1. Exposure and Carriage of West Nile Virus in feathered Iberian Scavengers
Master-uppsats, Uppsala universitet/Institutionen för ekologi och genetik; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Scavenging bird of prey have been abundant throughout the Mediterranean region for years, establishing a food acquisition relationship with human activities, their characteristics make them especially suitable for the recognition of dangerous environmental conditions. The West Nile Virus (WNV) considered the most widespread arbovirus has been previously discovered in our 3 species of studio. LÄS MER
2. Eyes in the nest : breeding phenology of Golden Eagles characterized using remote cameras
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : 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
3. Dietary preferences of Golden eagles (Aquila chrysaetos) in Sweden : a camera trap approach
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : 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.

4. The effect of urbanization on the characteristics of bird populations : current situation and future aspects
Kandidat-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : Tack vare människans allt mer progressiva utbredning utsätts många djurarter för nya miljöer som är helt skilda deras naturliga förhållanden. Fåglar är en av de grupper som har påverkats i allra högsta grad. En gradvis avtagande biodiversitet av fågelarter blir ett av resultaten av urbaniseringen. LÄS MER
5. STUDY OF REQUIREMENTS FOR POST-CONSTRUCTION AUTOMATED BIRD MITIGATION SYSTEMS FROM STAKEHOLDER’S PERSPECTIVE
Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The expansion of wind power comes with additional risks for bird populations, one of which is the collision with wind turbine components, mainly the rotating blades. In order to mitigate this risk, few systems on the market propose solutions with modules that deter the birds from the wind turbine or trigger the temporary shutdown of the turbines. LÄS MER
