Frati L. & Brunialti G. (2023): Recent trends and future challenges for lichen biomonitoring in forests - Forests, 14(3): 647 [18 p.]

Currently, forest ecosystems are often located in remote areas, far from direct sources of air pollution. Nonetheless, they may be affected by different types of atmospheric deposition, which can compromise their health and inner balance. Epiphytic lichens respond to air pollution and climate change, and they have been widely adopted as ecological indicators, mainly in urban and industrial areas, while forest ecosystems are still underrepresented. However, in recent years, their use has become increasingly … Read more...

Ruiz L., Carrión-Paladines V., Vega M., López F. & Benítez Á. (2023): Biological crust diversity related to elevation and soil properties at local scale in a montane scrub of Ecuador - Journal of Fungi, 9(3): 386 [13 p.]

The montane shrublands of southern Ecuador represent one of the least studied ecosystems, which in the last decade have been seriously threatened by increasing wildfires, deforestation, overgrazing, and conversion to forest plantations. Our main objective was to determine, at the local scale, the diversity of species composing the biological soil crust (BSC) at three elevations (2100, 2300, and 2500 m.a.s.l.) and their possible relationships with soil physical and chemical properties in montane shrublands. … Read more...

Kukwa M., Kosecka M., Jabłońska A., Flakus A., Rodriguez-Flakus P. & Guzow-Krzemińska B. (2023): Pseudolepraria, a new leprose genus revealed in Ramalinaceae (Ascomycota, Lecanoromycetes, Lecanorales) to accommodate Lepraria stephaniana. - MycoKeys, 96: 97–112

The new genus Pseudolepraria Kukwa, Jabłońska, Kosecka & Guzow-Krzemińska is introduced to accommodate Lepraria stephaniana Elix, Flakus & Kukwa. Phylogenetic analyses of nucITS, nucLSU, mtSSU and RPB2 markers recovered the new genus in the family Ramalinaceae with strong support. The genus is characterised by its thick, unstratified thallus composed entirely of soredia-like granules, the presence of 4-O-methylleprolomin, salazinic acid, zeorin and unknown terpenoid, and its phylogenetic position. … Read more...

Pichler G., Muggia L., Carniel F., Grube M. & Kranner I. (2023): How to build a lichen: from metabolite release to symbiotic interplay - New Phytologist, 238(4): 1362–1378

Exposing their vegetative bodies to the light, lichens are outstanding amongst other fungal symbioses. Not requiring a pre-established host, 'lichenized fungi' build an entirely new structure together with microbial photosynthetic partners that neither can form alone. The signals involved in the transition of a fungus and a compatible photosynthetic partner from a free-living to a symbiotic state culminating in thallus formation, termed 'lichenization', and in the maintenance of the symbiosis, are … Read more...

Kelsey K.C., Pedersen S.H., Leffler A.J., Sexton J.O. & Welker J.M. (2023): Snow and vegetation seasonality influence seasonal trends of leaf nitrogen and biomass in Arctic tundra - Ecosphere, 14: e4515 [15 p.]

Climate change, including both increasing temperatures and changing snow regimes, is progressing rapidly in the Arctic, leading to changes in plant phenology and in the seasonal patterns of plant properties, such as tissue nitrogen (N) content and community aboveground biomass. However, significant knowledge gaps remain over how these seasonal patterns vary among Arctic plant functional groups (i.e., shrubs, grasses, and forbs) and across large geographical areas. We used three years of in situ field … Read more...

Yuan X., Li Y., Luo T., Bi W., Yu J. & Wang Y. (2023): Genomic Analysis of the Xanthoria elegans and Polyketide Synthase Gene Mining Based on the Whole Genome - Mycobiology, 51(1):36-48

Xanthoria elegans is a lichen symbiosis, that inhabits extreme environments and can absorb UV-B. We reported the de novo sequencing and assembly of X. elegans genome. The whole genome was approximately 44.63 Mb, with a GC content of 40.69%. Genome assembly generated 207 scaffolds with an N50 length of 563,100 bp, N90 length of 122,672 bp. The genome comprised 9,581 genes, some encoded enzymes involved in the secondary metabolism such as terpene, polyketides. To further understand the UV-B absorbing … Read more...

Lorenz C., Bianchi E., Poggiali G., Alemanno G., Benesperi R., Brucato J.R., Garland S., Helbert J., Loppi S., Lorek A., Maturilli A., Papini A., de Vera J.-P. & Baqué M. (2023): Survivability of the lichen Xanthoria parietina in simulated Martian environmental conditions - Scientific Reports, 13: 4893 [15 p.]

Xanthoria parietina (L.) Th. Fr. is a widely spread foliose lichen showing high tolerance against UV-radiation thanks to parietin, a secondary lichen substance. We exposed samples of X. parietina under simulated Martian conditions for 30 days to explore its survivability. The lichen’s vitality was monitored via chlorophyll a fluorescence that gives an indication for active light reaction of photosynthesis, performing in situ and after-treatment analyses. Raman spectroscopy and TEM were used to … Read more...

Perlmutter G.B., Miranda-Gonzáles R. & Bungartz F. (2023): Placement of Arthonia rubrocincta in Coniocarpon (lichenized Ascomycota: Arthoniaceae), with an extended range for the species in southeastern North America and the Caribbean - Phytotaxa, 589(3): 278–282

Arthonia rubrocincta morphologically and anatomically fits the generic concept of Coniocarpon and is here transferred to the latter genus as Coniocarpon rubrocinctum. Specimens from southeastern United States and Bahamas were studied and the range of the species is found to extend north into North Carolina, USA and southeast to the Bahamas. Thatch palm (Coccothrinax argentata) is reported as a new phorophyte. An emended description based on examined material is presented for the species. Keywords: … Read more...
