Abstract
The ecology of the meadow piрit was studied in nаture in the Lower Ob region and on the Yamal Peninsula. Laboratory investigations were carried out under natural and artificial photoperiods. The factors affecting the distribution of the species in the north-eastern limit of its range were analyzed. The meadow pipit is wide-spread in the taiga zone and it does not need any special adaptations for the conditions of forest-tundra and southern tundra. But the species is not adapted to the north tundra environment. Current climate changes define the northern border of its range. The species has no obvious obstacles to spreading to the east.
