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

    Author : Edward Moss; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    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

  2. 2. Irrigation and horticultural practices in ornamental greenhouse production : implementation of scientific knowledge into irrigation practices and methods

    Author : Klara Löfkvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Irrigation in greenhouse pot plant production is traditionally managed using a tactile perceptual method. This method, in this thesis called ‘the golden grip’, is based on the grower’s experiential knowledge where water requirement is determined by combining the estimated weight of the pot (both growing medium and plant) with factors such as plant age, developmental stage and size in combination with prevailing and future climate conditions.

  3. 3. Predator-prey interactions of raptors in an arctic environment

    Author : Jesper Nyström; Anders Angerbjörn; A. Rolf Ims; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology of raptors; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : This thesis concerns the predator-prey interactions of three raptor species in a Swedish arctic community: the gyrfalcon (Falco rusticolus), the rough-legged buzzard (Buteo lagopus) and the golden eagle (Aquila chrysaetos). The gyrfalcon behaved like a highly specialised ptarmigan (Lagopus spp.) predator. READ MORE

  4. 4. Phantom of the Neighbourhood : Longitudinal Studies on Area-based Conditions and Individual Outcomes

  5. 5. Diatom-rich sediment formation in lakes

    Author : Petra Zahajská; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon; silica; diatom; biogenic silica; lake; sediment; stable Si isotopes; Ge Si; Yellowstone; Northern Sweden;

    Abstract : Unicellular photosynthetic golden algae called diatoms are one of the most abundant silicifying organisms. Diatoms take up silicon and build their frustules, in the form of biogenic silica (BSi), which have high preservation potential, and thus are found in sediments. READ MORE
