Kin-selected siblicide and cannibalism in the European earwig

  title={Kin-selected siblicide and cannibalism in the European earwig},
  author={Ralph Dobler},
Aggression levels among individuals can severely increase under high density or shortage of crucial resources, sometimes resulting in individuals killing conspecifics. This is not uncommon in family groups of diverse taxa, where the dependent offspring compete for the limited resources provided by their parents. Killing a nest mate can relax the level of competition, and cannibalism provides a direct nutritional benefit. However, nest-mate killing bears the risk of reducing indirect fitness if… CONTINUE READING
