  2. 1. Habitat selection and breeding ecology of golden eagles in Sweden

    Author : Edward Moss; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The red-listed Golden Eagle (Aquila chrysaetos) population is estimated between 1200-1400 reproductive individuals in Sweden. This population is unusual as eagles predominantly nest in trees unlike most others that prefer cliffs. READ MORE

  4. 2. Deciduous tree occurrence and large herbivore browsing in multiscale perspectives

    Author : Gunilla Cassing; Larry Greenberg; Christina Skarpe; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aspen; rowan; sallow; GIS; browsing; landscape; forest management; Biology; Biologi;

    Abstract : Aspen ( Populus tremula), rowan (Sorbus auquparia) and sallow (Salix caprea) are deciduous tree species of low economic value for forestry and contribute to biodiversity of boreal forests. The species are rare in managed forest landscapes, and severely browsed by moose. READ MORE

  5. 3. 'O neighbour, where art thou?' : spatial and social dynamics in wolverine and lynx, from individual space use to population distribution

    Author : Malin Aronsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The organisation of individuals in space and time influences population structure and dynamics, and is important for our understanding of animal ecology. The aim of this thesis is to gain an increased understanding of the mechanisms driving the abundance and distribution of solitary carnivores, from individual space use to population-level distribution.

  6. 4. Local baseline knowledge for conservation and restoration of degraded ecosystems in Ecuador

    Author : Ana Mariscal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Deforestation and land-use changes are a major threats to native ecosystem in many tropical countries, including Ecuador– one of the biodiversity hotspots in the world. In tropical Andean countries, natural ecosystems change over small spatial scales. READ MORE

  7. 5. The use of highway crossings to maintain landscape connectivity for moose and roe deer

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

    Abstract : 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.
