The shamefaced crab Calappa tuerkayana Pastore, 1995 and the mantis shrimp Parasquilla ferussaci (Roux, 1828) are two crustacean species rarely reported in the Mediterranean Sea. In December 2018, two specimens of C. tuerkayana and one specimen of P. ferussaci were collected on a soft bottom at about 132 and 145 m depth during a trawl survey off Mazara del Vallo harbour (Strait of Sicily). This note reports the northernmost record of C. tuerkayana in the Strait of Sicily and confirms the occurrence of P. ferussaci in the same area. An update of the spatial distribution of these crustacean species in the Mediterranean Sea is also presented.

The occurrence of Pachygrapsus maurus and Pachygrapsus transversus is reported from the Maltese Islands for the first time on the basis of one specimen of P. maurus collected in 1990 and numerous recent specimens, and the distribution of the two species is mapped. The controversial presence of P. maurus in Italy is confirmed and two new sites for this species are reported, including the first for the mainland of Italy. The examination of the historical specimen of P. maurus from the Genova area revealed a misidentification of P. transversus; this record could be a result of ship-mediated transport. First notes on the habitat of P. maurus in the central Mediterranean Sea are given. Updated maps of the distribution of P. maurus and P. transversus in the Mediterranean are provided and the zoogeography of these species is revisited.

Density Index

The spatial representation of decapod crustaceans (Crustacea, Malacostraca) of the Strait of Sicily (Central Mediterranean Sea) is presented for the first time, together with comments on their vertical and horizontal distributions. The most relevant trawlable species were analysed using quantitative data gathered in 260 daylight lasting hauls, which covered a large portion (about 100 000 km2) of the investigated area. The index of local abundance, standardized to 1 km2, both in weight (Biomass Index), number (Density Index) and mean body weight were obtained for each species and for all species combined. A spatial representation of the Density Index was produced for all decapod crustaceans combined and for the most frequent species. In particular, the indices were transferred under a GIS system and spatial maps produced by applying the program ArcView™ 9.0. Different interpolators were tested and the most exact interpolator (IDW Inverse Distance Weighting) was chosen. Both historical (i.e., doubts about the presence or identification of the species) and spatial (i.e., differential distribution among different fishing areas) heterogeneity were detected and commented upon. Concerning the trawlable bottoms, very few species (such as Parapenaeus longirostris (Lucas, 1846), Aristaeomorpha foliacea (Risso, 1827), Aristeus antennatus (Risso, 1816), Nephrops norvegicus (Linnaeus, 1758) and Plesionika martia (A. Milne-Edwards, 1883)) are consistently and largely represented in the catches. A high spatial heterogeneity, likely reflecting the complex interaction between fishing pattern, hydrological features and bottom typology, was made evident.

Two specimens of the uncommon calappid crab Calappa tuerkayana Pastore, 1995 are reported from the central Mediterranean. One juvenile individual was caught in a trawl net at about 105 m depth on a detritus bottom, and one adult male was caught in a trammel net at 50 m depth in a similar habitat. Details about carapace ornamentation and fresh color of the adult, which complement previous descriptions are provided. Family Calappidae includes four species in the Mediterranean Sea. C. tuerkayana has been recorded a few times from its known geographic range. These are the southernmost records to date.

Abstract. Measurements of aerosol composition and size distributions were taken during the summer of 2013 at the remote island of Lampedusa in the southern central Mediterranean Sea. These measurements were part of the ChArMEx/ADRIMED (Chemistry and Aerosol Mediterranean Experiment/Aerosol Direct Radiative Forcing on the Mediterranean Climate) framework and took place during Special Observation Period 1a (SOP-1a) from 11 June to 5 July 2013. From compact time-of-flight aerosol mass spectrometer (cToF-AMS) measurements in the size range below 1 µm in aerodynamic diameter (PM1), particles were predominately comprised of ammonium and sulfate. On average, ammonium sulfate contributed 63 % to the non-refractory PM1 mass, followed by organics (33 %). The organic aerosol was generally very highly oxidized (f44 values were typically between 0.25 and 0.26). The contribution of ammonium sulfate was generally higher than organic aerosol in comparison to measurements taken in the western Mediterranean but is consistent with studies undertaken in the eastern basin. Source apportionment of organics using a statistical (positive matrix factorization) model revealed four factors: a hydrocarbon-like organic aerosol (HOA), a methanesulfonic-acid-related oxygenated organic aerosol (MSA-OOA), a more oxidized oxygenated organic aerosol (MO-OOA) and a less oxidized oxygenated organic aerosol (LO-OOA). The MO-OOA was the dominant factor for most of the campaign (53 % of the PM1 OA mass). It was well correlated with SO42-, highly oxidized and generally more dominant during easterly air masses originating from the eastern Mediterranean and central Europe. The LO-OOA factor had a very similar composition to the MO-OOA factor but was more prevalent during westerly winds, with air masses originating from the Atlantic Ocean, the western Mediterranean and at high altitudes over France and Spain from mistral winds. The MSA-OOA factor contributed an average 12 % to the PM1 OA and was more dominant during the mistral winds. The HOA, representing observed primary organic aerosol, only contributed 8 % of the average PM1 OA during the campaign. Even though Lampedusa is one of the most remote sites in the Mediterranean, PM1 concentrations (10 ± 5 µg m−3) were comparable to those observed in coastal cities and sites closer to continental Europe. Cleaner conditions corresponded to higher wind speeds. Nucleation and growth of new aerosol particles was observed during periods of north-westerly winds. From a climatology analysis from 1999 to 2012, these periods were much more prevalent during the measurement campaign than during the preceding 13 years. These results support previous findings that highlight the importance of different large-scale synoptic conditions in determining the regional and local aerosol composition and oxidation and also suggest that a non-polluted surface atmosphere over the Mediterranean is rare.

The MARCOS cruise, which took place in the South Central Mediterranean Sea on board the RV ‘Urania’, resulted in the collection of 27 species of Echinodermata from shallow to bathyal depths, many from around Malta (the Fisheries Management Zone). The fauna is represented by common to rare taxa already reported from the Mediterranean with the exception of the amphi-Atlantic ophiuroid Ophiotreta valenciennesi rufescens (Koehler, 1896), recorded from the Mediterranean Basin for the first time. Odontaster mediterraneus (von Marenzeller, 1893) and Luidia sarsi Lutken, 1858 are also first records for the Maltese Islands.

Abstract Garofalo, G., Ceriola, L., Gristina, M., Fiorentino, F., and Pace, R. 2010. Nurseries, spawning grounds and recruitment of Octopus vulgaris in the Strait of Sicily, central Mediterranean Sea. – ICES Journal of Marine Science, 67: 1363–1371. The presence of nursery and spawning grounds and the relationship between sea surface temperature (SST) and the abundance of juvenile O. vulgaris in the Strait of Sicily, central Mediterranean, are investigated using fishery-independent data (trawl surveys, 1994–2008). Annual distributions were generated for mature animals and juveniles for spring/summer (the peak spawning season) and autumn (peak recruitment) using an inverse distance weighted deterministic interpolation. Based on the persistence of abundant recruits and mature animals, respectively, nursery and spawning grounds were identified. The correlation between annual recruitment and SST during hatching and recruitment was also investigated. Concentrations of juveniles (nurseries) were located off the southwest coast of Sicily and in the central Strait of Sicily, including south of Lampedusa on the African shelf, but just one consistent concentration of mature animals (spawning grounds) was found in the northwestern part of the Strait. There was a significant positive correlation between recruitment and SST. Results are discussed in the light of environmental parameters, and a hypothesis on possible stock units in the area was developed. The direct and indirect effects of SST variation on the recruitment process were also examined.
