STRUCTURE AND FLORISTIC DIVERSITY OF THE COMMUNITY CALAMAGROSTIETUM EPIGEJI JURASZEK 1928 WITHIN DIFFERENT BIOTOPES
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2016, Vol 37, Issue 325
Abstract
The aim of the present paper was to determine the structure and floristic diversity of Calamagrostietum epigeji occurring within different biotopes (sand and gravel post-excavation pits, “Gilów” post-flotation waste dump, and an urban area in Szczecin). Based on previous publications, a synthetic table was compiled to present the phytosociological constancy (S) and cover coefficient (D) of species occurring in the analysed phytocoenoses. Analysis of the similarity between the communities was performed with the UPGMA method and Euclidean distances on the basis of species phytosociological constancy using the Statistica PL package. Similarity coefficients were also calculated for the distinguished phytocoenoses with the Sörensen method and the results were presented in Czekanowski’s diagram. As revealed by the UPGMA method, the greatest similarity was exhibited by communities developing within the “Storkowo I” and “Storkowo II” pits and in the “Mielenko Drawskie” pit. These phytocoenoses, which are undergoing the initial succession stage, are characterised by distinct dominance of Calamagrostis epigejos and a low number of species (from 38 to 49 taxa, on average from 10 to 15 per relevé). The other group comprises communities representing later stages of succession from the “Gilów” post-flotation waste dump and the long abandoned “Krzynka” and “Szczecin- -Żydowce” pits. These phytocoenoses exhibit substantially higher floristic richness (from 61 to 114 species, on average from 15 to 20 per relevé); hence, the cover coefficient of the bushgrass is considerably lower. The urban area in Szczecin is the most diverse biotope, in which, due to the more favourable soil conditions, rich phytocoenoses characterised by a mean number of 25 taxa per relevé and a low cover of Calamagrostis epigejos have developed.<br/><br/>
