Monitoring of the abundance of tundra bird and mammal species encountered daily in the Hudson Bay Lowlands

The relative abundance of species is recorded as the number of individuals seen per day spent in the field by observer(s). Each observer records the animal species encountered in the field and the number of individuals observed daily. To correct for any potential biases the activities, the amount of time spent in the field and the mode of transportation of observers is taken into account. ** If data are downloaded and used for analyses, it would greatly be appreciated that the contact researcher be informed.

物种相对丰度以观察者每日野外调查所见的个体数量进行记录。每位观察者需每日记录野外观测到的动物物种及其所见个体数量。为校正观测活动中存在的潜在偏差，需将观察者的野外调查时长及交通方式纳入考量。**若下载本数据集并用于分析研究，请务必告知联络研究者，不胜感激。**
