Pilegaard K. (1978): Airborne metals and SO2 monitored by epiphytic lichens in an industrial area, Environmental Pollution, 17: 81-92

The epiphytic lichen Lecanora conizaeoides was used as a monitor organism of airborne metals around an industrial area (a steelworks and an iron foundry) at Frederiksvaerk, Denmark. Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, V and Zn were determined by atomic absorption spectrophotometry and K and Na by flame emission techniques. SO 2 air pollution levels were estimated by the distribution of lichen species with different SO 2 sensitivities. A similar regional variation was found within the Frederiksvaerk … Read more...

Ellis C.J. & Yahr R. (2011): An interdisciplinary review of climate change trends and uncertainties: Lichen biodiversity, arctic–alpine ecosystems and habitat loss. – In Hodkinson T.R., Jones M.B., Waldren S. & Parnell J.A.N. (ed.) , Cambridge University Press, 457-489

We provide an overview of trends and uncertainties emerging from the growing fi eld of climate change and biodiversity research using lichens as a study group. Problems in understanding the implications of global change for lichens are relevant to other groups comprising subdominant species such as algae, mosses and liverworts. Ecological study of lichens represents a diverse range of the ascomycete fungi, which have adopted a strategy in symbiosis with an inhabitant autotrophic partner. In general … Read more...

Sellers H.L., Vargas Zesati S.A., Elmendorf S.C., Locher A., Oberbauer S.F., Tweedie C.E., Witharana C. & Hollister R.D. (2023): Can plot-level photographs accurately estimate tundra vegetation cover in northern Alaska?, Remote Sensing, 15(8): 1972 [24 p.]

Plot-level photography is an attractive time-saving alternative to field measurements for vegetation monitoring. However, widespread adoption of this technique relies on efficient workflows for post-processing images and the accuracy of the resulting products. Here, we estimated relative vegetation cover using both traditional field sampling methods (point frame) and semi-automated classification of photographs (plot-level photography) across thirty 1 m2 plots near Utqiaġvik, Alaska, from 2012 to … Read more...

This review provides information on the synthesis and revision of the structures of natural dimeric (poly)hydroxynaphthazarins, metabolites of echinoderms and lichens, and on the refinement of the direction and mechanism of reactions in the synthesis of some of these compounds. Keywords: ethylidene-bis(2,6,7-trihydroxynaphthazarin); octahydroxymethyldibenzo[b,i] xanthenetetraone; mirabiquinone; cuculoquinone; islandoquinone; hybocarpone; mesocentroquinone; sea urchins; lichens; metabolites; tautomerism.

Boch S., Saiz H., Allan E., Schall P., Prati D., Schulze E.-D., Hessenmöller D., Sparrius L. & Fischer M. (2021): Direct and indirect effects of management intensity and environmental factors on the functional diversity of lichens in Central European forests, Microorganisms, 9: 463 [18 p.]

Using 642 forest plots from three regions in Germany, we analyzed the direct and indirect effects of forest management intensity and of environmental variables on lichen functional diversity (FDis). Environmental stand variables were affected by management intensity and acted as an environmental filter: summing direct and indirect effects resulted in a negative total effect of conifer cover on FDis, and a positive total effect of deadwood cover and standing tree biomass. Management intensity had … Read more...

Bates J.W. & Brown D.H. (1981): Epiphyte differentiation between Quercus petraea and Fraxinus excelsior trees in a maritime area of South West England, Vegetatio, 48: 61-70

A survey was undertaken in S.W. England to study epiphyte differentiation between free-standing oak (Quercuspetraea) and ash (Fraxinus excelsior) trunks. Epiphyte cover was measured on 23 trees in 87 15 × 15 cm quadrats positioned on the north, east, south and west faces of each trunk at a height of 1.52 m. Measurements of 20 environmental factors were made at each quadrat position. Analysis of the vegetation data by reciprocal averaging showed that floristic variation is continuous and corresponds … Read more...
