A comparison of the genetic structure of Chimaera monstrosa populations from the Atlantic Ocean and the Mediterranean Sea was carried out using mitochondrial DNA analysis. Results indicate high and significant pairwise Φ ST values with no shared haplotypes between the two areas. Furthermore, migration rate estimates suggested absence of gene flow between the two basins. These findings, coupled with the species vertical distrib...

The phylogenetic relationships among the North Atlantic Gaidropsarus and between the three Gaidropsarinae genera Gaidropsarus , Ciliata and Enchelyopus are reviewed with the hitherto most comprehensive taxonomic sampling of this group. Phylogenetic results (maximum parsimony, maximum likelihood and Bayesian inference) based on nuclear ( rhodopsin ) and concatenated mitochondrial ( 12s , 16s and cytb ) markers clearly support t...

Coryphoblennius galerita is a small intertidal fish with a wide distribution and limited dispersal ability, occurring in the northeastern Atlantic and Mediterranean. In this study, we examined Atlantic and Mediterranean populations of C. galerita to assess levels of genetic divergence across populations and to elucidate historical and contemporary factors underlying the distribution of the genetic variability. We analyse three...

One male and four female Norway gobies Pomatoschistus norvegicus are reported from the Adriatic Sea.

Known distribution of Couch's goby, Gobius couchi Miller & El‐Tawil, 1974 formerly limited to the British Isles, appears now to be extended to the Mediterranean. A new specimen collected at the island of Ischia, near Naples, Italy, is described.
