Fear and safety chemical cue data in crayfish

In this data, you’ll find crayfish movement data (walking speeds and times spent in different sections of the test arena) as a response to differing concentrations and types of fear cues (predatory and alarm cues) as well as differing levels of safety cues. The organization of the fear cues and safety cues in the arena were orthogonal to each other which allows a user to examine movements along each of the different stimuli levels separately or in combination. The movement of the crayfish was digitized at 1 point per second and at a single location (center of the carapace) of the animal.

本数据集包含淡水螯虾（crayfish）的运动行为数据，具体涵盖其行进速度以及在测试箱（test arena）不同区域的停留时长，该数据为淡水螯虾对不同浓度、不同类型的恐惧刺激物（捕食者刺激物与警报刺激物）以及不同强度安全刺激物的行为响应。测试箱内恐惧刺激物与安全刺激物的布局呈正交关系，使得研究者可单独或组合分析不同刺激强度梯度下的运动行为。淡水螯虾的运动轨迹以每秒1个采样点的频率，通过追踪其头胸甲（carapace）中心的单一位置完成数字化记录。
