      We studied the simultaneous activity patterns of a breeding wolf, Canis lupus, pair and five adult moose, Alces alces, cows from April to November 2004 in a wolf territory in southeastern Norway. All study animals were GPS ...

    • Behavioral responses of wolves to roads: scale-dependent ambivalence 

      Zimmermann, Barbara; Nelson, Lindsey; Wabakken, Petter; Sand, Håkan; Liberg, Olof (Journal article; Peer reviewed, 2014)
      Throughout their recent recovery in several industrialized countries, large carnivores have had to cope with a changed landscape dominated by human infrastructure. Population growth depends on the ability of individuals ...

    • Evaluation of Medetomidine-Ketamine and atipamezole for reversible anesthesia of free-ranging gray wolves (Canis lupus) 

      Arnemo, Jon Martin; Evans, Alina L.; Ahlqvist, Per; Segerström, Peter; Liberg, Olof (Journal article; Peer reviewed, 2013)
      Twenty-eight anesthetic events were carried out on 24 free-ranging Scandinavian gray wolves (Canis lupus) by darting from a helicopter with 5 mg medetomidine and 250 mg ketamine during winter in 2002 and 2003. Mean6SD ...

    • Genetic signature of immigrants and their effect on genetic diversity in the recently established Scandinavian wolf population 

      Åkesson, Mikael; Flagstad, Øystein; Aspi, Jouni; Kojola, Ilpo; Liberg, Olof; Wabakken, Petter; Sand, Håkan (Peer reviewed; Journal article, 2021)
      Transboundary connectivity is a key component when conserving and managing animal species that require large areas to maintain viable population sizes. Wolves Canis lupus recolonized the Scandinavian Peninsula in the early ...

    • Genomic consequences of intensive inbreeding in an isolated wolf population 

      Kardos, Marty; Åkesson, Mikael; Fountain, Toby; Flagstad, Øystein; Liberg, Olof; Olason, Pall; Sand, Håkan; Wabakken, Petter; Wikenros, Camilla; Ellegren, Hans (Journal article, 2017)
      Inbreeding (mating between relatives) is a major concern for conservation as it decreases the fitness of offspring and can increase the extinction risk of populations. While pedigrees have traditionally been used to measure ...

    • Let’s stay together? Intrinsic and extrinsic factors involved in pair bond dissolution in a recolonizing wolf population 

      Milleret, Cyril; Wabakken, Petter; Liberg, Olof; Åkesson, Mikael; Flagstad, Øystein; Andreassen, Harry Peter; Sand, Håkan (Journal article; Peer reviewed, 2016)
      For socially monogamous species, breeder bond dissolution has important consequences for population dynamics, but the extent to which extrinsic or intrinsic population factors causes pair dissolution remain poorly understood, ...

    • Monitoring of wolves in Scandinavia 

      Liberg, Olof; Aronson, Åke; Sand, Håkan; Wabakken, Petter; Maartmann, Erling; Svensson, Linn; Åkesson, Mikael (Journal article; Peer reviewed, 2012)
      The Scandinavian wolf population is jointly monitored by Norwegian and Swedish authorities. Monitoring is made annually. Wolves are classified in different categories. Family groups ( 3 animals sharing a territory), ...

    • Poaching-related disappearance rate of wolves in Sweden was positively related to population size and negatively to legal culling 

      Liberg, Olof; Suutarinen, Johanna; Åkesson, Mikael; Andrén, Henrik; Wabakken, Petter; Wikenros, Camilla; Sand, Håkan (Peer reviewed; Journal article, 2020-03-14)
      Poaching is an important limiting factor for many large carnivore populations worldwide and the effect that legal culling has on poaching rate on wolf (Canis lupus) is debated. We used data linked to population monitoring ...

    • Predator-dependent functional response in wolves: from food limitation to surplus killing 

      Zimmermann, Barbara; Sand, Håkan; Wabakken, Petter; Liberg, Olof; Andreassen, Harry Peter (Journal article; Peer reviewed, 2014)
      The functional response of a predator describes the change in per capita kill rate to changes in prey density. This response can be influenced by predator densities, giving a predator-dependent functional response. In ...

    • Sarcoptic mange in the Scandinavian wolf Canis lupus population 

      Fuchs, Boris; Zimmermann, Barbara; Wabakken, Petter; Bornstein, Set; Månsson, Johan; Evans, Alina L.; Liberg, Olof; Sand, Håkan; Kindberg, Jonas; Ågren, Erik O.; Arnemo, Jon Martin (Journal article; Peer reviewed, 2016)

    • Shoot, shovel and shut up: cryptic poaching slows restoration of a large carnivore in Europe 

      Liberg, Olof; Chapron, Guillaume; Wabakken, Petter; Pedersen, Hans Christian; Hobbs, N. Thompson; Sand, Håkan (Journal article; Peer reviewed, 2012)
