Buril M.L.L., de Oliveira Silva A.K., Martins M.C.B., Silva H.P.B., Aptroot A., da Silva B.F. & Pereira E.C. (2024): Species of Peltula (lichenized Ascomycota) are shown to tolerate rock substrate rich in natural γ-radiation in NE Brazil, Total Environment Advances, 10: 200099 [9 p.]

Pedra Municipality in Pernambuco State (Northeastern Brazil) is known for encompassing areas with high natural radiation from 238U sources, contaminating soil, atmosphere, water, vegetation, and animals, including rural activities. A lichen survey was performed in the area, and species belonging to 19 genera were identified. The diversity is considered very low when compared to nearby municipalities and other similar regions, which might indicate the effect of radiation on the environment. The lichen … Read more...

Allain A., Alexis M.A., Bridoux M.C., Shirokova L.S., Payandi-Rolland D., Pokrovsky O.S. & Rouelle M. (2024): The specific molecular signature of dissolved organic matter extracted from different arctic plant species persists after biodegradation, Soil Biology and Biochemistry, 193: 109393 [12 p.]

Dissolved organic matter (DOM) is a small but very reactive pool of organic matter (OM) in the environment. Its role is related to its composition, which depends on its source. In soils, vegetation is the main source of DOM, and biodegradation is the main regulating mechanism. This study aims to characterise DOM produced by contrasted arctic vegetation species and their biodegradation products. The water-extractable organic matter (WEOM) was produced from C. stellaris (lichen), E. vaginatum (sedge), … Read more...

He L., Chen W., Fraser R.H., Schmelzer I., Arsenault A., Leblanc S.G., Lovitt J., White H.P., Plante S. & Brodeur A. (2024): Satellite-detected decreases in caribou lichen cover, Cladonia (Cladina) spp., over Eastern Canada during the last three decades, Forest Ecology and Management, 556: 121753 [11 p.]

Caribou lichens, Cladonia (Cladina) spp., are a slow-growing, vital winter forage for caribou that are likely to be influenced by global warming. However, the large-scale response of caribou lichens to changing global climate remains unclear. Here, we derived caribou lichen cover maps for two time periods ∼30 years apart (i.e., the late 1980 s, and 2020 s) using Landsat satellite imagery for a region (0.59 million km2) in Eastern Canada that includes all or portions of several boreal caribou population … Read more...

Liang X., Chen W., Jiang B. & Xiao C.-J. (2024): Dibenzofurans from nature: Biosynthesis, structural diversity, sources, and bioactivities, Bioorganic Chemistry, 144: 107107 [17 p.]

Dibenzofurans are a small class of natural products with versatile biological activities that used to be thought to come mainly from lichens and ascomycetes. In fact, they are also distributed widely in higher plants, especially in the families Rosaceae and Myrtaceae. Dibenzofurans and derivatives from lichens and ascomycetes have been well reviewed, but dibenzofurans from all biological sources in nature have not been reviewed. In this review, dibenzofurans from all natural sources have been comprehensively … Read more...

Kidron G.J., Starinsky A. & Xiao B. (2024): The enigmatic enrichment of potassium and magnesium in runoff and floodwater in the Negev: Do biocrusts hold the key?, Science of The Total Environment, 911: 168753 [12 p.]

Hypothesizing that rock-dwelling (lithobionts) or soil (loess)-dwelling biocrusts may shed light on the phenomena, we conducted sprinkling experiments in the Negev Highlands. Sprinkling was conducted on 4 types of lithobionts: cyanobacteria which inhabit the south-facing bedrock (ENC), epilithic lichens, inhabiting the inclined (EPIi) and the flat (EPIf) north-facing bedrocks, and endolithic lichens (ENL) inhabiting south-facing boulders. Additional sprinkling took place on two types of soil biocrusts, … Read more...

Tälle M., Ranius T. & Öckinger E. (2023): The usefulness of surrogates in biodiversity conservation: A synthesis, Biological Conservation, 288: 110384 [11 p.]

Preserving biodiversity requires extensive information on species distributions and effectiveness of conservation actions. A surrogate approach, where a small number of species act as surrogates for broader groups of species, can simplify this task. Types of surrogates include indicator, umbrella, keystone and flagship species, and using diversity of higher taxonomic levels to represent species diversity. An overview of the empirical evidence of the usefulness of surrogates as a conservation tool … Read more...

Wilk K. & Lücking R. (2024): Quantitative integrative taxonomy informs species delimitation in Teloschistaceae (lichenized Ascomycota): the genus Wetmoreana as a case study, IMA Fungus, 15: 9 [42 p.]

The genus Wetmoreana was studied using quantitative integrative taxonomy methods to resolve the genus delimitation and explore its taxonomy diversity at the species level. As a result, the genus Fulgogasparrea is synonymized with Wetmoreana, and the latter includes 15 formally described species, one subspecies, and three further, thus far undescribed species: W. appressa, W. awasthii comb. nov., W. bahiensis sp. nov., W. brachyloba comb. nov., W. brouardii, W. chapadensis comb. nov., W. circumlobata … Read more...

Brenning M., Longstaffe F.J. & Fraser D. (2024): Variation in stable carbon (δ13C) and nitrogen (δ15N) isotope compositions along antlers of Qamanirjuaq caribou (Rangifer tarandus groenlandicus), Ecology and Evolution, 14: e11006 [18 p.]

Annual antler growth begins in the spring and is completed by late summer for male caribou (Rangifer tarandus groenlandicus) from the Qamanirjuaq herd (Nunavut, Canada), aligned with both the spring migration and a seasonal dietary shift. Antlers may provide a non-lethal means of studying short- and long-term changes in caribou ecology through incorporated isotopes of carbon (δ13C) and nitrogen (δ15N). We sampled the antlers of 12 male caribou from the Qamanirjuaq herd culled in September 1967. … Read more...

Łuniewski S., Rogowska W., Łozowicka B. & Iwaniuk P. (2024): Plants, microorganisms and their metabolites in supporting asbestos detoxification—A biological perspective in asbestos treatment, Materials, 17(7): 1644 [17 p.]

Many countries banned asbestos due to its toxicity, but considering its colossal use, especially in the 1960s and 1970s, disposing of waste containing asbestos is the current problem. Today, many asbestos disposal technologies are known, but they usually involve colossal investment and operating expenses, and the end- and by-products of these methods negatively impact the environment. This paper identifies a unique modern direction in detoxifying asbestos minerals, which involves using microorganisms … Read more...

Klasberg M. (2021): De opmars van rood dooiermos (Rusavskia elegans) in Maastricht onder de loep genomen. Lichenometrisch en ecologisch onderzoek naar een zuidelijke soort [Rusavskia elegans colonizes Maastricht – lichenometric and ecological investigation of a southern lichen species], Buxbaumiella, 121: 1–24

[in Dutch with English summary: ] In 2020, lichenometric research was performed on Elegant sunburst lichen (Rusavskia elegans) to reconstruct the colonization of Maastricht (Netherlands). Maastricht, in the southernmost tip of the Netherlands, lies in a hilly countryside and borders the Meuse (‘Maas’ in Dutch), a rain river. To be able to estimate the age of the populations, the first step was calibrating the growth rate. That was not an unnecessary action, as the growth rate of 1.9 … Read more...
