Outlier SNP markers reveal fine‐scale genetic structuring across European hake populations (Merluccius merluccius)
Outlier loci separated North Sea and Northern Portugal populations from all other Atlantic samples and revealed a strong differentiation among Western, Central and Eastern Mediterranean geographical samples, supporting the hypothesis that populations might be adapted to local conditions.
Quaternary geographical sibling speciation and population structuring in the Eastern Atlantic skates (suborder Rajoidea) Raja clavata and R. straeleni
The hypothesis that restricted gene flow and genetic divergence between these taxa might be associated with climatic/oceanographic discontinuities is tested by surveying genetic variation in ten geographical samples at control region (CR) and amplified fragment length polymorphism (AFLP) loci.

The results suggest that a preference for some spawning habitat conditions could contribute to shape ABFT genetic structuring in the Mediterranean, however, further studies should be performed to assess to what extent ABFT spawning behaviour inThe Mediterranean Sea can be affected by environmental variation.
Improving the Conservation of Mediterranean Chondrichthyans: The ELASMOMED DNA Barcode Reference Library
Morphological misidentifications were found across most orders, further confirming the need for a comprehensive DNA barcoding library as a valuable tool for the reliable identification of specimens in support of taxonomist who are reviewing current identification keys.
Genetic differentiation and phylogeography of Mediterranean-North Eastern Atlantic blue shark (Prionace glauca, L. 1758) using mitochondrial DNA: panmixia or complex stock structure?
The weak, but significant, differences in Mediterranean and adjacent North-eastern Atlantic blue sharks revealed a complex phylogeographic structure, which appears to reject the assumption of panmixia across the study area, but also supports a certain degree of population connectivity across the Strait of Gibraltar, despite the lack of evidence of migratory movements observed by tagging data.
Feeding habits of anglerfish, Lophius budegassa (Spinola, 1807) in the Adriatic Sea, north‐eastern Mediterranean
The trophic level of L. budegassa estimated in the study area reached a mean value of 4.38, confirming that the species was a carnivore with a preference for large decapodes, cephalopods and fish.
Investigation of spatiotemporal patterns in mean temperature and mean trophic level of MEDITS survey catches in the Mediterranean Sea
Mean temperature (MTC) and mean trophic level (MTL) spatiotemporal patterns of MEDITS survey catches were examined in 13 geographic statistical areas (GSAs) of the Mediterranean between 1994 and…

Chelidonichthys lucerna shows a generalist and opportunistic foraging behaviour, preying mainly epibenthic and nectobenthic organisms, with fish dominating the stomach contents of larger specimens.
FEEDING HABITS OF EUROPEAN HAKE, MERLUCCIUS MERLUCCIUS(ACTINOPTERYGII: GADIFORMES: MERLUCCIIDAE), FROM THE NORTHEASTERN MEDITERRANEAN SEA
European hake, Merluccius merluccius (Linnaeus, 1758), is an important predator of deep Mediterranean upper shelf slope communities, being a nektobenthic species inhabiting a wide depth range…
Evolutionary constraints limiting the variation of Expressed Sequence Tag-linked microsatellite loci, prevent the detection of local adaptation in Mediterranean Bluefin tuna
The results suggest that the low level of polymorphism detected in this study could be ascribed to the presence of relatively conserved regions flanking these microsatellites, which are probably not involved in physiological responses to local adaptation.
