From hawks and doves to self-consistent games of territorial behavior (2006)
Journal Article
Kokko, H., López-Sepulcre, A., & Morrell, L. J. (2006). From hawks and doves to self-consistent games of territorial behavior. The American naturalist, 167(6), 901-912. https://doi.org/10.1086/504604

Explaining the "prior-residence effect" (automatic owner status of individuals who arrived first in an area) was one of the very first applications of game theory in animal behavior. These models, however, predict paradoxical solutions where intruder... Read More about From hawks and doves to self-consistent games of territorial behavior.

Predation risk as a driving force for sexual segregation: A cross-population comparison (2006)
Journal Article
Croft, D., Morrell, L. J., Wade, A. S., Piyapong, C., Ioannou, C. C., Dyer, J. R. G., Chapman, B. B., Wong, Y., & Krause, J. (2006). Predation risk as a driving force for sexual segregation: A cross-population comparison. The American naturalist, 167(6), 867-878. https://doi.org/10.1086/504853

Sexual segregation is widespread throughout the animal kingdom. Although a number of hypotheses have been proposed to account for observed patterns, the generality of the mechanisms remains debated. One possible reason for this is the focus on segreg... Read More about Predation risk as a driving force for sexual segregation: A cross-population comparison.

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
Kokko, H., & Morrell, L. (2005). Mate guarding, male attractiveness, and paternity under social monogamy. Behavioral ecology, 16(4), 724-731. https://doi.org/10.1093/beheco/ari050

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.

Bridging the gap between mechanistic and adaptive explanations of territory formation (2004)
Journal Article
Morrell, L. J., & Kokko, H. (2005). Bridging the gap between mechanistic and adaptive explanations of territory formation. Behavioral Ecology and Sociobiology, 57(4), 381-390. https://doi.org/10.1007/s00265-004-0859-5

How animals divide space can have fundamental implications for the population dynamics of territorial species. It has recently been proposed that space can be divided if animals tend to avoid fight locations, rather than the winner of fights gaining...

Can too strong female choice deteriorate male ornamentation? (2004)
Journal Article
Morrell, L., & Kokko, H. (2004). Can too strong female choice deteriorate male ornamentation?. Proceedings of the Royal Society B: Biological Sciences, 271(1548), 1597-1604. https://doi.org/10.1098/rspb.2004.2763

Competition for limited resources can have fundamental implications for population dynamics. However, the effects of resource depletion have rarely been discussed in the context of sexual selection, even though mate choice typically favours males who...

Are behavioural trade-offs all they seem? Counter-intuitive resolution of the conflict between two behaviours (2004)
Journal Article
Morrell, L. J. (2004). Are behavioural trade-offs all they seem? Counter-intuitive resolution of the conflict between two behaviours. Behavioral Ecology and Sociobiology, 56(6), 539-545. https://doi.org/10.1007/s00265-004-0821-6

The understanding of trade-offs between behaviours is fundamental to the study of animal behaviour. Individuals may often be faced with the choice of which of two mutually incompatible behaviours to perform. Here, I present a model investigating the...

Adaptive strategies of territory formation (2003)
Journal Article

How do territorial animals gain ownership of an area? Early modelling has considered the evolution of fighting when the winner can claim the right to the resource. Recently, alternative hypotheses have been offered where repeated interactions lead to... Read More about Adaptive strategies of territory formation.
