Herds of ungulates, flocks of birds, swarms of insects and schools of fish move in
coordinated groups. Computer models show that only one or very few animals are needed …

Understanding how groups of individuals with different motives come to daily decisions
about the exploitation of their environment is a key question in animal behaviour. While …

Leadership is commonly invoked when accounting for the coordination of group movements
in animals, yet it remains loosely defined. In parallel, there is increased evidence of the …

In species that move in cohesive groups, animals generally reach decisions through socially
distributed processes, and individual knowledge is expected to influence collective decision …

In animal groups, collective movements emerge from individual interactions. Biologists seek
to identify how characteristics of actors in these groups, and their relationships, influence the …

For animal species that forage as cohesive units, communal decisions about when to forage
and where to go are necessary to maintain group cohesion. While in some species …

We addressed decision‐making processes in the collective movements of two groups of
Przewalski horses (Equus ferus przewalskii) living in a semi free‐ranging population. We …

Groups of animals—flocks, herds, shoals, and swarms—are often dynamical entities.
Relative positions of group members change, and most groups divide and re-form on …

In animal groups, individual interactions achieve coordinated movements to maintain
cohesion. In horse harem groups, herding is a behavior in which males chase females from …

Elucidating whether common general mechanisms govern collective movements in a wide
range of species is a central issue in the study of social behaviour. In this paper, we describe …
