Air pollution is a global environmental problem, and its effects on human behavior, psychology, and health have been well studied. However, very few studies were done on if and how air pollution affects animal behavior, for example, social conflict. Many physiological and psychological evidences suggest a possible positive relationship between air pollution and animal social conflict, thus we established a multiple linear regression model using a captive monkey group to explore if monkeys behave more aggressively in polluted air. Our results confirmed that daily social fighting behaviors occurred more when air is polluted. Temperature has a nonlinear effect on monkey social conflict, with a fighting peak at 25-29 °C. To our knowledge, this is the first report that animal social conflict, like humans, is also affected by air pollution and temperature.
空气污染是一个全球性的环境问题，其对人类行为、心理和健康的影响已经得到了充分的研究。然而，很少有研究探讨空气污染是否以及如何影响动物的行为，例如社会冲突。许多生理和心理证据表明，空气污染与动物的社会冲突之间可能存在正相关关系，因此我们使用一个圈养猴子群体建立了一个多元线性回归模型，以探讨猴子在污染空气中是否表现出更具攻击性的行为。我们的结果证实，当空气受到污染时，猴子的日常社会争斗行为会更频繁地发生。温度对猴子的社会冲突有非线性影响，在 25-29°C 时达到争斗高峰。据我们所知，这是第一个报告表明，像人类一样，动物的社会冲突也受到空气污染和温度的影响。
