The Mediterranean Sea is characterized by large scale gradients of temperature, productivity and salinity, in addition to pronounced mesoscale differences. Such a heterogeneous system is expected to shape the population dynamics of marine species. On the other hand, prevailing environmental and climatic conditions at whole basin scale may force spatially distant populations to fluctuate in synchrony. Cephalopods are excellent case studies to test these hypotheses owing to their high sensitivity to environmental conditions. Data of two cephalopod species with contrasting life histories (benthic octopus vs nectobenthic squid), obtained from scientific surveys carried out throughout the Mediterranean during the last 20 years were analyzed. The objectives of...

The uncertainty in age estimation by otolith reading may be at the root of the large variability in red mullet (Mullus barbatus) growth models in the Mediterranean. In the MEDITS survey, red mullet age data are produced following the same sampling protocol and otolith reading methodology. However, ageing is assigned using different interpretation schemes, including variations in theoretical birthdate and number of false rings considered, in addition to differences in the experience level of readers. The present work analysed the influence of these variations and the geographical location of sampling on red mullet ageing using a multivariate approach (principal component analysis). Reader experience was the most important parameter correlated with the...

MACRO-DECHETS en Méditerranée française : Etat des connaissances, analyses des données de la surveillance et recommandations ArchiMer
Galgani, Francois.
Cette étude traite de la problématique des macrodéchets en Méditerranée française, en précisant la nature, la distribution et les effets des déchets et en identifiant les méthodes, les acteurs et le cadre juridique. En mer, les données recueillies par l 'IFREMER au cours des campagnes de pêche (campagnes MEDITS) ont été analysées. Les résultats permettent de tirer un ensemble de conclusions : - les plastiques sont clairement les déchets les plus représentés en Méditerranée française. Ils représentent parfois plus de 80% des objets récoltés dans les chaluts et sont parfois plus importants en nombre et en poids que certaines espèces commerciales de poissons. - le plateau et la pente continentale de la Corse sont plus affectés que le golfe du Lion, - le...

Spatial and temporal trend in the abundance and distribution of gurnards (Pisces: Triglidae) in the northern Mediterranean Sea ArchiMer
Colloca, Francesco; Milisenda, Giacomo; Capezzuto, Francesca; Cau, Alessandro; Garofalo, Germana; Jadaud, Angelique; Kiparissis, Sotiris; Micallef, Reno; Montanini, Stefano; Thasitis, Ioannis; Vallisneri, Maria; Voliani, Alessandro; Vrgoc, Nedo; Zupa, Walter; Ordines, Rancesc.
In this study we investigated the spatio-temporal distribution of gurnards (8 species of Triglidae and one species of Peristediidae) in the northern Mediterranean Sea using 22 years of MEDITS bottom trawl survey data (1994-2015). Gurnards showed significant differences in terms of abundance, dominance and composition among geographical sub-areas and ecoregions, with the highest relative biomass (BIy) being found in Malta, eastern Corsica, the Balearic Islands and the eastern Ionian Sea. The lowest gurnards BIy were observed in the highly exploited areas of the western Mediterranean and the Adriatic Sea, where the largest number of species with a negative linear trend in BIy was also found. The temporal trends in species abundances highlighted a general...

Spatial distribution of marine macro-litter on the seafloor in the northern Mediterranean Sea: the MEDITS initiative ArchiMer
Spedicato, Maria Teresa; Zupa, Walter; Carbonara, Pierluigi; Fiorentino, Fabio; Follesca, Maria Cristina; Galgani, Francois; Garcia-ruiz, Cristina; Jadaud, Angelique; Ioakeimidis, Christos; Lazarakis, Giorgios; Lembo, Giuseppe; Mandic, Milica; Maiorano, Porzia; Sartini, Marina; Serena, Fabrizio; Cau, Alessandro; Esteban, Antonio; Isajlovic, Igor; Micallef, Reno; Thasitis, Ioannis.
Marine litter is one of the main sources of anthropogenic pollution in the marine ecosystem, with plastic representing a global threat. This paper aims to assess the spatial distribution of plastic macro-litter on the seafloor, identifying accumulation hotspots at a northern Mediterranean scale. Density indices (items km–2) from the MEDITS trawl surveys (years 2013-2015) were modelled by generalized additive models using a Delta-type approach and several covariates: latitude, longitude, depth, seafloor slope, surface oceanographic currents and distances from main ports. To set thresholds for the identification of accumulation areas, the percentiles (85th, 90th and 95th) of the plastic spatial density distribution were computed on the raster data. In the...

Spatio-temporal trends in diversity of demersal fish assemblages in the Mediterranean ArchiMer
Farriols, M. Teresa; Ordines, Francesc; Carbonara, Pierluigi; Casciaro, Loredana; Di Lorenzo, Manfredi; Esteban, Antonio; Follesa, Cristina; García-ruiz, Cristina; Isajlovic, Igor; Jadaud, Angelique; Ligas, Alessandro; Manfredi, Chiara; Marceta, Bojan; Peristeraki, Panagiota; Vrgoc, Nedo; Massutí, Enric.
The high species richness, coupled with high proportion of endemism, makes the Mediterranean one of the world’s ‘biodiversity hotspots’. However, the continuous increase in fisheries in the last few decades has led to the overexploitation of their main commercial stocks. Using fishery-independent data collected under the framework of the MEDITS trawl surveys carried out over the last 20 years, we study the demersal fish diversity pattern in the Mediterranean at a large spatial and temporal scale to determine whether it is being affected by the general fishing overexploitation of the demersal resources. The detected diversity trends are compared with the spatio-temporal variation in bottom trawl fishing effort in the Mediterranean. Our results show a...
