Аннотация: The abundance distribution of different ecological groups of lichens depending on bark pH has been studied on 1- to 24-year shoots of Siberian fir in the mountains of southern Siberia. Along with acidophytic lichens commonly found on the Siberian fir (Usnea sp., Bryoria sp., etc.), its young shoots are also colonized by nitrophyticПоказать полностьюspecies (Physcia tenella, Melanelia exasperatula, etc.), which is evidence for the increasing pH of shoot bark. The proportion of thalli of nitrophytic lichen species shows a significant positive correlation with the pH of the upper (dusted) bark layer and is greater in the Eastern Sayan (at bark pH averaging 5.4) than in the Western Sayan (pH 4.7). The trends revealed in this study may be used for indication of pollution and ecological monitoring of forest ecosystems.
