title: Cain and Abel reloaded? Kin recognition and male-male aggression in three-spined sticklebacks Gasterosteus aculeatus L.
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.
