A phylogeographic analysis of mitochondrial DNA variation was performed in order to test the hypothesis of a postglacial recolonization of mid- and north-European rivers from a Danubian refuge. Over 345 chub specimens from European rivers covering most of the species' native range were investigated using 600 bp of the cytochrome b gene. Chub in European(More)
The phylogenetic relationships of cyprinid species from the Middle East and neighboring biogeographical areas were investigated using cytochrome b sequence variation in order to test hypotheses that consider the Middle Eastern area as an important interchange area or a center of speciation for the freshwater fauna. A total of 62 cyprinid species were(More)
The family Mugilidae comprises mainly coastal marine species that are widely distributed in all tropical, subtropical and temperate seas. Mugilid species are generally considered to be ecologically important and they are a major food resource for human populations in certain parts of the world. The taxonomy and systematics of the Mugilidae are still much(More)
Morphometric, allozymic, and mitochondrial DNA variability previously indicated that the Mediterranean anchovy Engraulis encrasicolus includes two distinct forms, one of the inshore habitat, and the other one of the open-sea habitat. Here, we showed that the two forms significantly differ by several morphological characters. To test the hypothesis, proposed(More)
The Chondrostoma genus is widespread in Europe, with numerous endemic species in northern Mediterranean rivers. We reconstructed the phylogenetic relationships of this genus, using the whole cytochrome b sequence and compared the two freshwater fish dispersion hypotheses: (1) dispersion around the Mediterranean Sea during the Lago Mare phase of the(More)
The phylogenetic relationships of 492 chub (Leuciscus cephalus) belonging to 89 populations across the species' range were assessed using 600 base pairs of cytochrome b. Furthermore, nine species belonging to the L. cephalus complex were also analysed (over the whole cytochrome b) in order to test potential allopatric hybridization with L. cephalus sensu(More)
The black-chinned tilapia Sarotherodon melanotheron heudelotii is an ecologically appealing model as it shows exceptional adaptive capacities, especially with regard to salinity. In spite of this, this species is devoid of genomic resources, which impedes the understanding of such remarkable features. De novo assembly of transcript sequences produced by(More)
The fish genus Siganus (Siganidae) is widely distributed in the coastal habitats of all the tropical Indo-Pacific, with 28 nominal species recognized so far, based on general morphology and coloration patterns. A mitochondrial phylogeny of 16 Siganidae species, based on the partial nucleotide sequences of the cytochome b gene, was produced. Individual(More)
We assayed the mtDNA phylogeography [196 base pairs (bp) of the cytochrome b] and population structure (n = 680) in the estuarine fish, Ethmalosa fimbriata, from its whole distribution range: 14 locations along the West African coasts were sampled. Specifically, we considered Pleistocene glaciations as well as the hydrodynamics and climatic conditions of(More)
Sarotherodon melanotheron is one of the most euryhaline teleosts able to withstand variations in environmental salinity ranging from freshwater (FW) to 130‰ hyper-saline waters (HSW). Although significant progress has been made in exploring the cellular and molecular changes that accompany salinity adaptation in teleosts, little is known about the effects(More)
