TI  - Chromosomal Diversity in Two Allopatric Populations of Farlowella hahni Meinken

AB  - Farlowella is the second richest genus in Loricariinae, broadly distributed in 
      freshwater streams and rivers of South America. In this article, we aimed to 
      expand on the cytogenetic and molecular data available for two allopatric 
      populations of Farlowella hahni. Both populations had diploid chromosome number 
      58, but with karyotype differences, indicative of chromosomal rearrangements. 
      C-banding showed large heterochromatic blocks at telomeric regions in acrocentric 
      chromosomes in both populations. Fluorescence in situ hybridization (FISH) 
      revealed a single 18S rDNA site in both populations and a single 5S rDNA site for 
      individuals from lower Parana River basin (native region) and multiple 5S rDNA 
      sites for individuals from upper Parana River basin (non-native region). 
      Mitochondrial sequence analyses did not separate the two F. hahni populations. 
      The cytogenetic and molecular data obtained are relevant in a preliminary study 
      and suggested the existence of cryptic diversity and the hypothesis that at least 
      two Farlowella lineages may coexist in the Parana basin.
