TI  - Comparative Cytogenetics of Hoplerythrinus unitaeniatus (Agassiz, 1829) 
      (Characiformes, Erythrinidae) Species Complex from Different Brazilian 
      Hydrographic Basins.
PG  - 191-200
AB  - Chromosomal characteristics of Hoplerythrinus unitaeniatus populations from 5 
      Brazilian river basins, namely Arinos (Amazonas basin), Araguaia, Paraguai, Alto 
      Parana, and Sao Francisco were analyzed by conventional Giemsa staining, 
      C-banding, silver nitrate impregnation, and fluorescence in situ hybridization 
      (FISH) with 18S and 5S rDNA and telomeric sequence (TTAGGG)n probes. The diploid 
      chromosome number was 2n = 48 in representatives of the populations from Paraguai 
      and Alto Parana River basins and 2n = 52 for those from the Arinos and Araguaia 
      River basins. The Sao Francisco population had individuals with 2n = 50 and 52 
      occurring in sympatry. C-banding showed heterochromatic blocks mainly located at 
      interstitial and pericentromeric positions in most of the chromosomes. Silver 
      nitrate impregnation demonstrated simple NORs for representatives from Arinos and 
      Araguaia River populations and multiple NORs for specimens from Paraguai, Alto 
      Parana, and Sao Francisco River populations. FISH with 18S and 5S rDNA probes 
      revealed many chromosomes carrying these cistrons, with up to 21 chromosomes 
      bearing 18S rDNA sites (Alto Rio Parana basin) and up to 12 chromosomes with 5S 
      rDNA sites (Paraguai basin), besides the occurrence of colocalization in all 
      populations. FISH with telomeric sequence (TTAGGG)n detected sites in the 
      terminal portion of the chromosomes in all populations. These data reinforce the 
      idea that H. unitaeniatus is a species complex. Evolutionary and biogeographical 
      aspects of the group in the Neotropical region are discussed.
