    • Agricultural grasslands buffer density effects in red deer populations 

      Mysterud, Atle; Langvatn, Rolf; Meisingset, Erling L.; Rivrud, Inger Maren (Peer reviewed; Journal article, 2022-12-29)
      Population densities of several cervid species have increased in recent decades in North America and Europe, and cervids frequently eat and damage agricultural crops. Competition and depletion of natural food resources are ...

    • Effect of legal regulation of supplemental feeding on space use of red deer in an area with chronic wasting disease 

      Mysterud, Atle; Rivrud, Inger Maren; Brekkum, Øystein; Meisingset, Erling L. (Peer reviewed; Journal article, 2022-12-12)
      Supplemental feeding of cervids during winter is a widespread management practice, but feeding may increase the risk of disease transmission. Therefore, legal regulations to limit supplemental feeding are often implemented ...

    • Estimating and managing broad risk of chronic wasting disease spillover among cervid species 

      Mysterud, Atle; Solberg, Erling Johan; Meisingset, Erling L.; Panzacchi, Manuela; Rauset, Geir Rune; Strand, Olav; Van Moorter, Bram; Rolandsen, Christer Moe; Rivrud, Inger Maren (Peer reviewed; Journal article, 2023-09-10)
      The management of infectious wildlife diseases often involves tackling pathogens that infect multiple host species. Chronic wasting disease (CWD) is a prion disease that can infect most cervid species. CWD was detected in ...

    • Future suitability of habitat in a migratory ungulate under climate change 

      Rivrud, Inger Maren; Meisingset, Erling L.; Loe, Leif Egil; Mysterud, Atle (Peer reviewed; Journal article, 2019-03-20)
      With climate change, the effect of global warming on snow cover is expected to cause range expansion and enhance habitat suitability for species at their northern distribution limits. However, how this depends on landscape ...

    • Heritability of head size in a hunted large carnivore, the brown bear (Ursus arctos) 

      Rivrud, Inger Maren; Frank, Shane; Bischof, Richard; Mysterud, Atle; Steyaert, Sam; Hertel, Anne Gabriela; Hagen, Snorre; Eiken, Hans Geir; Swenson, Jon; Zedrosser, Andreas (Journal article; Peer reviewed, 2019)
      Wild animal populations experience selection pressures from both natural and anthropogenic sources. The availability of extensive pedigrees is increasing along with our ability to quantify the heritability and evolvability ...

    • Implications of the forage maturation hypothesis for activity of partially migratory male and female deer 

      Debeffe, Lucie Isabelle; Rivrud, Inger Maren; Brekkum, Øystein; Meisingset, Erling L.; Mysterud, Atle (Journal article; Peer reviewed, 2017-12-21)
      Partial migration is common in a large variety of taxa in seasonally variable environments. Understanding the mechanisms underlying migration is important, as migration affects individual fi tness. Migratory herbivores ...

    • Interaction effects between weather and space use onharvesting effort and patterns in red deer 

      Rivrud, Inger Maren; Meisingset, Erling L.; Loe, Leif Egil; Mysterud, Atle (Journal article; Peer reviewed, 2014)
      Most cervid populations in Europe and North America are managed through selective harvesting, often with age‐ and sex‐specific quotas, with a large influence on the population growth rate. Less well understood is how ...

    • Sex-specific differences in spring and autumn migration in a northern large herbivore 

      Debeffe, Lucie Isabelle; Rivrud, Inger Maren; Meisingset, Erling L.; Mysterud, Atle (Journal article; Peer reviewed, 2019-04-16)
      Ongoing global warming is now affecting migratory cycles in a large variety of taxa in seasonally variable environments. Disruption of migratory systems can cause population decline and affect ecosystem function across the ...

    • Spatial clustering by red deer and its relevance for management of chronic wasting disease 

      Mysterud, Atle; Skjelbostad, Isa Nergård; Rivrud, Inger Maren; Brekkum, Øystein; Meisingset, Erling L. (Peer reviewed; Journal article, 2021-04-28)
      Herbivores like cervids usually graze on widely scattered forage, but anthropogenic food sources may cause spatial revisitation and aggregation, posing a risk for transmission of infectious diseases. In 2016, chronic wasting ...

    • Spatial mismatch between management units and movement ecology of a partially migratory ungulate 

      Meisingset, Erling L.; Loe, Leif Egil; Brekkum, Øystein; Bischof, Richard; Rivrud, Inger Maren; Lande, Unni Støbet; Zimmermann, Barbara; Veiberg, Vebjørn; Mysterud, Atle (Journal article; Peer reviewed, 2017-09-24)
      Population-level management is difficult to achieve if wildlife routinely crosses administrative boundaries, as is particularly frequent for migratory populations. However, the degree of mismatch between management units ...

    • The role of landscape characteristics for forage maturation and nutritional benefits of migration in red deer 

      Mysterud, Atle; Vike, Brit Karen; Meisingset, Erling L.; Rivrud, Inger Maren (Journal article; Peer reviewed, 2017-05-12)
      Large herbivores gain nutritional benefits from following the sequential flush of newly emergent, high-quality forage along environmental gradients in the landscape, termed green wave surfing. Which landscape characteristics ...
