Contribution to the Knowledge of Macro-algae of the Coastal Area of the Island of Hvar

Hvar, an island in the Adriatic Sea, is the longest and the sunniest Croatian island, famous for its pleasant Mediterranean climate. There is great biodiversity of algal flora in the coastal area of the island because of the high range of different conditions, considering the environment and external influences. The island of Hvar is interesting to study because of the presence of the two invasive green macro-algae in the Mediterranean – Caulerpa taxifolia and Caulerpa racemosa – which has a major impact on the entire marine ecosystem. Algae play an important role in a marine ecosystem because they are indicators of pollution and they can show us the general state of an ecosystem. Due to the extreme beauty and biodiversity of the island, in 2011 Biology students association – “BIUS” conducted a biodiversity research project. The Algal section made a significant contribution to the data on biodiversity of costal macro-algae of the island considering the default parameters. The methodology was reduced to listing macro-algae from a given surface and a certain depth considering the substrate and the external influences. Anthropogenic impact and touch of fresh underground water have an important impact on the algological composition in a certain area. Listing the species was carried out in a transect of 10 meters at the same depth within 1 square meter. The research was conducted on 11 different locations on the island. The locations were selected on the basis of the greater diversity of ecological conditions. By listing the species, we were able to follow the percentage of the general appearance of algae species groups in a particular area. Since the project took place in two terms the results were analyzed considering the two growing seasons, mid-spring and early autumn. The obtained results showed us that the algological flora of the island Hvar is rather varied and that there are differences in the algal composition, considering the environment conditions. The data on the distribution of species in the coastal part of the island has showed us that there is great biodiversity of the algal flora and that it highly depends on anthropogenic impact.
