    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Elin Andersson Sjöholm; [2024]
    Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER

  3. 2. Temporary Halting of Wind Turbine Rotors toMitigate Effects on Birds

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ola Hedberg; [2024]
    Nyckelord :Bird; mitigation; effect; wind farm; turbine; wind power; halting; collision; risk; birds; power; generation;

    Sammanfattning : This study assesses the viability of temporarily halting wind turbine operations as amitigation measure to protect bird populations during migration periods. Conducted in thenorthern Baltic, it examines the migration patterns, timings, and altitudes of various birdspecies, aiming to identify the most critical times for implementing turbine stoppages.

    Författare :Lars Binger; Jakob Gruss; [2024]
    Nyckelord :Greek Sovereign Debt Crisis; Migration; Emigration; Synthetic Control Method; Influencing Factors;

    Sammanfattning : This study explores the patterns of emigration from Greece and migration rates within Greece in the aftermath of the Greek Sovereign Debt Crisis. Employing the Synthetic Control Method (SCM), we construct a hypothetical, counterfactual to Greece, the Synthetic Greece. Our key findings include a marked increase in emigration with emigration rates 0. LÄS MER

    Sammanfattning : Sparvugglan (Glaucidium passerinum) är en invasionsfågel som uppvisar årliga fluktuationer i sina invasioner vid Hammarö Fågelstation. Invasioner av denna art utlöses vanligtvis av brist på föda tidigt under hösten, vilket kan orsaka att hundratals fåglar migrerar på ett oförutsägbart sätt. LÄS MER
