Mixed-phenotype grouping: the interaction between oddity and crypsis (2012)
Journal Article
Rodgers, G. M., Kimbell, H., & Morrell, L. J. (2013). Mixed-phenotype grouping: the interaction between oddity and crypsis. Oecologia, 172(1), 59-68. https://doi.org/10.1007/s00442-012-2473-y

Aggregations of different-looking animals are frequently seen in nature, despite well-documented selection pressures on individuals to maintain phenotypically homogenous groups. Two well-known theories, the ‘confusion effect’ (reduced ability of a pr... Read More about Mixed-phenotype grouping: the interaction between oddity and crypsis.

Olfactory cue use by three-spined sticklebacks foraging in turbid water: prey detection or prey location? (2012)
Journal Article
Johannesen, A., Dunn, A. M., & Morrell, L. J. (2012). Olfactory cue use by three-spined sticklebacks foraging in turbid water: prey detection or prey location?. Animal behaviour, 84(1), 151-158. https://doi.org/10.1016/j.anbehav.2012.04.024

Foraging, when senses are limited to olfaction, is composed of two distinct stages: the detection of prey and the location of prey. While specialist olfactory foragers are able to locate prey using olfactory cues alone, this may not be the case for f...

Artificial enhancement of an extended phenotype signal increases investment in courtship by three-spined sticklebacks (2012)
Journal Article
Morrell, L. J., Hentley, W. T., Wickens, V. J., Wickens, J. B., & Rodgers, G. M. (2012). Artificial enhancement of an extended phenotype signal increases investment in courtship by three-spined sticklebacks. Animal behaviour, 84(1), 93-101. https://doi.org/10.1016/j.anbehav.2012.04.013

Interactions between the components of a multiple-signal sexual display can be complex, and previous work has shown that alteration of one component can lead to changed investment in either the altered or other display components. Extended phenotype... Read More about Artificial enhancement of an extended phenotype signal increases investment in courtship by three-spined sticklebacks.

Consistency of leadership in shoals of mosquitofish (Gambusia holbrooki) in novel and in familiar environments (2012)
Journal Article
Burns, A. L. J., Herbert-Read, J. E., Morrell, L. J., & Ward, A. J. W. (2012). Consistency of leadership in shoals of mosquitofish (Gambusia holbrooki) in novel and in familiar environments. PLoS ONE, 7(5), 1-6. https://doi.org/10.1371/journal.pone.0036567

In social animal groups, an individual's spatial position is a major determinant of both predation risk and foraging rewards. Additionally, the occupation of positions in the front of moving groups is generally assumed to correlate with the initiatio...

Social network correlates of food availability in an endangered population of killer whales, Orcinus orca (2012)
Journal Article
Foster, E. A., Franks, D. W., Morrell, L., Balcomb, K. C., Parsons, K. M., van Ginneken, A., & Croft, D. P. (2012). Social network correlates of food availability in an endangered population of killer whales, Orcinus orca. Animal behaviour, 83(3), 731-736. https://doi.org/10.1016/j.anbehav.2011.12.021

For the majority of social species, group composition is dynamic, and individuals are interconnected in a heterogeneous social network. Social network structure has far-reaching implications for the ecology of individuals and populations. However, we...
