Tatipamula V.B. & Vedula G.S. (2019): Antimicrobial and anti-tubercular activities of isolates and semi-synthetic derivatives of lichen Ramalina leiodea (Nyl.) Nyl., Journal of the Serbian Chemical Society, 84(6): 555-562

The chemical investigation of lichen Ramalina leiodea (Nyl.) Nyl. yielded five known metabolites, i.e., usnic acid (1), ethyl everninate (2), scrobiculin (3), methyl 2,6-dihydroxy-4-methylbenzoate (4) and 4-[(2-hydroxy-4-methoxy-6-propylbenzoyl)oxy]-2-methoxy-6-propylbenzoic acid (5). To develop compound libraries on 4, a series of semi-synthetic derivatives was prepared (4a––e). All the metabolites and semi-synthetic analogues were screened for antimicrobial and anti-tubercular activities. The … Read more...

Susanti A.E., Ratnakomala S., Mangunwardoyo W. & Lisdiyanti P. (2019): Antimicrobial activity of lichens-associated actinomycetes strain LC-23, ACM International Conference Proceeding Series, : 91-96

Actinomycetes known as the largest antibiotic producer that has a broad range habitat. Research has been done to find a new antibiotic from the various habitats of actinomycetes. Lichens was the symbiotic structure of alga and fungi known as the ecological niche of various kinds of microbes including actinomycetes. The aim of this study in deep of isolate strain LC-23 for production of antimicrobial, characterize the metabolite profile of the ethyl acetate extract and identification based on 16S … Read more...

Mayor A. (2025): Can geology explain the deadly reputation of the Styx River and shed light on the death of Alexander the Great?, Geoheritage, 17: 92 [15 p.]

Modern discoveries of two naturally occurring toxins that thrive in limestone-rich environments offer clues to understanding how the Styx (Mavroneri) River received its nefarious reputation in antiquity. In Greek myth, the Styx was the entrance to the Underworld. The Styx was believed to be poisonous, dangerous even to the gods who swore oaths by its waters. After the death of Alexander the Great in 323 BCE, rumors arose that he had been deliberately poisoned by the water of the Styx. This paper … Read more...

Põldveer E., Paluots T., Korjus H., Arumäe T., Kangur A. & Laarmann D. (2025): Ecological quality and structural diversity of Western Taiga habitat (*9010) in Estonia’s Natura 2000 network, Environmental Monitoring and Assessment, 197: 482 [24 p.]

Western Taiga habitat (*9010) plays the key role in the Natura 2000 network in Estonia. Natura 2000 is a European Union nature conservation area network aimed to safeguard the long-term survival of Europe’s unique flora and fauna. This study examines the Western Taiga habitat within mixed oligo-mesotrophic and mesotrophic forests on mineral soils with a minimum age of 70 years, providing a comprehensive assessment of the habitat’s current condition. The assessment includes ecological quality … Read more...

Sparrius L.B., Duijsens M.J., Kollen D., Riksen M.J.P.M. & van Strien A.J. (2025): Nitrogen deposition increases spontaneous forest establishment and loss of lichen vegetation in inland dune areas across the Netherlands, Applied Vegetation Science, 28(2): e70029 [8 p.]

Questions (1) How much of the inland dune habitat has been transformed into spontaneous forest across the Netherlands between 2007 and 2018? (2) Is there a spatial correlation between nitrogen deposition and changes in vegetation? (3) What changes could be observed in the cover of lichen vegetation and the invasive bryophyte Campylopus introflexus within this period? (4) What measures can be taken to counteract the effect of spontaneous forest establishment? Location Inland dune sites across … Read more...

Waterworth S.C., Egbert S., Sorensen J., O'Keefe B.R. & Beutler J.A. (2025): A biosynthetic and taxonomic atlas of the global lichen holobiont, Environmental Microbiology, 27: e70112 [19 p.]

Lichens are pioneer species in several ecosystems, and as such are found in a variety of geographic regions and environments. Here, inspection of metagenomic data from 794 lichen samples from 34 countries reveals the presence of a complex holobiont harbouring remarkable biosynthetic capabilities, particularly in the bacterial consortia, a component that has been somewhat underappreciated. While bacteria were consistently present, their abundance varied among lichen taxa. Common bacterial genera included … Read more...
