Aceto M., Calà E., Agostino A., Fenoglio G., Idone A., Porter C. & Gulmini M. (2017): On the identification of folium and orchil on illuminated manuscripts - Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 171: 461–469

The identification of the two purple dyes folium and orchil has rarely been reported in the analysis of painted artworks, especially when analysing illuminated manuscripts. This is not consistent with the fact that ancient literary sources suggested their use as substitutes for the more expensive Tyrian purple dye. By employing non-invasive spectroscopic techniques, the present work demonstrates that these dyes were actually widely used in the production of ancient manuscripts. By employing UV–visible … EndNote Read more...

Ackerman R.E. (1964): Lichens and the patination of chert in Alaska - American Antiquity, 29(3): 386-387

The exposed surfaces of stone artifacts from the Security Cove site, Alaska, were altered by the mechanical/chemical activity of crustose lichens. This factor should be considered in patination studies carried out in regions where lichens are known to occur. The activity of lichens and the resultant effect on artifact surfaces is discussed and illustrated in two figures. EndNote Read more...

Ackermann S., Amelung W. & Löffler J. (2015): Additional nitrogen in arctic-alpine soils and plants—a pilot study with 15NO3- equation image and 15NH4+ equation image fertilization along an elevation gradient - Journal of Plant Nutrition and Soil Science, 178(6): 861–867

Nitrogen (N) deposition has been increasing in alpine ecosystems, but its fate in soils and plants remains unclear. We assumed that the increased N load will be efficiently retained in alpine ecosystems but that the degree of N use efficiency changes with elevation. Thus, we performed a 3-year 15N tracer experiment, in which we added 1 g m−2 of either NH415NO3 or 15NH4NO3 fertilizer to a plot of 1 m2 in size at three elevations. Composite soil samples and aboveground plant material from lichens, … 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...

Acosta Hospitaleche C., Márquez G., Pérez L.M., Rosato V. & Cione A.L. (2011): Lichen bioerosion on fossil vertebrates from the Cenozoic of Patagonia and Antarctica - Ichnos, 18: 1-8

Different traces occur on fossil bones and teeth coming from the Early Miocene Gaiman Formation (Patagonia, Argentina). Most traces were attributed to the action of terrestrial and marine predators and scavengers. However, other traces on bones and teeth from this unit and one tooth from the Eocene La Meseta Formation (Antarctica) are attributed to chemical corrosion by lichens in recent times, that is, in a very late diagenetic time. The living lichens and calcium oxalate deposits occurring … EndNote Read more...

(2016): Fungi and lichens recorded during the cryptogam symposium on natural beech forests, Slovakia 2011 - Czech Mycology, 68(1): 1–40

In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchyMts., Oblík in the Slanské vrchyMts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was … EndNote Read more...
