  1. 1. Interactions between climate, natural disturbances, and regeneration in boreal and hemi-boreal forests

    Författare :Igor Drobyshev; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conservation strategies; Plant ecology; Växtekologi; taiga; seasonal climate; shoot increment; larch; reconstruction; human; canopy gap; fire history; boreal; natural disturbances; dendrochronology;

    Sammanfattning : Natural disturbance is an important driving force of community dynamics in many forest types around the globe. Understanding spatial and temporal properties of disturbance events in the present and in the past is important in formulating the nature conservation strategies as well as for the modeling of climate and human impacts on forest vegetation.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

    Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER

  5. 4. A land of one's own : Sami resource use in Sweden's boreal landscape under autonomous governance

    Författare :Gudrun Norstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; HUMANIORA; HUMANITIES; ALS; archaeology; boreal forest; dendrochronology; forest history; historical maps; interdisciplinary research; lidar; Sami; settlement patterns; ALS; arkeologi; boreal skog; bosättningsmönster; dendrokronologi; historiska kartor; lidar; samer; skogshistoria; tvärvetenskap;

    Sammanfattning : The Sami dominated large parts of boreal Sweden well into the 18th century, and knowledge of Sami subsistence patterns is therefore a key to the region’s forest history. Although much research has been done on Sami resource use and landscape impact, the context is often vaguely understood. LÄS MER

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

    Författare :Jennie Sandström; Bengt-Gunnar Jonsson; Mattias Edman; Mikael Ohlson; Mittuniversitetet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
