RFLP analysis of four regions of mitochondrial DNA (cytochrome b, D-loop, ND-5/6) amplified by PCR was used. Ten and nine haplotypes were found in S. glanis and S. aristotelis, respectively. No haplotype was shared between the two species. Significant geographical substructuring was observed in the distribution of haplotypes, with most populations possessing private haplotypes. These haplotypes can serve as genetic 'tags' and therefore warrant protection. Haplotype diversity was very low for all Greek S. glanis populations, possibly because the small size and large annual fluctuations of Greek inland waters do not support large fish populations. Nucleotide divergence was in the range of 0.00-0.52% among S. glanis populations, and 0.00-0.11% among S. aristotelis populations. Historical factors such as glaciations could account for these low values. The value of 6.75% sequence divergence of the two species refutes the classification of the two species in different genera, as proposed by some authors. This study constitutes the first attempt, based on mitochondrial molecular data, to address the complicated evolutionary history of the two species which belong to the widely distributed and economically important Siluridae family.10agenetic variation10amtDNA10aphylogeny10aSilurus aristotelis10aSilurus glanis1 aTriantafyllidis, A.1 aAbatzopoulos, Theodoros, J.1 aEconomidis, P.S. uhttps://icgf.myspecies.info/content/genetic-differentiation-and-phylogenetic-relationships-among-greek-silurus-glanis-and01878nas a2200265 4500008004100000245018800041210006900229260001200298300001200310490000700322520094000329653002801269653001101297653002301308653001001331653001401341653001001355100001801365700002201383700001801405700001601423700001501439700002501454856013301479 1998 eng d00aGenetic differentiation and phylogenetic relationships among Greek Chub Leuciscus cephalus L. (Pisces, Cyprinidae) populations as revealed by RFLP analysis of mitochondrial DNA0 aGenetic differentiation and phylogenetic relationships among Gre c1998/// a415-4290 v263 aThe phylogenetic and systematic relationships among 12 populations of Greek chub (Leuciscus cephalus L.) were investigated using RFLP analysis of two PCR-amplified mtDNA segments (D-loop and cytochrome b). Three out of eight, and nine out of ten restriction enzymes were polymorphic for D-loop and cytochrome b; respectively. Twenty-one different haplotypes were detected. Estimated nucleotide sequence divergence among the 21 genotypes ranged from 0.313 to 6.79%; the mean value of sequence divergence among populations was 3.421 ± 0.00%. The calculated N(ST) value of 0.94, indicates high interpopulation diversity. Dendrograms based on haplotypes as well as those of population, support the previous recognition of different subspecies, but these mtDNA data are not concordant with previous allozyme data among these fish. Our results suggest that to clarify phylogenetic relationships multiple genetic systems need to be examined.10aGenetic differentiation10aGreece10aLeuciscus cephalus10amtDNA10aphylogeny10aRFLPs1 aImsiridou, A.1 aApostolidis, A.P.1 aDurand, J.-D.1 aBriolay, J.1 aBouvet, Y.1 aTriantaphyllidis, C. uhttps://icgf.myspecies.info/content/genetic-differentiation-and-phylogenetic-relationships-among-greek-chub-leuciscus-cephalus-l01349nas a2200217 4500008004100000245021900041210012300260260010600383653001400489653001200503653000900515653001400524653001100538653001700549653002900566653001700595653002300612653001500635100003500650856044600685 1994 eng d00aMΕΡΙΚΕΣ ΑΠΟΨΕΙΣ ΓΙΑ ΤΗ ΦΥΛΟΓΕΝΕΣΗ ΚΑΙ ΤΗ ΖΩΟΓΕΩΓΡΑΦΙΑ ΤΩΝ ΨΑΡΙΩΝ ΤΟΥ ΓΕΝΟΥΣ Cobitis (Pisces, Cobitidae) ΤΗΣ ΝΟΤΙΑΣ ΒΑΛΚΑΝΙΚΗΣ0 aMΕΡΙΚΕΣ ΑΠΟΨΕΙΣ ΓΙΑ ΤΗ ΦΥΛΟΓΕΝΕΣΗ ΚΑΙ ΤΗ ΖΩΟΓΕΩΓΡΑΦΙΑ ΤΩΝ ΨΑΡΙΩΝ aΒΟΛΟΣbΕΛΛΗΝΙΚΗ ΕΤΑΙΡΕΙΑ ΒΙΟΛΟΓΙΚΩΝ ΕΠΙΣΤΗΜΩΝc5-7 ΜΑΙΟΥ10aCobitidae10aCobitis10afish10aphylogeny10aPisces10azoogeography10aζωογεωγραφία10aΙχθείς10aφυλογενία10aψάρια1 aΟικονομίδης, Π.Σ. uhttps://icgf.myspecies.info/content/m%CE%B5%CF%81%CE%B9%CE%BA%CE%B5%CF%83-%CE%B1%CF%80%CE%BF%CF%88%CE%B5%CE%B9%CF%83-%CE%B3%CE%B9%CE%B1-%CF%84%CE%B7-%CF%86%CF%85%CE%BB%CE%BF%CE%B3%CE%B5%CE%BD%CE%B5%CF%83%CE%B7-%CE%BA%CE%B1%CE%B9-%CF%84%CE%B7-%CE%B6%CF%89%CE%BF%CE%B3%CE%B5%CF%89%CE%B3%CF%81%CE%B1%CF%86%CE%B9%CE%B1-%CF%84%CF%89%CE%BD-%CF%88%CE%B1%CF%81%CE%B9%CF%89%CE%BD-%CF%84%CE%BF%CF%85-%CE%B3%CE%B5%CE%BD%CE%BF%CF%85%CF%83-cobitis-pisces
