| 中文摘要: |
| 为揭示和探讨中国大鲵(Andrias davidianus)繁殖前期的冲凉行为及其意义,在仿生态养殖环境条件下,采用定时定点观察法和全事件记录法,对雄性成鲵的冲凉行为过程及姿势进行了观察记录,并分析了冲凉行为与年龄、求偶行为、繁殖成功率之间的关系。繁殖前期雄性成鲵表现出冲凉行为,冲凉行为与求偶行为之间存在极显著的正相关,表现出求偶行为的6尾雄性成鲵有4尾成功参与了繁殖。冲凉行为可能促进了雄性成鲵精巢的发育,引发求偶行为,最终达到成功繁殖。 |
| 英文摘要: |
| We observed washing behavior and courtship behavior of male adults of Chinese Giant Salamander Andrias davidianus in the imitated natural eco-breeding environment using all occurrence recording method at fixed time and fixed location and examined the significance of washing behavior for them by analyzing the relationship between the age, courtship behavior and breeding success. The washing behavior could be divided into four stages: washing exploration, gesture adjustment, washing and walk away with seven washing posture, head washing, tail washing, trunk washing, movement washing, surround washing, adherence washing and rising-head washing. Only males over 8 years showed washing behavior and courtship behavior after washing, and an extreme positive correlation between washing and courtship behaviors were detected. Two out of three male adults exhibited courtship behavior to participate in the breeding successfully. The washing behaviors maybe enhance gonadal development and maintain breeding successfully via courtship behavior. |
