  1. 11. Applying emerging genetic methods to wild model systems

    Författare :Ida-Maria Blåhed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Genetic material is an invaluable source of information for assessments of wild populations. By using information derived from genetic markers, individuals can be identified and tracked over time, enabling studies of a wide range of behavioral, ecological, and evolutionary processes.

  3. 12. The use of highway crossings to maintain landscape connectivity for moose and roe deer

    Författare :Mattias Olsson; Per Widén; Anthony Clevenger; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wildlife crossings; Barrier effect; habitat selection; ecoduct; moose; roe deer; connectivity; conservation; overpass; underpass; highway; exclusion fencing; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective highway crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions.

  4. 13. Impacts of multi-species deer communities on boreal forests across ecological and management scales

    Författare :Sabine Pfeffer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : During the past decades, the population density and distribution of deer (Cervidae) has increased across Europe. Particularly in Sweden, this led to an increased cooccurrence of several deer species in landscapes highly dominated by humans. LÄS MER

  5. 14. The return of the wolf : effects on prey, competitors and scavengers

    Författare :Camilla Wikenros; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Apex predators may have both direct and indirect effects on other species through predation and competition. I investigated the effects of wolves (Canis lupus) on prey species, competitors (including humans) and the scavenging guild after the re-colonization by wolves of the Scandinavian Peninsula. LÄS MER

  7. 15. Indirect effects of moose on the birds and the bees

    Författare :Karen Marie Mathisen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Large herbivores are important drivers of ecosystem processes, affecting plant species richness and composition, primary productivity, habitat structure as well as nutrient cycling. Large herbivore activities may therefore have important indirect effects on other plants and animals in the same ecosystem. LÄS MER
