摘要

物种间的攻击会对生态和进化产生深远的影响,因为受攻击者可能会受伤、体能下降,并成为社会群体的弃儿。虽然动物会采取多种策略来避免敌对对抗,但社会影响对逃避策略的影响程度尚不清楚。在这里,我们使用计算和机器学习方法分析了小鼠(Mus musculus)混性群体自由互动时的复杂行为互动。小鼠在行为状态变化、攻击性相遇和混性互动中表现出丰富的行为。在攻击性相遇后会持续出现一个独特的行为序列,即处于顺从状态的雄性小鼠会迅速接近雌性小鼠并与之短暂互动,紧接着攻击者会与同一雌性小鼠互动。这种行为序列还与较少的肢体冲突有关。此外,雄性的行为状态可以通过行为序列的不同特征来预测,如运动学、雄性与雌性互动的潜伏期和持续时间。更广泛地说,我们的研究揭示了一种受雌性存在影响的与伦理学相关的逃避策略,它可以作为一种缓和社会冲突和防止由此导致的适应能力下降的机制。

Mice employ a bait-and-switch escape mechanism to de-escalate social conflict.

Intraspecies aggression has profound ecological and evolutionary consequences, as recipients can suffer injuries, decreases in fitness, and become outcasts from social groups. Although animals implement diverse strategies to avoid hostile confrontations, the extent to which social influences affect escape tactics is unclear. Here, we used computational and machine-learning approaches to analyze complex behavioral interactions as mixed-sex groups of mice, Mus musculus, freely interacted. Mice displayed a rich repertoire of behaviors marked by changes in behavioral state, aggressive encounters, and mixed-sex interactions. A distinctive behavioral sequence consistently occurred after aggressive encounters, where males in submissive states quickly approached and transiently interacted with females immediately before the aggressor engaged with the same female. The behavioral sequences were also associated with substantially fewer physical altercations. Furthermore, the male's behavioral state could be predicted by distinct features of the behavioral sequence, such as kinematics and the latency to and duration of male-female interactions. More broadly, our work revealed an ethologically relevant escape strategy influenced by the presence of females that may serve as a mechanism for de-escalating social conflict and preventing consequential reductions in fitness.

期刊介绍: PLOS Biology is the flagship journal of the Public Library of Science (PLOS) and focuses on publishing groundbreaking and relevant research in all areas of biological science. The journal features works at various scales, ranging from molecules to ecosystems, and also encourages interdisciplinary studies. PLOS Biology publishes articles that demonstrate exceptional significance, originality, and relevance, with a high standard of scientific rigor in methodology, reporting, and conclusions. The journal aims to advance science and serve the research community by transforming research communication to align with the research process. It offers evolving article types and policies that empower authors to share the complete story behind their scientific findings with a diverse global audience of researchers, educators, policymakers, patient advocacy groups, and the general public. PLOS Biology, along with other PLOS journals, is widely indexed by major services such as Crossref, Dimensions, DOAJ, Google Scholar, PubMed, PubMed Central, Scopus, and Web of Science. Additionally, PLOS Biology is indexed by various other services including AGRICOLA, Biological Abstracts, BIOSYS Previews, CABI CAB Abstracts, CABI Global Health, CAPES, CAS, CNKI, Embase, Journal Guide, MEDLINE, and Zoological Record, ensuring that the research content is easily accessible and discoverable by a wide range of audiences.
