本研究的目的是 (i) 研究普通蟾蜍 bufo (L.) 对潜在自然捕食者的反应，以及 (ii) 在虚拟实验中分析适当的敌人关键刺激。 (i) 普通蟾蜍的潜在天敌生活在地面（刺猬、巨蚁、环蛇）、空中（猫头鹰、秃鹰、蝇绿蝇）和水中（水蛭）。 （ii）在蟾蜍和潜在捕食者之间的对抗过程中，事实证明，蟾蜍的关键刺激“敌人”并不是一个独特的模式。捕食者的关键特征由各种刺激参数组成，例如（1）运动速度，（2）运动方向，（3）刺激背景对比度的方向，（4）刺激面积，（5）运动刺激的配置。 （iii）移动视觉刺激的特定配置参数在蟾蜍和环蛇的猎物-捕食者关系中起主导作用。蟾蜍自然移动的蛇释放僵腿回避姿势的特点可以用一个相对简单的假人来表示。
The aim of the present investigation was (i) to study the behaviour of the Common Toad Bufo bufo (L.) in response to potential natural predators and (ii) to analyze appropriate enemy key stimuli in dummy experiments. (i) Potential predators of Common Toads live on the ground (hedgehogs, giant ants, ringsnakeks), in the air (owls, buzzards, fly Lucilia bufonivora), in the water (leeches). (ii) During confrontations between toad and potential predators it turned out that the key stimulus "enemy" for the toad is not a unique pattern. Key features of predators consist of a variety of stimulus parameters, such as (1) movement velocity, (2) direction of movement, (3) direction of stimulus background contrast, (4) stimulus area, (5) configuration of a moving stimulus. (iii) Particular configurational parameters of a moving visual stimulus play a dominant role in the prey-predator relation of toad and ringsnake. The characteristics of the natural moving snake releasing stiff-legged avoidance posture in the toad can be represented by a relatively simple dummy.
