About phenotypic variability of taimyr tundra wild reindeer (Rangifer Tarandus)

Abstract

Seasonal migratory movements (branches) of certain groups of Taimyr tundra reindeer were examined on 6 local stationary parts of the area Taimyr population of wild reindeer (South West Taimyr, on the border of West and Central Taimyr) in 2001-2010 to identify the phenotypic variability of species. In the eastern part of the peninsula collection of material in this direction was carried out by questionnaires and digital certificates volunteers (District River valley Khatanga, lower reaches of the river Kotui). Over 10 years of research at the Taimyr tundra reindeer in the West Taimyr three mass phenotype (tareysky and two connecting the Yenisei), one small numerical (purinsky) and one very rare were identified (found only among females by a single observation on average in r. Pyasina). In the south eastern Taimyr one phenotype identified from digital images (East Taimyr, lower reaches of the river. Kotui), phenotypically not similar to all western Taimyr options. It is also in the process of studies have confirmed that animals with a tareysky phenotype seasonally migrate first to the Central Taimyr (area r. Dudypta), then they followed in the river valley Khatanga. Herds of deer Yenisei phenotypes migrate to Putorana; deer with the East Taimyr phenotype leave for wintering grounds in the northern part of the boreal Evenkia.
