Bryophyte colonization on selected monuments of Champaner Pavagadh UNESCO World Heritage site was investigated. A total of seventeen bryophytes including nine liverworts, six mosses and two hornworts, causing degradation of the monuments, were recorded. The geological substrate was studied by a thin section of substratum and Powder X-Ray Diffraction analysis. Microscopic images of the thin section of geological substrate of the samples showed the presence of quartz, ferruginous materials, calcareous materials, orthoclase and plagioclase feldspar minerals. The XRD analysis spectra revealed the presence of different minerals such as aluminosilicate, calcite, muscovite, hematite, magnetite, orthoclase and plagioclase feldspar. The geological investigation showed that selected monuments are composed of the most calcareous materials. Hence, calcium uptake by Asterella wallichiana (Lehm. & Lindenb.) Grolle and Hyophila involuta (Hook.) A.Jaeger from the substratum was studied using a flame photometer. Maximum calcium uptake (i.e., 52 µg/mg) was obtained for plant samples of Asterella wallichiana compared to Hyophila involuta (i.e., 36 µg/mg). Bryophyte colonization on monuments was initiated by humus formation, followed by the protonema stage, mature gametophyte and rhizoids penetration into crevices as well as porous surfaces, forming cracks and degrading structures. This deterioration mechanism due to bryophyte colonization is explained by pictorial representation. RÉSUMÉ Colonisation de bryophytes sur les monuments de Champaner Pavagadh -site du patrimoine mondial de l'UNESCO et son association avec les substrats géologiques.La colonisation des bryophytes sur des monuments sélectionnés du site de Champaner Pavagadh (classé au patrimoine mondial de l'UNESCO) a été étudiée. Au total, dix-sept bryophytes, dont neuf hépatiques, six mousses, et deux anthocérotes, causant la dégradation des monuments, ont été recensées. Le substrat géologique a été étudié par une coupe fine du substrat et une analyse par diffraction des rayons X sur poudre. Les images microscopiques de la section fine du substrat géologique des échantillons ont montré la présence de quartz, de matériaux ferrugineux, de matériaux calcaires, de minéraux de feldspath orthoclase et plagioclase. Les spectres d'analyse XRD ont révélé la présence de différents minéraux tels que l'aluminosilicate, la calcite, la muscovite, l'hématite, la magnétite, les feldspath orthoclase et plagioclase. L'étude géologique montre clairement que les monuments sélectionnés présentent les matériaux les plus calcaires. Par conséquent, l'absorption de calcium par Asterella wallichiana (Lehm. & Lindenb.) Grolle et Hyophila involuta (Hook.) A.Jaeger à partir du substrat a été étudiée à l'aide d'un photomètre à flamme. L'absorption maximale de calcium (52 µg/mg) a été

“…In the laboratory, samples were ridded of any extraneous material using plastic tweezers and then left overnight at environmental conditions (temperature = 20 ± 2 • C, RH = 65 ± 5%). Although the lichen is an epiphytic species and the moss, reported for heritage sites [43,44], has been not characterized in terms of deteriogenic activity, they were chosen as model organisms considering their ease of collection and handling, and their wide use as bioindicators. Each pool of lichen and moss samples was divided into three batches, loosely wrapped in a plastic net (mesh = 1 cm 2 ) and closed at the extremities with a plastic wire (lichen and moss bags).…”

Accumulation and Phytotoxicity of Two Commercial Biocides in the Lichen Evernia prunastri and the Moss Brachythecium sp.

This study investigated the accumulation and phytotoxicity of two commercial biocides widely used for the removal of biological colonization from monuments, namely Biotin T® (3%) and Preventol RI80® (2%), on lichen and moss model species, specifically, Evernia prunastri and Brachythecium sp. The active compounds, benzalkonium chloride (BAC) for Preventol RI80 and isothiazolinone (OIT) for Biotin T, were accumulated in similar amounts in both species without significant changes for up to 21 days. Both compounds caused a severe impairment of the photosynthetic apparatus of these species, without any recovery over time, although Biotin T showed a faster and stronger action, and the moss was more sensitive than the lichen. By shedding light on the accumulation of BAC and OIT in lichens and mosses and quantifying their effectiveness to photosynthetically devitalize these organisms, the obtained results are a useful comparison for the implementation of green alternative products for the control of biodeteriogens.
