- Abstract:
- In this project I will generate a body of evidence-based theory about individual variation in group-living animals. Group-living animals are extremely important to the functioning of the world's ecosystems, but a crucial aspect of groups - that individuals are very variable in behaviour and appearance - has not been thoroughly studied. The natural world abounds with animals associating in groups, which can be as transient as flocks of birds, as persistent as the perennial colonies of ants, or somewhere in between, such as teams of people in engaged in business enterprise. The behaviour of individuals cooperating in groups combines in complex ways to form the collective behaviour of the group. Evidence is accumulating that, even when individual group members superficially appear similar, such as in honeybees, they are in fact highly variable. For example, honeybees vary in their readiness to perform different tasks. It is clear that such variation must be useful, otherwise natural selection should have eliminated it. Our current understanding of consistent individual differences in behaviour ("personality") is based on models of unrelated individuals competing over resources. In fact, personality in humans and other animals often develops whilst they grow-up in groups. The first part of this project will involve the construction of mathematical models that will help us to understand how personality develops in group-living animals, whether through individual differences in body morphology or in the development of behaviour. I will test these models by examining published data on the development of individual variation in groups of juvenile animals such as tadpoles, caterpillars and birds. In the second part of the project I will identify how ecological factors influence the extent of specialisation. Variation enables some individuals to be specialists at particular tasks, either because they develop the specialised morphology (e.g. the jaws of soldier ants) or become highly skilled in that task (e.g. the flower handling of foraging bees). However, too much specialisation reduces group flexibility, in which case, if conditions change, the group may perform certain tasks poorly. I will construct models to make predictions about how individual variation should be affected by factors such as task number, environmental changeability, group size, and relatedness amongst group members. This body of work will unite currently separate studies of persistent groups of related individuals (e.g. army ants) on the one hand and transient groups of unrelated individuals (e.g. foraging fish) on the other. I will test these models using data on variation among workers of social bees, ants and wasps. I concentrate on this group because of their importance in the world's ecosystems and their highly sophisticated collective behaviour. Next, I will construct some more specific models of certain types of variation in social insect workers, in body size, learning, and how they collect food. These models will enable some very clear predictions that can be easily tested. I will then synthesize my work on animal groups with the extensive literature on the development of personality in children and variation among human groups in businesses. This will help us understand both how the development of personality is affected by group membership such as school classes, and how the mixture of personalities influences the effectiveness of group performance in business. Thus my work will have implications for how society cares for children and how businesses should manage their employees to increase effectiveness, as well as inspiring the future study of personality in humans and other animals.
