Protected areas mitigate human-induced nocturnal shifts in large mammal communities in Southwest China

Nocturnality of 29 mammal detections from 1897 camera traps within the Camera-trapping Network for the Mountains of Southwest China and corresponding environmental variables.Species: common name for detected speciesPA_ID: ID of the protected areas where the species is detectedDate: date of the detectionTime: clock time of the detectionsunTime: relative solar time of the detectionNocturnality: nocturnality index of the detectionHM: human modification index at the camera locationPA: whether the camera is located inside (PA = 1) or outside (PA = 0) PAsPA_HM: interaction term between PA and HMJulianDate & JulianDate2: count of consecutive days since the start of each year and its quadratic termLST: land surface temperatureELE: elevation

本数据集涵盖中国西南山地红外相机监测网络（Camera-trapping Network for the Mountains of Southwest China）内189台红外相机（camera traps）获取的29次哺乳动物观测记录及其配套环境变量，各字段说明如下：
Species: 观测物种的通用名称
PA_ID: 该观测记录所在保护区的编号
Date: 观测拍摄日期
Time: 观测拍摄的时钟时刻
sunTime: 该观测记录对应的相对太阳时
Nocturnality: 该观测记录的夜行性指数
HM: 人类活动改造指数（HM），即相机布设点位的人类活动改造程度
PA: 保护区内标识（PA），相机布设于保护区内时取值为1，设于保护区外时取值为0
