对于不是完全独居的物种，在社会隔离后，同种攻击性往往会增加，这种增加的攻击性在重新社会化后也可能被逆转。然而，关于这种攻击性可塑性的文献指的是无脊椎动物中永久的社会性或低水平的亚社会性物种。研究高水平亚社会无脊椎动物的同种攻击性可逆性，有助于加深对同种-攻击性可塑性在社会进化中的作用的理解。在这里，我们使用表现出极高水平的亚社会性的哺乳蜘蛛Toxeus Magnus，评估了三个问题。(1)其同种攻击行为是否受到社会生活和/或亲属关系的影响？结果表明，社会隔离后同种攻击性增加，而亲属关系不影响攻击性。(2)社会隔离导致的高攻击性在再社会化后能否逆转？结果表明，蜘蛛再社会化后3天，其攻击行为的增强可被逆转。(3)再社会化导致攻击可逆性的直接机制是什么？在模拟再社会化实验中，单个蜘蛛被提供了镜子，表明仅有同种蜘蛛的视觉线索就可以在6天后逆转攻击。这些结果表明，高水平的亚社会无脊椎动物在没有化学线索的情况下表现出攻击性可逆性。这更类似于永久群居物种，而不是低水平的亚社会物种，视觉线索可能对诱导攻击性改变至关重要。这些结果表明，同种攻击可逆性可能在社会进化中发挥关键作用，并可能在功能上增强物种在不同条件下的适应能力。
Conspecific aggressiveness often increases after social isolation for species that are not entirely solitary, and this increased aggression could also be reversed after resocialization. However, literature on this aggression plasticity refers to either permanently social or low-level subsocial species in invertebrates. Examinations of conspecific aggressiveness reversibility in high-level subsocial invertebrates, in which offspring cohabitate with parents for a certain period of time after sexual maturation, would enhance the understanding of the role of conspecific-aggression plasticity in social evolution. Here, using the lactating spiderToxeus magnus, which exhibits extremely high-level subsociality, we assessed three questions. (1) Is its conspecific aggression affected by social living and/or kinship? The results indicated that conspecific aggression increased after social isolation, while kinship did not affect aggressiveness. (2) Could the social-isolation-induced higher aggression be reversed after resocialization? The results showed that the increased aggression of the spiders could be reversed 3 days after resocialization. (3) What is the proximate mechanism that caused the aggression reversibility by resocialization? A simulated resocialization experiment in which single spider was provided with mirrors demonstrated that the visual cues of conspecifics alone could reverse the aggression after 6 days. These results indicate that the high-level subsocial invertebrate showed aggressiveness reversibility without chemical cues. This is more similar to permanently social species rather than to low-level subsocial species, and visual cues could be vital to induce aggression change. These results suggest that conspecific-aggression reversibility might play a key role in social evolution and may functionally enhance species’ adaptiveness under variable conditions.
