Zorer R., Türk R., Stocker-Wörgötter E. (1997): Resynthesis of the lichen Cladonia fimbriata from the axenic cultures of the isolated symbionts - Bibl. Lichenol., 67: 85-89

Successful resynthesis was achieved between the mycobiont of Cla- donia fimbriata and its Trebouxia photobiont. High concentration of fumarprotocetraric acid was detected by TLC analysis of acetone extracts from the synthesized lichen thallus and podetia. The success of the resynthesis experiments depends on the light and temperature conditions and especially on the humidity. The alternation of moist and dry' periods is necessary for the development and for the morphogenesis of the lichen and probably … Read more...

Zorn S., Carvalho A., Bento H., Gambarato B., Pedro G., da Silva A., Gonçalves R., Da Rós P. & Silva M. (2022): Use of fungal mycelium as biosupport in the formation of lichen-like structure: recovery of algal grown in sugarcane molasses for lipid accumulation and balanced fatty acid profile - Membranes, 12(3): 258 [15 p.]

In this study, a lichen-like structure was obtained through the production of a unique biomass, formed by algae cells of Scenedesmus obliquus adhering to the mycelium of filamentous fungal Mucor circinelloides. This structure was composed in two steps; in the first one, microalgal cells and spores were incubated separately, and in the second one, after 72 h of growth, isolated, mature mycelium was harvested and added to cell culture. For spores’ incubation, a culture medium containing only 2 g·L−1 … Read more...

Zorrilla J.G., D’Addabbo T., Roscetto E., Varriale C., Catania M.R., Zonno M.C., Altomare C., Surico G., Nimis P.L. & Evidente A. (2022): Antibiotic and nematocidal metabolites from two lichen species collected on the Island of Lampedusa (Sicily) - International Journal of Molecular Sciences, 23(15): 8471 [12 p.]

The antibiotic and nematocidal activities of extracts from two coastal lichen species collected on Lampedusa Island (Sicily), Ramalina implexa Nyl. and Roccella phycopsis Ach., were tested. Methyl orsellinate, orcinol, (+)-montagnetol, and for the first time 4-chlororcinol were isolated from Roccella phycopsis. (+)-Usnic acid was obtained from Ramalina implexa. The crude organic extract of both lichen species showed strong antibiotic activity against some bacterial species and nematocidal activity. … Read more...

Zotz G. (2017): Growth of Rhizocarpon geographicum in the summit region of Volcan Barú, Panama - Lichenologist, 49(5): 535–538

The crustose lichens of the genus Rhizocarpon are among the most widely distributed species on rock surfaces worldwide (Armstrong 2011, 2016). Thalli of this species are characterized by yellow-green lichenized areolae on the surface of a non-lichenized fungal hypotha- llus, which forms a dark marginal ring. Rhizocarpon species typically grow very slowly and reach a considerable age, characteristics that have been exploited in numerous studies by earth scientists and archaeologists using these lichens … Read more...

Zotz G. & Bader M.Y. (2008): Epiphytic Plants in a Changing World-Global: Change Effects on Vascular and Non-Vascular Epiphytes - Progress in Botany, 70: 147-170

Abstract: Epiphytes have been called particularly vulnerable to climate change because of their existence at the interface of vegetation and atmosphere. We review the available evidence for this notion and put our analysis into the larger context of human-induced changes in general. Besides climate change, land use changes adversely affect epiphytes, while other factors, e.g. biotic exchange, are of lesser importance in this life form. Both land use change and climate change primarily affect … Read more...

Zotz G. & Cascante-Marín A. (2024): Life on the wire—plant growth on power lines in the Americas - Diversity, 16(9): 573 [13 p.]

There are a number of rather anecdotal reports of plant growth on power cables in the Americas, but until now there has been no systematic attempt to gauge the geographical extension of this phenomenon nor a documentation of the diversity of species found there. Using observations from the participatory science data platform iNaturalist and the scientific literature, we document almost 700 occurrences of more than 40 species of vascular plants and three lichen species on power cables with a geographical … Read more...

Zotz G. & Winter K. (1994): Photosynthesis and carbon gain of the lichen, Leptogium azureum, in a lowland tropical forest - Flora, 189: 179–186

CO2 gas exchange and microclimatic conditions of Leptogium azureum (Sw. ex Ach.) Mont., a foliose lichen, were investigated in the lowland tropical forest of Barro Colorado Island, Panama. Thalli growing epiphytically in the forest canopy or epilithically on boulders in the understory were studied. Under the prevailing temperature and humidity conditions, thallus water contents were generally high during the night, resulting in high rates of respiration. Daytime net CO2 uptake was restricted by low … Read more...
