“…Hard substrates interspersed with coral mounds and muddy bottoms are less accessible to fishing activities and thereby can provide a natural refuge for mobile fauna, as observed in submarine canyons (Yoklavich et al 2000). In fact, the benthopelagic fauna distributed in the SML coral province is not taxonomically different from the overall regional fauna (Matarrese et al 1996, D'Onghia et al 1998, Capezzuto et al 2010. D'Onghia et al (2010) detected greater abundances and sizes in the coral area (the area in Fig.…”

Using a towed camera system, a total of 422 individuals belonging to 62 taxa (including 33 identified species) were counted in the Santa Maria di Leuca (SML) coral province (Mediterranean Sea). Our findings update the knowledge of the biodiversity of this area and of the depth records of several species. The presence of coral mounds mostly in the north-eastern sector of the SML coral province seems to influence the large scale distribution of the deep-sea benthopelagic fauna, playing the role of attraction-refuge with respect to the barren muddy bottoms where fishing occurs in northern areas. Multiple Correspondence Analysis identified 3 main taxa groups: (1) rather strictly linked to the bottom, resting or moving on the seabed, often sheltering and feeding; (2) mostly swimming in the water column and mostly observed on rugged bottoms; and (3) actively swimming or hovering near the seabed. The behavioural patterns largely related to activity and position of the fauna seem to determine their small-scale distribution. The effects of different benthic macrohabitats appear to be less important and the depth within the bathymetric range examined even less so. The behavioural patterns reflect aspects of the species life strategies, revealing common features in phylogenetically and ecologically distant species. The teleost Helicolenus dactylopterus exhibited a clear behavioural pattern of resting on the seabed in different macrohabitats. The golden shrimp Plesionika martia and the fish Pagellus bogaraveo seem to be associated with the presence of corals.

“…The Munida genus is present in the north-western Ionian Sea with 4 species, M. curvimana, M. intermedia, M. rutllanti and M. tenuimana showing different distribution, abundance and frequency of occurrence (Maiorano et al, 2010). In particular, M. intermedia was more abundant and frequently occurring than M. tenuimana while M. curvimana was recordeded only once during the study period.…”

“…In particular, M. intermedia was more abundant and frequently occurring than M. tenuimana while M. curvimana was recordeded only once during the study period. The first species was generally caught on the continental slope and the second one exhibited a wider depth range of distribution, between 142 and 1500 m in depth (Company et al, 2004;Maiorano et al, 2010). Despite the many trawl surveys carried out in the last 25 years in the north-western Ionian Sea, the finding of M. rutllanti in this geographic area only dates back to 1997 and refers to the Apulia sub-area only.…”

The spatio-temporal distribution pattern of Munida rutllanti in the north-western Ionian Sea has been studied. Data were collected during 14 experimental trawl surveys conducted from 1997 to 2010 as part of the international MEDITS project. The hauls were carried out during day-light hours between depths of 10 and 800 m in the spring season. A progressive increase in the abundance index (N/km 2 ) of M. rutllanti was observed from 2000 to 2008, then a sharp decrease was shown in the last two years. The greatest and lowest abundance indices were observed in the Apulian and central Calabrian sub-areas, respectively. The species was collected between 107 and 795 m in depth, with a significant increase and decrease over time in the maximum and minimum depth of finding, respectively. A highly significant increase over time in the mean carapace length was also observed in the whole study area. The widespread occurrence and increasing abundance of this species in the Ionian Sea could be related to the increase in temperature and the variation in hydrographic conditions which occurred in the Ionian basin during the EMT-BiOS phenomenon.

“…serpens is distributed in the Mediterranean (but is very rare in the eastern part) and the eastern Atlantic northward to the northern coast of the Iberian Peninsula, as well as Madeira; elsewhere, it is distributed southward to South Africa and in the western Pacific Ocean and southern Indian Ocean (Bauchot, 1986;Golani et al, 2006). In the Mediterranean Sea, O. serpens has been reported from Greece, western Aegean Sea (Stergiou et al, 1997); the Tuscan and Latium coasts of Italy, western Mediterranean (Biagi et al, 2002); the Adriatic Sea (Dulcic et al, 2005); the Alboran Sea, western Mediterranean (Abad et al, 2007); the Ligurian Sea, western Mediterranean (Relini et al, 2007); the Tunis Southern Lagoon, central Mediterranean (Ben Amor et al, 2009); and the northwestern Ionian Sea, central Mediterranean (Maiorano et al, 2010). Additionally, Borges et al (2003) recorded 6 specimens of O. serpens from the Algarve coast (southern Portugal), near the Gibraltar Strait (Atlantic).…”
