Dynamics of species diversity of epiphytic lichenized fungi in the Southern district of Moscow city

"The research was carried out in summer and autumn of 2006–2007 on the territory of the Southern district of Moscow city within the ambit of the Moscow ring road to collect the data about epiphytic lichen species composition and to compare them with the similar ones received in the same range in 1987–1991. On the trunks of the trees and on bushes with the height up to 2.5 m the representatives of 26 lichen species were found on at the beginning of 1990s. In 2006-2007 on the same territory the representatives of 54 epiphytic lichen species were found. The basic reason of the changes in the compositionof lichen biota revealed on the studied urban territory is eutrophication mainly nitrophication of lichen habitats in Moscow city."
