Óskarsdóttir G., Ágústsdóttir K., Thórisson S.G., Guðmundsdóttir G. & Jónsdóttir G.Á. (2024): Decadal vegetation changes in a subarctic-alpine ecosystem: Can effects of Iceland's largest hydropower reservoir, climate change, and herbivory be detected?, Applied Vegetation Science, 27(2): e12772 [15 p.]

Aims: While plot-based vegetation surveys provide means to precisely track changes in plant species abundance and distribution, ecosystems are continuously influenced by numerous drivers, confounding interpretation of monitoring results. Following the making of Iceland's largest hydropower reservoir in 2006, a decadal vegetation monitoring was set up. Relating our results to those of different types of environmental monitoring associated with the hydropower project, we aimed to gain insights into … Read more...

(2024): Classification of the high-rank syntaxa of the Central and Eastern Balkan dry grasslands with a new hierarchical expert system approach, Applied Vegetation Science, 27(2): e12779 [29 p.]

Aims: Developing a hierarchical classification system for classes, orders and alliances of the diverse dry grasslands of the Central and Eastern Balkan Peninsula and translating this into an electronic expert system (ES) for the automatic assignment of plots. Location: Serbia, Kosovo, North Macedonia, Bulgaria and northern Greece. Methods: We extracted 5734 plots from the Balkan Dry Grassland Database corresponding to eight classes of dry grasslands reported from the region, using the EuroVegChecklist … Read more...

Pouillé S., Talbot J., Tamalavage A.E., Kessler-Nadeau M.É. & King J. (2024): Impacts of Mineral Dust on Trace Element Concentrations (As, Cd, Cu, Ni and Pb) in Lichens and Soils at Lhù’ààn Mân’ (Yukon Territory, Canada), Journal of Geophysical Research: Biogeosciences, 129(6): e2023JG007927 [17 p.]

Dust is a mineral aerosol of the atmosphere that often contains trace elements such as As, Cd, and Pb. Lhù’ààn Mân’ (Kluane Lake), located in southwestern Yukon, is a region of frequent dust activity. In 2016, the lake level fell due to a dramatic decrease in inflow from glacier meltwater, and the delta of the lake became an important source of dust to surrounding ecosystems. To determine the impacts of dust deposition on vegetation and soil trace element concentrations and characteristics, … Read more...

Liao K., Chen C., Ye W., Zhu J., Li Y., She S., Wang P., Tao Y., Lv A., Wang X. & Chen L. (2024): The adaptability, distribution, ecological function and restoration application of biological soil crusts on metal tailings: A critical review, Science of the Total Environment, 927: 172169 [13 p.]

A large amount of metal tailings causes many environmental issues. Thus, the techniques for their ecological restoration have garnered extensive attention. However, they are still in the exploratory stage. Biological soil crusts (BSCs) are a coherent layer comprising photoautotrophic organisms, heterotrophic organisms and soil particles. They are crucial in global terrestrial ecosystems and play an equal importance in metal tailings. We summarized the existing knowledge on BSCs growing on metal tailings. … Read more...

Winkler S., Beylich A.A., Laute K., Matthews J.A., Mourne R.W. & Wilson P. (2024): Implications of an Early Holocene climax in solifluction and related periglacial activity on Juvflye, Jotunheimen (southern Norway), as revealed by Schmidt-hammer exposure-age dating, Geomorphology, 458: 109247 [25 p.]

Schmidt-hammer exposure-age dating (SHD) was applied to ~180 medium- to large-scale solifluction features on the northern edge of Juyflye, Jotunheimen (southern Norway) using an electronic Schmidt-hammer (RockSchmidt) and an improved local SHD age-calibration equation. Age estimates from four different types of solifluction landforms were analysed and compared with those from recalibrated estimates from patterned ground previously investigated on Juvflye. Average SHD-age estimates are c. 9.8 and … Read more...

Zhou Z., Li G., Gao L., Zhou Y., Xiao Y., Bi H. & Yang H. (2024): Lichen pectin-containing polysaccharide from Xanthoria elegans and its ability to effectively protect LX-2 cells from H2O2-induced oxidative damage, International Journal of Biological Macromolecules, 265(1): 130712 [14 p.]

Xanthoria elegans, a drought-tolerant lichen, is the original plant of the traditional Chinese medicine “Shihua” and effectively treats a variety of liver diseases. However, thus far, the hepatoprotective effects of polysaccharides, the most important chemical constituents of X. elegans, have not been determined. The aim of this study was to screen the polysaccharide fraction for hepatoprotective activity by using free radical scavenging assays and a H2O2-induced Lieming Xu-2 cell (LX-2) oxidative … Read more...

Andrzejowska A., Hájek J., Puhovkin A., Harańczyk H. & Barták M. (2024): Freezing temperature effects on photosystem II in Antarctic lichens evaluated by chlorophyll fluorescence, Journal of Plant Physiology, 294: 154192 [10 p.]

This study explores and compares the limits for photosynthesis in subzero temperatures of six Antarctic lichens: Sphaerophorus globosus, Caloplaca regalis, Umbilicaria antarctica, Pseudephebe minuscula, Parmelia saxatilis and Lecania brialmontii combining linear cooling and chlorophyll fluorescence methods. The results revealed triphasic S-curves in the temperature response of the maximum quantum yield (FV/FM) and effective quantum yield of photosystem II (ΦPSII) for all species. All investigated … Read more...

Tingstad L., Sandercock B. & Nybø S. (2024): Steep declines in radioactive caesium after 30 years of monitoring alpine plants in mountain areas of central Norway, Journal of Environmental Radioactivity, 272: 107352 [9 p.]

The Chernobyl accident exposed large areas of northern Europe to radiocaesium (137Cs). We investigated temporal and spatial variation in concentrations of radiocaesium among five functional groups of alpine plants at two mountain areas in central Norway over a 31-year period from 1991 to 2022. Average concentrations of radiocaesium were initially high in lichens and bryophytes at around 4600–6400 Bq/kg dry weight during 1991–1994 but then decreased dramatically over three decades to current concentrations … Read more...

Edible lichens are nutritious sources of health-promoting bioactive compounds utilized as ethnic foods and traditional medicine for ages and documented across universal pharmacopoeia. The nutritional, pharmacological and organoleptic features of lichen research are increasing, and new perspectives on its applications allow the development of novel functional foods and drugs. This review highlights the secondary metabolites of edible lichen, biological activities, and major applications in the pharma … Read more...
