Santos A.M., Vitorino L.C., Cruvinel B.G., Ávila R.G., Vasconcelos Filho S.C., Batista P.F. & Bessa L.A. (2022): Impacts of Cd pollution on the vitality, anatomy and physiology of two morphologically different lichen species of the genera Parmotrema and Usnea, evaluated under experimental conditions - Diversity, 14(11): 926 [29 p.]

The heavy metal Cd accumulates in trophic chains, constituting a toxic element for photosynthesizing organisms, including the algal photobionts of lichen. Thus, as lichens respond differently to heavy metal toxicity, we hypothesized that the species Parmotrema tinctorum and Usnea barbata, commonly sampled in the Cerrado ecoregion, could be sensitive to Cd and, therefore, be used to biomonitor the dispersion of this metal. We also aimed to indicate the responsiveness of biological markers to Cd in … URL EndNote Read more...

Harnesk D. (2022): The decreasing availability of reindeer forage in boreal forests during snow cover periods: A Sámi pastoral landscape perspective in Sweden - Ambio, 51: 2508–2523

This paper argues that Sámi reindeer pastoralism in Sweden is highly stressed during the critical snow cover periods due to large-scale human interventions, especially forestry, and that these have over time significantly worsened the ecological conditions for natural grazingbased responses to changing snow conditions caused by climate change. Informed by a literature review, the paper conceptualises two, overlapping ecological dynamics that shape the availability of lichen as key forage … URL EndNote Read more...

Ortiz-Moreno M.L., Moncada B., Vasco-Palacios A.M., de Almeida R.F. & Gaya E. (2022): Fungi in Colombian and international biological collections - In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 189–207, Kew Publishing, Royal Botanic Gardens, Kew

Colombia ranks among the 17 countries considered megadiverse, hosting almost 10% of the planet’s biodiversity and only being surpassed by Brazil, a country seven times larger than Colombia. Unfortunately, fungi are mostly left out of these counts. One of the issues faced when attempting to report the fungal diversity in Colombia is the inability to account for the fungal specimens scattered in national and international collections, which are often not properly curated or digitised. In this … EndNote Read more...

Ai M., Zhong Q., Scheidegger C., Wang L. & Wang X. (2022): Revision of Dimelaena Norman (Caliciaceae, Ascomycota) species containing usnic acid reveals a new species and a new combination from China - Phytotaxa, 574(4): 259–272

Dimelaena tibetica is described as a species new to science, characterized by a grayish yellow surface, usually with a covering of white pruina, a crustose thallus, areolate at center, radiate-plicate at margin, adnate apothecia and lacking gyrophoric acid. It differs from other usnic acid-containing Dimelaena species by its plane marginal lobes and adnate apothecia. Based on the study of fresh specimens from the environment of the type locality, Dimelaena altissima is proposed as a new combination. … URL EndNote Read more...

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...

(eds), Catalogue of Fungi of Colombia, p. 209–424, Kew Publishing, Royal Botanic Gardens, Kew

chapter in book; it includes lichenicolous and lichenized fungi as well [bilingual in Spanish and English] A comprehensive checklist of the fungi known for Colombia is presented in this chapter. This checklist is one of the core outputs of the Useful Plants and Fungi of Colombia (UPFC) project, produced by a multinational team of researchers. The checklist includes supraspecific taxonomic ranks, accepted species and authors, synonyms and authors, common names, species origin (when available), … 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...

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...
