“…This technique requires less lichenological expertise and field time than methods based on community surveys (e.g. van Haluwyn & van Herk 2002; Will-Wolf et al . 2015), making it a potentially cost-effective option for high-volume, large-scale inventories.…”

It is generally assumed that rigorous protocols for collecting and preparing lichens are necessary to ensure accurate data, given the known limitations of the technique (Markert et al 1999; Bargagli & Mikhailova 2002;Forbes et al 2015).…”

Lichen element content is a reliable indicator for relative air pollution load in research and monitoring programmes requiring both efficiency and representation of many sites. We tested the value of costly rigorous field and handling protocols for sample element analysis using five lichen species. No relaxation of rigour was supported; four relaxed protocols generated data significantly different from rigorous protocols for many of the 20 validated elements. Minimally restrictive site selection criteria gave quality data from 86% of 81 permanent plots in northern Midwest USA; more restrictive criteria would likely reduce indicator reliability. Use of trained non-specialist field collectors was supported when target species choice considers the lichen community context. Evernia mesomorpha, Flavoparmelia caperata and Physcia aipolia/stellaris were successful target species. Non-specialists were less successful at distinguishing Parmelia sulcata and Punctelia rudecta from lookalikes, leading to few samples and some poor quality data.

“…Types of different levels of tolerance are expected to stand out as indicators. A wide range of different sensitivities has been established and single species, as well as combinations of species, have appeared to work well as bioindicators for monitoring the effects of air pollution (Van Haluwyn and Van Herk 2002). In multivariate analysis, species scores in an ordination diagram supply a measure of species sensitivity to air pollution.…”

The subject of this paper is the possibility of using self-organizing map (SOM) in the biomonitoring studies. We used lichens as biomonitors to indicate different degrees of air quality. This research included all of 88 lichen species that was collected at 75 investigated points. These lichen species showed the different responses to air pollution. The air quality was assessed by IAP (index of atmospheric pollution) values. The IAP values were calculated for all of investigated points on the territory of four natural and one urban ecosystem. Calculated IAP values were in range of 10 to 75. On the basis of the lichen data and IAP values, we have employed SOM analysis that distinguished three clusters (A, B, and C). It presented lichen indicator species for each cluster: 16 species for cluster A, 18 species for cluster B, and two species for cluster C. This paper presents a useful method to find indicator species.

“…The relative sensitivity of lichens to various contaminants, such as sulphur dioxide, heavy metals, radionuclides and organic impurities, depends on fungal biology and the nature of photosynthesis contributors (Beck 1999 ; Nimis et al 2002 ; Guschina and Harwood 2006 ). Contamination usually leads to a decrease in biodiversity and impoverishment of lichen biota (van Haluwyn and van Herk 2002 ; Sujetovienė 2015 ), but several tolerant or insensitive species, benefitting from a low level of competition, frequently increase in abundance (Nash and Gries, 1991 ; Wolseley et al 2006 ; Rola and Osyczka, 2014 ; Rola et al 2014 , 2015 ). Local environmental conditions, such as insolation, humidity and thermal fluctuations, as well as various kinds of anthropogenic stressors, often modify the organisation and structure of lichen thalli (Pintado et al 1997 ).…”

Phenotypic traits of lichens can be greatly modified by environmental factors. Granulose thalli on soil and podetia, densely covered with granules, referring to common and widespread lichen Cladonia cervicornis subsp. verticillata were found near zinc smelter. The granules are stratified, filled with fungal medulla and heavily encrusted with calcium oxalate weddellite crystals, not observed on regularly developed thalli of the species. Phylogenetic analysis revealed that deformed granulose forms belong to this taxon, showing that the phenotypic plasticity of the lichens of Cladonia can lead to the emergence of features that do not coincide with the taxonomic definition of the species. The heavy-metal accumulation capacity of both granulose and regular form of primary and secondary lichen thallus, in relation to the element content in corresponding substrate, was determined. Granulose-modified thalli accumulate greater amounts of heavy metals than regular ones, meaning that the bioaccumulation property of a given species may be greatly affected by morphological modifications. The granulose forms are also characterised by considerably higher ratios of Cd, Pb and As concentrations in lichen samples in relation to the corresponding substrates than regular ones. This means that collection of variously formed thalli should be avoided in biomonitoring sampling procedures. The results indicate that a substantial part of the element load, in particular zinc, in the examined lichen thalli collected near the smelter originates from atmospheric fallout.Electronic supplementary materialThe online version of this article (10.1007/s11356-017-0639-1) contains supplementary material, which is available to authorized users.
