Biological Indication of Heavy Metal Pollution in the Areas of Donje Vlase and Cerje (Southeastern Serbia) Using Epiphytic Lichens

The performance of two epiphytic lichen species (Evernia prunastri (L.) Ach. and Parmelia sulcata Taylor) as bioindicators of heavy metal pollution in natural areas around the city of Nis (southeastern Serbia) were evaluated. The concentration of 19 heavy metals in lichen samples was measured by inductively coupled plasma-optical emission spectroscopy. For the majority of the elements the concentrations found in Parmelia sulcata Taylor were higher than in Evernia prunastri (L.) Ach. In addition, interspecific differences in heavy metal accumulation between Evernia prunastri (L.) Ach. and Parmelia sulcata Taylor are observed. Parmelia sulcata Taylor showed a tendency to accumulate Fe, Mn, Ni and Ti while Evernia prunastri (L.) Ach. preferentially concentrated Cu on both locations. A clear distinction between lithogenic (Mn-Cu-Ti) and atmospheric elements (Ni-Co-Cr-Ag-Pb-Hg) was achieved by cluster analysis

Desmid flora from four peat bogs in Serbia

The main objective of this paper is to report the desmid taxa identified from four Serbian peat bogs: Pešter, Daić Lake on Mt. Golija, Crvene pode on Mt. Tara and Horgoš. Samples were collected in the period from 2007 to 2011. In total, 220 desmid taxa from 22 genera were identified. The most species-rich genera are Cosmarium (81), Staurastrum (38) and Closterium (31). Of the total number, 66 desmid taxa are new for the Serbian desmid flora.
