摘要: The wolverine (Gulo gulo) hunts and scavenges for food. We examined how the presence of a semi-domesticated reindeer (Rangifer tarandus tarandus) influences diet breeding female wolverines in Finland. compared dietary composition management area (northern Finland) with that outside this (eastern by analyzing 421 scats collected from six active dens northern Finland four eastern during 2004–2006. occurrence food sources was assessed both areas using logistic mixed-effects models. Diet breadth per study also calculated. As expected, most important source (66 %) Mountain hares (Lepus timidus) were second item (16 %). Wolverines utilized grouse (7 %), small rodents (6 moose (Alces alces; 4 their diet. In Finland, prey species (55 while comprised mountain (13 domestic pigs (Sus scrofa; 13 (11 (2 included more less reindeers than niche did not differ between areas. shifted to 55 % 0 reindeer; 66 Our highlights role ungulates wolverines. low density medium-sized ungulates, scavenging wolf- human-killed carcasses on feeding sites plays an essential acquisition
