Fighting in fiddler crabs Uca mjoebergi: what determines duration? (2005)
Journal Article
Morrell, L. J., Backwell, P. R., & Metcalfe, N. B. (2005). Fighting in fiddler crabs Uca mjoebergi: what determines duration?. Animal behaviour, 70(3), 653-662. https://doi.org/10.1016/j.anbehav.2004.11.014

Contest duration in animals is often interpreted as being a consequence of mutual assessment of the difference in the competitors' resource-holding potential (RHP), allowing the inferior individual to avoid costly interactions it is likely to lose. D... Read More about Fighting in fiddler crabs Uca mjoebergi: what determines duration?.

Why are small males aggressive? (2005)
Journal Article
Morrell, L. J., Lindström, J., & Ruxton, G. D. (2005). Why are small males aggressive?. Proceedings of the Royal Society B: Biological Sciences, 272(1569), 1235-1241. https://doi.org/10.1098/rspb.2005.3085

Aggression is ubiquitous in the animal kingdom, whenever the interests of individuals conflict. In contests between animals, the larger opponent is often victorious. However, counter intuitively, an individual that has little chance of winning (gener... Read More about Why are small males aggressive?.

Mate guarding, male attractiveness, and paternity under social monogamy (2005)
Journal Article

Socially monogamous species vary widely in the frequency of extrapair offspring, but this is usually discussed assuming that females are free to express mate choice. Using game-theory modeling, we investigate the evolution of male mate guarding, and... Read More about Mate guarding, male attractiveness, and paternity under social monogamy.

Conservation of cancer genes in the marine invertebrate Mytilus edulis (2005)
Journal Article
