Within the 34 control area sequences determined in this research we observed an overall total of 14 haplotypes (GenBank #EU022531–EU022544). Seven among these haplotypes corresponded to those formerly reported by Cunha et al. (2005) and/or Caballero et al.
(2007) whereas one other seven were novel; no haplotypes corresponded to haplotypes of Sotalia fluviatilis (online Appendix S3). Haplotype 3 has also been present in our good control of Sotalia guianensis, and corresponded to Sotalia guianensis Hap11 (GenBank #AY842456) of Cunha et al. (2005), and HapB (GenBank #EF027064) and HapC (GenBank #EF027065) of Caballero et al. (2007). When you look at the cytochrome b sequences we observed five Sotalia haplotypes (GenBank #EU022545–EU022549) that corresponded to Sotalia guianensis (online Appendix S4). The most common haplotype is just like the complete cytochrome b haplotype of Sotalia guianensis reported by Cunha et al. (2005) whereas three other haplotypes corresponded to haplotypes reported by Caballero et al. (2007); one haplotype ended up being novel.
