T.K. Yurkovskaya. Latitudinal differentiation of mires within the longitudinal sectors in the West of Russia // Mire Ecosystems in Northern Europe: Diversity, Dynamics, Carbon Balance, Resources and Conservation.

Analysis of the zonal structure of mire vegetation cover has been conducted within the longitudinal sectors for the first time. It was shown that sectors, recognized according to the zonal vegetation and peculiar zonal spectra, have also specific latitudinal differentiation of mires. The structure of zonality has been analyzed within three sectors of western Russia: West-Russian, East-European and West-Siberian.
Characteristic feature of latitudinal range of the West-Russian sector is the absence of the strip of polygonal mires. Incomplete spectrum of the subzonal mire types correlates fully with the absence of subzones of arctic and northern tundras. Dominating of aapa mires over raised bogs in the middle and northern taiga of this sector correlates with the predominance of pine forests over spruce forests.
The East-European and West-Siberian sectors are characterized by distinct zonality and completeness of spectra. The main difference of latitudinal differentiation of mires in these sectors is the asymmetry in zonal position of mire regional types belonging to the same class.
Each latitudinal strip is characterized by not one but several types of mires. So, the connection between mire vegetation and zonal vegetation types is not less essential in direction from the west to the east than from the north to the south, but it reveals itself on the different levels of organization of plant cover.
