Abstract
In the region of the Middle Urals copper smelting plant, in two contrast zones of atmospheric pollution we evaluated the dimensional and reproductive characteristics of the thalli of epiphytic lichen Hypogymnia physodes (L.) Nyl. and determined the concentrations of heavy metals (Cu, Fe, Cd, Zn, Pb) in them. The nonuniformity of populations both over the dimensional and reproductive characteristics and over metal content was demonstrated. The high heterogeneity of subpopulations growing on different photophytes was discovered. It is recommended to optimise data collection by taking the samples from a large number of trees (20-30) with smaller number of thalli (10-20) from one photophyte.
