Petrová K., Bačkorová M., Demčišáková Z., Petrovová E., Goga M., Vilková M., Frenák R., Bačkor M., Mojžiš J. & Kello M. (2022): Usnic acid isolated from Usnea antarctica (Du Rietz) reduced in vitro angiogenesis in VEGF- and bFGF-stimulated HUVECs and ex ovo in quail chorioallantoic membrane (CAM) assay - Life, 12(9): 1444 [18 p.]

Natural products include a diverse set of compounds of drug discovery that are currently being actively used to target tumor angiogenesis. In the present study, we evaluated the anti-angiogenic activities of secondary metabolite usnic acid isolated from Usena antarctica. We investigated the in vitro effects on proliferation, migration, and tube formation of VEGF- and bFGF-stimulated HUVECs. Ex ovo anti-angiogenic activity was evaluated using the CAM assay. Our findings demonstrated that usnic acid … URL EndNote Read more...

[Urbanavichus G.P. & Urbanavichene I.N.] (2022): Ядро заповедника «Кологривский лес» (Россия) – горячая точка биоразнообразия лишайников южной тайги в Восточной Европе [The core of the Kologriv Forest State Nature Reserve (Russia) is a hotspot of lichen biodiversity in the southern taiga of Eastern Europe] - Nature Conservation Research. Заповедная наука, 7(3): 46–63

[in Russian with English abstract: ] In this study, we aim to evaluate the diversity of lichens and allied non-lichenised fungi, co-existing in dark-coniferous and broad-leaved forests of the southern taiga in the East European Plain. The Kologriv Forest State Nature Reserve (589 km2) was established in 2006 to preserve the last fragments of the unique primeval forests of the southern taiga. The territory of the Kologriv cluster of the Kologriv Forest State Nature Reserve (481 km2) is located in … URL EndNote Read more...

Blázquez M. (2022): Preliminary checklist of the lichen-forming and lichenicolous fungi of Castilla-La Mancha (Spain) - Botanica Complutensis, 46: 1–45

A preliminary checklist of lichen-forming and lichenicolous fungi of Castilla-La Mancha is presented. A total of 5064 records have been compiled from 204 publications. The number of taxa ascends to 832, of which 820 are species and 12 infraspecific taxa. Of these 763 are lichenized and 69 correspond to lichenicolous fungi. Keywords.

Kantelinen A., Printzen C., Poczai P. & Myllys L. (2022): Lichen speciation is sparked by a substrate requirement shift and reproduction mode differentiation - Scientific Reports, 12: 11048 [11 p.]

We show that obligate lignicoles in lichenized Micarea are predominately asexual whereas most facultative lignicoles reproduce sexually. Our phylogenetic analyses (ITS, mtSSU, Mcm7) together with ancestral state reconstruction show that the shift in reproduction mode has evolved independently several times within the group and that facultative and obligate lignicoles are sister species. The analyses support the assumption that the ancestor of these species was a facultative lignicole. We hypothezise … URL EndNote Read more...

Kantelinen A., Purhonen J., Halme P. & Myllys L. (2022): Growth form matters – Crustose lichens on dead wood are sensitive to forest management - Forest Ecology and Management, 524: 120529 [12 p.]

Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose lichens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth … URL EndNote Read more...

Monaci F., Ancora S., Paoli L., Loppi S. & Wania F. (2022): Lichen transplants as indicators of gaseous elemental mercury concentrations - Environmental Pollution, 313: 120189 [10 p.]

Lichens play an important role in the biogeochemical cycling of mercury (Hg) and are commonly used as indicators of Hg enrichment in remote and anthropogenically impacted environments. To assess their capacity for Hg uptake and accumulation, we determined the concentration of gaseous elemental mercury (GEM) in air and the concentration of total Hg (THg) in transplanted thalli of two lichen species. Lichen transplants and passive air samplers (PASs) were concurrently deployed, side by side, at 10 … URL EndNote Read more...

Halıcı M.G., Güllü M., Bölükbaşı E. & Kahraman Yiğit M. (2022): Shackletonia backorii - A new species of lichenised fungus from James Ross Island (Antarctic Peninsula) - Turkish Journal of Botany, 46(5): 500–506

The new lichen species Shackletonia backorii Halıcı, Güllü & Kahraman is described from James Ross Island, which is located in the North-East Antarctic Peninsula region. The new species is morphologically most similar to S. insignis (Søchting & Øvstedal) Søchting, Frödén & Arup, which was described from Livingstone Island (North-West Antarctic Peninsula region). These two species have a similar bluish grey to blackish thallus with a microfruticose and coralloid structure and red brown or … URL EndNote Read more...

Marín C., Barták M., Palfner G., Vergara-Barros P., Fernandoy F., Hájek J. & Casanova-Katny A. (2022): Antarctic lichens under long-term passive warming: Species-specific photochemical responses to desiccation and heat shock treatments - Plants, 11(19): 2463 [23 p.]

Climate warming in the Antarctic tundra will affect locally dominant cryptogams. Being adapted to low temperatures and freezing, little is known about the response of the polar lichens’ primary photochemistry to warming and desiccation. Since 2008, we have monitored the ecophysiological responses of lichens to the future warming scenario during a long-term warming experiment through open top chambers (OTCs) on Fildes Peninsula. We studied the primary photochemical response (potential Fv/Fm and … URL EndNote Read more...

Jiang S.-H., Zhang C., Xue X.-D., Aptroot A., Wei J.-C. & Wei X.-L. (2022): Morphological and phylogenetic characterizations reveal five new species of Astrothelium (Trypetheliales, Ascomycota) from China - Journal of Fungi, 8(10): 994 [15 p.]

The lichenized fungal genus Astrothelium is an important element of crustose lichen communities in tropical to subtropical forests. Morphological and molecular phylogenetic approaches to investigate species diversity of Astrothelium (Trypetheliaceae) from Southern China were carried out in this study. Bayesian and maximum-likelihood (ML) analyses were generated based on the combined data set of internal transcribed spacer (ITS), partial regions of the nuclear ribosomal large subunit (LSU), and the … URL EndNote Read more...
