Diaz-Allen C., Spjut R.W., Kinghorn A.D. & Rakotondraibe H.L. (2021): Prioritizing natural product compounds using 1D-TOCSY NMR spectroscopy, Trends Org Chem, 22: 99-114

Natural product (NP) secondary metabolites are designed evolutionarily to have biological effects in other organisms for defense and the mediation of ecological interactions. Their structural complexity and diversity complement biological systems, allowing them to display unique bioactivities. Although more than half of all pharmaceuticals stem from NPs, pharmaceutical companies have reduced NP-based drug discovery programs due to various time and cost-consuming pitfalls; the re-isolation of already … Read more...

Campbell P.C., Tong D., Saylor R., Li Y., Ma S., Zhang X., Kondragunta S. & Li F. (2022): Pronounced increases in nitrogen emissions and deposition due to the historic 2020 wildfires in the western U.S, Science of the Total Environment, 839: 156130

Wildfire outbreaks can lead to extreme biomass burning (BB) emissions of both oxidized (e.g., nitrogen oxides; NOx = NO+NO2) and reduced form (e.g., ammonia; NH3) nitrogen (N) compounds. High N emissions are major concerns for air quality, atmospheric deposition, and consequential human and ecosystem health impacts. In this study, we use both satellite-based observations and modeling results to quantify the contribution of BB to the total emissions, and approximate the impact on total N deposition … Read more...

Bargali H., Kumar A. & Singh P. (2022): Plant studies in Uttarakhand, Western Himalaya–A comprehensive review, Trees, Forests and People, 8: 100203

The Indian Himalayan Region harbor about half of the flowering plant species recorded in India, of which nearly 30% species are endemic. The state of Uttarakhand, also known as the ‘herbal state of India,’ harbors more than 5000 species of vascular plants, of which one-third species have medicinal uses. Thus, considering the immense floral, ecological, and ethno-botanical values, the current communication aims to conduct an extensive review of scientific research on such aspects in this Himalayan … Read more...

Bajpai R., Paul R.R., Pandey U., Singh C.P., Kumar A., Uniyal S.K., Pande V. & Upreti D.K. (2022): Refining the picture of lichen biota of Himachal Pradesh together with new distributional records to the state, Nelumbo, 64(1): 171-247

Himachal Pradesh (HP) is one of the biodiversity rich states of Western Himalaya, however meagre information is available regarding lichen biota of this state. In the present study an attempt has been made to provide an updated list of lichens from HP. The list is based on recent collections and some previous available literature made by the authors during the last one decade. A total of 714 species of lichens belonging to 189 genera and 49 families are reported, of which 15 species are new addition … Read more...

Antoninka A., Chuckran P.F., Mau R.L., Slate M.L., Mishler B.D., Oliver M.J., Coe K.K., Stark L.R., Fisher K.M. & Bowker M.A. (2022): Responses of Biocrust and Associated Soil Bacteria to Novel Climates Are Not Tightly Coupled, Front Microbiol, 13: 821860

Climate change is expanding drylands even as land use practices degrade them. Representing ∼40% of Earth's terrestrial surface, drylands rely on biological soil crusts (biocrusts) for key ecosystem functions including soil stability, biogeochemical cycling, and water capture. Understanding how biocrusts adapt to climate change is critical to understanding how dryland ecosystems will function with altered climate. We investigated the sensitivity of biocrusts to experimentally imposed novel climates … Read more...

Angulo M., Guerra K., Ramos A., Monreal-Escalante E., Martínez E. & Angulo C. (2022): Potential assessment of probiotic Cystobasidium benthicum LR192 strain in mice, Arch Microbiol, 204(12): 729

Antibiotic bacterial resistant is a huge concern worldwide and probiotics offer an alternative to mitigate it. This study explores Cystobasidium benthicum LR192 as possible probiotic through microbiological and immunological analyses in mouse model. C. benthicum LR192 was isolated from lichens in a hyperarid environment in Baja California Sur, Mexico. First, microbiological analysis was assessed using 1 × 10(5) CFU/mL in YM broth: resistance to 1% of bile salts and pH of 2, 3 and 5 (control). … Read more...

Yakushev A.V., Velichko N.V., Fedorov-Davydov D.G., Mergelov N.S., Lupachev A.V., Rabochaya D.E., Belosokhov A.F. & Soina V.S. (2022): Organization of Microbial Communities in Soils: Experiment with Fouling Glasses in Extreme Terrestrial Landscapes of Antarctica, Eurasian Soil Science, 55(12): 1770-1785

The study of microbial complexes in organo-accumulative horizons of Antarctic soils (Cryosols, Leptosols) at the Larsemann Hills and Schirmacher oases and on King George Island has been carried out by the fouling glass method. This method allows one to study the taxonomic composition of microorganisms, features of their morphology, inter-organism interactions, and spatial organization of the complex of microorganisms, as well as to simulate the processes of colonization of mineral surfaces. The investigated … Read more...

Salah M.B., Aouadhi C., Mendili M. & Khadhri A. (2022): Phenolic Content, Antioxidant, Antibacterial, and Anti-Acetylcholinesterase Activities of Biosynthesized and Characterized Silver Nanoparticles from Tunisian Medicinal Lichen Species, Int J Med Mushrooms, 24(6): 79-93

Lichens produce a myriad of bioactive compounds that can be exploited as reducing and capping agents in the green process of synthesizing nanoparticles. In this study, we exploit a simple, environmentally safe method for synthesizing silver nanoparticles (AgNPs), using aqueous extracts of three lichen species (Lobaria pulmonaria, Ramalina farinacea, and Evernia prunastri) for the first time. Characterization showed that the three lichen species selected could be perfectly suitable as reducing agents … Read more...

Retallack G.J. (2022): Ordovician-Devonian lichen canopies before evolution of woody trees, Gondwana Research, 106: 211-223

Devonian evolution of woodlands has been envisaged as a protracted increase in size of vascular plants, which can be reconstructed from fossil stumps and trunks. However, Late Silurian and Early Devonian nematophytes such as Prototaxites would have towered over land plants, including vascular plant trees, in the same fossil plant assemblage, until finally overtaken by vascular land plants during the Early Carboniferous. Nematophytes lack tissues of vascular plants, and some have spherical photobionts … Read more...
