  1. 1. Carbon Balance Implications of Forest Biomass Production Potential

    University dissertation from Östersund : Mid Sweden University

    Author : Bishnu Chandra Poudel; Mittuniversitetet.; [2014]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change;

    Abstract : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. READ MORE

  2. 2. Fire history and tree population dynamics in Białowieża Forest, Poland and Belarus

    University dissertation from Östersund : Mid Sweden University

    Author : Ewa Zin; Sveriges lantbruksuniversitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Fire history and fire regime parameters in relation to the long-term tree population dynamics were studied with dendroecological methods across coniferous habitats of Białowieża Forest (E Poland and W Belarus), a semi-natural European temperate woodland ecosystem. In four different studies various aspects of fire dynamics were explored by using nearly 1500 tree ring samples of Pinus sylvestris and Picea abies. READ MORE

  3. 3. Old-Growth Forests in the High Coast Region in Sweden and Active Management in Forest Set-Asides

    University dissertation from Sundsvall : Mid Sweden University

    Author : Jennie Sandström; Mittuniversitetet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coarse woody debris; Dead wood; Dendrochronology; Fire history; Forest conservation; Forest structure; Log; Meta-analysis; Pine heath forest; Prescribed burning; Saproxylic fungi; Saproxylic beetles; Snag; Wood-inhabiting fungi; Aktiv skötselmetod; Bevarandebiologi; Brandhistorik; Dendrokronologi; Död ved; Hällmarkstallskog; Lågproduktiv skog; Meta-analys; Naturvård; Naturvårdsbrand; Skogsstruktur; Solbelyst död ved; Stock; Torraka; Vedlevande svamp; Vedlevande insekter; Åldersstruktur;

    Abstract : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. READ MORE

  4. 4. Phosphorus availability and microbial respiration across biomes  from plantation forest to tundra

    University dissertation from Umeå : Umeå universitet, Institutionen för ekologi, miljö och geovetenskap

    Author : Camilla Esberg; Umeå universitet.; [2010]
    Keywords : phosphorus availability; microbial bioassay; soil respiration; microbial growth rate; Hedley fractionation; soil sorption; weathered soils; boreal forest; subarctic and tundra;

    Abstract : Phosphorus is the main limiting nutrient for plant growth in large areas of the world and the availability of phosphorus to plants and microbes can be strongly affected by soil properties. Even though the phosphorus cycle has been studied extensively, much remains unknown about the key processes governing phosphorus availability in different environments. READ MORE

  5. 5. The Role of the Forest in Climate Policy

    University dissertation from Umeå : Umeå Universitet

    Author : Mathilda Eriksson; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; integrated assessment; forest carbon sequestration; forest bioenergy; avoided deforestation; afforestation; uncertainty; dynamic modeling; DICE; RICE; nationalekonomi; Economics;

    Abstract : AbstractIn Paper [I], I develop the FOR-DICE model to analyze optimal global forest carbon management. The FOR-DICE is a simple framework for assessing the role of the boreal, tropical, and temperate forests as both a source of renewable energy and a resource to sequester and store carbon. READ MORE
