How different levels of biological organization interact to shape each other's function is a central question in biology. One particularly important topic in this context is how individuals' variation in behaviour shapes group-level characteristics. We investigated how fish that express different locomotory behaviour in an asocial context move collectively when in groups. First, we established that individual fish have characteristic, repeatable locomotion behaviours (i.e. median speeds…

Consistent individual differences drive collective behaviour and group functioning of schooling fish
Analysis of high-resolution tracking data of known individuals demonstrates that, across a range of contexts, consistent inter-individual differences in social proximity were strongly linked to speed and, together with boldness predicted spatial positioning and leadership within groups, differences in structure and movement dynamics between groups.
Individual-level personality influences social foraging and collective behaviour in wild birds
It is demonstrated that variation in personality promotes within-patch movement while maintaining group cohesion, illustrating the importance of incorporating individual variability in models of social behaviour.
The importance of individual variation in the dynamics of animal collective movements
The need to consider variability at the level of the individual to improve the understanding of how individual decision rules lead to emergent movement patterns, and also to yield better quantitative predictions of collective behaviour is underscored.
Personality variation is eroded by simple social behaviours in collective foragers
The movement of groups can be heavily influenced by ‘leader’ individuals who differ from the others in some way. A major source of differences between individuals is the repeatability and consistency
Impact of Variable Speed on Collective Movement of Animal Groups
It is shown, that besides average speed, the individual speed variability may have a dramatic impact on the emergent collective dynamics, as two groups differing only in their speed variability, and being otherwise identical in all other behavioral parameters, can be in two fundamentally different stationary states.
Group-level patterns emerge from individual speed as revealed by an extremely social robotic fish
It is shown that individual differences in guppies’ movement speed were highly repeatable and shaped key collective patterns: higher individual speeds resulted in stronger leadership, lower cohesion, higher alignment, and better temporal coordination in the pairs.
Using activity and sociability to characterize collective motion
It is suggested that the activity and sociability axes provide a useful framework for measuring the behaviour of animals in groups, allowing the comparison of individual and collective behaviours within and between species.
A statistical method for identifying different rules of interaction between individuals in moving animal groups
A set of randomization methods designed to determine statistical differences in the rules of interaction between individuals are introduced and applied to a case study of leaders and followers in pairs of freely exploring eastern mosquitofish.


Collective memory and spatial sorting in animal groups.
The first evidence for collective memory is presented in such animal groups (where the previous history of group structure influences the collective behaviour exhibited as individual interactions change) during the transition of a group from one type of collective behaviour to another.
Deciphering Interactions in Moving Animal Groups
Using video tracks of fish shoal in a tank, it is shown how a careful, incremental analysis at the local scale allows for the determination of the stimulus/response function governing an individual's moving decisions, yielding a novel schooling model whose parameters are all estimated from data.
Express your personality or go along with the group: what determines the behaviour of shoaling perch?
Most fish showed a shyer behaviour when alone, but bolder individuals changed less between treatments than did shyer ones, suggesting a more influential role of bold fish in the group.
Inferring the rules of interaction of shoaling fish
Three key rules for the social interactions of mosquitofish (Gambusia holbrooki) are identified, which are different from the classical models of collective animal motion, raising new questions about how fish and other animals self-organize on the move.
Personality and collective decision-making in foraging herbivores
A mathematical model based on behavioural rules derived from experiments, in which crowding and conspecific attraction affect the probability of entering or leaving patches, predicts that resource fragmentation more strongly affects the distribution patterns of shy groups and suggests that the presence of both bold and shy individuals within groups would result in more flexible behaviour at the population level.

This review examines the state of knowledge on the relationship between individual personality and sociality, and considers the influence of the social context on individual personality responses, the interaction between the collective personalities of group members and the expression of those personalities in the individual.
Personality in the context of social networks
The social fine-structure of animal populations (as quantified by social network analysis) can have important consequences for the evolution of personalities—an approach that goes beyond the conventional game-theoretic analyses that assumed random mixing of individuals in populations.
