Morphometric differentiation of gudgeon species inhabiting the Carpathian Basin

“…The meaning of the abbreviations can be found in the caption of Figure 2. species (Berg, 1949;Ba˘na˘rescu, 1954Ba˘na˘rescu, , 1961Ba˘na˘rescu, , 1962Ba˘na˘rescu, , 1999Vasil'eva et al, 2004Vasil'eva et al, , 2005Kottelat and Persat, 2005;Naseka et al, 2006;Kottelat and Freyhof, 2007;Nowak et al, 2008bNowak et al, , 2009Nowak et al, , 2011. But whereas the ranges of the morphometric variables usually overlap, the application of these traits for taxa differentiation is questioned by many authors (e.g., Ba˘na˘rescu, 1961Ba˘na˘rescu, , 1962Ba˘na˘rescu, , 1999Kosˇcˇo, 1997;Mendel et al, 2008). The present study revealed varying degrees of morphometric and meristic differences in the gudgeon species inhabiting the Carpathian Basin.…”

“…And these hybrids may show transitional morphologic traits, or the descendants show both parents' traits at the same time. According to some authors the intraspecific hybridization is plausible in the case of Central European gudgeon species (Ba˘na˘rescu, 1999;Mendel et al, 2008). The presence of hybrids in the museum collections cannot be ruled out as well.…”

“…Based on genetic investigations (Freyhof and Naseka, 2005;Mendel et al, 2008), the species G. gobio extends widely from the British Isles to the Black Sea coast. However, contrary to the former suppositions, this species is not indigenous in waters of the Carpathian Basin.…”

The ichthyofauna of the Moksha River, a tributary of the Volga river basin, Russia

“…Presence of two pairs of maxillary barbels, naked thorax between pectoral fins, and by the speckled dorsal and caudal fins. This species was recently recognized as valid, formerly considered junior synonym of G. gobio (Mendel et al 2008), and inhabits rivers, ponds, and water reservoirs. In many shallow rivers, this species together Barbatula barbatula reach the upper streams.…”

Molecular Biodiversity Inventory of the Ichthyofauna of the Czech Republic

“…The correct nuclear identification is ensured by sequence comparison with the results of various studies from both domestic and foreign workplaces (e. g., He et al, 2008;Mayden et al, 2008;Mendel et al, 2008d;etc. ) and international initiatives (Cypriniformes Tree of Life; Assembling the Tree of Life; etc.)…”
