  2. 1. Trees and the environment : Possibilities and challenges in tree-ring research across spatial and temporal scales based on case studies in Sweden

    Author : Eva Rocha; Steffen Holzkämper; Björn Gunnarson; Anders Moberg; Martin De Luis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree rings; Sweden; climate variability; environmental monitoring; ring width; maximum latewood density; stem radial increment; ED-XRF; light rings; Physical Geography; naturgeografi;

    Abstract : The need to understand and quantify the magnitude and frequency of past and current environmental changes increased the demand for high-resolution proxy data across spatial and temporal scales. Due to their long lifespan and global distribution, trees provide a unique and continuous record of environmental variability. READ MORE

    Abstract : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. READ MORE

  5. 3. Tree Rings as Sensitive Proxies of Past Climate Change

    Author : Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

    Abstract : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. READ MORE
