Xu Y., Wang Y., Tong J., Huang R., Yuan H. & Lu J. (2027): From molecular to thermodynamic: An investigation of (+)-usnic acid solubility in pure and binary solvents via multiscale simulation and experiment, Fluid Phase Equilibria, 612: 114832 [21 p.]

The solubility of (+)-usnic acid ((+)-UA) in ten pure solvents and five binary mixed solvents was determined over the temperature range of 283.15–323.15 K. The experimental data for pure solvents were correlated using the modified Apelblat, λh, Wilson and NRTL models, while the General Solubility model (GSM) and the Jouyban-Acree (JA) model were additionally applied to binary solvent systems. The solubility of (+)-UA increased monotonically with temperature and the mass fraction of good solvent, … Read more...

Mitchell R.J., Albon S.D., Bellamy P.E., Cameron C., Cocks L., Ellis C.J., Hodgetts N.G., Johnstone C., Nichols C., Stockan J.A. & Taylor A.F.S. (2026): Pining for diversity: Does greater tree species diversity enhance the resilience of associated biodiversity and ecosystem functioning in Pinus sylvestris forests?, Forest Ecology and Management, 600: 123312 [13 p.]

Pinus sylvestris is widely distributed in the Northern Hemisphere. In the UK it forms the dominant tree in native pine forests and is the only native conifer of economic significance. P. sylvestris is threatened by a range of diseases and climate change. We assess if tree species diversification will provide resilience for P. sylvestris-associated biodiversity and how diversification would alter ecosystem functioning related to decomposition rates and nutrient cycling. Collating existing records, … Read more...

Gupta A., Singh A.P., Singh P.R. & Sinha R.P. (2026): Photoprotective role of the lichen pigment parietin against UVR-induced damage in the cyanobacterium Synechocystis sp. PCC 6803, Dyes and Pigments, 246(1): 113405 [11 p.]

Parietin is an orange anthraquinone secondary metabolite found in the top layer of the upper cortex of some lichens such as Xanthoria elegans. In the present investigation, parietin was characterized using high-performance liquid chromatography (HPLC) alongwith photodiode-array detection and HRMS (retention time: 6.7 min; UV λmax: 265.3, 286.7 and 434 nm; [M+H]+m/z: 284). Cyanobacterial cells are severely damaged by ultraviolet radiation (UVR), which mainly affects their lipids, proteins, DNA, … Read more...

Danko H., Gärtner J., Kasper F., Heinken T., Dengler J. & Karrenberg S. (2026): Vegetation change in dry grasslands in Northeast Germany over two decades: A resurvey, Biological Conservation, 313: 111494 [15 p.]

Semi-natural dry grasslands in Central Europe harbor many rare and specialized species and face threats due to altered management practices and environmental change. However, more studies on vegetation change and management effects in dry grasslands are needed, especially with consideration of non-vascular taxa. Here we used a resurvey approach to analyze vegetation change in dry grasslands on loamy and sandy soils (Festuco-Brometea, Trifolio-Geranietea sanguinei and Koelerio-Corynephoretea canescentis) … Read more...

Palm-Hellenurm K., Jüriado I., Orumaa A., Tullus T. & Metslaid M. (2026): Lichen community development along a post-fire chronosequence in a Scots pine-dominated hemiboreal forests, Forest Ecology and Management, 602: 123394 [10 p.]

Lichens are key components of forest ecosystems, contributing to biodiversity and serving as sensitive indicators of environmental change. Their post-fire dynamics can provide valuable insights into habitat resilience, succession processes, and the ecological impacts of fire. Understanding lichen responses to fire is therefore essential for informing conservation and management in fire-affected forests. This study addresses a key knowledge gap by investigating the recovery dynamics of lichen communities … Read more...

Mugnai M., Di Nuzzo L., Beltramini A., Balzani P., Frasconi Wendt C., Ferretti G., Misuri A., Benesperi R., Viciani D. & Lazzaro L. (2026): Interactions among vascular plants, bryophytes, and lichens in grassland communities along elevational gradients, The Science of Nature, 113: 2 [11 p.]

Grasslands in temperate Europe are key biodiversity hotspots, supporting not only a rich vascular flora but also diverse communities of bryophytes and lichens. However, the processes shaping lichens and bryophytes in these ecosystems, particularly along environmental gradients, remain understudied. We investigated the relative roles of abiotic factors (elevation and rock abundance) and biotic drivers (vascular plant cover and height) in determining both the taxonomic and functional diversity of bryophytes … Read more...

Tretiach M., Ceseri S., Salvadori O., Princivalle F. & Salvadori B. (2026): Superficial rock decalcification by the lichen Tephromela atra var. calcicola: what's true?, International Biodeterioration and Biodegradation, 206: 106215 [8 p.]

The thallus–substrate relationship of Tephromela atra var. calcarea was investigated to determine whether the colonisation of carbonate-rich rock can be related to a “superficial decalcification” of the substrate, as claimed by some authors. Fragments of thalli still adhering to the substrate from the TSB herbarium were embedded in epoxy resin to obtain cross-sections, which were analysed by FPA-FTIR microspectroscopy in reflection mode to acquire chemical imaging data reflecting the spatial … Read more...

(2026): Experimental and In Silico Studies to Unravel the Antioxidant and Antibacterial Properties of Lichen Metabolites from Pseudocyphellaria compar and Pseudocyphellaria nudata, Antioxidants, 15(1): 34 [21 p.]

Lichens are a source of diverse compounds with a wide range of biological activities, making them of significant interest for novel drug development. In this study, metabolites were extracted from Lobariaceae lichens, and their antioxidant and antibacterial properties were experimentally investigated and explained using various computational approaches. Specifically, four lichen metabolites were analyzed using three methods to assess their antioxidant capacity. Antibacterial activity assays were … Read more...

Weber L., Niittynen P. & Kantelinen A. (2026): Lichens in times of climate change – impacts and responses especially in boreal and polar ecosystems, MycoKeys, 128: 29–72

Climate change and biodiversity loss are among the most pressing issues of our time. Lichens have been shown to be sensitive to climate change, but responses are species-specific and contradictory trends have been reported. This review addresses lichen biology in relation to climate change and we overview the responses of lichens (e.g. biotic interactions, species distribution shifts and lichen acclimatisation, adaptation and extinction) to climate (e.g. temperature, precipitation, CO2-levels, snow). … Read more...
