Abstract

Animal personality is defined as behavior that is consistent across time and context. Ecological and evolutionary pressures might exert sexually dimorphic effects on personality traits. In this study, variations in docility and exploratory behaviors of male and female plateau zokor (Eospalax baileyi) in two populations from different geographical sites were quantified during their breeding season, using bag and open field test. We observed significant repeatability of behaviors in the bag and open field test, except for sniffing behavior in zokors from TZ site. We found that sex influences the personality traits of plateau zokors more than geographical variation in both the bag and open field test. Females had a higher docility than males in the bag test. The findings of this study emphasize the importance of considering plateau zokors’ sex and personality traits when assessing their fitness, behavior, or suitability for behavioral future research work.

地下环境增加了高原鼢鼠雌雄人格特征的分化
动物的个性被定义为在不同时间和环境下保持一致的行为。生态和进化压力可能对人格特征产生两性二态效应。本研究采用袋试验和野外试验的方法,对高原鼢鼠(Eospalax baileyi)两个不同地理地点种群的温顺性和探索行为的变化进行了定量分析。我们观察到除TZ地点的动物嗅探行为外,袋内和野外试验的行为具有显著的重复性。结果表明,性别对高原鼢鼠人格特征的影响大于地理差异。在袋子试验中,雌性比雄性更温顺。这项研究的结果强调了在评估高原鼢鼠的适应性、行为或对未来行为研究工作的适应性时,考虑其性别和人格特征的重要性。

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
