  2. 2. Turning Night into Day : Does Skyglow affect Bat Activity and Timing of Emergence?

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Torge Gerwin; [2023]
    Keywords : Skyglow; Bats; Light pollution; Bat activity; Bat emergence; Riparian forest; Landscape composition; Multi-scale landscape; Landscape management; Sweden;

    Abstract : Artificial brightness of the night sky caused by the backscatter of artificial light in the atmosphere is a consequence of ongoing urbanization. Skyglow covers 88 % of Europe’s surface and poses significant threats to biodiversity. Extensive research on responses of bats to direct light pollution already revealed significant impacts.
