基于行为及气味对中缅树鼩亲缘识别的研究

Study on the kin recognition of Tupaia belangeri based on behavior and odor

动物生态学研究的前提和重要内容之一是行为的辨别和分类,动物社会行为发生的首要条件是对气味信号的辨识。亲缘识别是个体产生用于识别的线索从而进行识别的过程。实验基于行为及气味对中缅树鼩的亲缘识别进行了研究,结果表明亲属与非亲属中缅树鼩的活动、休息、取食、修饰行为表现出昼夜节律性,且活动、休息、修饰行为均呈双峰型;亲属中缅树鼩的取食行为呈双峰型,而非亲属中缅树鼩呈单峰型。中缅树鼩更显著偏向于选择与其具有亲属关系动物的尿液、个体及暗盒气味。以上结果表明亲属和非亲属中缅树鼩的行为模式存在差异。此外,尿液等气味因素会对中缅树鼩的亲缘识别产生影响。

The identification and classification of behavior is one of the premises and important contents of animal ecological researches. The most important condition for animal social behavior is identification of odor signals. Kinship is the process which individuals produce clues for identification. Kin recognition of Tupaia belangeri based on behavior and odor was measured in the present study. The results showed that circadian rhythm was observed in activating, resting, feeding and grooming behavior between kin and non-kin in Tupaia belangeri , which had bimodal type in activating, resting, and grooming behavior. It showed bimodal type in feeding behavior of kin Tupaia belangeri , but unimodal type in the non-kin T. belangeri . The selection of the urine, individual and cassette odors in T. belangeri was found significantly to their relatives compared with non-kin T. belangeri . All of the results showed that there had significant differences in the behavior patterns between kin and non-kin T. belangeri . Moreover, odor factors may have an impact in the kin recognition of tree shrews, such as urine and others.
