| 摘 要： | 2010年7～9月,利用焦点动物取样法并结合全事件取样法对东北林蛙的捕食行为研究表明：对运动敏感的视觉特性对东北林蛙的捕食行为有重要影响,其所能捕获的对象均为移动物体;东北林蛙整个捕食行为存在多种模式和环节,分别由相应条件触发;猎物的形状、运动方向和活动性的强弱均影响东北林蛙的捕食行为;相对于移动的目标,振动和闪动的目标更容易引起东北林蛙的捕食;东北林蛙对猎物运动的敏感度较高,但处理食物能力较弱。

| Abstract: | The predatory behavior of Rana dybowskii are study by field observation and laboratory testing.The results showed that the predatory behaviors of Rana dybowskii are influenced by it's optical characteristic,all the objects which they can capture are moving objects;the whole progress of the predatory behavior has multiform modes and steps,which are triggered by relevant conditions;the shapes,the direction of movement and the intensity of movement of the prey influence the predatory behaviors of Rana dybowski... |
