A catastrophic mass‐mortality episode of gorgonians and other organisms in the Ligurian Sea (North‐western Mediterranean), summer 1999
In the late summer of 1999, an extensive mortality of gorgonians and other epi-benthic organisms was observed in the Ligurian Sea (Mediterranean Sea) from the Tuscan Archipelago to Marseille.…

Investigation of within-AFC patterns indicates that the continent is a highly homogeneous area, establishing closer relationships with the Scotia Arc and to a lesser extent with the Magellan region, which may lead to a common Gondwanian origin for Antarctic and circumantarctic sponge faunas, followed by differentiation due to Gondwana fragmentation.

The colonization of epilithic diatoms on artificial hard substrates (marble, quartzite and slate) was investigated on a seasonal basis in a subtidal site of the northern Adriatic Sea to determine if…
Characteristics of a black coral meadow in the twilight zone of the central Mediterranean Sea
The hard substrata of the Mediterranean twilight zone commonly host the large, white, branched Antipathella subpinnata (Antipatharia, Myriopathidae). We discovered one of the largest populations of…
Characteristics of the Mesophotic Megabenthic Assemblages of the Vercelli Seamount (North Tyrrhenian Sea)
This study highlights the potential role of an isolated rocky peak penetrating the euphotic zone of a Tyrrhenian seamount to work as an aggregating structure, hosting abundant benthic communities dominated by suspension feeders, whose distribution may vary in accordance to the geomorphology of the area and the different local hydrodynamic conditions.
Gorgonian population recovery after a mass mortality event
The average size of the colonies decreased, indicating a size-dependent mortality episode, but their density, as a result of successful recruitment, was not altered after 3 yr, and P. clavata showed three recovery patterns: sexual reproduction, coenenchyme regeneration and fragmentation of affected branches.
Fishing impact on deep Mediterranean rocky habitats as revealed by ROV investigation
Deep Coral Oases in the South Tyrrhenian Sea
The recorded coral β-diversity among the shoals supports the hypothesis that these habitats behave like small oases of hard substrata interspersed in a muddy bottom, and stresses the need of specific actions aimed at the urgent protection of these oasis of biodiversity.
