Parking and Bus Getting around the town and UW campus is not hard. Bus routes run through the campus, for example #67, and a map is available at http://metro.kingcounty.gov/schedules/066/map.html Parking may be available at your hotel. Please inquire with your hotel about on-site parking. Daily parking permits can be purchased at the campus gates for $15 (6am-5pm, Monday-Friday), and Night permits for $5. Central Parking Garage charges a non- refundable $10 event rate, but other parking lots near Burke Museum or HUB don’t charge that fee.

Elizabeth, York College & The Graduate Center, City University of New York, 94 - 20 Guy R. Brewer Blvd, Jamaica, NY 11451, [email protected] Changes in sea ice and sea level over the Holocene dramatically impacted both habitat and dispersal routes for many species of marine mammals. We examined ancient DNA from gray whales and bowhead whales, two species of baleen whale that utilize Arctic and sub-Arctic habitats. The Atlantic gray whale represents the only known recent extinction of a great whale species or population from an ocean basin, but very little is known about its demographic history or its relationship to the extant Pacific populations. Our results show that the Pleistocene population in the Atlantic persisted through the last glacial maximum to the Holocene. Migrations between the Pacific and the Atlantic Ocean were climate-dependent, and occurred both during the Pleistocene prior to the last glacial period, and during the early Holocene immediately following the opening of the Bering Strait. We observe a decline in genetic diversity in the Atlantic gray whale population over an extended interval beginning in the mid-Holocene, perhaps precipitated by climatic or ecological causes. These results contrast with findings for bowhead whales, which show a high level of gene flow between Atlantic and Pacific stocks in the recent past. Unexpectedly, samples from the central Canadian Arctic show a much closer genetic relationship with modern Pacific stocks than with modern Atlantic stocks, supporting high gene flow between the central Canadian Arctic and the Beaufort Sea over the past millennium despite extremely heavy ice cover over much of this period. These results indicate that gray and bowhead whales responded differently to climatic changes in the Holocene, highlighting how complex ecologies in these species shape their response to climate. 10 WHAT THEY DID AFTER THEY GOT THERE: LIFE DURING THE TERMINAL PLEISTOCENE IN THE INTERMOUNTAIN WEST BECK, Charlotte, [email protected],
