“…At the same time several chlorophyll fluorescence studies have already documented both adverse effects of UV-B (e.g. Bjerke et al, 2005;Garty et al, 2004;) and that lichens could be extremely resistant (e.g. Sancho et al, 2007).…”

Abstract:Research into and diagnosis of environmental change prior to the introduction of bioindicator methods were linked primarily to apparatus. Drawing attention to the reactions of organisms sensitive to that change and using them in environmental quality control have opened new opportunities for development of a new scientific discipline, known in the literature as bioindication. Bioindication combines several scientific disciplines, including biology, broadly conceived geography, and chemistry. It thus combines in a comprehensible manner apparatus-derived measurements (chemical analysis results) and areas of bioindicator exposure (situation and distance from the emitter), translating these parameters into bioindicators' anatomical and morphological reactions. The development of bioindicator methods progresses rapidly, and -as is usually the case under such circumstances -it is difficult to ensure that they are transparent and that no chaos ensues. In view of the above, it seems necessary to embark on a discussion of these issues and consider compiling lists of most applicable indicator organisms for examination of particular environmental toxins in particular environments.

The aim of this study was to identify, in the lichen Ramalina lacera, antioxidants that could provide indications of air pollution stress, and respond earlier than traditionally used structural/physiological parameters. The pollution-sensitive lichen R. lacera was transplanted from its relatively unpolluted natural habitat to two air-polluted sites for a period of up to 6 months. The superoxide dismutase and catalase activities, total water- and lipid-soluble low-molecular-weight antioxidant capacities and chlorophyll b/chlorophyll a ratios were assessed every 6 weeks. The earliest signs of oxidative stress were detected in the activities of fungal copper/zinc-superoxide dismutase, algal iron-superoxide dismutase and water-soluble low-molecular-weight antioxidants, which increased significantly as early as 42 days after exposure to pollution. Catalase activity increased in lichens transplanted to the polluted sites after 90 days. All activities decreased towards the end of the experiment. The impact of air pollution on R. lacera, using the traditionally employed parameter of chlorophyll b/chlorophyll a ratio, was only detected after 6 months of exposure to air pollution. Our results indicate that antioxidant parameters may serve as improved early-warning indicators of air pollution stress in lichens.
