对于领地生物来说，识别熟悉的个体可以减少侵略性遭遇的频率和强度（亲爱的敌人现象），稳定社会系统，降低领地维护成本。在这里，我们研究了蜥蜴 Liolaemus tenuis (Liolaemidae) 在熟悉和不熟悉的个体之间的竞争中表现出的行为事件，蜥蜴是一种雄性具有领地意识的物种。记录的行为包括攻击、警告、逃避和屈服，以及第一次攻击（攻击或警告）行为的潜伏期。此外，我们还评估了个体在一段时间没有社交互动后记住熟悉的同类的能力。与不熟悉的人相比，男性个体减少并延迟了针对社会熟悉的人的攻击行为。这些结果表明，雄性能够区分熟悉和不熟悉的同种雄性，并且与亲密敌人现象相一致。在熟悉和不熟悉的人之间的竞争中，其他行为也很相似。 20 天没有社交互动后，对熟悉的同类的识别就会消失。这可能与与漂浮雄性或与失去领地并随后试图争夺前邻居领地的邻居的互动有关。
For territorial organisms, recognition of familiar individuals can reduce the frequency and intensity of aggressive encounters (dear enemy phenomenon), stabilize social systems, and reduce the cost of territory maintenance. Here, we investigated the behavioural events displayed during contests between familiar and unfamiliar individuals in the lizard Liolaemus tenuis (Liolaemidae), a species in which males are territorial. The behaviours recorded were attack, warning, evasion, and submission, and the latencies to the first aggressive (attack or warning) behaviour. Additionally, we assessed the ability of individuals to remember a familiar conspecific after a period without social interaction. Individual males reduced and delayed aggressive behaviour directed towards socially familiar individuals compared with unfamiliar ones. These results suggest that males distinguished between familiar and unfamiliar conspecific males and are in agreement with the dear enemy phenomenon. Other behaviours were similar in the contests between familiar and unfamiliar individuals. Recognition of familiar conspecifics was lost after 20 d without social interactions. This may be relevant for interactions with floater males or with neighbours that lose their territory and subsequently attempt to fight for their ex-neighbour's territory.
