Patterns of the reindeer (Taimyr-Evenk population) movement in dynamics during migration

Despite the keen interest in reindeer, a number of issues in its ecology are still poorly understood. Difficulties in assessing the state of deer populations are associated with technical difficulties, the need to track individuals in the wild. In addition, most of the year they are in motion, passing from 6.5 to 9 thousand km 2 . To assess and predict the state of populations, information is needed not only about the number, but also about the physiological state of individuals. This work is devoted to the development of indirect methods for assessing the state of reindeer based on the indicators of the migration activity of individual individuals. The use of collars with radio transmitters makes it possible to assess in detail the peculiarities of animal movement modes using numerous indicators describing the relationship between movement speed on different days. This opens up the possibility of using data to understand the state of individuals, which, ultimately, makes it possible to assess the dynamics of the abundance and stability of wild reindeer populations in general.
