Mathematical modelling and large-scale online experiments revealed that learning from others can induce 'smarter' decisions even when most individuals are biased towards adverse risk aversion.

For baboons on the move, habitat features across multiple spatial scales combine with social interactions to impact the movements of individuals, ultimately shaping the structure of the whole group.

Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

Ants employ a new kind of trail to resolve group-level navigational difficulties in scenarios where the information available to individuals does not suffice.

Rather than complex decisions, it is the motion of individuals that allows for collective foraging regulation in ant colonies.

Detailed tracking of live predators attacking live schools of prey reveals the crucial interplay between predator attack strategy and prey behaviour and positioning in determining the predation risk within mobile animal groups.

The two-way coupling between collective actions and risk is essential to avoid the tragedy of the commons.

A standard for complex mouse behavior that can be successfully reproduced across laboratories, along with open-access data and tools to implement provide a resource for reproducibility through collaborative open-science approaches.

Ephemeral leadership between differently experienced birds regulates the balance between exploration and exploitation over successive homing flights in a manner that facilitates the accumulation of route innovations.
