| Abstract: | The influence of relatedness on male–male aggression was tested in three‐spined sticklebacks Gasterosteus aculeatus. The intensity of aggression against brothers and non‐kin males did not differ significantly, indicating that kin recognition plays at most a minor role in aggressive interactions between male G. aculeatus. |
