PHOTOSYNTHETIC PIGMENTS OF TERRESTRIAL LICHEN SPECIES OF GENERA CLADONIA IN ROCKY FOREST COMMUNITY OF OLOVGORA (ARCHANGELSK REGION)
The content of chlorophyll a, b and carotenoids in thalli of Cladonia species from rocky forests community of Archangelsk region were analyzed. A specific feature of the environmental conditions of this lichen habitats is the impact of marine climate due to the closeness of the White Sea. The results of study of correlation between habitat conditions (altitude, slope exposition, light intensity), projective cover of species and pigments content are represented.
