Indirect food web interactions affect the predation by Pine Marten on the nests of Tengmalm?s Owls according to the alternative prey hypothesis

Original language description

Although population cycles of rodents are geographically widespread and found in a number of rodent species, higher-order food web interactions mediated by predator-rodent dynamics have primarily been described in boreal and arctic biomes. During periodsof low rodent abundance, predators may switch from rodents to alternative prey, which may directly and indirectly affect other predators. Based on a long-term dataset, we assessed the frequency of Pine Marten Martes martes predation on the nests of Tengmalm?s Owl Aegolius funereus during periods of fluctuating rodent abundance in Central Europe. We found that (i) the number of nests predated by Pine Marten was positively correlated with the annual number of nests available, (ii) the probability of owlnest predation by Pine Marten decreased with increasing spring abundance index of Apodemus mice, but was not related to the abundance index of Myodes and Microtus voles, and pooled rodent abundance or (iii) functional age of the nestbox.
