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. 

Key topics:

  • Consensus decision-making

       

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?
