High resolution locomotor time series in Japanese quail in a home-cage environment over a 6.5 day period (#10-group 2)
收藏资源简介:
Each data point represents a 0.5s time interval (xi) in which the quail could either been ambulating (xi=1) or immobile (xi=0), over a 6.5 day period .The total number of data points is approximately 1.070.000. This time series has both a fractal pattern, as well as ultradian and circadian rhythms. <strong>This is the data from quail number 10, of the second experimental group</strong>. In this experiment in a whole, the locomotor activity of 24 adult females quail (100-140 days old) was evaluated in a home-cage environment in a white wooden box measuring 40 x 40 x 40 cm (width x length x height, respectively) with a wire mesh floor. A metal bar wall divided the box in two same-size zones (feeding, nesting), and an opening served as a door allowing the bird to move freely between compartments. A video camera that automatically switched to infrared recording after lights were turned off was suspended 1.5m above the box. It was connected to a computer in an adjacent room and could be accessed remotely by experimenters. Testing began at approximately 1:00 PM, when 12 quail were placed in a box, and transported to a nearby experimental room. Each bird was then placed individually in the feeding zone of one of the boxes. During the following 6.5 days, the birds’ locomotor activity was continuously recorded. Testing ended at 9 PM the 7th day. Daily maintenance activities (egg collection, cleaning and feeding) were performed between 12 and 12:30 PM; the activity during this period was not included in time series, which in total implied a loss of 2% from the data set. Since only 12 birds could be tested simultaneously, two consecutive groups of 12 individuals were evaluated (group 1 and group 2). We used the commercially available ANY-MAZE@ computer program to register locomotion at 0.5 s intervals (xi). The locomotor time series (1.07e6 time intervals) of each bird was obtained by assigning a number one (xi = 1) if during the interval the bird was ambulating, or a zero (xi = 0) if immobile.
每个数据点对应一段0.5秒的时间区间(xi),该区间内鹌鹑要么处于行走活动状态(xi=1),要么处于静止状态(xi=0),实验总周期为6.5天。数据集总数据点数约为1.07×10^6个。该时间序列兼具分形模式、超昼夜节律与昼夜节律。**该数据来自第二实验组的10号鹌鹑**。 本实验共评估了24只100~140日龄成年雌性鹌鹑的笼养自主活动水平。实验环境为尺寸40×40×40 cm(宽×长×高)的白色木质笼箱,底部铺设金属网格底板。箱内以金属杆分隔为两个等大区域(取食区与筑巢区),两区之间设有开口作为通道,供鹌鹑自由穿梭于两个隔间。笼箱上方1.5米处悬挂一台摄像机,灯光熄灭后可自动切换至红外录制模式。该摄像机连接至邻室的计算机,实验人员可远程调取监控录像。 实验于当日下午1点左右启动,先将12只鹌鹑转移至邻近的实验室内,随后将每只鹌鹑单独放置于一个笼箱的取食区。在接下来的6.5天内,研究人员持续记录鹌鹑的自主活动情况,直至第7天晚上9点实验结束。每日的维护工作(捡蛋、清洁笼箱与投喂饲料)均于中午12点至12点30分进行,此时间段内的活动数据未被纳入时间序列,最终导致该数据集损失约2%的有效数据。由于单次实验仅可同时测试12只鹌鹑,实验分为两组连续开展(第1组与第2组)。 本研究采用商用ANY-MAZE®计算机软件,以0.5秒为时间间隔记录鹌鹑的运动情况。通过以下规则获取每只鹌鹑的运动时间序列(共1.07×10^6个时间区间):若某一时间区间内鹌鹑处于行走活动状态,则将该区间的赋值记为1(xi=1);若处于静止状态,则赋值为0(xi=0)。
