The "Interactions" project is a long term effort devoted to the study of cyclic predator-prey interactions in changing arctic terrestrial communities (main target species are lemmings, arctic foxes, stoat, snowy owl, skuas and shorebirds). It started in 2010 in NE Greenland, with a close collaboration between 3 teams and study sites (Hochstetter, Zackenberg and Karupelv Valley) and was extended to 12 Arctic sites in 2016 (3 x Greenland, 3 x Russia, 4 x Canada, 1x Alaska and 1 x Sweden).
The current project at Hochstetter Forland is mainly supported by the French Polar Institute (IPEV). It started in 2010 and will last at least until 2018.
Field work is organizer jointly by the University of Burgundy (France) and the NGO "Groupe de rencheche en écologie Arctique (Arctic Ecology Research Group).
