The Southern Ocean around Antarctica is among the most rapidly warming regions on Earth, but has experienced episodic climate change during past 40 million years. It remains unclear how ancient periods of have shaped Antarctic biodiversity. origin antifreeze glycoproteins (AFGPs) in notothenioid fishes become a classic example evolution key innovation response to can drive adaptive radiation. By using time-calibrated molecular phylogeny notothenioids and reconstructed paleoclimate, we...
Illegal, Unreported and Unregulated fishing has had a major role in the overexploitation of global fish populations. In response, international regulations have been imposed many fisheries 'eco-certified' by consumer organizations, but methods for independent control catch certificates eco-labels are urgently needed. Here we show that, using gene-associated single nucleotide polymorphisms, individual marine can be assigned back to population origin with unprecedented high levels precision....
Millions of years co-evolution between animals and their associated microbial communities have shaped diversified the nature relationship. Studies continue to reveal new layers complexity in host–microbe interactions, fate which depends on a variety different factors, ranging from neutral processes environmental factors local dynamics. Research is increasingly integrating ecosystem-based approaches, metagenomics mathematical modelling disentangle individual contribution ecological microbiome...
Abstract Population genetic structures of the mackerel (Scomber scombrus ) and chub ( Scomber japonicus were studied in Mediterranean Sea. Fragments 272 bp S. scomber 387 5′‐end mitochondrial control region sequenced from spawning individuals collected off coasts Greece, Italy, Spain, Portugal. High levels haplotypic diversity (> 0.98) found for both species. Nucleotide was higher (0.022) than (0.017). Global F ST values also significant (0.024, P < 0.0001) as opposed to (0.003, >...
Abstract Shallow population structure is generally reported for most marine fish and explained as a consequence of high dispersal, connectivity large size. Targeted gene analyses more recently genome‐wide studies have challenged such view, suggesting that adaptive divergence might occur even when neutral markers provide genetic homogeneity across populations. Here, 381 SNP s located in transcribed regions were used to assess large‐ fine‐scale the European hake ( M erluccius merluccius ),...
The Manila clam, Ruditapes philippinarum, is one of the major aquaculture species in world and a potential sentinel organism for monitoring status marine ecosystems. However, genomic resources R. philippinarum are still extremely limited. Global analysis gene expression profiles increasingly used to evaluate biological effects various environmental stressors on aquatic animals under either artificial conditions or wild. Here, we report development transcriptomic platform global profiling...
ABSTRACT The genus Aeromonas has been described as comprising several species associated with the aquatic environment, which represents their principal reservoir. spp. are commonly isolated from diseased and healthy fish, but involvement of such bacteria in human infection gastroenteritis frequently reported. primary challenge establishing an unequivocal link between pathogenesis humans is extremely complicated taxonomy. With aim clarifying taxonomic relationships among strains phenotypes, a...
Insect mitochondrial genomes (mtDNA) are usually double helical and circular molecules containing 37 genes that encoded on both strands. The arrangement of the is not constant for all species, produces distinct gene orders (GOs) have proven to be diagnostic in defining clades at different taxonomic levels. In general, it believed taxa a very low chance sharing identically arranged GOs. However, examples identical, homoplastic local rearrangements occurring do exist. this study, we sequenced...
Water temperature greatly influences the physiology and behaviour of teleost fish as other aquatic organisms. While are able to cope with seasonal variations, thermal excursions outside their normal range might exceed ability respond leading severe diseases death.Profound differences exist in tolerance across species living same geographical areas, promoting for investigating molecular mechanisms involved susceptibility resistance low high temperatures toward a better understanding...
The Strait of Gibraltar has been proposed to be the divide between two marine biogeographical regions, Mediterranean Sea and Northeast Atlantic. Intraspecific studies have shown, for several examined species, a reduction gene flow basins. present study examines genetic variation at nuclear mitochondrial loci in five teleost species belonging family Sparidae. Four samples each were analysed spanning Atlantic Mediterranean. For all individuals 17 allozyme scored combined single strand...
Antarctic waters represent a unique marine environment delimited by an oceanographic barrier, the Polar Front Zone, and characterized constant subzero temperatures presence of sea ice. A group teleost fish, Notothenioidei, have adapted to these challenging environmental conditions, undergoing remarkable diversification. In present study total 798 base pairs, generated from partial sequencing 16S 12S mitochondrial ribosomal RNA genes, were examined in 33 notothenioid species representative...
Most fishes of the perciform suborder Notothenioidei are endemic to subzero marine waters Antarctica. A number remarkable physiological attributes allow them inhabit this extreme environment; for example, blood almost all notothenioid species contains antifreeze glycopeptides. To establish a molecular phylogenetic hypothesis these fishes, DNA sequences from two mitochondrial genes, portions 12S and 16S ribosomal genes (928 base pairs [bp]), were determined 18 species. These belong 15 genera...
Abstract The gilthead sea bream (Sparus aurata L.) is a marine fish of great importance for fisheries and aquaculture. It has also peculiar sex-determination system, being protandrous hermaphrodite. Here we report the construction first-generation genetic linkage map S. aurata, based on 204 microsatellite markers. Twenty-six groups (LG) were found. total length was 1241.9 cM. ratio between sex-specific lengths 1:1.2 (male:female). Comparison with preliminary radiation hybrid (RH) reveals...
The insect order Neuroptera encompasses more than 5,700 described species. To date, only three neuropteran mitochondrial genomes have been fully and one partly sequenced. Current knowledge on is limited, new data are strongly required.

Genomic and transcriptomic approaches have the potential for unveiling genome-wide response to environmental perturbations. The abundance of catadromous European eel (Anguilla anguilla) stock has been declining since 1980s probably due a combination anthropogenic climatic factors. In this paper, we explore dynamics between individuals from high (river Tiber, Italy) low pollution (lake Bolsena, environments, which were measured 36 PCBs, several organochlorine pesticides brominated flame...

Abstract We sequenced the mitochondrial genomes of spider crabs Maja crispata and squinado (Majidae, Brachyura). Both contain whole set 37 genes characteristic Bilaterian genomes, encoded on both α- β-strands. species exhibit same gene order, which is unique among known animal genomes. In particular, all located β-strand form a single block. This order was analysed together with other nine orders for Brachyura. Our study confirms that most widespread (BraGO) represents plesiomorphic...
Sexual dimorphism is a fascinating subject in evolutionary biology and mostly results from sex-biased expression of genes, which have been shown to evolve faster gonochoristic species. We report here genome sex-specific transcriptome sequencing
There is growing concern for the wide use ofperfluorooctanoic acid (PFOA) because of its toxic effects on environment and human health. A new compound - so called C6O4 (perfluoro ([5-methoxy-1,3-dioxolan-4-yl]oxy) acetic acid) was recently introduced as one alternative to traditional PFOA, however this done without any scientific evidence when dispersed into environment. Recently, Regional Agency Protection Environment Veneto (Italy) detected high levels in groundwater Po river, increasing...
