The species diversity of bacillariophyta in wells and other aquatic biotopes in bosnia and herzegovina

The research and determination of diatoms (Bacillariophyta) have been carried out in the area of Semberija (Bosnia and Herzegovina) in several locations, which included 35 open draw-wells in 9 villages, the Sava River, at the site Bosanska Rača, the Drenovača pond in Velino Selo, artesian wells in Velino Selo and Donji Brodac, and ephemeral puddles in the immediate proximity of the researched wells. In all the investigated habitats of those locations that are subject of this study, a total of 149 species and infraspecific taxa of Bacillariophyta have been identified, of which 89 or 59.73% were identified only in the investigated wells in Semberija. On the basis of comparative analysis results, it can be concluded that 45 or 30.20% of species and infraspecific taxa of Bacillariophyta are common for the wells and other investigated localities (The Sava River, the Drenovača pond, artesian wells, ephemeral puddles). There have been identified 61 species and infraspecific taxa of Bacillariophyta or 40.93% in the Sava River, 57 species and infraspecific taxa in the Drenovača pond, or 38.25%, 21 species in front of the artesian wells and 16 species and infraspecific taxa in the ephemeral puddles. With the purpose of the objectification of the results of researched and identified diatoms in the mentioned biotopes, the numerical analysis of qualitative data on the structure of diatoms in similar biotopes, i.e. on their coenological similarities, has been carried out.
