Epiphytic flora on leaves of Posidonia oceanica (L.) DELILE from the area of Dubrovnik (south Adriatic)
Abstract
Samples were collected at 7 transects from 5 to 35 m depths in the area of Dubrovnik at different time intervals from 1977 to 1983. A total of 123 taxa (Cyanophyta and Diatomeae were not studied) were determined. Rhodophyta group are predominant with 87 taxa (70.7%) followed by Phaeophyta with 22 (17.9%) and Chlorophyta with 14 taxa (11.4%). The lergest number of epiphytic algae (86) was found at 15 m depth. At all depth Rhodophyta were dominant and mainly followed by the taxons of Phaeophyta and Chlorophyta. The taxa that occur cotinuously at all depths were established, as well as very fraquent taxa but not found at all depths, very rare taxa and taxa with discontinuous distribution. Preliminary seasonal distribution showed the taxa present in epiphytic flora all year round and taxa present in single or more seasons.
