Yellowfin tuna, Thunnus albacares, is one of the most important seafood commodities in world. Despite its great biological and economic importance, conflicting evidence arises from classical genetic tagging studies concerning yellowfin tuna population structure at local global oceanic scales. Access to more powerful cost effective tools would represent first step towards resolving across distribution range. Using a panel 939 neutral Single Nucleotide Polymorphisms (SNPs), comprehensive data...
Global warming is affecting the population dynamics and trophic interactions across a wide range of ecosystems habitats. Translating these real-time effects into their long-term consequences remains challenge. The rapid extreme period that occurred after Last Glacial Maximum (LGM) during Pleistocene-Holocene transition (7-12 thousand years ago) provides an opportunity to gain insights responses natural populations periods with global warming. this post-LGM have been assessed in many...
Abstract The Antarctic silverfish Pleuragramma antarcticum (Nototheniidae) is the most abundant pelagic fish inhabiting waters. In this study we investigated, through partial sequencing of D‐loop mitochondrial region, samples collected at four different locations in Southern Ocean, three Atlantic and one Pacific sector. Sampling was replicated two years locations. Sequence analysis showed a remarkably high polymorphism, with 110 haplotypes over 256 investigated specimens, about 80% occurring...
The vertebrate mitochondrial genomes generally present a typical gene order. Exceptions are uncommon and important to study the genetic mechanisms of order rearrangements their consequences on phylogenetic output function. Antarctic notothenioid fish carry some peculiar In this first systematic 28 species, we analyzed known undescribed genome for total eight different orders within fish. Our reconstructions suggest that transpositions, duplications, inversion multiple genes most likely...
Evolution in the chronic cold of Southern Ocean has had a profound influence on physiology cryonotothenioid fishes. However, suite genetic changes underlying physiological gains and losses these fishes is still poorly surveyed. By identifying genomic signatures selection, this study aims to identify functional classes genes that have been changed following two major transitions: onset freezing temperatures loss hemoproteins. Looking at followed temperatures, positive selective pressure was...
Genetic drift and non-random mating seldom influence species with large breeding populations high dispersal potential, characterized by unstructured gene pool panmixia at a scale lower than the minimum range of individuals. In present study, set nine microsatellite markers was developed used to investigate spatio-temporal genetic patterns holoplanktonic jellyfish Pelagia noctiluca (Scyphozoa) in Southern Tyrrhenian Sea. Homozygote excess detected eight loci, individuals exhibited...
Abstract Connectivity between populations influences both their dynamics and the genetic structuring of species. In this study, we explored connectivity patterns a marine species with long‐distance dispersal, edible common sea urchin Paracentrotus lividus , focusing mainly on Adriatic–Ionian basins (Central Mediterranean). We applied multidisciplinary approach integrating population genomics, based 1,122 single nucleotide polymorphisms ( SNP s) obtained from 2b‐ RAD in 275 samples,...
Abstract Antarctic fish belonging to Notothenioidei represent an extraordinary example of radiation in the cold. In addition absence hemoglobin, icefish show a number other striking peculiarities including large-diameter blood vessels, high vascular densities, mitochondria-rich muscle cells, and unusual mitochondrial architecture. order investigate bases adaptation extreme Southern Ocean conditions we sequenced complete genome Chionodraco myersi . Comparative analyses with those teleost...

Fish of the suborder Notothenioidei have successfully radiated into Southern Ocean and today comprise dominant fish sub-order in Antarctic waters terms biomass species abundance. During evolution cold stable climate, lineage notothenioids developed several unique physiological adaptations, which make them extremely vulnerable to rapid warming currently observed. Only recently, a further phenomenon exclusive notothenioid was reported: translocation mitochondrial gene encoding NADH...

Single population common natal origin for Adriatic Scomber scombrus stocks: evidence from an integrated approach – ICES Journal of Marine Science, 70: 387–398. In order to implement proper fishery management strategies aimed at avoiding stock declines, information about connectivity among stocks populations is critically required. this perspective, the...
Abstract Mass mortalities due to disease outbreaks have recently affected a number of major taxa in marine ecosystems. Climate‐ and pollution‐induced stress may compromise host immune defenses, increasing the risk opportunistic diseases. Despite growing evidence that mass mortality events affecting species worldwide are strongly influenced by interplay numerous environmental factors, reductionist approaches most frequently used investigate these factors hindered interpretation multifactorial...
Anthropogenic noise may significantly affect marine mammals' vocalizations.

Elevated ambient mainly...
Abstract Aim A lack of genetic structure is predicted for Antarctic fish due to the duration pelagic larval stages and strength currents in Southern Ocean, particularly Circumpolar Current. In this study we explored population ocellated icefish, Chionodraco rastrospinosus , by means analysing a total 394 individuals collected at four geographical areas off Peninsula period 1996–2006.
