individuals are consistent their network characteristics. Networks rarely repeatedly sampled; yet an assumption of individual consistency behaviour often made when drawing conclusions the consequences processes and structure. A characterization such phenotypes therefore vital to understanding significance structure for fitness outcomes, evolution ecology variation more broadly. Here, we measured...

Individual heterogeneity can influence the dynamics of infectious diseases in wildlife and humans alike. Thus, recent work has sought to identify behavioural characteristics that contribute disproportionately individual variation pathogen acquisition (super-receiving) or transmission (super-spreading). However, it remains unknown whether same behaviours enhance both transmission, a scenario likely result explosive epidemics. Here, we examined this possibility an ecologically relevant...
For group-living animals traveling through heterogeneous landscapes, collective movement can be influenced by both habitat structure and social interactions. Yet research in behavior has largely neglected influences on movement. Here we integrate simultaneous, high-resolution, tracking of wild baboons within a troop with 3-dimensional reconstruction their to identify key drivers baboon A previously unexplored influence – baboons’ preference for locations that other members have recently...
