Medium-sized predators sometimes switch to alternative prey species as their main prey declines. Our objective of this study was to test the alternative prey hypothesis for a medium sized predator (red fox, Vulpes vulpes), a small cyclically fluctuating main prey (microtine voles) and larger alternative prey (roe deer fawns, Capreolus capreolus). We used long-term time series (28 years) on voles, red fox and roe deer from the Grimso Wildlife Research Area (59°40′N, 15°25′E) in south-central… CONTINUE READING
