  1. 1. Effect of tree age on masting signal in tree-ring chronologies of beech in southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Jeppe Van Der Lee; [2023]
    Keywords : beech; masting; masting signal; proxy; tree-ring chronologies; age; dominance; social position; southern Sweden; climate change; tree growth; regeneration success;

    Abstract : Masting is a synchronous and highly variable production of seeds in tree species. Masting may reflect a reproduction strategy to cope with seed predation. In beech, temperature is the cue controlling annual variability in seeding. Masting behaviour in beech typically begins around the age of 40 years. READ MORE

  3. 2. POSSIBLE TIMING OF THE TRANSITION FROM PRE-INDUSTRIAL TO INDUSTRIAL CLIMATE IN THE CENTRAL TO NORTHERN OF SWEDEN, BASED ON PROXY DATA FROM TREE-RINGS

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Mika Falkensjö Oppenheim; [2022-09-28]
    Keywords : Tree-ring; maximum latewood density MXD ; Scandinavia; pre-industrial; industrial climate;

    Abstract : Earth’s climate has varied through time, with orbital forcing as the most dominant force on the climate system the last million years, causing glacial-interglacial cycles. The last glacial period ended about 11.6 thousand years (kyr), ago and the last interglacial maximum around 6.5 kyr ago. READ MORE

  4. 3. Comparison of annual response to weather for Norway spruce (Picea abies) and Scots pine (Pinus sylvestris)

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Kristian Tufvesson; [2018]
    Keywords : Norway spruce; Scots pine; tree-ring width; climatic response; Southern Sweden;

    Abstract : Different tree species react differently to variation in climate. This relationship can be found by measuring how annual ring width correlates to different climate ariables. This information may be important as a basis for understanding how future forests may be altered by climate change. READ MORE

  5. 4. Inverkan av temperatur, nederbörd och genetik på årsrings- egenskaperna hos svensk gran(Picea abies.(L)Karst)

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Mattias Larsson; [2015]
    Keywords : veddensitet; sommarved; vårved; klimat; årsringsdensitet;

    Abstract : Den svenska granen(Picea abies (L.) Karst) har ett vidsträckt utbredningsområde med ett till synes varierande klimat som påverkar granens årsringsegenskaper på olika sätt. READ MORE

  6. 5. Permeability in surface treated Norway spruce samples- Effect of wood properties

    University essay from Institutionen för teknik, TEK

    Author : Josefin Nilsson; [2012]
    Keywords : Norway spruce; Picea abies; durability; water uptake; wood properties;

    Abstract : In Norway spruce there's a large natural variation in durability but knowledge about what is causing this variation is missing. In this thesis the focus were put into investigating how the water uptake ability was affected by the influence of heartwood versus sapwood and wood properties such as density and annual ring width.
