Abstract
This article discusses the features of Apis mellifera mellifera associated with the expansion of their habitat to the north. The A. m. mellifera
 isolated in Kama Urals is considered the Prikamsky honeybee population 
and has retained the features of a pure gene pool. Here, we analysed the
 biological and physiological features of bees native to Kama Urals and 
the crossbreeding that occurs among these bee species.

Introduction
Before the anthropogenic period, a Euro-Siberian sub-species of the honeybee, the Central Russian dark hylile bee (Apis mellifera mellifera L.), spread naturally over a large area from southern France to Siberia, reaching as far north as 60°N latitude ( Ruttner et al, 1990).
 This area expanded as the species moved north due to complex 
ethological and physiological adaptations to the cold climate zone ( Eskov, 1995).
The
 Cis-Ural region is the territory located on the western slope of the 
Ural Mountains on the outskirts of the East European Plain. The 
territory lies in the basins of the Kama and Pechora Rivers and includes
 the Pechora lowlands to the north and the Verkhnekamskaya 
Bugulma-Belebey upland to the south. In the Cis-Ural region in Kama 
basin, the Kama Cis-Ural territory predominates. The northern region of 
the Kama Cis-Ural territory is a typical middle taiga consisting of 
spruce-fir forests, pine forests and peat bogs. The central region of 
the territory is southern taiga that includes spruce-fir forests with an
 admixture of linden. In the southern region of the territory, there is a
 subzone of mixed forests. The southeast is occupied with Kungursky 
forest steppe with typical degraded chernozems. Northeast of the Kama 
Cis-Ural territory is a dark coniferous mountain taiga with bald peaks 
standing high above the taiga (Grigoriev, 1962).
Central Russian bees (A. m. mellifera)
 have been historically developed in natural biological communities on 
the Kama Cis-Ural territory. This finding was recorded by  Mikhailov (1927) and  Alpatov (1948).
 According to studies conducted by researchers in the Zoology Department
 of Perm Pedagogical University, Central Russian bees overwhelmingly 
dominated the Perm Territory previously. However, from the 1950s 
onwards, agricultural workers have been importing the queens and bee 
packages of southern races that were not adapted to the harsh conditions
 of the north area. The importation of these southern bees with the 
purpose of increasing productivity resulted if the emergence of hybrids 
of unknown origin. By the 1980s, cross-breeding of bees had reached 40% 
in some apiaries causing increased morbidity and the withdrawal of bee 
colonies in the winter. This process was aggravated by the mite Varroa
 destructor affect. To a lesser extent, the cross-breeding of bees 
influenced the Uinsky and Krasnovishersky areas, which had been declared
 as pure breeding areas of the Central Russian bees. The recruitment of 
honeybee populations in natural conditions (wild hive, hollows of trees,
 rocks, and other shelters) is performed because the bees disperse 
during swarming. In the late 20th century, a negative impact on the gene
 pool of the Central Russian bees caused by the introduced bees was 
observed. The conservation of the gene pool of Central Russian bees and 
the preservation of the indigenous forms of local Central Russian bee 
populations have been discussed in many publications ( Grankin, 1998 and Kryvtsov, 2008).
Materials and Methods
Studies
 performed by Perm researchers on bee colonies (1990–2000 Gg.) in the 
Kama Cis-Ural territory distinguished a population of honey bees of the 
Central Russian race that had the features of a pure gene pool based on 
physiological, morphological (Petukhov, 1996 and Shurakov et al., 1999) and genetic (Ilyasov et al, 2006)
 indicators. These bees are named “Prikamsky” after the territory where 
they were detected. The Prikamskaya population formed naturally in the 
northern area and has a particular value today, as it is the natural 
reserve of the pure gene pool of Central Russian bees. Currently, in the
 Kama Cis-Ural territory, two groups of native bees of the Central 
Russian Prikamskaya population have been identified. They are separated 
from each other by a distance of 300 km. The Uinskaya group exists in 
the southeast of the Perm region, and the Visherskaya group exists in 
the north of the Perm region, which is the northern boundary of the 
honeybee, (Petukhov, 1996 and Ilyasov et al., 2006) (Fig. 1).
