Mager E., Brockhage R., Piepenbring M., Segers F., Yorou N.S., Ebersberger I. & Mangelsdorff R.D. (2024): Soil horizons harbor differing fungal communities - Diversity, 16(2): 97 [18 p.]

In the present study, the mycobiomes of two soils with different ecological conditions located in Benin (West Africa) were investigated by environmental sequencing (Illumina MiSeq) of the ITS2-region of ribosomal DNA to gain information about the influence of pedological stratification on fungal diversity. For each soil depth and horizon, fungal diversity and community composition were analyzed as well as the potential impact of site characteristics, like vegetation, on these traits. The retrieved … Read more...

Kammann S., Leinweber P., Glaser K., Schiefelbein U., Dolnik C., Mikhailyuk T., Demchenko E., Heilmann E. & Karsten U. (2024): Successional development of the phototrophic community in biological soil crusts, along with soil formation on Holocene deposits at the Baltic Sea coast - Frontiers in Ecology and Evolution, 11: 1266209 [23 p.]

Harsh environmental conditions form habitats colonized by specialized primary microbial colonizers, e.g., biological soil crusts (biocrusts). These cryptogamic communities are well studied in drylands but much less in temperate coastal dunes, where they play a crucial role in ecological functions. Following two dune chronosequences, this study highlights the successional development of the biocrust’s community composition on the Baltic Sea coast. A vegetation survey, followed by morphological species … Read more...

Woodhouse J., Pérez-Ortega S., Roux C., Bertrand M. & Leavitt S.D. (2024): Diverse communities of endemic and cosmopolitan lineages at local sites in the Lecanora polytropa aggregate (Ascomycota) - Diversity, 16(2): 88 [13 p.]

Recent work has suggested exceptional species-level diversity in the lichen-forming Lecanora polytropa complex (Lecanoraceae, Ascomycota). However, biogeographic patterns and the spatial structuring of this diversity remains poorly known. To investigate diversity across multiple spatial scales, we sampled members of this species complex from two distinct regions—the Pacific Coast Ranges in southern Alaska, USA, and montane habitats in Spain. We also included sequence data from several species within … Read more...

He Z., Naganuma T. & Melville H.I.A.S. (2024): Bacteriomic profiles of rock-dwelling lichens from the Venezuelan Guiana Shield and the South African Highveld Plateau - Microorganisms, 12(2): 290 [18 p.]

Lichens are not only fungal–algal symbiotic associations but also matrices for association with bacteria, and the bacterial diversity linked to lichens has been receiving more attention in studies. This study compares the diversity and possible metabolism of lichen-associated bacteria from saxicolous foliose and fruticose taxa Alectoria, Canoparmelia, Crocodia, Menegazzia, Usnea, and Xanthoparmelia from the Venezuelan Guiana Shield and the South African Highveld Plateau. We used DNA extractions … Read more...

Qu M., Duan W. & Chen L. (2024): The role of cryptogams in soil property regulation and vascular plant regeneration: A review - Applied Sciences, 14(1): 2 [15 p.]

Despite their small size, cryptogams (lichen, liverwort, and moss) are important for ecosystem stability. Due to their strong stress resistance, cryptogams often cover extreme environments uninhabitable for vascular plants, which has an important impact on the material cycle and energy flow of various terrestrial ecosystems. In this article, we review and discuss the effects of cryptogams on soil properties (moisture and fertility) and vascular plant regeneration over the past two decades. Cryptogams … Read more...

Nirhamo A., Hämäläinen A., Hämäläinen K. & Kouki J. (2024): The response of epiphytic lichens on living and dead Pinus sylvestris to prescribed fires of varying severity - Forest Ecology and Management, 551: 121558 [9 p.]

Prescribed burning can be used to restore forest ecosystems degraded by anthropogenic pressures. However, some species such as epiphytic lichens may be vulnerable to fire. We studied the effects of fire on epiphytic lichens on living and dead Pinus sylvestris (Scots pine) by surveying lichens up to two meters on the trunks 21 years after experimental and replicated prescribed burnings in pine-dominated boreal forests in Finland. We investigated three types of stands that had faced different levels … Read more...

Osyczka P., Kościelniak R. & Stanek M. (2024): Old-growth forest versus generalist lichens: Sensitivity to prolonged desiccation stress and photosynthesis reactivation rate upon rehydration - Mycologia, 116(1): 31–43

Most epiphytic lichens demonstrate high specificity to a habitat type, and sensitive hygrophilous species usually find shelter only in close-to-natural forest complexes. Some of them are considered as old-growth forest and/or long ecological continuity indicators. To evaluate general links between the narrow ecological range and physiological traits, two distinct sets of model lichens, i.e., old-growth forest (Cetrelia cetrarioides (Duby) W.L. Culb. & C.F. Culb., Lobaria pulmonaria (L.) Hoffm., Menegazzia … Read more...

Lorenz C., Arena C., Vitale E., 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. (2024): Resilience of Xanthoria parietina under Mars‑like conditions: photosynthesis and oxidative stress response - Planta, 259: 25 [8 p.]

Xanthoria parietina (L.) Th. Fr. is a widespread lichen showing tolerance against air pollutants and UV-radiation. It has been tested under space-like and Mars-like conditions resulting in high recovery performances. Hereby, we aim to assess the mechanisms at the basis of the thalli resilience against multiple space stress factors. Living thalli of X. parietina were exposed to simulated Martian atmospheric conditions (Dark Mars) and UV radiation (Full Mars). Then, we monitored as vitality indicator … 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...

Hollinger J., Scott P.A. & Lendemer J.C. (2024): Two new species of lichenicolous Arthonia (Arthoniaceae) from southeastern North America highlight the need for comparative studies of lichen parasites and their hosts - Bryologist , 127(1): 2–21

Arthonia frostiicola and A. galligena are described as new to science based on collections from mountainous regions of southeastern North America. Arthonia frostiicola infects the saxicolous lichen Dirinaria frostii, producing emarginate black apothecia which erupt from within the host thallus. It is characterized by a dark hypothecium and 1-septate, obovoid ascospores which turn brownish and verruculose in age. It is known from five collections made in the southern Appalachian Mountains and Ozark … Read more...
