title: [Concerning the problem of the northern limit of Ixodes persulcatus (Acari: Ixodidae) distribution in Karelia].
abstract: The influence of changes in climate conditions on the abundance and formation of the northern limit of Ixodes persulcatus distribution in Karelia has been studied. It has been demonstrated that the territory in which the heat provision is sufficient for the development of ixodid ticks significantly increased during 2000-2007. Thus, it favored an increase in the abundance and enhanced distribution of I. persulcatus.
