Optimal individual positions within animal groups (2008)
Journal Article
Morrell, L., & Romey, W. L. (2008). Optimal individual positions within animal groups. Behavioral ecology, 19(4), 909-919. https://doi.org/10.1093/beheco/arn050

Animal groups are highly variable in their spatial structure, and individual fitness is strongly associated with the spatial position of an animal within a group. Predation risk and food gains are often higher at the group peripheries; thus, animals... Read More about Optimal individual positions within animal groups.
