摘要
半自然条件下,通过直接观察及影像分析法对鳄蜥(Shinisaurus crocodilurus)的求偶和交配行为进行了研究。共记录了20种与鳄蜥求偶和交配有关的行为,其求偶和交配行为的一般模式为:(1)炫耀;(2)接近;(3)舔舐;(4)咬颈;(5)环抱;(6)交媾;(7)分离。该行为过程的持续时间分别为(157.29±33.81)s、(15.57±1.59)s、(10.86±3.05)s、(169.28±31.99)s、(66.14±16.08)s、(2 417.14±229.30)s和(26.86±9.15)s。鳄蜥的婚配制度可能是多雄多雌的婚配制,其求偶和交配模式与其近缘类群相似。
The courtship and mating behavior of Chinese Crocodile Lizard ( Shinisaurus crocodilurus ) were studied by using direct observation methods and video camera recorder in Luokeng Nature Reserve of Guangdong Province. A behavior inventory defining 20 distinctive postures/ gestures were recorded and the general pattern of courtship and mating behavior in S. crocodilurus was: (1) displaying, (2) approaching, (3) licking, (4) neck bite hold, (5) embracing, (6) copulation, (7) detaching. Duration of each behavior is 157.29 ± 33.81 s, 15.57 ± 1.59 s, 10.86 ± 3.05 s, 169.28 ± 31.99 s,66.14 ± 16.08 s,2 417.14 ± 229.30 s and 26.86 ± 9.15 s respectively. The mating system of S. crocodilurus is promiscuity possibly. The courtship and mating pattern of S. crocodilurus is similar to their affinitive relatives.
