Скачать или смотреть A "Wallace Line" of the north? British Columbia as a centre for the study of bird diversification

Alfred Russel Wallace would have been fascinated by western Canada, where there are many narrow contact zones between related western and eastern forms of birds, many of which hybridize extensively where they meet. UBC's own Dr. Darren Irwin, an Associate Professor in Zoology, will discuss how we can use these contact zones to learn about the processes that have shaped the biodiversity around us today. These include biogeographic processes such as Ice Age glaciations, as well as evolutionary processes such as natural selection and behavioral evolution.

You will learn how seasonal migratory routes reflect ancient population expansions, how song evolution is central to the evolution of new species such as the Pacific Wren, and how our understanding of these patterns is important for the future conservation of birds.
