群体间的冲突被认为是塑造动物群体社会行为进化的主要力量。一个长期存在的假设是，面临对手攻击风险的群体应该变得更有社会凝聚力，以增强适应力或防范未来的攻击。然而，凝聚力行为（如梳理或社会联系）在群体间冲突中的作用通常是不清楚的。我们进行了一项实验，我们将潮木白蚁（Zootermopsis angusticollis）的幼蚁群暴露在竞争对手的蚁群中，同时用可渗透的屏障阻止它们进行物理战斗。我们测量了接触前、接触中和接触后的社会接触、异体修饰和营养作用。与暴露前相比，白蚁在暴露对手期间的社会接触率有所上升，但在蚁群分离9天后，社会接触率又恢复到暴露前的水平。有证据表明，冲突对工人营养性有延迟效应。我们认为群体间冲突中的社会联系是一种社会监督形式，可以检查个体身份并评估群体资源持有潜力。群体间冲突可以增加短期和长期的社会凝聚力，提高群体在竞争中的效率。
Intergroup conflict has been suggested as a major force shaping the evolution of social behaviour in animal groups. A long-standing hypothesis is that groups at risk of attack by rivals should become more socially cohesive, to increase resilience or protect against future attack. However, it is usually unclear how cohesive behaviours (such as grooming or social contacts) function in intergroup conflict. We performed an experiment in which we exposed young colonies of the dampwood termite, Zootermopsis angusticollis, to a rival colony while preventing physical combat with a permeable barrier. We measured social contacts, allogrooming and trophallaxis before, during and after exposure. Termites showed elevated rates of social contacts during exposure to a rival compared to the pre-exposure phase, but rates returned to pre-exposure levels after colonies were separated for 9 days. There was evidence of a delayed effect of conflict on worker trophallaxis. We suggest that social contacts during intergroup conflict function as a form of social surveillance, to check individual identity and assess colony resource holding potential. Intergroup conflict may increase social cohesion in both the short and the long term, improving the effectiveness of groups in competition.
