Sažetak
Gorgonians are important structural species of the Mediterranean hard-bottom communities threatened by disturbances such as elevated seawater temperature, mucilaginous events and destructive fishing. In this study we assessed for the first time the population structure and conservation status of one of the most representative gorgonians in the Eastern Adriatic Sea, Eunicella cavolini, which has been scarcely studied to date. During May 2009 and 2011, 6 populations (N = 1250 colonies) located between 10 to 30 m depth were examined by SCUBA diving. Density ranged between 12 and 19 colonies per m2. The mean and maximum colony height was 14.3 ± 8.2 cm (± SD) and 50 cm, respectively. Smaller size classes (< 20 cm) were prevalent in all populations. The mean extent of injury (i.e. denuded axis or epibiosis) was 8.5 ± 4.4% (± SD) and varied significantly from 4 to 16.5% (Kruskal-Wallis, p < 0.001). The proportion of healthy colonies (with < 10% of injured surface) was high in almost all of studied populations (> 60%). In most populations, < 10% of colonies exhibited > 50% of injured surface. There was no significant difference in the proportion of injured colonies (> 10% of injured surface) among different size classes (Kruskal-Wallis, p = 0.059), but majority of injured colonies were > 10 cm in height. The obtained results highlight the good conservation status of E. cavolini populations, providing useful baseline data for evaluation of future impacts in this area.
