  1. 1. A field-based estimation of eagle predation and scavenging on reindeer calves : towards mitigating human-wildlife conflicts

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Aemilius Johannes Van Der Meiden; [2023]
    Nyckelord :aquila chrysaetos; haliaeetus albicilla; rangifer tarandus; predation; repelling; human-wildlife conflict;

    Sammanfattning : Eagle predation on semi-domesticated reindeer (Rangifer tarandus) calves, both golden (Aquila chrysaetos) and white-tailed eagle (Haliaeetus albicilla) is a well-known issue in Sweden. However, there is a knowledge gap regarding the balance between scavenging and hunting and the role that each of the eagle species has in this issue. LÄS MER

  3. 2. Eyes in the nest : breeding phenology of Golden Eagles characterized using remote cameras

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Richard Larsson; [2020]
    Nyckelord :Golden eagle; breeding; Aquila chrysaetos; camera trap; phenology; Sweden;

    Sammanfattning : In situ monitoring of raptor breeding ecology with field personnel is costly, difficult and demanding. Installing camera traps in raptor nests can provide researchers with diverse information and long-term monitoring. Furthermore, it allows for relatively cheap data collection. LÄS MER

  4. 3. Dietary preferences of Golden eagles (Aquila chrysaetos) in Sweden : a camera trap approach

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Tomas Melin; [2020]
    Nyckelord :Aquilla chrysaetos; breeding; camera trap; Golden eagle; nestling; prey; Sweden;

    Sammanfattning : Food availability and suitable habitat are necessary for reproductive success of raptors. Monitoring these variables may therefore provide important insights on fitness and population dynamics of species such as the golden eagle (Aquila chrysaetos), which are often very difficult to monitor.

  5. 4. Not everything that glitters is gold : does linear infrastructure create an ecological trap for golden eagles?

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Michelle Etienne; [2020]
    Nyckelord :HIREC; animal ecology; animal movement; animal behaviour; integrated step selection function; wildlife traffic accidents; maladaptive behaviour; fitness; habitat selection;

    Sammanfattning : Animals can be caught in an “ecological trap” when they select for seemingly attractive habitats at the expense of their fitness. This maladaptive behaviour is often a consequence of human induced rapid changes in their natal environment, such as the development of linear infrastructure, where roads and railways create novel feeding conditions through traffic induced mortality of other species and powerline areas provide perching or nesting sites.

  7. 5. Population ecology of golden eagles (Aquila chrysaetos) using remote cameras

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Andressa Ludovico Aoki Dahlén; [2019]
    Nyckelord :golden eagle; camera traps; demographic parameters; fledging parameters; survival;

    Sammanfattning : The golden eagle populations have been studied across their range but basic demographic information is missing for a large part of their range. As an apex predator and scavenger, eagles are essential to the ecosystems they inhabit. In this study I analyzed pictures from installed camera traps around eagle nests in six counties in Sweden.
