“…[45] has demonstrated the protective role of parietin against Cd by producing non-protein thiol compounds (cysteine, glutathione and phytochelatines) involved in the detoxification of cadmium. Gauslaa et al [46] reported that in polluted sites, the medullary metabolites in Ramalina farinacea have been reduced and lichen is less protected. Weissman et al [47] reported that under conditions of low pollution, antioxidant activities occur in Ramalina lacera as protective mechanisms.…”

“…В настоящее время в биомониторинге состояния окружающей среды широко используют лишайники [Meysurova et al, 2014;Трифонова, Салмин, 2019]. Некоторые виды в качестве биоиндикаторов используют особенно часто -это устойчивые к антропогенному загрязнению лишайники.…”

“…Например, благодаря широкому распространению и возможности расти в условиях умеренного техногенного загрязнения эпифитный лишайник Hypogymnia physodes (L.) Nyl. стал традиционным объектом биомониторинга [Gauslaa et al, 2016;Трифонова, Салмин, 2019]. Для оценки состояния среды также используют Parmelia sulcata Taylor .…”

Рассмотрена проблема оценки индикаторной способности систематически близких видов эпифитных лишайников на основе данных об их элементном составе, получаемых с помощью атомно-эмиссионной спектрометрии с индуктивно-связанной плазмой. На примере представителей рода Hypogymnia показано, что H. tubulosa по сравнению с H. physodes обладает более высокой накопительной способностью по отношению к кальцию, железу, литию, а также к таким тяжелым металлам, как кадмий, свинец, алюминий, титан, сурьма. Однако H. tubulosa резистентен к мышьяку. Сопряженный анализ элементного состава и физиолого-биохимических характеристик близкородственных видов лишайников будет способствовать выяснению механизмов устойчивости одних видов и причин уязвимости других в условиях загрязнения среды. Это позволит расширить возможности биомониторинговых исследований и будет способствовать разработке рекомендаций по сохранению биоразнообразия и стабильности природных экосистем.

“…Moreover, lichen communities growing in metal-rich ultramafic alpine areas may exhibit differences in terms of secondary metabolite production compared to those of adjacent non-ultramafic areas (e.g., lower frequency of species with depsidones) [45]. However, in other cases, lichen acids play no role in protection of thalli against airborne heavy metal pollutants [46] or against metals taken from a substrate [47]. Factors other than secondary metabolites may also affect metal accumulation as shown by two closely-related species containing the same lichen acid and growing in the same habitat but having dramatically different heavy metal concentrations [32].…”

Diversity of secondary lichen metabolites and their relationship to substrate and environmental parameters were studied in saxicolous lichens in the Middle and South Urals of Russia. Atranorin, usnic acid, gyrophoric acid, zeorin, norstictic acid, antraquinones and stictic acid were found in 73, 42, 41, 37, 36, 35 and 32 species, respectively, of 543 taxa collected. One hundred and ninety six species (i.e., 36% of total species documented) contained no secondary metabolites. Spectra of secondary metabolites of crustose lichens varied on different rock types, while in fruticose and foliose groups only those species without lichen acids were dependent on the substrate type. In Canonical Correspondence Analysis, secondary lichen metabolites were subdivided into groups depending on the concentration of Ca and metals in the substrate. Gyrophoric, lobaric, psoromic, rhizocarpic and stictic acids were common in crustose lichens in metal-poor habitats; species with antraquinones and lichens without any secondary metabolites were most abundant on limestone (alkalic and metal-poor), while other common lichen metabolites had no to minimal dependence on the chemistry of the substrate. The two additional abiotic factors affecting the composition of secondary metabolites were the maximum temperature of the warmest month and elevation. Our results suggest a range of possible relationships exist among lichen acids, rocks and climatic parameters. Furthermore, the same metabolite may affect both accumulation of metals and stress tolerance under unfavorable conditions.
