Cnidarian toxins represent a rich source of biologically active compounds. Since they may act via oxidative stress events, the aim of the present study was to verify whether crude venom, extracted from the jellyfish Pelagia noctiluca, elicits inflammation and oxidative stress processes, known to be mediated by Reactive Oxygen Species (ROS) production, in(More)
Persistent organic pollutants (POPs) are known to act as "obesogens", being fat-soluble and affecting lipid metabolism. The Atlantic bluefin tuna, Thunnus thynnus, are top pelagic predators prone to bioaccumulate and biomagnify environmental contaminants. This study aimed at evaluating POPs-induced ectopic lipid accumulation in liver of adult tuna from the(More)
A description of the bacterial communities associated with the Mediterranean pennatulids (sea pens) Pennatula phosphorea and Pteroeides spinosum from the Straits of Messina (Italy) is reported. The automated ribosomal intergenic spacer analysis showed a marked difference between coral (tissues and mucus) and non-coral (underlying sediment and surrounding(More)
UNLABELLED In aquatic environments, bivalve molluscs are used as sentinel species for environmental biomonitoring. In this study Pinna nobilis specimens, the biggest Mediterranean bivalve, were collected in the Magaluf bay (Mallorca), a touristic location and in a pristine area of the Cabrera National Park as the control location. Histological and(More)
The presence of extensive pennatulacean fields was highlighted in the southern part of the Strait of Messina, Central Mediterranean Sea, during a survey carried out by a Remotely Operated Vehicle (ROV). Pennatulaceans belonging to Pteroeides spinosum were observed from 30 to 160 m. The sea pens reached densities of ≤10 specimens m−2. Their main arrangement(More)
The two-claw shrimp, Brachycarpus biunguiculatus (Lucas 1846) is a circum-tropical palaemonid (d’Udekem d’Acoz 1999) described in specimens from Algerian Mediterranean waters, but only sporadically reported (Kirinčić 2003) from Israel, Turkey and Spain, as summarized by García Raso (1987), whilst recent records from Tunisia and Croatia have been documented(More)
The ability to observe and predict trawling-induced patterns at spatial and temporal scales that are relevant to inform realistic management strategies is a challenge which scientists have consistently faced in recent decades. Here, we use fish feeding behaviour, a biological trait easily impaired by trawling disturbance, to depict alterations in fish(More)
Among filter-feeders, pennatulids are the most complex and polymorphic members of the cnidarian class Anthozoa. They display a wide distribution throughout all the oceans, constituting a significant component of the sessile megafauna from intertidal to abyssal depths. In this study, a total of 118 bacterial isolates from enrichment cultures, carried out(More)
