Abstract

Marine environment is a specific habitat where all substrates are very quickly subjected to colonisation process of living organisms. In this study, that took place at the location Puntamika near Zadar, 11 different artificial substrates were exposed to marine environment for a month (March 7th - April 6th 2012) and consequently periphytic diatoms analysed. The abundance of periphytic diatoms was determined on each of the substrate and on the two shoots of marine seagrass Posidonia oceanica L. Results showed significant differences in the abundance of diatoms between substrates. Such distinction is the consequence of different physical and chemical characteristics of the substrates. Taxonomic analysis of diatom communities revealed 41 diatom genera, and Amphora, Cylindrotheca, Nitzschia, Cocconeis and Navicula were recognized as dominant in peryphitic communities.
