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

    Author : Jennie Sandström; Bengt-Gunnar Jonsson; Mattias Edman; Mikael Ohlson; Mittuniversitetet; []
    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. 2. Decadal effects of forest fire on biodiversity and browsing : a comparison between wildfire and prescribed burning

    Author : Emelie Fredriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The role of fire as a natural disturbance in northern European boreal ecosystems has largely disappeared due to effective fire suppression with large consequences for fire-associated biodiversity. Recently, prescribed burns have been introduced as a conservation action that aims to promote biodiversity. READ MORE

  5. 3. Fast Particle Driven Instabilities in Tokamak Plasmas

    Author : Robert Nyqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The burning plasmas of the next generation tokamak fusion experiment ITERwill contain signicant populations of highly energetic ions. Both fusion gener-ated alpha particles and fast ions accelerated by auxiliary heating schemes arecapable of exciting instabilities in the Alfven frequency range, which may inturn cause redistribution of energetic particles and lead to deleterious eventssuch as e.

  6. 4. Functional role of fire-derived charcoal in boreal forest ecosystem processes

    Author : Nathalie Pluchon; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Charcoal is a natural product of wildfires which operate as a major natural disturbance in boreal forested ecosystems. This carbon (C)-rich material is present in most forest soils but its effects on ecosystem processes remain poorly understood. READ MORE

  7. 5. Retention forestry as a conservation measure for boreal forest ground vegetation

    Author : Samuel Johnson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The boreal forest is prone to natural disturbances, especially fire. Despite this, the disturbance caused by forest management is shown to have a severe effect on the system’s biodiversity. READ MORE
