    Author : Linda Dimrå; [2022]
    Keywords : Bombus; Forest; Vaccinium Myrtillus; Landcover change;

    Abstract : The Swedish forest has been transformed during the last hundred years, from semi-open forest of multiple tree species to dense production forest of mainly spruce and pine. This has led to alterations of species composition in the forest floor, reducing coverage of dwarf shrubs like Vaccinium myrtillus (European blueberry). READ MORE

    Keywords : snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

    Abstract : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. READ MORE

  6. 20. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden

    Author : Amanda Lindgren; [2021-03-10]
    Keywords : acid sulphate soils; metal distribution; surface water; climate; physicochemistry;

    Abstract : Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presence of acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and the soils are today threatening many of the national environmental goals of Sweden. READ MORE
