Wang H., Xuan M., Huang C. & Wang C. (2022): Advances in research on bioactivity, toxicity, metabolism, and pharmacokinetics of usnic acid in vitro and in vivo - Molecules, 27(21): 7469 [22 p.]

Lichens are among the most widely distributed plants on earth and have the longest growth cycle. Usnic acid is an abundant characteristic secondary metabolite of lichens and the earliest lichen compound used commercially. It has diverse pharmacological activities, such as anti-inflammatory, antibacterial, antiviral, anticancer, antioxidant, and photoprotective effects, and promotes wound healing. It is widely used in dietary supplements, daily chemical products (fodder, dyes, food, perfumery, and … URL EndNote Read more...

Tonteri T., Hallikainen B., Merilä P., Miina J., Rautio P., Salemaa M. & Tolvanen A. (2022): Response of ground macrolichens to site factors, co-existing plants and forestry in boreal forests - Applied Vegetation Science, 25: e12690 [15 p.]

Aim: Ground lichens have declined in boreal and temperate Europe. The potential causes of the decline were explored by analysing the response of lichen cover to forest management, site and stand variables as well as co-existing plants in different boreal vegetation subzones. Location: Finland. Methods: Understorey vegetation was surveyed on a systematic network of 1721 sample plots in forests on mineral soil. The response of macrolichen cover to explanatory variables was analysed by generalised … URL EndNote Read more...

Reding J.M., Davies G.M. & Klips R.A. (2022): Rock climbing disturbance severity and abiotic gradients interact to determine cryptogam diversity and community structure - Applied Vegetation Science, 25: e12680 [11 p.]

Questions: Plant communities are shaped by interactions between natural and anthropogenic disturbances and underlying environmental conditions. We asked how disturbance by rock climbing alters patterns of cryptogam species diversity and composition along elevational abiotic gradients. Location: Red River Gorge, Kentucky, United States of America. Methods: Surveying was completed within 19 climbing routes on sandstone “slabs.” Quadrats were placed at three different vertical positions (elevations) … URL EndNote Read more...

(2022): The biodiversity of birch stands in agricultural landscapes of Estonia is associated with past land use, restoration approach, site and landscape variables - Applied Vegetation Science, 25: e12678 [15 p.]

Questions: Abandonment of agricultural land followed by tree planting or natural regeneration has increased forest area in Europe. We asked how restoration approach, past land use, site and landscape variables affected the richness and composition of vascular plants (field and shrub layers), bryophytes and lichens in middle-aged forests. Location: Thirty-three birch stands in Estonia. Methods: Data were collected from stands on former agricultural land that originated from plantations (PL-A) … URL EndNote Read more...

Mendili M., Khadhri A., Jemâa J.M.-B., Andolfi A., Tufano I., Aschi-Smiti S. & DellaGreca M. (2022): Anti-inflammatory potential of compounds isolated from Tunisian lichens species - Chemistry and Biodiversity, 19: e202200134 [10 p.]

The lichen’s special symbiotic structure enables it to produce bioactive substances. They have historically been recognized for their aesthetic and medicinal benefits. Furthermore, in recent years, they have performed in various fields, including perfumery, dyeing, and pharmacology due to their rich secondary metabolites. From our study, four compounds were isolated from organic extracts of Parmotrema hypoleucinum, Roccella phycopsis, and Xanthoria parietina and identified by spectroscopic … URL EndNote Read more...

Grudzińska M., Paśko P., Wróbel-Biedrawa D., Podolak I. & Galanty A. (2022): Antimelanoma potential of Cladonia mitis acetone extracts – Comparative in vitro studies in relation to usnic acid content - Chemistry and Biodiversity, 19: e202200408 [6 p.]

In this study, the cytotoxic activity of acetone extracts of Cladonia mitis was assessed with respect to the content of usnic acid, a secondary metabolite commonly present in this species. Following quantitative HPLC analysis of the extracts, usnic acid was isolated by preparative chromatography. The study of cytotoxic activity was performed using the MTT test on three melanoma cell lines – HTB140, A375 and WM793. The selectivity of action was also assessed by comparing the effect towards normal … URL EndNote Read more...

A refined, contemporary definition for a broadening research community - Biological Reviews, 97: 1768–1785

Studies of biological soil crusts (biocrusts) have proliferated over the last few decades. The biocrust literature has broadened, with more studies assessing and describing the function of a variety of biocrust communities in a broad range of biomes and habitats and across a large spectrum of disciplines, and also by the incorporation of biocrusts into global perspectives and biogeochemical models. As the number of biocrust researchers increases, along with the scope of soil communities defined as … URL EndNote Read more...

Concostrina-Zubiri L., Prieto M., Hurtado P., Escudero A. & Martínez I. (2022): Functional diversity regulates the effects of habitat degradation on biocrust phylogenetic and taxonomic diversities - Ecological Applications, 32: e2599 [14 p.]

Biocrusts are major contributors to dryland diversity, functioning, and services. However, little is known about how habitat degradation will impact multiple facets of biocrust diversity and measurable functional traits. We evaluated changes in taxonomic, functional, and phylogenetic diversity of biocrust-forming lichens along a habitat degradation gradient related to the presence of linear infrastructure (i.e., a road) and a profound agricultural driven transformation. To do so, we selected 50 remnants … URL EndNote Read more...

Spribille T., Resl P., Stanton D.E. & Tagirdzhanova G. (2022): Evolutionary biology of lichen symbioses - New Phytologist, 234: 1566–1582

Tansley review. Lichens are the symbiotic outcomes of open, interspecies relationships, central to which are a fungus and a phototroph, typically an alga and/or cyanobacterium. The evolutionary processes that led to the global success of lichens are poorly understood. In this review, we explore the goods and services exchange between fungus and phototroph and how this propelled the success of both symbiont and symbiosis. Lichen fungal symbionts count among the only filamentous fungi that expose … URL EndNote Read more...
