| contents | Different impact of a severe storm on two gorgonian species. Cassetti, Olivia Azzola, Annalisa Bianchi, Carlo Nike Morri, Carla Oprandi, Alice Montefalcone, Monica Anthozoa Animals Mediterranean Sea Cyclonic Storms Environmental Monitoring Ecosystem Extreme events influence ecosystem dynamics, but their effects on coastal marine habitats are often poorly perceived compared to their terrestrial counterparts. The detailed study of changes in benthic communities related to these phenomena is becoming urgent, due to the increasing intensity and frequency of hurricanes recorded in recent decades. Slow-growing benthic sessile organisms are particularly vulnerable to mechanical impacts, especially the large long-lived species with branched morphology that structure Mediterranean coralligenous assemblages. The present study evaluates the effects of the severe storm occurred in October 2018, and classified as one of most violent that ever struck north-western Mediterranean coasts, on two gorgonian species, the scleralcyonacean Corallium rubrum (with a solid carbonate axial skeleton) and the malacalcyonacean Paramuricea clavata (with a flexible proteinaceous axis). Comparing the cover and density of the two species before and after the severe storm, C. rubrum showed a decrease of more than 50% in one surveyed site. In contrast, P. clavata population did not show a decrease, and exhibited the highest density and cover in the same site, thanks to the high hydrodynamic condition which are favourable for this species. In this study, cover evaluation proved to be more time-efficient than counting colonies, and reduced the risk of errors. The present example highlighted the importance of continuous monitoring, including the assessment of the biological and ecological traits of the species, to provide a complete picture of their populations for conservation planning. |
