    Author : Klara Hugosson; [2022-05-20]
    Keywords : ;

    Abstract : The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused by land use changes is well known. READ MORE

  3. 7. 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. 8. Nutrient Retention in Constructed Wetlands

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Johanna Kero; [2022]
