Khan M.S., Yang K., Liu Z., Zhou L., Liu W., Lin S., Wang X. & Shang C. (2023): Microorganisms involved in the biodegradation and microbiological corrosion of structural materials - Coatings, 13(10): 1683 [14 p.]

Microbiologically influenced corrosion (MIC) is the process of material degradation in the presence of microorganisms and their biofilms. This is an environmentally assisted type of corrosion, which is highly complex and challenging to fully understand. Different metallic materials, such as steel alloys, magnesium alloys, aluminium alloys, and titanium alloys, have been reported to have adverse effects of MIC on their applications. Though many researchers have reported bacteria as the primary culprit … URL EndNote PDF Read more...

Castañeta G., Villagomez R., Salamanca E., Canaviri-Paz P., Bravo J.A., Vila J.L., Bárcenas-Pérez D., Cheel J., Sepúlveda B., Giménez A. & Areche C. (2023): Microwave-assisted semisynthesis and leishmanicidal activity of some phenolic constituents from lichens - Separations, 10(10): 524 [15 p.]

Leishmaniasis is considered one of the most untreated tropical diseases in the world. In this study, we investigated the in vitro leishmanicidal activity and cytotoxicity of various isolated lichen substances, including atranorin (1), usnic acid (2), gyrophoric acid (3), salazinic acid (4), galbinic acid (5), and parietin (6), and some semi-synthetic imine derivatives of usnic acid (7, 8, 9) and atranorin (10, 11, 12, 13). Imine condensation reactions with hydrazine and several amines were assisted … URL EndNote PDF Read more...

Vondrák J., Svoboda S., Košnar J., Malíček J., Šoun J., Frolov I., Svensson M., Novotný P. & Palice Z. (2023): Martin7: a reference database of DNA barcodes for European epiphytic lichens and its taxonomic implications - Preslia, 95: 311–345

Molecular identification of organisms is now a common practice and, increasingly, species are identified from environmental samples. However, for most organisms, we still lack comprehensive reference databases of DNA barcodes to identify the sequences produced. We present a near-complete database of ITS and mtSSU barcodes, named Martin7, for accurate molecular identification of epiphytic lichens (mycobionts) of central Europe. New data were obtained by Sanger and PacBio sequencing. We obtained 907 … URL EndNote PDF Read more...

Ossowska E.A. (2023): Notes on sorediate Parmelia species in North America with the first records of P. asiatica and P. barrenoae - Phytotaxa, 619(2): 152–160

The first record of Parmelia asiatica from North America is presented. The species differs from other sorediate Parmelia taxa in having narrow, sublinear lobes with circular or semicircular, terminal or marginal soralia. New records and earlier data together suggest that P. asiatica may be a more common taxon in the Northern Hemisphere than previously reported. Additionally, the first record of P. barrenoae from Canada and the central states of the USA is presented. Notes on similar sorediate … URL EndNote Read more...

Bačkor M., Goga M., Ručová D., Urminská D., Bačkorová M. & Klejdus B. (2023): Allelopathic effects of three lichen secondary metabolites on cultures of aposymbiotically grown lichen photobionts and free-living alga Scenedesmus quadricauda - South African Journal of Botany, 162: 688–693

In the present work, we studied the influence of lichen secondary metabolites (evernic acid, orcinol, usnic acid) on selected species of algae: Trebouxia erici, photobiont of lichen Cladonia cristatella producing typical lichen secondary metabolites, Coccomyxa solorinae-saccatae, photobiont of lichen Solorina saccata which does not produce typical secondary metabolites of lichens, and free-living alga Scenedesmus quadricauda. For the determination of the cytotoxic effects of these compounds, algae … URL EndNote PDF Read more...

Copeland S.M., Condon L.A., Rosentreter R., Miller J.E.D. & Kahn-Abrams M. (2023): Biocrusts Indicators of Livestock Grazing Effects on Soil Stability in Sagebrush Steppe: A Case Study from a Long-Term Experiment in the Northern Great Basin - Rangeland Ecology and Management, 91: 82–86

Biocrusts are sensitive to changes in livestock grazing intensity in arid rangelands and may be useful indicators of ecosystem functions, particularly soil properties like soil stability, which may suggest the potential for soil erosion. We compared biocrust community composition and surface soil stability in a big sagebrush (Artemisia tridentata) steppe rangeland in the northwestern Great Basin in several paired sites, with or without long-term cattle grazing exclusion, and similar soils (mostly … URL EndNote PDF Read more...

Su T.-H., Zhou C.-Y., Sun W., Jia T., Hu T., Li Z.-F., Pu X.-Y., Lu Z.-Y. & Li S. (2023): Greater differentiation in nitrogen sources is essential for co-occurring epiphytes under low-nitrogen canopy conditions - Environmental and Experimental Botany, 215: 105509 [12 p.]

Acquiring enough nitrogen (N) to support their life processes in nutrient-poor canopies is a crucial challenge for epiphytes. When different epiphytes coexist in the same environment, they may use different strategies to acquire N. In this study, we employed stable isotope analysis to explore N acquisition and differentiation among co-occurring epiphytes in a subtropical forest in Southwest China. We found that functional group was the most important factor influencing N and 15N natural abundance … URL EndNote PDF Read more...

Randriamananjara M.A., Fenton N.J. & DesRochers A. (2023): How does understory vegetation diversity and composition differ between monocultures and mixed plantations of hybrid poplar and spruce? - Forest Ecology and Management, 549: 121434 [14 p.]

Although monocultures are important for timber production, they are often associated with lower biological diversity than mixtures. Thus, mixed plantations have been suggested as a way to enhance biodiversity because of their inherent compositional diversity. However, the effects of monocultures versus mixtures on understory diversity and composition can vary in different ecosystems. The objective of this study was to assess how monocultures and mixed plantations influence understory vegetation diversity … URL EndNote PDF Read more...

Medison R.G., Jiang J., Medison M.B., Tan L.-T., Kayange C.D.M., Sun Z. & Zhou Y. (2023): Evaluating the potential of Bacillus licheniformis YZCUO202005 isolated from lichens in maize growth promotion and biocontrol - Heliyon, 9(10): e20204 [14 p.]

Lichens exist in an organismal organization of mycobiont, photobiont, and non-photoautotrophic bacteria. These organisms contribute to the growth of lichens even in poor nutrition substrates. However, studies on the isolation and application of non-photoautotrophic bacteria in plant growth and biocontrol are scanty. Therefore, a study was conducted to isolate and evaluate the potential of non-photoautotrophic bacteria from lichen tissues in maize plant growth promotion and biocontrol of plant pathogens … URL EndNote PDF Read more...

Qiu D., Bowker M.A., Xiao B., Zhao Y., Zhou X. & Li X. (2023): Mapping biocrust distribution in China's drylands under changing climate - Science of The Total Environment, 905: 167211 [12 p.]

Biological soil crusts (biocrusts) are widely distributed in global drylands and have multiple significant roles in regulating dryland soil and ecosystem multifunctionality. However, maps of their distribution over large spatial scales are uncommon and sometimes unreliable, because our current remote sensing technology is unable to efficiently discriminate between biocrusts and vascular plants or even bare soil across different ecosystem and soil types. The lack of biocrust spatial data may limit … URL EndNote PDF Read more...
