摘 要 ：2007年4月，利用红外线摄像设备记录人工环境下的棘胸蛙行为活动，采用扫描取样法和目标动物取样法对录像资料进行分析，对人工环境下棘胸蛙的个体行为和活动节律进行了研究。结果表明:人工环境下的棘胸蛙行为主要包括静止行为（休息、对视）；社会行为（打斗、追逐）；运动行为（游泳、鸣叫、跳跃）；捕食行为；繁殖行为（求偶鸣唱、侵占、驱赶、撕咬，摔跤、抱对、错抱、拒绝行为、产卵）等。日变化规律变化表明:棘胸蛙的静止行为占了多数，其余多数行为集中在夜间，在凌晨03:00~05:00间出现一个最高峰，与此不同的是棘胸蛙的打斗行为在白天06:00~07:00、08:00~09:00、11:00~12:00多次出现高峰，而在夜间17:00~24:00打斗行为时间分配很少。鸣叫行为在06:00~07:00，13:00~14:00出现两个高峰，而在夜间17:00~01:00鸣叫行为时间分配很少。棘胸蛙的繁殖行为也主要发生在夜间，在凌晨02:30~04:30为高峰，其间抱对行为占到67%，其次为摔跤17%，撕咬15%，而其余所占很少。在行为描述的基础上，对棘胸蛙的有关行为机制进行了探讨。

Abstract:We recorded behaviors of captive Paa spinosa using an infrared video camera, and analyzed the ethogram and activity rhythm of the frog with focal and scan sampling methods. The behaviors included stillness behavior (resting, staring), social behavior (fighting, chasing), playing behavior (swimming, calling, jumping), feeding behavior (foraging), and reproductive behavior (advertisement call, aggression, dislodge, bite, wrestle, amplexus, amplexus error, reject, oviposition). The frogs mainly kept still during the day time, but were active in the evening with a peak at the time of 03: 00-05: 00. There were three peaks of fighting behavior in the daytime: 06: 00-07: 00, 08: 00-09: 00, and 11: 00-12: 00, by contrast, fighting seldom appeared in the evening from 17: 00 to 24:00. Calling mainly appeared at 06: 00-07: 00, and 13: 00- 14: 00 in the day time, but little in the evening from 17: 00 to 24: 00. The reproductive behavior of Paa spinosa always took place in the evening, peaking at 17: 00-01: 00. The time budget of reproductive behavior was as following: amplexus(67%), wrestle(17%), and bites(15%). Based on the description of behavior, we also discussed the mechanism of behaviors. The changes of food resources, space and habitats had significant impacts on the behavior of captive P. spinosa.
