Comparative cytogenetics of two endangered leuciscine fish, Squalius aradensis and S. torgalensis (Teleostei, Cyprinidae), from the Iberian Peninsula
In this study, the description of the karyotypes of the endangered chubs Squalius aradensis (Coelho, Bogutskaya, Rodrigues and Collares-Pereira, 1998) and Squalius torgalensis (Coelho, Bogutskaya, Rodrigues and Collares-Pereira, 1998) is presented by means of conventional (Giemsa-staining, Chromomycin A3 (CMA3)-fluorescence, Silver-impregnation (Ag-NORs)) and molecular (fluorescence in situ hyb...
متن کاملEvolutionary and biogeographical patterns within Iberian populations of the genus Squalius inferred from molecular data.
Origins and biogeography of the chub, genus Squalius (formerly within the genus Leuciscus), in the Iberian Peninsula were inferred from comparison between patterns of geographic distribution and phylogenetic relationships among populations belonging to 14 European Squalius species. The phylogeny recovered was based on the complete sequence of the mitochondrial cytochrome b gene. Squalius specie...
متن کاملGonadogenesis in chub Squalius (Leuciscus) cephalus (L. 1758).
The chub is an opportunistic, rheophilic cyprinid species and popular gamefish distributed throughout almost all of Europe, South Caucasus and part of Anatolia. It is most abundant in small rivers and large streams. The process of anatomical and cytological differentiation was analyzed in chub gonads. Material used in the study was derived from artificial spawning of adult individuals caught in...
متن کاملKaryotype and genome size of Iberochondrostoma almacai (Teleostei, Cyprinidae) and comparison with the sister-species I.lusitanicum
This study aimed to define the karyotype of the recently described Iberian endemic Iberochondrostoma almacai, to revisit the previously documented chromosome polymorphisms of its sister species I.lusitanicum using C-, Ag-/CMA(3) and RE-banding, and to compare the two species genome sizes. A 2n = 50 karyotype (with the exception of a triploid I.lusitanicum specimen) and a corresponding haploid c...
متن کاملBovine tuberculosis and the endangered Iberian lynx.
We report the first case of bovine tuberculosis in a free-living Iberian lynx (Lynx pardina), an extremely endangered feline, from Doñana National Park in Spain. The isolate (Mycobacterium bovis) correlates by molecular characterization with other isolates from wild ungulates in the park, strongly suggesting an epidemiologic link. Mycobacterium bovis infects many animal species, with wild and f...
