Journal Article

Predation risk is often associated with group formation in prey, but recent advances in methods for analysing the social structure of animal societies make it possible to quantify the effects of risk on the complex dynamics of spatial and temporal or...

Colour change and assortment in the western rainbowfish (2010)
Journal Article
Rodgers, G. M., Kelley, J. L., & Morrell, L. J. (2010). Colour change and assortment in the western rainbowfish. Animal behaviour, 79(5), 1025-1030. https://doi.org/10.1016/j.anbehav.2010.01.017

Grouping behaviour is widespread across the animal kingdom, and is known to reduce an individual's risk of predation, for example through predator confusion. Theory predicts that individuals that are different in appearance to the rest of the group a... Read More about Colour change and assortment in the western rainbowfish.

Association patterns and foraging behaviour in natural and artificial guppy shoals (2008)
Journal Article
Morrell, L. J., Croft, D. P., Dyer, J. R. G., Chapman, B. B., Kelley, J. L., Laland, K. N., & Krause, J. (2008). Association patterns and foraging behaviour in natural and artificial guppy shoals. Animal behaviour, 76(3), 855-864. https://doi.org/10.1016/j.anbehav.2008.02.015

Animal groups are often nonrandom assemblages of individuals that tend to be assorted by factors such as sex, body size, relatedness and familiarity. Laboratory studies using fish have shown that familiarity among shoal members confers a number of be...

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.
