  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

  4. 2. Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective

    Author : Peng Zhang; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central Scandinavia; climate variability; dendroclimatology; maximum latewood density; Medieval Climate Anomaly; model-proxy data comparison; Pinus sylvestris L.; temperature; tree-ring width;

    Abstract : To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution and can be precisely dated, have been widely used to infer past climate variability. READ MORE

  5. 3. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Author : Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Abstract : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. READ MORE

  6. 4. Spatiotemporal climate and atmospheric circulation variability in Asia inferred from tree rings

    Author : Andrea Seim; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asia; atmospheric circulation; Central Asia; dendroclimatology; growth-climate relationship; objectively classified weather types; teleconnections; tree-ring networks;

    Abstract : Observed 20th century warming trends accompanied by more frequent weather extremes such as droughts or intense rainfall events have consequences for societies and environments alike. In Asia, where the majority of the population depend on agricultural productivity, recent climate change is likely to increase societal hardships. READ MORE

  7. 5. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits

    Author : Johannes Edvardsson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

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