Leavitt S.D., DeBolt A., McQuhae E. & Allen J.L. (2023): Genomic resources for the first federally endangered lichen: the Florida Perforate Cladonia (Cladonia perforata) - Journal of Fungi, 9(7): 698 [15 p.]

Thirty years after its designation as a federally endangered species, the Florida Perforate Cladonia (FPC) remains imperiled in isolated populations in the Florida scrub in the southeastern USA. For threatened and endangered species, such as FPC, reference genomes provide critical insight into genomic diversity, local adaptations, landscape-level genetics, and phylogenomics. Using high-throughput sequencing, we assemble the first draft nuclear and mitochondrial genomes for the FPC mycobiont—Cladonia … Read more...

Allain A., Alexis M.A., Bridoux M.C., Humbert G., Agnan Y. & Rouelle M. (2023): Fingerprinting the elemental composition and chemodiversity of vegetation leachates: consequences for dissolved organic matter dynamics in Arctic environments - Biogeochemistry, 164: 73–98

Dissolved organic matter is a key compartment for biogeochemical cycles in the Arctic and Subarctic terrestrial environments. With changing vegetation ecosystems, the chemical composition of organic matter is expected to shift and thus, the most labile part of it, namely the extractable fraction. To this date, few studies have focused on the fingerprinting of DOM fraction from different primary sources, and even less on its potential repercussions on the environment. In this study, we jointly characterized … Read more...

Gorbunova A.M., L.S. Gorbunov L.S. & Veselkin D.V. (2023): Changing the reserves of green and lichen forage stocks in the southern tundra communities of Yamal from the 1930s to 2017–2019 - Russian Journal of Ecology, 54(2): 77–87

[Original Russian Text published in Ekologiya, 2023, No. 2, pp. 83–93.] We compared the reindeer forage stocks at two landfills in the southern part of the Yamal Peninsula for the period from the early 1930s to 2017–2019. Data from [30] was used to characterize the feedstock in the 1930s. Feedstocks in the 1930s and 2017–2019 in plant communities in the basins of the the Erkatayakha and Baidaratayakha rivers were compared in the following vegetation divisions: lichen and shrub tundras; … Read more...

Erschbamer B., Niederfriniger Schlag R., Carnicero P. & Kaufmann R. (2023): Long‑term monitoring confirms limitations of recruitment and facilitation and reveals unexpected changes of the successional pathways in a glacier foreland of the Central Austrian Alps - Plant Ecology , 224: 373–386

On a glacier foreland of the Central Austrian Alps, a permanent plot study was performed to investigate the successional pathway on two moraines. We expected that the pioneer stage deglaciated for 25 years will converge to an early successional stage after another 25 years and the early stage deglaciated for 40 years will show trends toward a late successional stage. Different dynamics of species occurrence such as colonization/persistence and cover increase/decrease, were anticipated. Twenty plots … Read more...

Villagra J., Sancho L.G. & Alors D. (2023): Macrolichen communities depend on phorophyte in Conguillío National Park, Chile - Plants, 12(13): 2452 [13 p.]

The community composition of epiphytic macrolichens from two tree species (Araucaria araucana and Nothofagus antarctica) was conducted in temperate forests in the Conguillío National Park, Chile. The composition of lichen biota is influenced by phorophyte species, bark pH, and microclimatic conditions. A total of 31 species of macrolichens were found on A. araucana and N. antarctica. Most of the species showed phorophyte preference, with nine being exclusive to A. araucana and 10 to N. antarctica. … Read more...

Chirva O.V., Nikerova K.M., Ignatenko R.V., Androsova V.I. & Tarasova V.N. (2023): Superoxide dismutase and catalase activity as an indicator of the ontogenetic state of the threatened lichen Lobaria pulmonaria (L.) Hoffm. in the middle boreal subzone - Russian Journal of Plant Physiology, 70: 76 [7 p.]

It is well-known that the switch of an organism ontogenetic state is accompanied with the change in metabolic status, especially, the activity of antioxidant system enzymes. However, there is still lack of knowledge about the internal changes which occur during the shift between ontogenetic stages in lichens. In this study, superoxide dismutase (SOD) and catalase (CAT) activities were measured for Lobaria pulmonaria thalli from middle boreal subzone on the Karelian Republic territory. We have … Read more...

Poulsen-Silva E., Gordillo-Fuenzalida F., Atala C., Moreno A.A. & Otero M.C. (2023): Bioactive lichen secondary metabolites and their presence in species from Chile - Metabolites, 13(7): 805 [35 p.]

Lichens are symbiotic organisms composed of at least one fungal and one algal species. They are found in different environments around the world, even in the poles and deserts. Some species can withstand extreme abiotic conditions, including radiation and the vacuum of space. Their chemistry is mainly due to the fungal metabolism and the production of several secondary metabolites with biological activity, which have been isolated due to an increasing interest from the pharmaceutical community. However, … Read more...

van den Boom P.P.G., Lücking R. & Sipman H.J.M. (2023): Notes on Graphidaceae in Macaronesia, with descriptions of four new species - Diversity, 15(7): 817 [21 p.]

A survey of the lichen family Graphidaceae in Macaronesia (Madeira, the Canary Islands, and the Azores) is presented, with detailed treatments for the genera Allographa, Fissurina, and Graphis. All other species are listed and new records provided. A key to all Graphicacy known from Macaronesia, except the thelotremoid species, is presented. The following species are newly described: Fissurina azorica, Fissurina elaiocarpoides, Fissurina nigrolabiata, and Topeliopsis juniperina. Many species are … Read more...

Golubkina N., Tolpysheva T., Lapchenko V., Lapchenko H., Pirogov N., Zaitsev V., Sękara A., Tallarita A., Stoleru V., Murariu O.C. & Caruso G. (2023): Comparative evaluation of antioxidant status and mineral composition of Diploschistes ocellatus, Calvatia candida (rostk.) [sic!] Hollós, Battarrea phalloides and Artemisia lerchiana in conditions of high soil salinity - Plants, 12(13): 2530 [16 p.]

Natural reserves play a fundamental role in maintaining flora and fauna biodiversity, but the biochemical characteristics of such ecosystems have been studied in an extremely fragmentary way. For the first time, mineral composition and antioxidant status of three systematic groups of organisms, lichens (Diplischistes ocellatus), mushrooms (Calvatia candida and Battarrea phalloides) and wormwood (Artemisia lerchiana) have been described at the territory of Bogdinsko-Baskunchak Nature Reserve (Astrakhan … Read more...

Chircov C., Bîrcă A.C., Dănciulescu L.A., Neacșu I.A., Oprea O.-C., Trușcă R.-D. & Andronescu E. (2023): Usnic acid-loaded magnetite nanoparticles—A comparative study between synthesis methods - Molecules, 28(13): 5198 [14 p.]

Since cancer is a continuously increasing concern for the general population, more efficient treatment alternatives ought to be developed. In this regard, a promising direction is represented by the use of magnetite nanoparticles (MNPs) to act both as a nanocarrier for the targeted release of antitumoral drugs and as hyperthermia agents. Thus, the present study focused on improving the control upon the outcome properties of MNPs by using two synthesis methods, namely the co-precipitation and microwave-assisted … Read more...
