Nunes B.B.S., Braga A., Marques M.E.M., Lopes I. & Cardoso J.C.F. (2025): Are lichens biocompasses? Revisiting an old prediction using new techniques, Plant Biology, 27: 1150–1157

Abiotic factors influence not only vertical distributions of epiphytes, but also their radial positioning, such as around tree trunks. Due to planetary patterns of solar incidence, the equator-facing trunk portions receive direct sunlight, creating restrictive microclimatic conditions. Conversely, pole-facing portions remain shaded, providing optimal conditions for some epiphytes. Since trunk microhabitats are continuous, the distribution of epiphytes involves directional (compass-derived) data, … Read more...

Maliniemi T., Kiilunen P., Bråthen K.A., Kapfer J., Rosendal T.B., Grytnes J.-A., Saccone P. & Virtanen R. (2025): Long-term homogenization of Fennoscandian heathland and tundra vegetation is connected to the expansion of an allelopathic dwarf shrub, Ecography, 2025: e07921 [14 p.]

Boreal and tundra plant communities are expected to change in biodiversity due to increasing global change pressures such as climate warming. One long-term scenario is increasing compositional similarity, i.e. biotic homogenization, which has been relatively little studied in high-latitude plant communities. Here, we study how the composition and diversity of heathland and tundra plant communities have changed in northern Fennoscandia over several decades. In 2013–2023, we resurveyed 275 historic … Read more...

Roos U., Adler S., Lind T. & Sandström P. (2025): Ground lichen cover and response in relation to forest characteristics in Sweden 1993–2023, Global Ecology and Conservation, 64: e03946 [16 p.]

Reindeer husbandry is closely connected to the culture and tradition of the indigenous Sami people, and ground lichens are a key bottleneck resource for winter grazing of the semi-domesticated reindeer. Many factors have been linked to the decrease in ground lichens in the boreal zone. Forestry plays a crucial role in the lichen decline in Swedish forests but is also an important actor with the potential to contribute to a recovery. Forestry is obliged to consider the needs of reindeer husbandry, … Read more...

Nascimbene J., Di Musciano M. & Gheza G. (2025): Resampling epiphytic lichens in coniferous forests of the Southern Alps: Veteran trees promote compositional stability, Perspectives in Plant Ecology, Evolution and Systematics, 69: 125904 [8 p.]

In this study, by means of resampling epiphytic lichens in a timespan of fifteen years in forest stands of the Paneveggio-Pale di San Martino Natural Park (N Italy – Southern Alps), we aim at detecting changes in lichen assemblages by comparing temporal β-diversity patterns between tree individuals of different ages and considering the response pattern of thallus growth forms. Our results indicate that on veteran trees lichen composition seems to be more stable over time. This view is corroborated … Read more...

Bargagli R. & Rota E. (2025): Microplastics in lichen thalli: A photo or a movie of local atmospheric deposition?, Microplastics, 4(4): 85 [12 p.]

Airborne microplastics (MPs) are a global issue, and there is an urgent need to prevent their spread in the environment. Sensitive and reliable methods are also needed to assess their deposition and effectively evaluate risk in terrestrial ecosystems. Current automated monitoring devices are expensive and do not enable large-scale mapping of MP deposition. As with other persistent atmospheric contaminants, developing accurate, cost-effective and easily applicable biomonitoring methods would therefore … Read more...

Heuberger M., Wehrkamp C.M., Pfammatter A., Poretti M., Graf J.P., Herger A., Isaksson J., Schlagenhauf E., Honegger R., Wicker T. & Sotiropoulos A.G. (2025): A reference metagenome sequence of the lichen Cladonia rangiformis, BMC Biology, 23: 319 [22 p.]

Background: Lichens are an ancient symbiosis comprising the thalli of lichen-forming fungi, their photoautotrophic partners, and their microbiome. So far, they were poorly studied at the genome sequence level. Here, we present a reference metagenome for the holobiont of Cladonia rangiformis, aiming to illuminate the genomic complexity and evolutionary interactions within lichen symbioses. Keywords: Metagenome, Bioinformatics, Transposable element, Asterochloris mediterranea, Chromosome-scale … Read more...

Meena S., Chitara D. & Joshi Y. (2025): Mapping potentially toxic elements and ecophysiological stress by using lichen biomonitor Pyxine cocoes (Sw.) Nyl. in Jaipur City, Rajasthan, India, Environmental Monitoring and Assessment, 197: 1285 [16 p.]

Air pollution remains a critical environmental issue with detrimental impact on living organisms and ecosystems’ health. This study evaluates air pollution in Jaipur City using lichen transplantation techniques to examine physiological effects on Pyxine cocoes (Sw.) Nyl. The lichen specimens were collected from Nahargarh Wildlife Sanctuary and transplanted to eleven urban locations for 90-day exposure periods. We measured concentrations of six potentially toxic elements (cadmium, chromium, copper, … Read more...
