Population dynamics of Arctic foxes at Karrak Lake

This study examines various aspects of the population dynamics of arctic foxes and how they vary with fluctuations in lemming abundance – the main food of arctic foxes in most of their range. Such information is increasingly important today when human alteration and environmental changes are affecting most ecosystems worldwide.
