CONTENTS
Chapter 1 General introduction
Chapter 2 Predation risk drives social complexity in cooperative breeders
Chapter 3 Spatio-temporal resource variation, group formation and the benefits of cooperative breeding in the Seychelles warbler
Chapter 4 Subordinate females in the cooperatively breeding Seychelles warbler obtain direct benefits by joining unrelated groups
Chapter 5 Predation risk mediates the benefits of sociality and
suppresses within-group conflict in a cooperatively breeding cichlid fish
Chapter 6 Experimentally induced anti-predator responses are sex specific and mediated by social and environmental factors in a cooperatively breeding passerine
