“…Taking into account that Calvatia candida and Battarrea phalloides Table 2 data indicate that Ca content in Artemisia lerchiana, Calvatia candida and Battarrea phalloides are 11.8 and 31.9 times lower, respectively, than Ca level in lichen. Lichen Ca coating in the form of Ca oxalate crystals in dry habitats can be facilitated by the abundance of Ca in the substrate [16] and is supposed to contribute to water conservation in thalli [17,18]. In this respect, Ca hyperaccumulation in D. ocellatus may be considered as a specific form of protection against active oxygen forms and UV radiation excess [19][20][21].…”

Natural reserves play a fundamental role in maintaining flora and fauna biodiversity, but the biochemical characteristics of such ecosystems have been studied in an extremely fragmentary way. For the first time, mineral composition and antioxidant status of three systematic groups of organisms, lichens (Diplischistes ocellatus), mushrooms (Calvatia candida and Battarrea phalloides) and wormwood (Artemisia lerchiana) have been described at the territory of Bogdinsko-Baskunchak Nature Reserve (Astrakhan region, Russia), characterized by high salinity and solar radiation, and water deficiency. Through ICP-MS, it was determined that scale lichen D. ocellatus accumulated up to 10–15% Ca, 0.5% Fe, 15 mg kg−1 d.w. iodine (I), 54.5 mg kg−1 Cr. Battarrea phalloides demonstrated anomalously high concentrations of B, Cu, Fe, Mn Se, Zn, Sr and low Na levels, contrary to Calvatia candida mushrooms accumulating up to 10,850 mg kg−1 Na and only 3 mg kg−1 Sr. The peculiarity of A. lerchiana plants was the high accumulation of B (22.23 mg kg−1 d.w.), Mn (57.48 mg kg−1 d.w.), and antioxidants (total antioxidant activity: 68.6 mg GAE g−1 d.w.; polyphenols: 21.0 mg GAE g−1 d.w.; and proline: 5.45 mg g−1 d.w.). Diploschistes ocellatus and Calvatia candida demonstrated the lowest antioxidant status: 3.6–3.8 mg GAE g−1 d.w. total antioxidant activity, 1.73–2.10 mg GAE g−1 d.w. polyphenols and 2.0–5.3 mg g−1 d.w. proline. Overall, according to the elemental analysis of lichen from Baskunchak Nature Reserve compared to the Southern Crimean seashore, the vicinity of Baskunchak Salty Lake elicited increased environmental levels of Cr, Si, Li, Fe, Co, Ni and Ca.

“…Lichens are symbiotic organisms with an extraordinary capability to colonize areas of extreme climate and heavily contaminated sites, such as metal-rich habitats. Lichens have developed several mechanisms to overcome the toxicity of metals, including the ability to bind metal cations to extracellular sites of symbiotic partners and to subsequently form oxalates [8].…”

This paper provides preliminary data about the influence of gray and yellow lichens on the monuments in the Stobi archeological site. The origin of the minerals which adhere to the rhizine/hyphae was also determined. According to the SEM results, small grains of minerals are found in lichens which originated from parent rocks or weathering. In the lichens on marble the presence of the following minerals was determined: calcite, dolomite, Fe carbonate, Ca silicate, Ca, Fe, Al silicate and Fe, Al silicate. Carbonate minerals come from marble while silicates are the result of weathering.In lichens on sandstone the following minerals were determined: K, Al silicate, Ca carbonate quartz, Fe, Mg silicate, Fe-oxide, zircon, and Na, Ca, Al silicate. Carbonate minerals are the result of weathering while other determined minerals originate from sandstone. Clay minerals are the result of the decomposition of feldspars.

“…It has been reported that lichens are desiccation-tolerant organisms that can survive in harsh environments where higher plants cannot survive [7,8]. Lichens are often found in a variety of extremely dry habitats such as rock surfaces, the Antarctic cold desert and hot deserts [9,10]. In these habitats, the water supply is not delivered by rain but rather in the form of fog, dew or humidity [8,11].…”

Lichens are poikilohydric organisms and an important part of the ecosystem. They show high desiccation tolerance, but the mechanism of dehydration resistance still needs to be studied. The photosynthesis recovery of the photobiont in rehydrated lichen Cladonia stellaris after 11-year desiccation was investigated by simultaneously monitoring both photosystem I and II (PSI and PSII) activities. The responses of the photochemical efficiency and relative electron transport rate (rETR) of PSI and PSII, and the quantum yield of the cyclic electron flow (CEF) were measured using a Dual-PAM-100 system. PSI recovered rapidly, but PSII hardly recovered in C. stellaris during rehydration. The maximal photochemical efficiency of PSII (Fv/Fm) was generally very low and reached about just 0.4 during the rehydration. These results indicated that PSII had restored little and was largely inactivated during rehydration. The quantum yield of PSI recovered quickly to almost 0.9 within 4 h and remained constant at nearly 1 thereafter. The results showed that the activation of the CEF in the early stages of rehydration helped the rapid recovery of PSI. The quantum yield of the CEF made up a considerable fraction of the quantum yield of PSI during rehydration. A regulated excess energy dissipation mechanism and non-photochemical quenching (NPQ) also recovered. However, the small extent of the recovery of the NPQ was not enough to dissipate the excess energy during rehydration, which may be responsible for the weak activity of PSII during rehydration. The results indicated that both CEF and NPQ were essential during the rehydration of the photobiont in C. stellaris. The methods used in the measurements of chlorophyll a fluorescence and P700+ absorbance changes in this study provided a speedy and simple way to detect the physiological characteristics of the photobionts of lichen during rehydration. This work improves our understanding of the mechanism behind lichen’s desiccation tolerance.
