Yang Q., Wang Y., Lücking R., Lumbsch H. T., Du Z., Chen Y., Bai M., Ren D., Wei J., Li H., Wang Y. & Wei X. (2023): The Jurassic epiphytic macrolichen Daohugouthallus reveals the oldest lichen-plant interaction in a Mesozoic forest ecosystem - iScience, 26: 105770

Lichens are well known as pioneer organisms or stress-tolerant extremophiles, potentially playing a core role in the early formation of terrestrial ecosystems. Epiphytic macrolichens are known to contribute to the water- and nutrient cycles in forest ecosystem. But due to the scarcity of fossil record, the evolutionary history of epiphytic macrolichens is poorly documented. Based on new fossil of Jurassic Daohugouthallus ciliiferus, we demonstrate the hitherto oldest known macrolichen inhabited a … Read more...

Three lichenized fungal species collected from James Ross Island (eastern coast of Antarctic Peninsula): Cladonia acuminata (Ach.) Norrl., Rhizocarpon pusillum Runemark and Rhizoplaca parilis S.D. Leav., Fern.-Mend., Lumbsch, Sohrabi et St. Clair are reported from Antarctica for the first time. Detailed morphological and anatomical properties of these species along with photographes based on Antarctic specimens are provided here. In addition, the nrITS gene regions of the selected specimens are studied … Read more...

Rodríguez-Arribas C., Martínez I., Aragón G., Zamorano-Elgueta C., Cavieres L. & Prieto M. (2023): Specialization patterns in symbiotic associations: A community perspective over spatial scales - Ecology and Evolution, 13: e10296 [16 p.]

Specialization, contextualized in a resource axis of an organism niche, is a core concept in ecology. In biotic interactions, specialization can be determined by the range of interacting partners. Evolutionary and ecological factors, in combination with the surveyed scale (spatial, temporal, biological, and/or taxonomic), influence the conception of specialization. This study aimed to assess the specialization patterns and drivers in the lichen symbiosis, considering the interaction between the principal … Read more...

Økland T., Halvorsen R., Lange T., Nordbakken J.-F. & Clarke N. (2023): Climate change drives substantial decline of understorey species richness and abundance in Norway spruce forests during 32 years of vegetation monitoring - Journal of Vegetation Science, 34: e13191 [22 p.]

Questions Observations in permanent forest vegetation plots in Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised in the “climate-induced understorey change (CIUC)” hypothesis, i.e. that the understorey vegetation of old-growth boreal forests in Norway undergoes significant long-term changes and that these changes are consistent with the ongoing climate change as an important driver. Seven testable predictions were … Read more...

Perini L., Gostinčar C., Likar M., Frisvad J.C., Kostanjšek R., Nicholes M., Williamson C., Anesio A.M., Zalar P. & Gunde‑Cimerman N. (2023): Interactions of fungi and algae from the Greenland Ice Sheet - Microbial Ecology, 86: 282–296

Heavily pigmented glacier ice algae Ancylonema nordenskiöldii and Ancylonema alaskanum (Zygnematophyceae, Streptophyta) reduce the bare ice albedo of the Greenland Ice Sheet, amplifying melt from the largest cryospheric contributor to eustatic sea-level rise. Little information is available about glacier ice algae interactions with other microbial communities within the surface ice environment, including fungi, which may be important for sustaining algal bloom development. To address this … Read more...

Zhou R., Zhang L., Zeng B., Zhou Y., Jin W. & Zhang G. (2023): A novel self‑purifed auxiliary protein enhances the lichenase activity towards lichenan for biomass degradation - Applied Microbiology and Biotechnology , 107: 4553–4566

Due to the complex composition of lichenan, lichenase alone cannot always hydrolyze it efciently. Carbohydrate-binding modules (CBMs) and lytic polysaccharide monooxygenases (LPMOs) have been confrmed to increase the hydrolysis efciency of lichenases. However, their practical application was hampered by the complex and costly preparation procedure, as well as the poor stability of LPMOs. Herein, we discovered a novel and stable auxiliary protein named SCE to boost the hydrolysis efciency. … Read more...

Özkök E.A. & Çobanoğlu G. (2023): Spatial evaluation of air quality by biomonitoring of toxic element accumulation in lichens in urban green areas and nature parks on the Anatolian side of Istanbul - Environmental Monitoring and Assessment , 195: 908 [14 p.]

The city of Istanbul is constantly exposed to air pollution due to its high population, heavy traffic — sea and air transport — and urban industry. This study basically aims to determine the recent level of airborne heavy metals, using lichen biomonitoring method. The cosmopolitan foliose lichen Xanthoria parietina growing abundantly on trees was sampled from 16 urban green spaces in 8 districts on the Anatolian side of Istanbul. Multi-element analysis by ICP-MS was applied to … Read more...

Gaia G., Ribeiro V.R., Ghilardi R.P., Sousa F.N., Llopart M.P. & Ricardi-Branco F. (2023): Chemical and elementary characterization of Spongiophyton nanum: Understanding the phylogeny, paleoenvironment, and fossilization processes of an enigmatic flora - Review of Palaeobotany and Palynology , 316: 104943 [11 p.]

The record of thalloid macrofossils in the North-Northwest region of the Paran´ a Basin is less studied compared to that of invertebrate paleofauna in the same area. Consequently, the lack of important information regarding the niches occupied by thalloid embryophytes during early land colonization in this coastal paleoenvironment is evident. This study presents the first chemical and elemental data on Spongiophyton for this region of the basin, offering insights into its paleoenvironment … Read more...

Demková L., Bobuľská L, Árvay J., Homolová Z., Michalko M. & Balintová M. (2023): Potentially toxic elements in soil and air along an altitudinal gradient in Tatra National Park - Journal of Geochemical Exploration, 252: 107268 [9 p.]

With a growing number of tourists, national parks are facing high pressure in terms of production and spreading the potentially toxic elements (PTEs). Car parks, roads or civil amenities have become a source of PTEs, which are spreading not only in their immediate vicinity, but can contaminate much wider surroundings. Total content of Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb and Zn was determined in soil samples and, also in mosses and lichen samples, which were used as bioindication method for air pollution … Read more...

Thakur M., Kapoor B., Kapoor D. & Sharma N.R. (2023): Lichens: A promising source of anti-cancerous activity and their molecular mechanisms - South African Journal of Botany, 159: 155–163

The potential of lichens for medicinal use is to have a variety of bioactive anticancer compounds. Several factors drive the issue of lichens as a usual substance of carcinoma chemicals for lichens. In a variety of climates which could be represented by extreme climatic variables, lichens can endure heat intensities, Ultraviolet rays, limited nutrient uptake, humidity, etc. Their results are obtained is due to the possible defence system they have towards severe change, simultaneously generating … Read more...
