Distribution of benthos at jabuka, an islet of volkanic rock (Adriatic Sea)

On the jabuka cliffs, the marine flora and fauna are very diversified. About 300 taxa have been identified so far, more than 150 being noted for the first time in the area. The foraminiferan Discoramulina bollii, and the bryozoans Apousina filum and Buffonnellaria divergens had not been previously noted in the Adriatic Sea. Five benthic communities were identified along the rocky walls from the supralittoral zone to about 60 m depth, some of them exhibiting a belt-like distribution. A noticeable feature of these assemblages is the microhabitat co-occurrence of species typical from particular depth zones and/or habitat niches. Considering the considerable biotic interest of the Jabuka islet, a protection status should be given to its terrestrial and marine parts.
