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 … URL EndNote PDF 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 … URL EndNote 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 … EndNote Read more...

Zarabska D., Guttová A., Cristofolini F., Giordani P. & Lackovičová A. (2009): Epiphytic lichens of apple orchards in Poland, Slovakia, and Italy - Acta Mycologica, 44(2): 151-163

Following the study of epiphytic lichens in 30 apple orchards from Poland, Slovakia and Italy the list of 74 taxa was prepared. The most common are the meso- to xerophytic and heliophilous species. The highest number of taxa was observed in Slovak orchards. Moreover, lichens shared with at least one other country were also noted mainly in Slovakia. Bark of apple trees seems to create favourable habitats for Bacidia rubella, which together with Strangospora pinicola were valuable founds in Polish … EndNote Read more...

Apostolova I., Sopotlieva D., Valcheva M., Ganeva A., Shivarov V., Velev N., Vassilev K.,Terziyska T. & Nekhrizov G. (2022): First survey of the vascular and cryptogam flora on Bulgaria’s ancient mounds - Plants, 11(5): 705 [15 p.]

This work represents the first study of the floristic diversity on Bulgaria’s ancient mounds. The objective of this research was to assess the importance of the mounds for the preservation of the native vascular and cryptogam flora. Our sampling design included 111 ancient mounds distributed throughout the country. We recorded a total of 1059 vascular plants, 58 bryophytes and 61 lichen taxa. Despite their small area, the mounds were shown to preserve nearly a quarter of the Bulgarian flora. The … URL EndNote Read more...
