stations S5-Nik€ e and S6-G€ erlic€ e indicate the bad water quality and poor ecological status. The largest number of macrophyte species that were not heliophytes was recorded in SP8-Hani i Elezit. We can conclude that the presence of macrophyte species in river varies from nutrient levels in water. Our results show that values of macrophyte based indices reflect the water quality in sampling stations therefore we can consider them as a reliable instrument for the assessment of the ecological status of the rivers.
This paper presents the results of the heavy metals accumulation (Cd, Cr, Pb, Cu, Zn, Mn, and Fe) in soils and plants (Typha angustifolia L., Urtica dioica L., Ranunculus sardous Crantz and Rumex Crispus L.) collected along the banks of the Sitnica River, which flows through various cities of Kosovo and is quite stressed due to the discharges of urban, industrial, and agricultural pollutants. The aim of this research was to verify the accumulation of heavy metals in water, soil and plants, since vegetables that used as food are cultivated in the vicinity of sample collection. The analyses were conducted with applied methodology in the analytic laboratory of Kosovo Agriculture Institute by using MP-AES 4200 for Cd and Cr, ASS-Scientific for Zn, Cu, Fe, Mn and Pb in plant samples, whereas 4100 MP-AES was used for determination of metals in soil. The results show variations in different metal values found in the samples of the analyzed soils and plants. The lowest values accumulation of the metals analyzed were recorded at A1 (Devetak Station) near the river source and did not contain anthropogenic influences, whereas the highest values were recorded at A3 (Kuzmin Station), which belongs to the middle flow of the Sitnica River that is polluted by wastewater (urban) discharges.
In this paper we present the results of a study on the distribution of butterfly species in the protected area Mirusha Waterfalls in Kosovo, conducted in the period from April to the end of September 2016. No studies on butterfly fauna in this area had been conducted previously. The survey was organized in 13 sites with different types of habitats, mostly dominated by grassland, natural forest and shrubs. During our study 83 species of butterflies were recorded. The highest diversity (Shannon-Wiener diversity index H) was registered at the site Dush i Sverkes which hosted 68 out of 83 recorded species. The highest number of species was Euro-Siberian (ES) followed by Euro-Oriental (EO), Euro-Meridional (EM) and Holarctic species (Hol). Our results confirm a rich diversity of butterfly fauna influenced by the climate characteristics, geology and plant composition of the studied area. Out of 83 recorded species in our survey, 7 have Near Threatened status in Europe: Carcharodus floccifera (Zeller, 1847);
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
