Title:Reproduction and migration at the top of the world: Lessons from arctic-breeding songbirds
Date:Friday, 23 February 2018
Location:Murie Life Science Bldg, Murie Auditorium.
Host:Cory Williams


With climate change, the Arctic is one of the most rapidly warming regions of the world. It is also the breeding grounds for millions of migratory songbirds. Birds that migrate to breed in the Arctic must time activities such as migration, reproduction, and molt to take advantage of favorable weather conditions and seasonal resource pulses. With global climate change, there is concern that migratory species may not adjust timing of these life history events to match changed environmental conditions. This talk focuses on the relationship between reproductive timing and reproductive success in white-crowned sparrows (Zonotrichia leucophrys gambelli) breeding on the North Slope of Alaska and discusses implications of findings for future climate change in the Arctic.

About the Speaker:

I work at the intersection of physiology, ecology, and behavior to understand how animals cope with seasons in an era of rapid global climate change. I received my PhD from University of California, Davis working with Drs. John Wingfield and Thomas Hahn studying reproduction and migration in white-crowned sparrows in arctic Alaska. I am currently a postdoctoral fellow at University of Alaska, Fairbanks with Cory Williams studying neurobiology of seasonality in arctic ground squirrels.
