Presentation Transcript

  1. Microsatellite analysis ofBowhead whales (Baleana mysticetus) from the Bering-Chukchi-Beaufort Seas with regards to population stock structure and genetic bottlenecks Ryan M. Huebinger, John C. Patton, John C. George, Robert S. Suydam, Geof H. Givens, Lianne Postma and John W. Bickham

  2. Bowhead stocks • Five identified stocks • Spitsbergen • Davis Strait • Hudson Bay • Okhotsk Sea • Bering-Chukchi-Beaufort Seas (BCBS) Sea of Okhotsk Bering Sea Spitsbergen Beaufort Sea Davis Strait Hudson Bay

  3. Barrow

  4. Previous work • 11 microsatellite loci on 207 individuals from BCB • Jorde et al. (2004) detected potential population structure with in BCB (Oslo Bump) • Mitochondrial analysis was unable to detect population structuring within BCB (LeDuc et al., 2006)

  5. New Data • 22 Microsatellite Loci developed specific for Bowheads • 307 individuals from BCB • 65 individuals from Sea of Okhotsk • 50 individuals from Igloolik, Canada

  6. Analyses • Fst’s calculated utilizing FSTAT (Goudet, 2004) • STRUCTURE (Pritchard et al., 2000 ) • BOTTLENECK v 1.2.1 (Cornuet and Luikart, 1996) • Oslo Bump analysis (Givens and Ozaksoy, 2006)

  7. Fst values • Strata Fst 95% C • Canada vs. Okhotsk 0.057 (0.034, 0.089) • BCB vs. Okhotsk 0.036 (0.027, 0.045) • BCB vs. Canada 0.026 (0.007, 0.061) • Barrow vs. St. Lawrence Island 0.002 (-0.001, 0.006)

  8. STRUCTURE Results K=3 K=4 K=5

  9. Oslo Bump analysis

  10. Bottleneck • No significant genetic bottleneck was detected
