在许多领土动物中，对同种动物表现出的攻击程度取决于它们构成的威胁的大小和/或它们的熟悉程度。我们进行了水族馆实验，以调查是否领土慈鲷鱼Julidochromis transcriptus具有上下文依赖的激动反应，邻近的同种。领土持有男性的攻击率下降对邻居男性在相邻的水族馆随着时间的推移，但增加时，陌生人男性取代邻居在同一水族馆，表明男性显示“亲爱的敌人效应”对熟悉的邻居。雌性没有攻击性，天敌效应在它们之间不明显。有趣的是，占领领土的男性也增加了他们的攻击率对邻居男性转移到对面的水族馆。领土持有男性将修改他们的竞争性反应同种男性根据他们的对手的相对威胁的背景下，“正确的不正确的边界范例”。
In many territorial animals, the level of aggression exhibited toward conspecifics depends on the magnitude of the threat they pose and/or their familiarity. We conducted aquarium experiments to investigate whether the territorial cichlid fishJulidochromis transcriptushas a context-dependent agonistic response to neighbouring conspecifics. The attacking rate of territory-holding males decreased against neighbour males in an adjacent aquarium over time but increased when stranger males replaced the neighbours in the same aquarium, indicating that males displayed the ‘dear enemy effect’ toward familiar neighbours. Females were not aggressive and the dear enemy effect was not apparent among them. Interestingly, territory-holding males also increased their attacking rate against neighbour males shifted to the opposite aquarium. Territory-holding males will modify their agonistic response to conspecific males according to the relative threat of their opponents in the context of the ‘correct-incorrect boundary paradigm’.
