ResearchThe primary goal of our research is to determine how the distribution of resources in space and time influences the aggressiveness of animals. In laboratory and field experiments, we manipulate presentation of food or mates, while monitoring the aggressive behaviour of small groups of fish or birds. Our long-term goal is to develop general principles of competitive aggression that will help explain the diversity of foraging, mating and social systems observed in the wild.QCBS students Jean-Michel MattePh.D.  Shannon ClarkeM.Sc.
