Sources for specimens

Burke Museum, University of Washington

• Demonstrated well-preserved tissue collection in previous collaboration

• Houses voucher specimens for tissues

• Boasts an “unsurpassed modern collection from many localities throughout the former Soviet Union and Mongolia”

Specimen selection

No formal list has been decided on yet for the Palearctic

• “A Field Guide to the Birds of Russia” was used as a guide to pick samples

• Species were reviewed in systematic order, searched for in the Burke’s online database (including specimens collected in Russia, Mongolia, and Kazakhstan)

DNA sources

Feathers are not useful for initial sampling effort

Museums are the ideal starting point

Maintaining a 96–well format facilitates high throughput

Receive tissues in “Matrix” boxes to help maintain organization

Summary:

213 of 234 species 626 sequenced of 803 specimens 2.9 replicates per species

Mean intraspecific distance = 0.52% (versus North American 0.23%)

Mean congeneric distance = 8.83% (versus North American 5.9%)

Results: Taxon resolution

Only 1 “lumped” pair of taxa has been found:

1 Anatidae1 Scolopacidae1 Columbidae1 Caprimulgidae

2 Picidae2 Hirundinidae1 Troglodytidae5 Turdidae

14 Species with splits

Palearctic vs Nearctic

• Comparisons to Nearctic conspecifics is variable• NO Palearctic species LUMPS with a Nearctic species

Preliminary points

1. Patterns of divergence emulate those observed in the North American birds

2. The addition of Palearctic birds does not confuse the results from the original dataset

New contributions

Zoological Museum of Moscow University (Mikhail Kalyakin):

• An additional 65 species (299 species in total)

• An additional 352 specimens (1,155 specimens in total)
