Aquaculture Facilities

Aquaculture facilities provide a suitable habitat for a wide group of marine species that are able to colonise and settle on artificial structures. This study aims to determine the composition of fouling communities in off-coast facilities, with special emphasis on motile epifauna and amphipods as a main group. Seventeen aquaculture sites were sampled along the Mediterranean coast, collecting samples by scraping fouling organisms directly from the ropes. Additionally, thirty publications were reviewed, in order to assess the similarity of aquaculture fouling with other fouling communities. Our results reflect that amphipods accounted for more than 80% of the epifauna associated with farms fouling communities. This characteristic epifauna was defined by seven amphipod species well-adapted to colonise and survive in these off-coast habitats. Most species common in farms have also been commonly found in harbours, marinas, and/or offshore on turtles, buoys or platforms etc., showing a great resistance to polluted areas but also to dispersal via rafting on floating objects. In this study, two exotic species were identified: Caprella scaura and Stenothoe georgiana, the latter being the first report from the Mediterranean Sea. The presence of Jassa slatteryi was also confirmed, underestimated until now in the Mediterranean.

Two new amphipod species of the family Bogidiellidae were found in the hyporheal of two small rivers on Corsica. Both new species, Bogidiella (Bogidiella) cyrnensis n. sp. and B. paolii n. sp. (provisionally placed in the subgenus Medigidiella, but a definitive classification will have to wait till males are found), encountered at altitudes of 135 m and 750 m, respectively, show more affinities with certain freshwater species of Sardinia than with marine species of the Mediterranean.

We report the information on loggerhead sea turtle (Caretta caretta) nesting events which occurred on the Spanish Mediterranean coast in 2006. Two clutches of 78 and 82 eggs were discovered in the provinces of Valencia (eastern Spain) and Barcelona (north-eastern Spain). We discuss the increasing number of reports of sea turtle nests in Spain within the context of the nesting range of this species in the Mediterranean Sea.

Dictyota cyanoloma, a distinctive brown algal species characterized by a blue-iridescent margin, was recently reported as an introduced species in the Mediterranean Sea (Steen et al., 2016) but little is known about its distribution dynamics, morphological plasticity and genetic structure. In the present integrative study, we evaluate its past and present occurrence along the Mediterranean Iberian coast, assess the species’ phenology in Palamós (Girona, Spain) and analyze the haplotype diversity by sequencing 49 individuals from nine sampling sites for different chloroplast and mitochondrial DNA regions. Although D. cyanoloma currently occurs along the Mediterranean Iberian coast (in 19 of 36 localities sampled between Algeciras and Llançà, mostly in marinas and harbour environments), we were not able to find any herbarium material of this species (at BCN-Phyc and MA) predating the year 1987. In Palamós, D. cyanoloma is present all through the year, with a maximum development in winter and a minimum in summer. Fertile specimens are absent during summer (July and August). Sporophytes are dominant from January to June and dioecious gametophytes were found only in February, March and June. Information about the antheridia, which has never been described before, is provided. Two chloroplast and three mitochondrial haplotypes were observed, indicating that multiple introductions of D. cyanoloma occurred in the study area. Additionally, the genetic structure suggests that spread did not occur through simple advancing wave fronts but by several long-distance dispersal events. Further studies employing microsatellite markers could potentially offer a better resolution to unravel expansion and colonisation dynamics of D. cyanoloma in the Mediterranean Sea.

Abstract A search from different kinds of sources has been carried out to review the incidence of Physalia physalis, the Portuguese man-of-war, in the Mediterranean Sea; scientific and grey literature, social media, zoological museums were accessed. The records of the species were considered validated if documented with images or collected specimens. It was possible to date the putative first record of Physalia physalis in the Mediterranean Sea, thanks to a couple of colonies preserved in a historical collection, originating from the Gulf of Naples in 1914. Some massive strandings occurred in localities of the Alboran Sea, area of entrance from the Atlantic from where the species spread mainly along the Sicilian waters, in the central Mediterranean Sea. The records from the Italian maritime regions were then subdivided into three categories of risk according to the season of occurrence. These categories were created to assign a level of danger for swimmers to the sightings of Physalia physalis. The increasing sightings of such a poisonous organism in coastal waters can represent a risk to human health, and also to all those activities linked to the marine tourism sector. The involvement of citizens and touristic structures for the early detection of Physalia physalis can play a key role in preventing encounters with the species, allowing marine tourist facilities to operate within a range of reasonable security.

Abstract. The B / Ca ratio in calcareous marine species is informative of past seawater CO32− concentrations, but scarce data exist on B / Ca in coralline algae (CA). Recent studies suggest influences of temperature and growth rates on B / Ca, the effect of which could be critical for the reconstructions of surface ocean pH and atmospheric pCO2. In this paper, we present the first LA-ICP-MS analyses of Mg, Sr, Li and B in the CA Lithothamnion corallioides collected from different geographic settings and depths across the Mediterranean Sea and in the Atlantic Ocean. We produced the first data on temperature proxies (Mg, Li and Sr / Ca) and B / Ca in a CA species grown in different Basins (the Mediterranean Sea and the Atlantic Ocean), from shallow to deep waters (12 m, 40 m, 45 m and 66 m depth). We tested the B / Ca correlation with temperature proxies and growth rates, in order to evaluate their possible effect on B incorporation. Our results showed a growth rate influence on B / Ca, especially in the deepest sample (Pontian Isl., Italy; 66 m) and in the shallowest sample (Morlaix, Atlantic coast of France; 12 m), where the growth rates were respectively 0.11 mm/yr and 0.13 mm/yr and the B / Ca was respectively 462.8 ± 49.2 μmol/mol and 726.9 ± 102.8 μmol/mol. A positive correlation between B / Ca and the temperature proxies was found only in Morlaix, where the seasonal temperature variation (ΔT) was the highest (8.90 °C). These pieces of evidence suggest that growth rates, triggered by the different ΔT and light availability across depth, affect the B incorporation in L. corallioides.

The Impact

&lt;p&gt;Shipping has major contribution to emissions of air pollutants like NOx and SO2 and the global maritime transport volumes are projected to increase significantly. The Mediterranean Sea is a region with dense ship traffic. Air quality observations in many cities along the Mediterranean coast indicate high levels of NO2 and particulate matter with significant contributions from ship emissions.&lt;br&gt;To quantify the current impact of shipping on air pollution, models for ship emissions and atmospheric transport can be applied, but model predictions may differ from observational data. To determine how well regional scale chemistry transport models simulate pollutant concentrations, the model outputs from several regional scale models were compared against each other and to measured data.&lt;br&gt;In the framework of the EU H2020 project SCIPPER, ship emission model STEAM and the regional scale models CMAQ and CHIMERE model were applied on a modelling domain covering the Mediterranean Sea. Modeling results were compared to air quality observations at coastal locations. The impact of shipping in the Mediterranean Sea was extracted from the model excluding shipping emissions.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;

Abstract The aim of this study is to synthesize available information on sea pens in the Mediterranean Sea and fill existing knowledge gaps through modelling of suitable habitat, with the overarching goal of informing strategies for protecting sea pen habitats from trawling impacts and facilitating their recovery. A review spanning the last 30 years was conducted to map the distribution of Mediterranean sea pen species. In the Adriatic Sea, presence–absence data were modelled with generalized additive models (GAMs) to identify potentially suitable habitats for Funiculina quadrangularis, Virgularia mirabilis, and Pennatula spp. Results show that sea pen distribution in the Mediterranean is mainly limited to continental northern shelves. Six species have been recorded throughout the Adriatic basin, where habitat suitability models confirm that its soft bottoms yield favourable conditions for sea pen assemblages. This information can help guide strategies for diminishing and reversing the impacts of bottom trawling on these vulnerable habitats.
