  2. 2. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

    Författare :Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. LÄS MER

  3. 3. Vegetation structure and interactions on mires

    Författare :Crister Albinsson; []

    Sammanfattning : The distribution of sloping fens in southern Sweden was mapped, their vegetation sampled and related to the environmental variables recorded. This mire type is distributed further to the east than previously reported, namely around the highest post-glacial limit of the sea level. LÄS MER
