Reipert S., Gruber D., Cyran N., Schmidt B., de la Torre Noetzel R., Sancho L.G., Goga M., Bačkor M. & Schmidt K. (2023): Freeze substitution accelerated via agitation: new prospects for ultrastructural studies of lichen symbionts and their extracellular matrix - Plants, 12(23): 4039 [21 p.]

Background: Lichens, as an important part of the terrestrial ecosystem, attract the attention of various research disciplines. To elucidate their ultrastructure, transmission electron microscopy of resin-embedded samples is indispensable. Since most observations of lichen samples are generated via chemical fixation and processing at room temperature, they lack the rapid immobilization of live processes and are prone to preparation artefacts. To improve their preservation, cryoprocessing was tested … Read more...

Kumar T.K., Siva B., Kiranmai B., Alli V.J., Jadav S.S., Reddy A.M., Boustie J., Le Devehat F., Tiwari A.K. & Suresh Babu K. (2023): Salazinic acid and norlobaridone from the lichen Hypotrachyna cirrhata: Antioxidant activity, α-glucosidase inhibitory and molecular docking studies - Molecules, 28(23): 7840 [20 p.]

The present study was intended for the identification of secondary metabolites in acetone extract of the lichen Hypotrachyna cirrhata using UPLC-ESI-QToF-MS/MS and the detection of bioactive compounds. This study led to the identification of 22 metabolites based on their MS/MS spectra, accurate molecular masses, molecular formula from a comparison of the literature database (DNP), and fragmentation patterns. In addition, potent antioxidant and α-glucosidase inhibitory potentials of acetone extract … Read more...

Wang S., Li W., Wufuer R., Duo J., Pei L. & Pan X. (2023): The key role of cyclic electron flow in the recovery of photosynthesis in the photobiont during rehydration of the lichen Cladonia stellaris - Plants, 12(23): 4011 [14 p.]

Lichens are poikilohydric organisms and an important part of the ecosystem. They show high desiccation tolerance, but the mechanism of dehydration resistance still needs to be studied. The photosynthesis recovery of the photobiont in rehydrated lichen Cladonia stellaris after 11-year desiccation was investigated by simultaneously monitoring both photosystem I and II (PSI and PSII) activities. The responses of the photochemical efficiency and relative electron transport rate (rETR) of PSI and … Read more...

Kitaura M.J., Scur M.C. & Lorenz A.P. (2023): A new species of Thyrea (Lichinales: Lichinaceae) from the Brazilian central-west region - Anales de Biología, 45: 43–51

In central-west Brazil, the Serra da Bodoquena region comprises riparian, seasonal deciduous, and semideciduous forests, where ca. 400 lichens species are known. The area is suffering the impacts of agriculture and intentional fires, which threaten the local biodiversity. Studying the lichen-forming fungi from the Serra da Bodoquena through integrative analyses, a new species was discovered, Thyrea pulverulenta (Lichinales, Lichinaceae). In addition, sequences of nuITS and mtSSU regions were generated, … Read more...

Halici M.G., Güllü M., Bölükbaşi E. & Kahraman Yiğit M. (2023): Thamnolecania yunusii (Ramalinaceae) – A new species of lichenised fungus from Horseshoe Island (Antarctic Peninsula) - Polar Record, 59(e37): 1–7

The new terricolous lichen species Thamnolecania yunusii Halıcı, Güllü, Bölükbaşı & Kahraman, which is characterised by its cream to greyish brown granulose-crustose thallus without vegetative propagules, is described from Horseshoe Island in the South-West Antarctic Peninsula region. All Thamnolecania species are known only from the Antarctic. The only species of the genus with a crustose thallus is T. racovitzae, but it differs from T. yunusii by growing on rocks, having an effuse … Read more...

Charria-Girón E., Vasco-Palacios A.M., Moncada B. & Marin-Felix Y. (2023): Colombian fungal diversity: Untapped potential for diverse applications - Microbiology Research, 14(4): 2000–2021

The current list of fungi from Colombia updated in the present review contains a total of 7619 species. The Ascomycota appears as the most diverse group, with 4818 species, followed by the Basidiomycota, with 2555 species. Despite this, we presume that the actual fungal diversity in Colombia could amount to between 105,600 and 300,000 species. Fungi represent an underestimated resource, indispensable for human well-being. Even though the current knowledge on potential applications of Colombian fungi … Read more...

Yangua-Solano E., Carrión-Paladines V. & Benítez Á. (2023): Effects of fire on pyrodiversity of terricolous non-tracheophytes photoautotrophs in a páramo of southern Ecuador - Diversity, 15(12): 1176 [15 p.]

The páramos have a great diversity of flora, including terricolous non-tracheophyte photoautotrophs (bryophytes and lichens). Bryophytes and lichens are very sensitive to environmental changes related to anthropogenic fires, livestock, and agricultural activities. We determined for the first time in Ecuador the effects of prescribed fires on the pyrodiversity of terricolous non-tracheophyte photoautotroph in a páramo of South Ecuador. Three permanent sampling plots (T1, T2, and control) were established, … Read more...

Khalife S. (1986): L' Aire minimale d'un peuplement terricole lichéno-bryophytique (Toninio-Psoretum decipientis Stodiek) - Ecologia Mediterranea, 11(4) : 11-24

[in French with French, Esperanto and English abstract: ] The minimal area of a licheno-bryophytic community (Toninio-Psoretum decipientis Stodiek) is studied hy two methods : - the method of the species-area curve; - the method of the mean similarity-area curve. Only the last method proved to be satisfactory and showed the determination of the qualitative minimal area (250-500cm2) and the quantitative minimal area (500-1000cm2). Read more...
