中缅树鼩社群行为的观察研究

Observational Research of Social Behavior in Tupaiabelangeri

为了探究中缅树鼩(Tupaia belangeri)的社群行为规律,对中缅树鼩的社群行为进行了观察与统计分析。采用竞技场观察了中缅树鼩的社群行为。结果表明,中缅树鼩的社群行为中,成年雌性之间的友好行为较成年雌雄个体之间增加,成年雄性之间的攻击行为较成年雌雄个体之间增加。大多数雌性树鼩会选择争斗中占优势的雄性,说明雌性在选择配偶时可能和雄性的适合度有关。雄性或雌性均能优先识别出之前与之配对的树鼩,这可能与气味识别等有关;成年雌性间的友好相处和成年雄性间攻击行为较成年雌雄个体之间增加,符合中缅树鼩单雄配偶系社会结构。

In order to clarify the social behavioral regularities in Tupaiabelangeri, the community behavior of Tupaiabelangeri was observed and analyzed. Social behavior of T. belangeriwereobserved on the arena. The results showed that the social behavior in tree shrews, adult female friendly behavior is increased between mate and temme mmwauals. the aggression behavior among adult malesis increased compared with adult male and female individuals. Most female tree shrews will opt for the dominant male in the fight, suggesting that the female may have to do with male fitness when choosing a mate. Both of males and females have the priority to identify previously matched tree shrews, which may be related to smell recognition; the relationship and aggressive behavior was increased between adult males and females, which conforms to the social structure of the males and females.
