  1. Potential of DNA Barcode in South America Campinas, March 19-20, 2007 BARCODE AND FISH DIVERSITY IN AMAZONIA: THE CASE OF THE ELECTRIC FISH TRIBE STEATOGENINI Alves-Gomes, J. A. & Schmitt, R. Laboratory of Behavioral Physiology Instituto Nacional de Pesquisas da Amazônia, Brazil

  2. Gonorhynchiformes Cypriniformes Characiformes Siluriformes Gymnotiformes Anotophysi Otophysi Series Superorder Ostariophysi

  3. GYMNOTIFORM’S ELECTROGENIC AND ELECTROSENSORY SYSTEMS (EES)

  4. GYMNOTIFORMES ELECTRIC ORGAN DISCHARGES (EODs) ELECTROPHORIDAE HYPOPOMIDAE LFC - 2002 A. Batistella, 2003 PULSE TYPE RHAMPHICHTHYIDAE GYMNOTIDAE R. Bernhard, 2003 LFC - 2002 STERNOPYGIDAE APTERONOTIDAE http://www.amazonian-fish.co.uk/indexster.html WAVE TYPE R. Bernhard, 2003 EIGENMANNIDAE http://www.amazonian-fish.co.uk/indexster.html 6

  5. EODs are species specific Crampton & Hopkins 2005

  6. Sternopygus Gymnotus Electrophorus Rhamphichthys Gymnorhamphichthys Microsternarchus Brachyhypopomus Rhabdolichops Archolaemus Eigenmannia Distocyclus A. leptorhynchus Adontosternarchus Sternarchorhamphus Orthosternarchus A. albifrons Sternarchogiton Sternarchella Phylogeny of Gymnotiformes Ordem Siluriformes Genera Family Sternopygidae Gymnotidae Electrophoridae Steatogenini Rhamphichthyidae Hypopygus Steatogenys Hypopomidae Eigenmanniidae Apteronotidae

  7. Steatogenini until the early 90’s Hypopygus lepturus Hoedeman 1962 Steatogenys elegans Steatogenys duidae

  8. Color patterns in Hypopygus Nijssen & Isbrüker 1972

  9. Steatogenini during the 90’s Hypopygus lepturus Hoedeman 1962 Hypopygus neblinae Mago-Leccia 1994 Steatogenys

  10. Steatogenini during the 90’s / today Hypopygus lepturus Hoedeman 1962 Hypopygus neblinae Mago-Leccia 1994 Stegostenopos cryptogenes Triques 1997 Steatogenys

  11. Phylogeography in the rio Negro Basin

  12. STUDY AREA – COLLECTION SITES Jaradi Ibará Iahá Aduiá Irurabi Carabixi Mabarrá Quimicuri (Fonte: SigLab, Imagem de Satélite – Mr. Sid)

  13. 21a

  14. R. Bernhard, 2004 8e

  15. Steatogenys sp. Stegostenopos cryptogenes Hypopygus lepturus R. Bernhard, 2004 8a

  16. Maximum Parsimony (MP) • Maximum Likelihood (ML) • Distance DNA ANALYTICAL PROCEDURES: RAG 1 D

  17. RAG 1 MP/ML/Dist Stegostenopus Hypopygus neblinae A H. lepturus C D Steatogenys

  18. 12S16S Strict of ML/MP/Dist Stegostenopus H. neblinae A C H. lepturus D E Steatogenys

  19. 2792 2791 D-loop MP/HKY85/ML D-loop MP/ML/Dist H. lepturus D E H. neblinae S. elegans

  20. Is COI a good gene to detect the variation in electric fish?- Can we BARCODE them?

  21. Stegostenopus H. neblinae E D C 2792 2791 A COI - BARCODE MP H. lepturus Eigenmannia sp.

  22. Final considerations The Amazon fish biodiversity has been historically underestimated; COI can detect the intra- and inter-specific variation in Steatogenini; COI appears to be an efficient marker for electric fish species identification: we can BARCODE electric fish; The link between a padronized method (Barcode), biological collections and data management can benefit our general knowledge about biodiversity; BARCODE can be a important tool for biodiversity and conservation issues; CNPq funds for a project to barcode electric fish.
