How allopolyploids are able not only to cope but profit from their condition is a question that remains elusive, but is of great importance within the context of successful allopolyploid evolution. One outstanding example of successful allopolyploidy is the endemic Iberian cyprinid Squalius alburnoides. Previously, based on the evaluation of a few genes, it was reported that the transcription l...

Polyploidy, hybridization and variation in mating systems are central issues for a deeper understanding of animal evolution. The Iberian species Squalius alburnoides represents an example combining all three phenomena. Previous studies showed that S. alburnoides populations are mainly composed of triploid and diploid hybrid forms (mainly females), and that the tetraploid forms are rare or absen...

Squalius alburnoides is a widely distributed intergeneric hybrid complex with fish of both sexes, varying ploidy levels and proportions of the parental genomes. Its dispersal routes were here delineated and framed by the reconstruction of the phylogeny and phylogeography of other Squalius with which it hybridizes, based on the available data on the paleohydrographical history of the Iberian Pen...

length-weight relationship and condition factor were estimated in seven fish species, including barbus cyri, capoeta gracilis, alburnoides eichwaldii, pseudorasbora parva, ponticola cyrius, cobitis keyvani and acanthalburnus microlepis from shahrbijar river, guilan province, iran. a total of 416 specimens ranging from 18 to 135 mm in total length and from 0.06 to 19.25 g in total weight were co...

A new microsatellite locus (SAS1) for Squalius alburnoides was obtained through cloning by serendipity. The possible usefulness of this new species-specific microsatellite in genetic studies of this hybrid-species complex, was explored. The polymorphism exhibited by SAS1 microsatellite is an important addition to the set of microsatellites previously used in genetic studies in S. alburnoides co...

khorasan-e-razavi province in the northeast of iran possesses varied climatic and geographical conditions that lead to a rich biodiversity. an investigation on the status of the fish fauna was carried out from march to october 2013. a total of 401 specimens was collected and identified, from 30 localities among seven counties in this province. sampling was performed using hand net, cast net and...
