Matvienko A.I., Evgrafova S.Y., Kovaleva N.M., Sideleva E.V., Sitnikova M.V., Menyailo O.V. & Masyagina O.V. (2024): Greenhouse gas fluxes from the epiphytic lichens: incubation experiments - Forests, 15(1): 107 [10 p.]

Because they are widespread and evolutionarily old, epiphytic lichens (ELs) play an important role in global forest ecosystems. ELs are abundant in Siberian forest ecosystems, which are highly vulnerable to climate change; thus, ELs can be important contributors to the carbon (C) cycle. This study aims to address the unknown role of tree-inhabiting ELs in the C cycle of forest ecosystems in Central Siberia, where the EL biomass ranges from 492 to 3200 kg per ha. The main finding of this study is … Read more...

Shamblin Z. & Puppo P. (2024): Developing a 3D digitization protocol at the Marshall University Herbarium using free, open-source 3D reconstruction software - Castanea, 88(2): 191–204

Herbarium specimen digitization and transcription initiatives have led to revitalized use of plant collections making them more accessible than ever. Most digitization is done by producing 2D images of herbarium sheets; however, herbaria also include 3D collections such as fungi, mosses, and dry fruits, among others. Here we present a 3D digitization protocol developed at the Marshall University Herbarium (MUHW) using free photogrammetry software. We tested four freely available software applications, … Read more...

Silva T.E.F., da Silva M.S.R.C., dos Santos M.A.L., Cáceres M.E.S., Aptroot A. & Vitória N.S. (2024): Two new Arthoniales species (lichenized Ascomycota) from Brazil - Revista de Gestão Social e Ambiental, 18(4): e04543 [13 p.]

Objective: The present work aimed to describe, comment, and illustrate two new lichenized species of Ascomycota. Method: Morphological analyses of the samples were performed at the Laboratory in the State University of Bahia (UNEB), Campus VIII. The lichen thalli were observed using a stereomicroscope (Zeiss); chemical treatments were performed to observe the microscopic structures of the lichens after exposure to 10% KOH (potassium hydroxide), lactophenol (cotton blue), Melzer’s reagent, chlorine, … Read more...

Thiers B.M. (2024): Strengthening partnerships to safeguard the future of herbaria - Diversity, 16(1): 36 [10 p.]

Herbaria remain the primary means of documenting plant life on earth, and the number of herbaria worldwide and the number of specimens they hold continues to grow. Digitization of herbarium specimens, though far from complete, has increased the discoverability of herbarium holdings and has increased the range of studies from which data from herbarium specimens can be used. The rather large number of herbaria about which no current information is available is a source of concern, as is herbarium consolidation … Read more...

Ertz D. & Lebreton E. (2024): A new corticolous species of Mazosia A.Massal. (Roccellaceae, Arthoniales) from Guadeloupe, remarkable by its byssoid thallusv - Cryptogamie, Mycologie, 45(1): 1–10

An unknown species of Roccellaceae Chevall. was collected in 2022 and 2023 on the bark of trunks in a rainforest in Basse-Terre island (Guadeloupe, Lesser Antilles). Phylogenetic analyses using mtSSU, nuLSU and RPB2 sequences reveal the placement of the species in the genus Mazosia A.Massal. (Roccellaceae). The lichen is unusual for the genus by being the first species of Mazosia developing a byssoid thallus. It is described as Mazosia byssoidea Lebreton & Ertz, sp. nov. Besides it byssoid thallus, the … Read more...

Zhang Y., Yin Y., Wang L., Printzen C., Wang L. & Wang X. (2024): Two new species of Rhizoplaca (Lecanoraceae) from Southwest China - MycoKeys, 101: 233–248

In this study, two new species, Rhizoplaca adpressa Y. Y. Zhang & Li S. Wang and R. auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplaca chrysoleuca-complex. Rhizoplaca adpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin … Read more...

Studzińska-Sroka E., Bulicz M., Henkel M., Rosiak N., Paczkowska-Walendowska M., Szwajgier D., Baranowska-Wójcik E., Korybalska K. & Cielecka-Piontek J. (2024): Pleiotropic potential of Evernia prunastri extracts and their main compounds evernic acid and atranorin: in vitro and in silico studies - Molecules, 29: 233 [31 p.]

Evernia prunastri is a lichen widely distributed in the Northern Hemisphere. Its biological properties still need to be discovered. Therefore, our paper focuses on studies of E. prunastri extracts, including its main metabolites evernic acid (EA) or atranorin (ATR). Phytochemical profiles using chromatographic analysis were confirmed. The antioxidant activity was evaluated using in vitro chemical tests and in vitro enzymatic cells-free tests, namely superoxide dismutase (SOD), glutathione peroxidase … Read more...

Kholod S., Konoreva L. & Chesnokov S. (2024): Influence of orographic factors on the distribution of lichens in the Franz Josef Land archipelago - Plants, 13(2): 193 [23 p.]

During a geobotanical study of the Franz Josef Land archipelago, 111 lichen species were recorded on 130 sample plots. The significance of orographic factors in the distribution of lichens was assessed using principal component analysis (PCA) and multiple regression analysis. It was found that the absolute altitude and distance from the glacier are of the greatest importance for crustose lichens, while for fruticose lichens, the most critical factors were the slope exposure and steepness. Along the … Read more...

Paz-Bermúdez G., Fernández-Salegui A.B., Hespanhol H., López de Silanes M.E., Vieira C. & Calviño-Cancela M. (2024): Effects of the abandonment of traditional cultural practices on epiphytic bryolichenic communities in chestnut orchards in north-west Spain - Forests, 15(1): 160 [21 p.]

This study delves into the impact of contrasting management practices on epiphytic bryolichenic communities, shedding light on their divergent responses to management regimes on Castanea sativa Mill. orchards. Lichens and bryophytes were sampled in managed and abandoned plots, in 95 trees, in north and south sides and at two heights in Galicia (NW Spain). The studied groups exhibited opposing reactions to these management practices; bryophytes suffered adverse effects in managed stands, experiencing … Read more...

Ndhlovu N.T., Minibayeva F. & Beckett R.P. (2024): A role for secondary metabolites in desiccation tolerance in lichens - Microbiology Research, 15(1): 225–235

In lichens, secondary metabolites have been shown to protect against biotic stresses such as pathogen attacks and grazing, and abiotic stresses such as ultraviolet (UV) and high photosynthetically active radiation (PAR). Lichen secondary metabolites are known to have strong antioxidant activity, and while theoretically they may have roles in tolerance to other abiotic stresses, these roles remain largely unclear. Here, we used the acetone rinsing method to harmlessly remove most of the secondary … Read more...
