Patterns in the distribution of algae in shallow waters

Abstract

This study aims to determine the patterns in the distribution of marine algae in four coastal sites in the Maltese Islands: San Luċjan, Baħar iċ-Ċagħaq, Qbajjar and Santa Marija Bay. These areas were studied in relation to the depth of the sea and orientation of the rocky beach. The data collection was achieved by means of belt transects and quadrats. Results show that the sites were almost all dominated by Jania rubens and closely followed by Laurencia papillosa. The conclusion drawn as to why Jania rubens was so dominant was that this species is epiphytic, and thus covered other types of species. Environmental factors, such as high current waves, were also taken into consideration.
