Tracking animal migration with stable isotopes

Tracking animal migration with stable isotopes Keith A. Hobson from Western University and Environment and Climate Change Canada, walks us through tracking animal migration with stable isotopes, starting with some background information. Animal migration is one of the most iconic of all natural phenomena and humans have marvelled at animals' ability to navigate over vast distances often under arduous conditions. Periodic to-and-fro migration is the most familiar form, and birds have clearly captured our imagination on that front with their conspicuous annual movements and arrivals between continents. However, how animals successfully move in this way is still not fully appreciated, and a full understanding will ultimately involve expertise from diverse disciplines.
