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 … 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 … 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, … 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. Read more...

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 … Read more...

Aceto M., Arrais A., Marsano F., Agostino A., Fenoglio G., Idone A. & Gulmini M. (2015): A diagnostic study on folium and orchil dyes with non-invasive and micro-destructive methods - Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 142: 159-168

Folium and orchil are dyes of vegetal origin. Folium is obtained from Chrozophora tinctoria (L.) A. Juss., whereas orchil is obtained from Roccella and other genera of lichens. These dyes were used in the past to impart purple hue to paintings and textiles as substitutes for the more prised Tyrian purple dye, obtained from shellfish. Despite several citations in ancient technical treatises dating back at least to the Greek-Roman age, the identification of these dyes in artworks is rare. In the case … Read more...

Abrego N., Norros V., Halme P., Somervuo P., Ali-Kovero H. & Ovaskainen O. (2018): Give me a sample of air and I will tell which species are found from your region: Molecular identification of fungi from airborne spore samples - Molecular Ecology Resources, 18: 511–524

Fungi are a megadiverse group of organisms, they play major roles in ecosystem functioning and are important for human health, food production and nature conservation. Our knowledge on fungal diversity and fungal ecology is however still very limited, in part because surveying and identifying fungi is time demanding and requires expert knowledge. We present a method that allows anyone to generate a list of fungal species likely to occur in a region of interest, with minimal effort and without requiring … Read more...
