    Sammanfattning : The Arctic has long been perceived as a static, timeless place of shielded wilderness. This perception extended to the reindeer as both part of the Arctic environment and of traditional Indigenous livelihoods. LÄS MER

  3. 2. Selection, Maternal Effects and Inbreeding in Reindeer Husbandry

    Författare :Lars Rönnegård; Högskolan Dalarna; []
    Nyckelord :breeding programme; communal grazing; randombred populations; Rangifer tarandus tarandus; semidomestic reindeer; gene flow; reindeer; animal breeding; gene flow; random mating; breeding methods; genetic inheritance; population structure; extensive husbandry; sweden;

    Sammanfattning : In extensive grazing systems where several owners’ flocks are allowed to mix, selection strategies will also interact, due to gene flow between flocks. The aim of the thesis was to analyse breeding schemes in terms of genetic gain and rate of inbreeding (?F), given the complexity of ownership and interaction of selection strategies within a mixing reindeer population.

  5. 4. Top-down and bottom-up effects in a Fennoscandian tundra community

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; consumer-resource interactions; exclosures; food web dynamics; grey-sided voles; lemmings; NPK-fertilization; plant defences; reindeer; soil microbes; vertebrate grazing;

    Sammanfattning : The objective of this thesis was to investigate the effects of mammalian grazers, such as microtine rodents and reindeer, (top-down effects) and nutrient availability (bottom- up effects) on the plant community of a tundra heath.I conducted a large-scale fertilization experiment and studied the impact of grazers using exclosures.

  7. 5. Towards adaptive management of reindeer grazing resources

    Författare :Anna Olofsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis aims to create a scientifically founded proposal for improvement of optimal and sustainable use of reindeer pasture resources by an adaptive management approach. Hence, the adaptive management concept is reviewed and discussed with specific reference to reindeer husbandry. LÄS MER
