Factors of the Range Expansion of the Maral (Cervus elaphus sibiricus Severtzov, 1873) (Artiodactyla; Cervidae) in the South of Evenkia

The presented work considers the population of the maral (Cervus elaphus sibiricus Severtzov, 1873) as a species naturalized in the middle reaches of the Podkamennaya Tunguska River, on the territory of the Tunguska State Nature Reserve. For the first time, successful settlement and naturalization of maral in the middle taiga forests of the south of Evenkia, which began in 2018–2019, was described. The climatic, biological and anthropogenic factors of the expansion of its range were considered. In this area, the average annual air temperature has so far remained below the temperature regime typical of most of the maral’s range within Krasnoyarsk krai. This is evidence in favor of the hypothesis of an indirect influence of climatic changes that manifested themselves in the north of Central Siberia on the settlement of the maral. The most likely decisive factor in the red deer’s northward movement is anthropogenic impact, which resulted in an increase in the number of feeding stations and the anxiety factor in the native range.
