ten Veldhuis M.-., Ananyev G. & Dismukes G.C. (2020): Symbiosis extended: exchange of photosynthetic O2 and fungal-respired CO2 mutually power metabolism of lichen symbionts, Photosynthesis Research, 143: 287–299

Lichens are a symbiosis between a fungus and one or more photosynthetic microorganisms that enables the symbionts to thrive in places and conditions they could not compete independently. Exchanges of water and sugars between the symbionts are the established mechanisms that support lichen symbiosis. Herein, we present a new linkage between algal photosynthesis and fungal respiration in lichen Flavoparmelia caperata that extends the physiological nature of symbiotic co-dependent metabolisms, mutually … Read more...

Ranius T., Hämäläinen A., Sjögren J., Hiron M., Jonason D., Kubart A., Schroeder M., Dahlberg A., Thor G. & Jonsell M. (2019): The evolutionary species pool concept does not explain occurrence patterns of dead-wood-dependent organisms: implications for logging residue extraction, Oecologia, 191(1): 241-252

Emulation of natural disturbances is often regarded as a key measure to make forestry biodiversity-oriented. Consequently, extraction of logging residues is assumed to have little negative effect in comparison to extraction of dead wood mainly formed at natural disturbances. This is consistent with the evolutionary species pool hypothesis, which suggests that most species are evolutionary adapted to the naturally most abundant habitats. We tested this hypothesis for dead-wood-dependent macrofungi, … Read more...

Lücking R. (2020): Three challenges to contemporaneous taxonomy from a licheno-mycological perspective, Megataxa, 1(1): 78-103

This paper discusses three issues that challenge contemporaneous taxonomy, with examples from the fields of mycology and lichenology, formulated as three questions: (1) What is the importance of taxonomy in contemporaneous and future science and society? (2) An increasing methodological gap in alpha taxonomy: challenge or opportunity? (3) The Nagoya Protocol: improvement or impediment to the science of taxonomy? The importance of taxonomy in society is illustrated using the example of popular field … Read more...

Petelka J., Plagg B., Säumel I. & Zerbe S. (2020): Traditional medicinal plants in South Tyrol (northern Italy, southern Alps): Biodiversity and use, Journal of Ethnobiology and Ethnomedicine, 16: 74

Background Worldwide mountain regions are recognized as hotspots of ethnopharmacologically relevant species diversity. In South Tyrol (Southern Alps, Italy), and due to the region’s high plant diversity and isolated population, a unique traditional botanical knowledge of medicinal plants has flourished, which traces its history back to prehistoric times. However, changes in rural life and culture may threaten this unique biodiversity and cultural heritage. Our study aims to collect and analyze … Read more...

Sahin E., Dabagoglu Psav S., Avan I., Candan M., Sahinturk V. & Koparal A.T. (2019): Vulpinic acid, a lichen metabolite, emerges as a potential drug candidate in the therapy of oxidative stress–related diseases, such as atherosclerosis, Human and Experimental Toxicology, 38(6): 675–684

Vulpinic acid, a lichen compound, has been shown to have many beneficial effects and its medicinal value increases day by day. As in atherosclerosis, endothelial damage is the basis of many diseases. The aim of this study is to investigate the effects of vulpinic acid against oxidative stress damage induced by hydrogen peroxide (H2O2) in endothelial cells. In order to find the IC50 of H2O2 and the protective dose of vulpinic acid, methyl thiazolyldiphenyl tetrazolium bromide (MTT) assays were performed. … Read more...

Nyenda T., Gwenzi W., Piyo T.T. & Jacobs S.M. (2019): Occurrence of biological crusts and their relationship with vegetation on a chronosequence of abandoned gold mine tailings, Ecological Engineering, 139: 105559

Biological crusts (BCs) are soil ecological engineers critical in restoration yet their occurrence, and relationship with vegetation in a primary succession are poorly understood. The objectives of the study were: (1) to determine BC cover changes on a chronosequence and toposequence of tailings dumps and their correlation with vegetation structural and substrate attributes and (2) to determine vegetation community changes along a BC cover gradient. We hypothesized that: (1) BC cover significantly … Read more...

Moeslund J.E., Zlinszky A., Ejrnæs R., Brunbjerg A.K., Bøcher P.K., Svenning J.-. & Normand S. (2019): Light detection and ranging explains diversity of plants, fungi, lichens, and bryophytes across multiple habitats and large geographic extent, Ecological Applications, 29(5): e01907

Effective planning and nature management require spatially accurate and comprehensive measures of the factors important for biodiversity. Light detection and ranging (LIDAR) can provide exactly this, and is therefore a promising technology to support future nature management and related applications. However, until now studies evaluating the potential of LIDAR for this field have been highly limited in scope. Here, we assess the potential of LIDAR to estimate the local diversity of four species groups … Read more...

Sandström J., Bernes C., Junninen K., Lõhmus A., Macdonald E., Müller J. & Jonsson B.G. (2019): Impacts of dead wood manipulation on the biodiversity of temperate and boreal forests: A systematic review, Journal of Applied Ecology, 56(7): 1770-1781

Dead wood (DW) provides critical habitat for thousands of species in forests, but its amount, quality and diversity have been heavily reduced by forestry. Therefore, interventions aiming to increase DW might be necessary to support its associated biodiversity, even in protected forests, which may be former production forests. Our aim was to synthesize the current state of knowledge drawn from replicated experimental studies into solid quantitative evidence of the effects of DW manipulation on forest … Read more...

One of the most important problems is the study and conservation of biological diversity of our planet. The study of the flora species composition of any territory is the basis for the botanical and ecological research. One of the ways to control the environment is environmental monitoring. Fungi bacteria, complex symbiotic associations which include lichens, can be indicators of the state of the environment and its components. When predicting the state of the environment, especially air, representatives … Read more...

Cakmak K.C. & Gülçin İ. (2019): Anticholinergic and antioxidant activities of usnic acid-an activity-structure insight, Toxicology Reports, 6: 1273-1280

Usnic acid, as active dibenzofuran derivative, isolated and characterized from some lichen species. The aim of manuscript was to evaluate antioxidant, anticholinergic and antidiabetic potentials of usnic acid as an important natural product. Antioxidant profile of usnic acid determined by eight distinguishes bioanalytical antioxidant methods including 1,1-diphenyl-2-picrylhydrazyl (DPPH·), 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS[rad] +), superoxide anion radical (O2 [rad] −) … Read more...
