Species identification of non hatched embryos Choice of marker: mitochondrial 16S rDNA Sequenced 141-509 bp: 6 groups (haplotypes) Analyses: BLAST (GenBank) and distance Matsumoto, Oliveira-Marques, et al., in prep.
Salvatoria xanthops (50) Amazona aestiva/ Amazona ochrocephala (4) 213 bp of 16S rDNA Ara ararauna (3) Non psitacid(1) Matsumoto, Oliveira-Marques, et al., in prep.
Ara macao Ara chloroptera Ara militaris Ara ambigua Primolius maracana Primolius auricollis Primolius couloni Guarouba guarouba Diopsittaca nobilis Orthopsittaca manilata Ara ararauna Group 2 Ara glaucogularis Aratinga cactorum Ara severa Cyanopsitta spixii Anodorhynchus hyacinthinus 390 bp of 16S rDNA Ara ararauna (3)
Species identification of non hatched embryosConclusions The available 16S rDNA data base was informative to identify the species of the embryos. The species identification was confirmed in another lab that used another mitochondrial marker (cytochrome b). Would COI be a good marker? Building a COI database for Neotropical parrots and will test the same embryos.
COI sequence database for Neotropical parrots Master’s Degree student: Priscila F.M. Gonçalves (Dec 2006) Objective: construct the database and evaluate its usefulness for species identification (e.g. evaluate if genetic distances within and among taxa do not overlap)
