      Madslien, Knut Ivar Engesæter; Stubsjøen, Solveig Marie; Viljugrein, Hildegunn; Ytrehus, Bjørnar; Solberg, Erling Johan; Kapronczai, Luciene; Mysterud, Atle; Godfroid, Jacques; Janz, David M.; Cattet, Marc (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-01)
      The deer ked (<i>Lipoptena cervi</i>), a hematophagous ectoparasite of cervids, is currently spreading in Scandinavia, and the moose (<i>Alces alces</i>) is its main host. However, little is known about the impact of deer keds on moose. We analyzed the hair cortisol concentration (HCC) from 262 moose harvested in the fall in relation to age class, sex, body mass (BM), and deer ked infestation ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-24)
      Arctic ungulates are experiencing the most rapid climate warming on Earth. While concerns have been raised that more frequent icing events may cause die‐offs, and earlier springs may generate a trophic mismatch in phenology, the effects of warming autumns have been largely neglected. We used 25 years of individual‐based data from a growing population of wild Svalbard reindeer, to test how warmer ...
