  2. 16. Interactions between ungulates and forest insects

    Author : Michelle Nordkvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In forest ecosystems ungulates and insect herbivores often co-occur and utilise the same host trees. Herbivores that share a host plant can indirectly affect each other through plant induced responses. Such changes may affect plant growth, interactions with other species, and population dynamics.

  4. 17. Promoting natural regeneration of oak by manipulating disturbance

    Author : Linda Petersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Oak regeneration is thought to be promoted by natural disturbance and past management practices that create semi-open conditions, such as periodic livestock grazing and lowintensity fire. The overall goal of this thesis was to examine whether disturbance factors can promote natural oak regeneration. READ MORE

  5. 18. Indirect effects of moose on the birds and the bees

    Author : Karen Marie Mathisen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 19. Busted by the bite : Molecular evidence of cryptic foraging behaviors in large herbivores

    Author : Ruth Nichols; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Large herbivores are charismatic species known to engineer ecosystems through a variety of effects. Conflicts can sometimes arise when these effects are undesirable. However, without detailed knowledge on herbivore selectivity for landscapes, patches and plants, these positive and negative effects remain difficult to predict. READ MORE

  7. 20. Increased resilience in managed boreal forests : Controlling damage by spruce bark beetle and moose in Sweden

    Author : Matilda Lindmark; Bengt-Gunnar Jonsson; Erika Wallin; Jan-Olov Weslien; Mittuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Most of the forests growing in Europe today have been planted, or heavily affected, by humans. This is because the forest industry provides crucial raw materials for diverse products, including timber, pulp and paper, cellulose-based substances and renewable energy sources. READ MORE
