The south, of the Iberian Peninsula, is part of this hotspot and holds a great number of endemic species, most of which are currently threatened. The genus Iberochondrostoma belonging to the Cyprinidae family is currently represented by four species, all of them threatened. Of these, I. lemmingii is the only one with any type of genetic study for conservation purposes. This species occurs in the Tagus, Guadiana and Guadalquivir large Iberian drainages as well as in the smaller basins of Quarteira, Gilão, Almargem and Odiel. The mitochondrial citochrome b gene and seven microsatellite loci were used to investigate the genetic variability and differentiation of samples from Aravil (Tagus drainage), Caia and Foupana (Guadiana drainage), Almargem and Quarteira (both small Mediterranean type drainages). The obtained results revealed higher levels of genetic variation in I. lemingii than those previously described for other cyprinid species in the south region of Portugal. The Foupana population from the Guadiana basin revealed the higher levels of haplotype diversity and allelic richness and the Quarteira population, presented only one mitochondrial haplotype despite high allelic diversity for microsatellites. Despite a high degree of differentiation between all samples, the population structure for I. lemmingii revealed a strong intra-drainage differentiation as well as some inter-drainage similarities, with the samples from Caia (northern Guadiana drainage) being more similar to the samples from Aravil (Tagus drainage) than to the samples of Foupana (southern Guadiana drainage). Although the differentiation within the Guadiana drainage was expected as it had already been reported for A. hispanica, the seemingly week inter-drainage differentiation contrasts with what has been reported for other cyprinids species in the southern region of Portugal. Although all pairwise FST values were significant, the ΦST values for the comparison between Quarteira and Almargem were non significant, which might be indicative of a common origin. No evidences of bottlenecks were detected and the expansion events that were detected seem to correspond to inter-glacial periods. With the obtained results it was suggested that all populations should be considered different MUs (Management Units).Coelho, Maria ManuelaAboim, Maria AnaRepositório da Universidade de LisboaCunha, Miguel Antunes Lopes da2010-07-27T08:58:31Z20092009-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdftext/xmlhttp://hdl.handle.net/10451/1474enghttp://catalogo.ul.pt/F/?func=item-global&doc_library=ULB01&type=03&doc_number=000572647info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T15:41:01Zoai:repositorio.ul.pt:10451/1474Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:28:06.653783Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
