  1. 1. Conservation Genetics of Scandinavian Wolverines

    Författare :Eva Hedmark; Hans Ellegren; Lisette Waits; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; carnivores; conservation; genetic monitoring; molecular sexing; non-invasive genetic techniques; parentage analysis; tanning; Genetik; Gulo gulo; Genetics; Genetik;

    Sammanfattning : In this thesis, genetic methods for individual identification and sex determination of wolverines from non-invasive samples were developed and applied in genetic monitoring of Scandinavian wolverine populations. Paternity and mating system of wolverines were studied by combining genetic analysis with telemetry data. LÄS MER

  3. 2. Sociality in a solitary carnivore, the wolverine

    Författare :Fredrik Dalerum; Anders Angerbjörn; Kyran Kunkel; Stanley Boutin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sociality; carnivore; behaviour; ecology; spatial organisation; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The social organization of animal societies has important implications for several fields of biology, from managing wild populations to developing new ecological and evolutionary theory. Although much attention has been given to the formation and maintenance of societies of group living individuals, less is known about how societies of solitary individuals have been shaped and maintained.

  4. 3. Interactions between Eurasian lynx and wolverines in the reindeer husbandry area

    Författare :Jenny Mattisson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In conservation and management, carnivore species are often treated as isolated units, even though interspecific interactions can have important implications for the behaviour, demography and distribution of the species involved. In this thesis I used individual based GPS-location data to study interactions between two solitary predators in the reindeer husbandry area in Northern Scandinavia: The Eurasian lynx (Lynx lynx), an obligate predator, and the wolverine (Gulo gulo), an opportunistic predator and scavenger.

  5. 4. Anthropogenic impact on predator guilds and ecosystem processes : Apex predator extinctions, land use and climate change

    Författare :Marianne Pasanen Mortensen; Bodil Elmhagen; Francisco Palomares; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mesopredators; apex predators; top-down; bottom-up; interspecific killing; red fox; Eurasian lynx; grey wolf; wolverine; productivity; winter severity; cropland; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Humans affect ecosystems by changing species compositions, landscape and climate. This thesis aims to increase our understanding of anthropogenic effects on mesopredator abundance due to changes in apex predator status, landscape and climate. LÄS MER

  7. 5. Life and death in wolverines : linking demography and habitat for conservation

    Författare :Geir Rune Rauset; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Developing trustworthy conservation planning for endangered species requires a deep understanding of the variations of their populations in both space and time. I used individual-based long-term location and demographic data on wolverines (Gulo gulo) in Northern Sweden, and data on reproductions from the national monitoring systems of Norway and Sweden, to analyze how wolverine demography in Scandinavia is affected by variation in habitat and management policies.
