Lichens are used in traditional medicine, food and various other ethnic uses by cultures across the Himalayas southwestern parts of China. Evidence-based knowledge from historical modern literatures investigation 1990 proved that lichen species as medicine China totaled to 142 species; furthermore, 42 were utilized food. Moreover, some lichens popularly for produce life. An understanding clarif...

Long fire rotation, high levels of precipitation, and acidic nature of the bedrock are factors contributing to the dominance of Sphagnum in many upland and peatland communities in southeastern Labrador. Vegetation development induced by local or regional environmental change frequently involves replacement of species assemblages of various bryophytes and lichens by species assemblages dominated...

The aim of the study was to assess trace metal air pollution in the Beskidy Mountains, the Outer Western Carpathians, Poland, with a widely used bioaccumulating organism, a lichen, Hypogymnia physodes. Lichens were collected at five stands (mountains) in parallel transect and analyzed for cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) content. Concentrations of Cd, Pb and Zn in...

S u m m a ry : Previous studies have demonstrated that lichens can accumulate high amounts of radioactivity. Because of their long life expectancy they are suitable and inexpensive biological detectors of the nuclear fallout. In this study, liehen samples were collected from diffe­ rent locations in Austria over a period of more than 15 years. Samples were taken before, immediately after and a ...

Crustose lichen communities on rocks exhibit fascinating spatial mosaics resembling political maps of nations or municipalities. Although the establishment and development of biological populations are important themes in ecology, our understanding of the formation of such patterns on the rocks is still in its infancy. Here, we present a novel model of the concurrent growth, establishment and i...

We developed and tested a set of oligonucleotide primers for the specific amplification of 16S rRNA gene segments from cyanobacteria and plastids by PCR. PCR products were recovered from all cultures of cyanobacteria and diatoms that were checked but not from other bacteria and archaea. Gene segments selectively retrieved from cyanobacteria and diatoms in unialgal but nonaxenic cultures and fro...

lichen species (hypogymnia physodes and evernia prunastri) were used for biomonitoring thepossible air pollution with heavy metals in the vicinity of copper mine in the eastern part of the republic ofmacedonia. the contents of 18 elements were analysed by icp-aes and etaas techniques. for dataprocessing basic statistical methods and multivariate exploratory (factor and cluster analysis) techniq...
