We tested different hypotheses related to the origin and evolution of the endemic Iberian fishes Chondrostoma arcasii and Chondrostoma macrolepidotus from northern and central regions of the Iberian Peninsula. We evaluated the monophyly of the populations within each species and sought to determine if diversification of the populations coincided in time with the formation of the Iberian drainag...

Previous molecular phylogenetic studies of the genus Chondrostoma (Cyprinidae: Leuciscinae) were unable to resolve the relationship among its major species groups. In this paper we present a phylogeny for this genus, based on five mitochondrial genes and the nuclear gene beta-actin, comprising a total of 4068 bp. Bayesian inference using all gene fragments yielded a fully resolved phylogeny, co...

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 Messinian salinity crisis (Bianco's hypothesis...

İron Sazlığı Bitlis İli’nde yer alan Türkiye’nin önemli sulak alanlarından biridir. Alanda yaşayan karaburun balığı (Chondrostoma regium Heckel, 1843) bölge halkı tarafından yoğun bir şekilde tüketilmektedir. Bu çalışmada, balıkçılar Kasım (2019) tarihinde yakalanan balıkların besin kompozisyonunun belirlenerek yöre için besinsel değerinin incelenmesini amaçlanmıştır. kapsamda; balıkçıdan temin...

آلودگی انگلی دو گونه از ماهیان بومی روخانه بهشت­آباد در فصل بهار 1393 مورد بررسی قرار گرفت. در این مطالعه تعداد 52 عدد ماهی، (26 عدد نازک chondrostoma regium و 26 عدد آفانیوس aphanius vladykovi) پس از صید، در آزمایشگاه مورد بررسی قرار گرفتند. پس از انجام زیست­سنجی، بررسی­های انگل­شناسی با استفاده میکروسکوپ و استرئومیکروسکوپ انجام گرفت. براساس نتایج بدست آمده انگل philometra sp در محوطه شکمی ماه...
