  3. 3. Topographic controls of drought impact on Swedish primary forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johanna Asch; [2021]
    Keywords : Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

    Abstract : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. READ MORE

    Abstract : Träd i tropiska våtmarker har uppmärksammats som en viktig källa till regionala och globala metan (CH4) utsläpp, då träd fungerar som utsläppskanaler för metan som bildas i sedimenten. Dock finns det en osäkerhet gällande säsongsvariation och rumslig variation samt mängden CH4 utsläpp från träd, eftersom kunskapen kring regionala flöden är begränsad. READ MORE
