Khodabakhshloo N., Abbasi S., Oleszczuk P. & Turner A. (2024): Biomonitoring of airborne microplastics and microrubbers in Shiraz, Iran, using lichens and moss, Environmental Geochemistry and Health, 46: 244 [14 p.]

Highlights: Microplastics (MPs) and microrubbers (MRs) determined in lichens and mosses around Shiraz. In lichens, MPs mainly thin fibres up to 1 MP g−1; MRs were 0.1 MP g−1. In mosses, abundances were similar but with a greater fraction of larger, non-fibrous particles. Larger MPs and MRs decreased in abundance with distnce and elevation from Shiraz. Around Shiraz, the common moss, Grimmia critina, would be the most suitable biomonitor. Lichens and mosses have been employed as … Read more...

Çobanoğlu G. & Özen E. (2024): Detection of atmospheric microplastics accumulated in Xanthoria parietina: A lichen biomonitoring study on the Asian side of Istanbul, International Journal of Environmental Research, 18: 65 [13 p.]

Airborne microplastics have become invisible global threats to all living organisms today. This study was designed for the first time to monitor atmospheric microplastic pollution in the city of Istanbul (Turkiye) through lichens, known as air pollution biomonitors. Epiphytic foliose lichen Xanthoria parietina was sampled from forested areas in 8 different districts on the Asian side of megacity, and searched for clues of microplastics through chemical characterization and microscopic examination. … Read more...

Hämäläinen A. & Fahrig L. (2024): Time-lag effects of habitat loss, but not fragmentation, on deadwood-dwelling lichens, Landscape Ecology, 39: 111 [16 p.]

Context: Landscape habitat amount is known to increase biodiversity, while the effects of habitat fragmentation are still debated. It has been suggested that negative fragmentation effects may occur with a time lag, which could explain inconsistent results. However, there is so far no empirical support for this idea. Objectives: We evaluated whether habitat amount and fragmentation at the landscape scale affect the species density of deadwood-dwelling lichens, and whether these effects occur … Read more...

Vo Q.V. , Hieu L.T., Hang H.T.C., Diep V.H.N., Hoa N.T., Huynh U.T.D., Trung N.Q. & Mechler A. (2024): Is lecanoric acid a good antioxidant?, Journal of Molecular Liquids, 408: 125336 [6 p.]

Lecanoric acid (LA), an abundant chemical found in lichens, has demonstrated a wide range of biological activities, including anti-cancer cytotoxic, antibiotic, antimycobacterial, antiviral, and anti-hepatocarcinoma properties. The antioxidant capacity of this molecule, while inferred from certain experimental findings, is doubtful based on structural characteristics and therefore remains to be established. DFT calculations are used in this work to conduct a comprehensive evaluation of the mechanism … Read more...

Mendili M., Sellami Z., Somai R. & Khadhri A. (2024): Assessing Tunisia’s urban air quality using combined lichens and Sentinel-5 satellite integration, Environmental Monitoring and Assessment, 196: 545 [19 p.]

In Tunisia, urban air pollution is becoming a bigger problem. This study used a combined strategy of biomonitoring with lichens and satellite mapping with Sentinel-5 satellite data processed in Google Earth Engine (GEE) to assess the air quality over metropolitan Tunis. Lichen diversity was surveyed across the green spaces of the Faculty of Science of Tunisia sites, revealing 15 species with a predominance of pollution-tolerant genera. The Index of Atmospheric Purity (IAP) calculated from the lichen … Read more...

Gačnik J., Živković I., Kotnik J., Božič D., Tassone A., Naccarato A., Pirrone N., Sprovieri F., Steffen A. & Horvat M. (2024): Comparison of active measurements, lichen biomonitoring, and passive sampling for atmospheric mercury monitoring, Environmental Science and Pollution Research, 31: 35800–35810

The number of atmospheric mercury (Hg) monitoring stations is growing globally. However, there are still many regions and locations where Hg monitoring is limited or non-existent. Expansion of the atmospheric Hg monitoring network could be facilitated by the use of cost-effective monitoring methods. As such, biomonitoring and passive monitoring offer a unique alternative to well-established monitoring by active measurements, since they do not require a power supply and require minimal workload to … Read more...

Kachalkin A., Tomashevskaya M., Pankratov T. & Yurkov A. (2024): Endothallic yeasts in the terricolous lichens Cladonia, Mycological Progress, 23: 29 [31 p.]

Lichens are multi-component microbial communities where yeasts are common. This work was designed to address the taxonomic diversity and distribution of cultivated endothallic yeasts in terricolous lichens of the genus Cladonia. Lichens Cladonia stellaris, C. rangiferina, C. cornuta, and C. pleurota from arctic, subarctic, and continental boreal climates in Russia in a range of biotopes were studied. In total, 40 yeast species were isolated. It revealed a broad taxonomic range of endothallic … Read more...

Bogale A.T., Braun M., Bernhardt J., Zühlke D., Schiefelbein U., Bog M., Scheidegger C., Zengerer V., Becher D., Grube M., Riedel K. & Bengtsson M.M. (2024): The microbiome of the lichen Lobaria pulmonaria varies according to climate on a subcontinental scale, Environmental Microbiology Reports, 16: e13289 [14 p.]

The Lobaria pulmonaria holobiont comprises algal, fungal, cyanobacterial and bacterial components. We investigated L. pulmonaria's bacterial microbiome in the adaptation of this ecologically sensitive lichen species to diverse climatic conditions. Our central hypothesis posited that microbiome composition and functionality aligns with subcontinental-scale (a stretch of ~1100 km) climatic parameters related to temperature and precipitation. We also tested the impact of short-term weather dynamics, … Read more...

Johnston P.R. & Park D. (2024): Historical cultures provide insights into the taxonomy of Stictis sensu lato, Fungal Systematics and Evolution, 14: 153–170

Species morphologically typical of the genus Stictis are phylogenetically diverse, spread throughout Stictidaceae. Phylogenetic studies based on DNA sequences have revealed the polyphyletic nature of the morphologically defined genus, the type species Stictis radiata forming a clade phylogenetically distinct from all other sequenced species that had been placed in the genus. Some of the phylogenetic clades containing Stictis sensu lato species can be distinguished on the basis of their asexual … Read more...

Timdal E., Möller E.J. & Bendiksby M. (2024): Rhizocarpon vulgare, a new species in the R. badioatrum species complex, Graphis Scripta, 36(4): 89–105

Herein, we revise the Rhizocarpon badioatrum species complex in the Nordic countries using molecular phylogenetics combined with morphological/anatomical and chemical data. Bayesian and Maximum Likelihood phylogenetic analyses of the nuclear ribosomal internal transcribed spacer (ITS, the fungal DNA barcode) reveals four strongly supported clades within the R. badioatrum species complex. Based on our assessment of the multiple sources of data included, we recognize R. badioatrum var. badioatrum … Read more...
