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

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : 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. READ MORE

  2. 2. Vegetation structure and interactions on mires

    University dissertation from Crister Albinsson, Dept of Natural Sciences, Högskolan i Kalmar, Box 905, S-391 29 Kalmar, Sweden

    Author : Crister Albinsson; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soligenous water supply; sloping fen; ordination; niche breadth; Narthecium ossifragum; liverwort; light competition; life strategy; hepatic; environmental gradient; classification; Association analysis; autecology; southern Sweden; Sphagnum; vegetation; Plant ecology; Växtekologi;

    Abstract : 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. READ MORE

    Abstract : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. READ MORE

  5. 5. Analyzing Vegetation Trends with Sensor Data from Earth Observation Satellites

    University dissertation from Department of Physical Geography and Ecosystem Science, Lund University

    Author : Sadegh Jamali; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change detection; Satellite sensor data; Time series analysis; Vegetation dynamics; Vegetation index;

    Abstract : Abstract This thesis aims to advance the analysis of nonlinear trends in time series of vegetation data from Earth observation satellite sensors. This is accomplished by developing fast, efficient methods suitable for large volumes of data. READ MORE
