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...

Мелехин А.В. [Melekhin A.V.] (2026): Новые для Мурманской области виды на северной границе распространения [Lichens new for the Murmansk Region at the northern limit of distribution] , Труды Карельского научного центра РАН, Серия "Биогеография", Петрозаводск [Transactions of the Karelian Research Centre of Russian Academy of Science, ser. Biogeography, Petrozavodsk], 2026/3: 142–145

[in Russian with English abstract: ] Three lichen species previously unknown for the Murmansk Region are reported at the northern limit of their distribution and away from areas with their concentrated populations: Lecania naegelii, Porina lectissima, and Psora testacea. Porina lectissima was found in the northeast of the region, and the other two in the Khibiny Mountains. All the species are common in southerner regions of the world. Keywords: lichens; new records; calcicolous species; Murmansk … 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...

Cuellar M.A., Mejía J., Quintero-Pertuz H., Castro-Álvarez A., Mellado M., Vera-Quezada W., Montenegro G., Espinosa-Bustos C., Bridi R. & Salas C.O. (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...

İğci B.K. & İğci N. (2026): Chemically diverse: Chemotaxonomic discrimination and comparative fingerprinting of intact lichens from different families and genera using Fourier transform infrared (FTIR) spectroscopy and chemometrics, Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 349: 127260 [19 p.]

Lichen extracts or their purified compounds are invaluable biomaterials with both commercial and traditional applications. In lichen systematics, chemotaxonomy is commonly employed, primarily relying on metabolites. Fourier transform infrared (FTIR) spectroscopy is a powerful analytical technique for identifying chemical compounds in various materials. This study aimed to evaluate its ability to differentiate between lichen taxa and detect their chemical constituents. FTIR spectra were obtained in … 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...
