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...

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...

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...

Raniga D., Amarasingam N., Sandino J., Doshi A., Barthelemy J., Randall K., Robinson S.A., Gonzalez F. & Bollard B. (2024): Monitoring of Antarctica’s fragile vegetation using drone-based remote sensing, multispectral imagery and AI - Sensors, 24(4): 1063 [30 p.]

Vegetation in East Antarctica, such as moss and lichen, vulnerable to the effects of climate change and ozone depletion, requires robust non-invasive methods to monitor its health condition. Despite the increasing use of unmanned aerial vehicles (UAVs) to acquire high-resolution data for vegetation analysis in Antarctic regions through artificial intelligence (AI) techniques, the use of multispectral imagery and deep learning (DL) is quite limited. This study addresses this gap with two pivotal contributions: … Read more...

Svanberg I. & Ståhlberg S. (2024): Peasant food provision strategies and scientific proposals for famine foods in eighteenth-century Sweden - Gastronomy, 2(1): 18–37

The peasant diet during the Little Ice Age in Sweden was mainly grain-based (bread, gruel, and porridge), and the country was heavily dependent on grain imports to meet the population’s needs for food. During the eighteenth century in particular, when famines were frequent following failed harvests, Swedish peasants utilized a range of locally available resources to survive. Bark bread made of cambium (phloem) from Pinus sylvestris was, for example, commonly used as famine food. Scientists of the … Read more...

Pradhan S., Dash S., Sahoo B., Parida S. & Rath B. (2024): Screening and characterization of bioactive compounds from two epiphytic microlichen and evaluation of their in vitro antioxidant activity - Future Journal of Pharmaceutical Sciences, 10: 10 [19 p.]

Background: Lichens in symbiosis produce a wide range of primary and secondary fne compounds in extreme environmental conditions that have a broad range of biological properties as well as antioxidant potential and can be used in future pharmaceuticals as a natural source of antioxidant molecules. Results: The two microlichen species collected are identifed based on morphological and molecular techniques; further studies are carried out by analyzing phytochemicals (FTIR, GC MS), and antioxidant … Read more...

Makhnykina A.V., Vaganov E.A., Panov A.V., Koshurnikova N.N. & Prokushkin A.S. (2024): The pulses of soil CO2 emission in response to rainfall events in Central Siberia: revisiting the overall frost-free season CO2 flux - Forests, 15(2): 355 [16 p.]

Boreal forests nowadays act as a sink for atmospheric carbon dioxide; however, their sequestration capacity is highly sensitive to weather conditions and, specifically to ongoing climate warming. Extreme weather events such as heavy rainfalls or, conversely, heat waves during the growing season might perturb the ecosystem carbon balance and convert them to an additional CO2 source. Thus, there is an urgent need to revise ecosystem carbon fluxes in vast Siberian taiga ecosystems as influenced by extreme … Read more...

Silva I., Salvador C., Arantes S., Miller A.Z., Candeias A. & Caldeira A.T. (2024): The decorated garden Grotto of Condes de Basto Palace in Évora, Portugal: microbial community characterization and biocide tests for conservation - Micro, 14: 117–131

The Eugénio de Almeida Foundation’s Casa de Fresco is a historical monument of valuable historic–artistic significance, which currently reveals an assortment of biofilms due to the proliferation of microorganisms in the stone and rocaille elements. The biodeterioration in this area was studied as part of the Conservation and Restoration Project. We effectively characterized the local microbial community using modern high-throughput DNA analysis. Our results suggested the existence of a variety … Read more...

Lichens were investigated in two upland areas in Brazil from which lichens were described in historical times. The main aim was to recollect topotypes, but 37 species turned out to be new records for Brazil. Also, 25 new lichen species are described, all from South Brazil: Acarospora aggregata, Allographa triangularis, Arthotheliopsis corticola, Astrothelium flavocrystallinum, Astrothelium flavoinspersum, Astrothelium macrostromaticum, Caloplaca fuscospora, Caloplaca marginireflectans, Cladonia sticticocrustosa, … Read more...
