State of epiphytic lichen communities under anthropogenic impact: Effect of abundance assessment methods on the informativity of indices

A comparative analysis has been performed on the informativity of characteristics of the state of lichen cover calculated by two methods for evaluating lichen abundance (frequency and projective cover). A close correlation of the indices obtained by the two different methods was shown, as well as th...

Description
Summary:A comparative analysis has been performed on the informativity of characteristics of the state of lichen cover calculated by two methods for evaluating lichen abundance (frequency and projective cover). A close correlation of the indices obtained by the two different methods was shown, as well as their significant association with the degree of stress, which confirms their equal usefulness in lichenoindication works. However, comparison of the informativity established that the indices based on frequency have higher resolution capability.
