Abstract
We estimated carcass density and determined cause of death in a peak-d ensity lemming, Lemnus lemnus, population at Finse, Norway. Of 74 reco vered carcasses, 80% had subcutaneous haematoma (blood underneath the skin) in the head region. though the skin on the skull most often appe ared unharmed. Thirty percent were apparently killed by a mustelid pre dator, while 51% were probably killed by corvids. Carcass density was 26.6 and 9.4 ha(-1) in good and poor lemming habitats, respectively.
