... Na sua revisão do género Chondrostoma publicada em 1997, Elvira reconheceu 26 espécies como pertencendo a este género. No mesmo ano, Bogutskaya descreveu Chondrostoma beysehirense, uma nova espécie para as águas turcas (Bogutskaya, 1997). Ambos os autores basearam os seus trabalhos em critérios apenas morfológicos e osteológicos, considerando a presença de uma boca ínfera e dotada de um estojo córneo como o caracter mais importante no reconhecimento das espécies deste género. ...
... Thus, there are seven species for which molecular information is lacking. These are, however, a cohesive group in morphological terms (Bogutskaya, 1997;) that share the traits possessed by all members of the C. nasus group for which molecular data exists. In addition, all seven species are distributed in the eastern part of the range of Chondrostoma (Turkey and nearby areas). ...

Fishes formerly included in the genus Chondrostoma (Cyprinidae: Leuciscinae) are distributed through South and Central Europe, from the Atlantic to the Caspian and from the Mediterranean to the Baltic. They are also found in Asia Minor, the Caucasus and Mesopotamia. The number of species included in the group has varied according with the authors due to the use of different diagnostic criteria (i.e. morphological and osteological or molecular). Previous molecular phylogenetic studies of this group yielded unresolved polytomies although some monophyletic and statistically well supported clades were identified: toxostoma, lemmingii, polylepis, arcasii, nasus, soetta e genei. The present thesis aimed to achieve several objectives at various levels. At a macroevolutionary scale this study attempted to solve the phylogeny of the fish traditionally included in Chondrostoma with a broader sample of taxa and more DNA fragments. At the same time the study aimed to clarify the diversification of this group in the Iberian Peninsula. The main results can be summarized as follows. A statistically robust phylogeny of the fish formerly included in the genus Chondrostoma was obtained. The former polytomies were solved which indicates that they were likely due to insufficient taxon sampling or scarcity of molecular data. Mapping of morphological characters on the inferred phylogeny showed that several traits considered to be diagnostic of the genus were homoplasic. Thus a revison of the genus Chondrostoma was undertaken. This revision restricted the genus Chondrostoma to the nasus lineage and gave rise to the new genera Pseudochondrostoma, Parachondrostoma, Iberochondrostoma, Achondrostoma and Protochondrostoma (corresponding to the lineages polylepis, toxostoma, lemmingii, arcasii and genei, respectively). The cladogenetic events that gave rise to these lineages seem to have occurred 11 million years ago, excluding the hypothesis of diffusion and diversification during the oligohaline Lago Mare phase of the Mediterranean, near the end of the Messinian. Thus the model of dispersal proposed by Bianco does not hold for this group of fish. Summary XIThree of the six genera defined in this work are endemic of the Iberian Peninsula and another one has the majority of its species in the peninsula, with a little extension to France. These data and the chronology estimated for the diversification inside these genera suggest that most of the radiation in this group occurred in the Iberian Peninsula long before the end of the Miocene. It seems that in this group the contacts between the peninsula and the rest of Europe were, in recent times, very scarce, and limited to connections between northeast Spain and France. In the Iberian Peninsula the genera Achondrostoma, Iberochondrostoma and Parachondrostoma have disjunct but adjacent distribution areas which suggests that vicariant processes may have played a fundamental role in their differentiation. Pseudochondrostoma shows several resemblances with the genera Parachondrostoma and Chondrostoma (e.g. inferior mouth with a horny blade, comparably large size and pre-reproductive migrations) with the genera Parachondrostoma and Chondrostoma. The hypotheses of these resemblances being the result of convergent evolution or ancient hybridization events are discussed. The phylogenetic analysis of the genus Achondrostoma showed that this genus includes two lineages separated since the Miocene. A. arcasii is polyphyletic and includes fish from the two lineages referred above, thus a revision of its taxonomy is urgently needed. This phylogenetic information, combined with morphological data, allowed the identification of a new species in the southwest of the distribution area of the genus Achondrostoma, Achondrostoma occidentale. This new species is endemic of the Lisbon district and it is considered Critically In Danger. As the name macrolepidotum was unavailable it was necessary to rename Achondrostoma macrolepidotum to A. oligolepis. The analysis of the deep phylogeography of the genus Iberochondrostoma resulted in the proposal of a model of speciation in which a large central species, Iberochondrostoma lemmingii, originated in its periphery and at different geological times, diverse species with small distribution areas. This peripatric speciation model is supported by mitochondrial and nuclear DNA and it seems consistent with the geological history of the Iberian Peninsula in the Tertiary. The phylogeographic analysis of the populations of Iberochondrostoma lusitanicum allowed the identification of distinct ESUs, which in turn impose the description of a new species, as soon as possible, as well as revealing important information to the conservation strategies of this Critically in Danger species. Summary XIIThe studies on the reproductive behaviour of I lusitanicum, and on the agonistic behaviour of Pseudochondrostoma polylepis revealed some ethological patterns relevant to the conservation of the species. It was also the case with the study on the expansion of Alburnus alburnus in the Iberian Peninsula, a species which has spread very quickly in recent years. The development of primers that allowed the amplification of a fragment of more than 900 base pairs of the nuclear beta actin gene was fundamental to almost all genetic studies referred above. Beside its contribution to these studies, it allowed the recognition of the paternal ancestor of Squalius alburnoides an hybridogenetic species which resulted from crossings between S. pyrenaicus females and males phylogenetically very close to but distinct from Anaecypris hispanica. The fact that species of the genera Alburnus and Squalius hybridize easily and the phylogenetic proximity between Alburnus, Anaecypris and one of the lineages that integrates S. alburnoides, brings great concerns about the expansion of Alburnus alburnus. The high potential of hybridization recorded between this last species and fishes of the genus Squalius is well known and may result in the genetic descaracterization of several species endemic to the Iberian Peninsula. Finally, a new method was developed and validated, that allows the attribution of different bases present in the DNA chromatograms of diploid or polyploidy fishes to each one of the constitutive chains, taking advantage of artefacts of the sequencing process induced in the vicinity of heterozygous indels. This method is useful in the analysis of multiple SNP’s in the same fragment, in the identification of DNA sequences present in hybrids and in the distinction of several kinds of polyploids.

Chondrostoma olisiponensis sp. nov. is described from the lower Rio Tejo Basin. It is a small species (all specimens examined less than 105mm SL) distinguished from the other species of Chondrostoma s.l. by the following combination of characters. Chondrostoma olisiponensis lacks a horny blade on the lower jaw, has a pronouncedly arched mouth, and lacks an intense reddish coloration at the base of the fins. It has elongated pelvic fins that reach the anus and often pass the anal-fin insertion in males, and dorsal, pelvic and anal fins usually have 8 branched rays. The new species has 36 to 43 scales in the lateral line, 7.0 to 8.5 scales above the lateral line, 13 to 16 circumpeduncular scales, denticulated (vs. smooth) grinding teeth surfaces, 6-5/5 pharyngeal teeth and 15 to 19 gill rakers. Chondrostoma olisiponensis is further distinguished from C. lusitanicum, a phylogenetically close species that lives in the same area, by having a higher body, a relatively longer head, and a larger eye. The origins of anal and pelvic fins are displaced anteriorly, while the origin of pectoral fins is displaced posteriorly. Pelvic and pectoral fins and last anal-fin ray are longer in the new species. Unlike the other species in the genus, C. olisiponensis shows external sexual dimorphism, with males having longer pelvic fins whose extremities pass the anus and often overlap with the anal fin. This description raises concerns on the recently proposed splitting of Chondrostoma s.l. since the morphological traits deemed characteristic of some genera are unsuitable for their diagnosis. The species should be considered Critically Endangered (CR) according to IUCN criteria B1ab(ii,iii,iv)c(iv)+2ab(ii,iii,iv)c(iv).
... Twenty-six species are recognized for Chondrostoma by Elvira (1997) based on mainly osteological characters, as well as one new described species from Turkey (C. beysehirense) by Bogutskaya (1997) on pure morphological grounds. The variation of criteria among authors and the discrepancies between molecular and morphological data generated a troublesome situation concerning the delimitation of the genus Chondrostoma, which remains as yet unresolved. ...

Distribution of the genus Chondrostoma in Iran, which is mostly known from the Caspian Sea, Tigris River, Kor River and Esfahan basins was mapped. The Kura nase, Chondrostoma cyri is reported from Armenia, Georgia and Iran and it is found in the streams and rivers draining to the western coast of the Caspian Sea from the Kuma River in the north southward to the Kura and Aras River basins in the south. The king or Mesopotamian nase, C. regium is widely distributed in Turkey, Iran, Iraq and Syria. It is found in the Qweik and Orontes River basins (Mediterranean Sea basin), the endorheic Esfahan basin and exorheic Tigris-Euphrates and Zohreh River basins (Persian Gulf basin). The Kor nase, C. orientale is distributed only in the endorheic Kor River basin of Iran and prefers medium to large streams and also large rivers.

This study was carried out from January to December 2008 in order to determine the freshwater fish fauna of Gaziantep. A total of 36 fish species were determined belonging to 9 families in Gaziantep water bodies linked with Euphrates and Orontis rivers basins. As a result, it can be claim Gaziantep has a rich species diversity for the freshwater fish fauna. Reason of rich species diversity can be explain by Gaziantep freshwater affected by both Orontes and river basin.

Turkey shows a notable diversity of habitats, with significant variations in altitude, rainfall, temperature, topography and geological history, which is reflected in its richness of biodiversity. Although there are quite a number of publications on the freshwater fish taxonomy, the data set for endemic freshwater fish as assemblages are poor. According to recent findings, a total of 194 endemic freshwater fish species are now recognised within the political boundaries of Turkey. Endemic fish consist of 47.4% of the Turkish freshwater ichthyofauna (409 species). At the family level, the Cyprinidae comprises the greatest number of endemic species (110 species; 56.7% of the endemic species), followed by the Nemacheilidae (31 species; 16.0%), Cyprinodontidae (18 species; 9.3%), Cobitidae (14 species; 7.2%), Salmonidae (12 species; 6.2%), Gobiidae (7 species; 3.6%), Petromyzontidae (1 species; 0.5%) and Clupeidae (1 species; 0.5%). A total of 143 species (73.71%) are found within a single basin. Considering species diversity, the Konya endorheic basin (64.10%) is the richest in endemics, followed by Burdur (52.38%), Büyük Menderes (40.28%), Van Gölü (38.46%) and Antalya (34.00%). IUCN Red List criteria of 194 endemic species that were evaluated, 18 species (9.3%) are CR, 38 species (19.6%) EN, 17 species (8.8%) VU, 12 species (6.2%) NT, 35 species (18.0%) LC, 11 species (5.7%) DD and 59 species (30.4%) NE. In total, 4 (2.1%) of the species which are endemic to Turkey are already extinct. In this study, the endemic freshwater fish fauna is analysed in terms of their systematic, ecology and distribution pattern for inland basins of Turkey.

We present detailed cytogenetic properties of the Beyşehir nase, Chondrostoma beysehirense from Lake Beyşehir investigated through conventional Giemsa staining, C-banding and Ag-NOR in 10 specimens. The diploid number of chromosomes was 50, and the chromosomes in karyotypes were distinguished as metacentric, submetacentric/subtelocentric and acrocentric. Morphologically differentiated sex chromosomes could not be recognized. A secondary constriction was observed on the short arm of the sixth submetacentric chromosome pair. Some chromosomes had centromeric and pericentromeric C-bands, and the short arm of the sixth submetacentric chromosome pair was entirely C-positive. The active NOR was localized on the short arm of the sixth submetacentric chromosome pair, and this active NOR was associated with a large C-heterochromatin region. This NOR was recorded in all specimens examined and it occurred always in the homomorphic state on both homologous chromosomes. Systematics of Chondrostoma species will be better understood by using both molecular and FISH techniques in the future.
