Collective decision-making in baboons (previous work)
To stay together, animal groups on the move must come to a consensus about where and when to go, despite the fact that individual preferences may often conflict. Resolving these conflicts effectively is essential for animals that live in stable, socially-complex societies, such as baboons. How are these movement decisions reached?
To address this question, my collaborators (including Meg Crofoot, Damien Farine, and Iain Couzin) and I used GPS tracking data on the movements of the majority of baboons within a single troop, a 3-dimensional map of their environment, and quantitative analyses to tease apart the different influences on baboon movement.
Above is an example of baboon collective movement. Each dot represents a single baboon within the troop.
How shared or unshared are baboons' decisions about where to move?

Group spatial organization
Do individuals occupy particular spatial positions within the group, and if so how do they maintain those positions?
Habitat influences on collective movement
How do individual baboons integrate habitat and social information when making movement decisions?
How does habitat structure affect group structure and movement at the collective level?
