Tracking the movements and ecologies of Beringian creatures, past and present, using isotopes

Debate still swirls around the cause/s of animal extinctions from Beringia around the end of the last glaciation. Information regarding the ecologies of these past animals is sparse despite a rich fossil record from the region. In particular, past movement patterns of the Beringian mega-fauna are poorly understood. Join Matt Wooller as he describes how state-of-the-art isotope techniques combined with data gathered from modern creatures in Alaska (such as caribou, wood bison and even humble voles) are being used to better understand movement patterns and past ecologies of Beringian creatures such as the steppe bison and wooly mammoth.
Yukon Ice Patches: Leaving behind Yukon's own mini Jurassic Park?
Brittney Miller, MSc, Plant Biology

As Yukon’s ice patches have been shrinking, many interesting finds have been exposed, not least of which are 4,000 year old bryophytes (mosses, hornworts and liverworts) that can be regrown from spores and fragments. Under the ice, subglacial refugia not only preserve bryophyte species for regrowth in future millennia, but whole communities as well – communities that could possibly be our very own miniature Jurassic Park in the making. Join Brittney Miller as she explores the potential of exhumed bryophytes to establish, re-vegetate, and maintain diversity in alpine ecosystems.
Star Party: Yukon's Night Sky

9:30 pm Night sky viewing
On Sunday, October 22nd, Dr. Phil Plait & Dr. Christa van Laerhoven will discuss and dispel common misconceptions about the many fascinating objects in the Yukon night sky! Come discover secrets about the Aurora Borealis, our ever-changing Universe, and the many current, and near-future roles YOU can be a part of! Your moderator for the evening will be Jaclyn Semple, B.Sc, M.Sc of the Yukon College. This is a FREE presentation.
