Abdel-Hameed M.E., Bertrand R.L., Donald L.J. & Sorensen J.L. (2018): Lichen ketosynthase domains are not responsible for inoperative polyketide synthases in Ascomycota hosts, Biochemical and Biophysical Research Communications, 503: 1228–1234

Efforts by lichenologists to characterize lichen polyketide synthases (PKS) through heterologous expression experiments have so far proved unfruitful. A determination of systematic causes of failure is therefore required. Three hypotheses involving the ketosynthase (KS) domain of lichen polyketide synthases (PKS) from Cladonia uncialis are tested: (1) Horizontal versus vertical gene transfer; (2) Typical versus atypical active site residues; (3) Typical versus atypical tertiary protein structure … Read more...

Abdollahi S., Hassanzadeh N., Sohrabi M. & Loppi S. (2025): Biomonitoring of potentially toxic elements in the urban atmosphere of Tehran metropolis using the lichen Anaptychia setifera (Mereschk.) Räsänen, Atmosphere, 16(2): 206 [17 p.]

This study investigated the bioaccumulation of PTEs in the 22 districts of the Tehran metropolis using the lichen Anaptychia setifera collected from Kalpoosh unpolluted area in Semnan province and exposed for 4 months in the study area using the lichen transplant technique. The concentrations of eight potentially toxic elements in the lichen were quantified using ICP-OES analysis. PCA was used to detect common sources of PTEs, and distribution maps were produced using QGIS. A statistically significant … Read more...

Abdullah S.M., Kolo K. & Sajadi S.M. (2020): Greener pathway toward the synthesis of lichen‐based ZnO@TiO2@SiO2 and Fe3O4@SiO2 nanocomposites and investigation of their biological activities, Food Science & Nutrition, 8(8): 4044–4054

A green way is introduced to biosynthesis of ZnO@TiO2@SiO2 and Fe3O4@SiO2 nanocomposites using the bioactive potential of Lecanora muralis (LM) lichen. UV‐Vis spectroscopy and GC–Mass analysis of the lichen show the presence of various bioactive constituents inside the lichen aqueous extract. The XRD, SEM, EDS, and elemental mapping techniques revealed the well fabrication of biosynthesized nanostructures. Also, investigation of antibacterial and antifungal activities of nanostructures demonstrated … Read more...

Abdulmanova S.U. & Ektova S.N. (2015): Variations in the growth rate of Cladonia lichens during long-term postfire successions in the North of West Siberia, Contemporary Problems of Ecology, 8(3): 326–336

This paper presents the results of studying the Cladonia lichen postfire growthrate dynamics in different zonal units of West Siberia. The relative growth rate of lichens in foresttundra and taiga zones was assessed with regard to the pyrogenic factor. The growth rate varied from 1.2 mm/year at the early stage of recovery succession to 11.9 mm/year at the stage of the closed lichen cover. The variations in lichen growth rates at different stages of recovery were reliable in southern and middle … Read more...

Abecasis L., Gamelas C.A., Justino A.R., Dionísio I., Canha N., Kertesz Z. & Almeida S.M. (2022): Spatial distribution of air pollution, hotspots and sources in an urban-industrial area in the Lisbon Metropolitan Area, Portugal—A biomonitoring approach, International Journal of Environmental Research and Public Health, 19: 1364 [20 p.]

This study aimed to understand the influence of industries (including steelworks, lime factories, and industry of metal waste management and treatment) on the air quality of the urbanindustrial area of Seixal (Portugal), where the local population has often expressed concerns regarding the air quality. The adopted strategy was based on biomonitoring of air pollution using transplanted lichens distributed over a grid to cover the study area. Moreover, the study was conducted during the first … Read more...

Abed R.M.M., Al-Sadi A.M., Al-Shehi M., Al-Hinai S. & Robinson M.D. (2013): Diversity of free-living and lichenized fungal communities in biological soil crusts of the Sultanate of Oman and their role in improving soil properties, Soil Biology and Biochemistry, 57: 695-705

Biological soil crusts of arid and semiarid regions are one of the least explored habitats with respect to the diversity of their fungal communities and the Arabian deserts, in particular, remains mycologically poorly investigated. Here, we investigate the diversity of free-living and lichen-forming fungal communities associated with crusts at two locations in Oman, using intensive cultivation and pyrosequencing, and their role in improving soil stability and hydrology. A total of 226 fungal … Read more...

Abella S.R. & Schetter T.A. (2021): Variation in characteristics and conservation values of plant communities on abandoned agricultural lands with and without fires, Applied Vegetation Science, 24(4): e12629

Question: Which plant community characteristics most consistently vary with prior land use? Location: Oak Openings Preserve, Ohio, USA. Methods: In 2020, we measured plant communities on 22 sites encompassing three prior land uses: (a) contemporary Quercus forests continuously forested since before the 1930s; (b) former agricultural lands, under cultivation in the 1930s and abandoned 70–80 years before our study and that were unburned; and (c) former agricultural lands also abandoned 70–80 years … Read more...

Three aromatic constituents have been isolated from the lichen Roccella fuciformis: lepraric acid (1; R = H), the chromone (2), and ethyl orsellinate. Chemical and spectroscopic evidence is presented for the revised structure (1; R = H) of lepraric acid. Read more...
