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
Morrell, L. J., & Kokko, H. (2003). Adaptive strategies of territory formation. Behavioral Ecology and Sociobiology, 54(4), 385-395. https://doi.org/10.1007/s00265-003-0663-7

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.
