  1. 1. Common Guillemots Uria aalge Alter Trip Patterns During Breeding

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Mica Bohacek; [2022]
    Keywords : Common Murre; Stora Karlsö; trip duration; trip frequency; central-place foragers; feeding rate; time-budget;

    Abstract : Seabirds are facing immense pressures, primarily induced by competition with commercial fisheries; this is of considerable concern due to the critical role that they play in marine food webs and their invaluable function as bioindicators. In this thesis, I studied the temporal change in trip duration for the Common Guillemot Uria aalge, a circum-arctic seabird species. READ MORE

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

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

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

    Abstract : 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. Population ecology of golden eagles (Aquila chrysaetos) using remote cameras

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

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

    Abstract : 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.

  6. 5. The effect of nest box temperature on the breeding success of Pied Flycatchers (Ficedula hypoleuca) in northern Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Jorina Boer; [2018]
    Keywords : pied flycatcher; Ficedula hypoleuca; temperature; breeding success; microclimate; nest box;

    Abstract : Benefits in terms of breeding success might arise from selecting nest sites with warmer thermal conditions. These energetic gains can subsequently be invested in increased breeding success by both parents and their nestlings. READ MORE
