Vieira C., Hespanhol H., Portela A., Marques J. & Vila-Viçosa C. (2019): The Mediterranean in a Closet: Botany collections at the Herbarium of the Natural history and Science Museum of the University of Porto - Museu di Scientia Natural Porto, 2023: 1-1

The Herbarium of the Natural History and Science Museum of the University of Porto (MHNC-UP) (registered in the Index Herbariorum as PO Herbarium) is an active collection in continuous growth that contains about 100,000 herbarium specimens of fungi, lichens, algae, bryophytes, pteridophytes and vascular plants. The history of botany at Porto University is inseparable from the origins of the first specimens of bryophytes and lichens collected by Isaac Newton in 1848, in mainland Portugal. The majority … URL EndNote PDF Read more...

Rotter P., Purchart L. (eds.) (2023): Ekologie lesa. Jak se les mění a funguje - Brno: Mendelova univerzita v Brně, 647 p

Kniha představuje čtenáři les jako komplexní adaptivní systém. Oproti tradičnímu ekosystémovému pohledu jsou více zdůrazněny biotické interakce mezi členy této složité sítě. To se neobejde bez vysvětlení některých základních pojmů a fenoménů sítí vztahů v lesních ekosystémech. V těchto sítích vynikají některé druhy, či skupiny druhů, jako druhy klíčové nebo jako tzv. ekosystémoví inženýři. Tyto druhy, skupiny druhů, či dokonce celé fragmenty sítě … URL EndNote Read more...

(2023): New and Interesting Fungi. 6 - Fungal Systematics and Evolution, 11: 109–156

Three new genera, six new species, three combinations, six epitypes, and 25 interesting new host and / or geographical records are introduced in this study. New genera: Neoleptodontidium (based on Neoleptodontidium aquaticum), and Nothoramularia (based on Nothoramularia ragnhildianicola). New species: Acremonium aquaticum (from cooling pad water, USA, Cladophialophora laricicola (on dead wood of Larix sp., Netherlands), Cyphellophora neerlandica (on lichen on brick wall, Netherlands), Geonectria … URL EndNote Read more...

Acosta Hospitaleche C., García R., Pérez L.M. & Márquez G. (2023): Neoichnology of endolithic lichens: an update on the traces produced in fossil bones and teeth - Historical Biology, 35(7): 1175‒1185

The present contribution is motivated by the frequent occurrence of traces generated by lichens on the fossil record, the usual and erroneous attribution of them to plant roots, and the scarce information published about bioerosive damage caused by lichens. As a result, two different patterns were identified on the surface and inside the fossil bones and teeth. The first one is characterised by the presence of lines clearer than the rest of the surface, produced by the hyphae and interrupted … URL EndNote Read more...

Burt S.R., Harper J.K. & Cool L.G. (2023): A new depsidone from the neotricone-rich chemotype of the lichenised fungus Usnea fulvoreagens - Natural Product Research, 37(13): 2248‒2254

Individuals of Usnea fulvoreagens (Parmeliaceae, lichenised Ascomycota), a shrubby corticolous species that is widespread in Europe, East Asia and North America, produce medullary lichen acids in several distinct chemotypic patterns. One such chemotype reportedly contains an unidentified substance as the major secondary metabolite. We isolated this compound from Californian specimens of U. fulvoreagens and identified it as the rare depsidone neotricone. A co-occurring compound, conneotricone, was … URL EndNote PDF Read more...

Castañeta G., Sepulveda B., Vargas R., Garcia-Beltran O., Simirgiotis M. & Areche C. (2023): A sustainable application for the extraction of lichen metabolites from Usnea cornuta: nontargeted metabolomics and antioxidant activity - Natural Product Research, 37(12): 2076‒2082

In this study, isolation and purification of lichen substances from Usnea cornuta were performed using conventional solvents, green solvents and green technologies. In addition, several lichen compounds were tentatively identified by UHPLC/ESI/MS/MS and usnic acid, diffractaic and galbinic acids were quantified as well. Limonene, ethyl lactate and methanol, were compared regarding their extraction properties and antioxidant capacities, determined by DPPH, ORAC, and FRAP assays. In the ethyl … URL EndNote PDF Read more...

Nguyen H.-H., Duong T.-H., Nguyen T.V.A., Do T.-H., Pham D.-D., Nguyen N.-H. & Truong Nguyen H. (2023): α-Glucosidase inhibitory derivatives of protocetraric acid - Natural Product Research, 37(12): 1935‒1946

Lichen-derived depsidones have been a successful source for alpha-glucosidase inhibitory agents with numerous advantages. In this article, derivatives of protocetraric acids were designed and synthesised. Diels-Alder reaction, esterification, and Friedel-Crafts alkylation of protocetraric acid with different reagents under Lewis acid were performed. Eleven products were prepared, including 10 new compounds and parmosidone A. Among them, compounds 2–4 and 6 had the novel skeletons. The newly … URL EndNote PDF Read more...

Nguyen V.-K., Nguyen-Si H.-V., Devi A.P., Poonsukkho P., Sangvichien E., Tran T.-N., Yusuke H., Mitsunaga T. & Chavasiri W. (2023): Eumitrins F-H: three new xanthone dimers from the lichen Usnea baileyi and their biological activities - Natural Product Research, 37(9): 1480‒1490

The lichen Usnea baileyi is a fruticose lichen belonging to the Usnea genus. It is well known as a rich source of natural xanthone dimers and possesses various bioactivities. Nevertheless, the chemical investigation on this type of lichen is still rare as most of researches reported its components without structural elucidation. Herein, in the continuous study on this type of lichen, we further isolate xanthone dimers from the dichloromethane extract and explore three new xanthone dimers, eumitrins … URL EndNote PDF Read more...
