Data from: The fluctuating world of a tundra predator guild: bottom-up constraints overrule top-down species interactions in winter ...
Global warming is predicted to change ecosystem functioning and structure in Arctic ecosystems by strengthening top-down species interactions, i.e. predation pressure on small herbivores and interference between predators. Yet, previous research is biased towards the summer season. Due to greater ab...
