| 摘 要： | 食虫蝙蝠依靠发射超声讯号并收听其回声来感知周围环境。Griffin(1944)将此过程命名为“回声定位”(Echolocation)。测定这种“回声定位”能力,通常都采用障碍物回避试验法(Griffin,1944,1974;Suga,1969;Jen,1980),即让蝙蝠在静止不动的细丝阵列之间飞行,记录碰撞和回避障碍物的次数,以判断蝙蝠“回声定位”能力的有无和高低。Jell与 McCarty(1978)发展了这一方法,让蝙蝠在障碍物间捕食飞行,并比较观察,发现蝙蝠能有效地回避障碍目标。了解自然界中以捕食昆虫为生的蝙蝠,在其捕食过程中,如何回避障碍物这个问题,对研究食虫蝙蝠的“回声定位”机制是有意义的。本文以鲁氏菊头蝠(Rhinolophus rouxi)为对象进行了实验研究。

| Abstract: | An obstacle-avoidance test was used to determine the avoidance ability to stationary obstacle of ten leaf-nosed bats (Rhinolophus rouxi ) . of these seven were used to test their obstacle ability during natural predation.The mean percentages are 77.07±0.86% and 85.58±1.11%, respectively. It is shown that the reaction of avoidance ability to stationary obstacles was significantly higher (P<0.001) during predation than non-predation periods. |
