| 中文摘要: |
| 在围栏条件下,观测北草蜥(Takydromus septentrionalis)的交配过程,分析其行为模式,旨在建立北草蜥交配行为谱,探讨雄性交配成功率与个体特征的关系。北草蜥交配行为的一般模式为:雌雄接近→咬尾→咬腹→交媾。该行为过程的持续时间分别为0.53 m、1.77 m、0.47 m和141.3 m。所观察到的51对成功交配中,70%的配对为雄体>雌体,且雄体平均体长和体重显著大于配对雌体。雄体的交配成功率与其体长成正相关,但与头长、头宽、尾长、体重及体色均无显著相关性。 |
| 英文摘要: |
| We observed mating behavior of the Northern Grass Lizard (Takydromus septentrionalis) in an outdoor enclosure with aims to define the ethogram of mating behavior patterns and to determine the relationship between reproductive success and individual phenotypes in males.The general pattern of mating behavior in T.septentrionalis was:approaching → tail-biting → belly-biting → copulation.Duration of each behavior was 0.53 min,1.77 min,0.47 min and 141.3 min,respectively.Seventy percent of males that successfully mated were with greater mean snout-vent length and body mass than that of females.The mating success of males was positively correlated with their body size,but with their head size (length and width),tail length,body mass or skin color. |
