  2. 1. Establishment, Growth and Population Dynamics in two Mosses of Old-growth Forests

    Author : Karin Wiklund; Håkan Rydin; Staffan Karlsson; Lloyd Stark; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Buxbaumia viridis; Neckera pennata; bryophyte; pH; phosphorus; water potential; precipitation; metapopulation; environmental stochasticity; ecology; plant; Biologi; Biology; Biologi;

    Abstract : Biodiversity in forests depends on long canopy continuity and existence of different elements which function as substrates for varying organisms. Bryophytes often occupy specific substrates with a patchy distribution. READ MORE

  5. 3. 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

  6. 4. Effects of drought on boreal forest understory species

    Author : Irena A. Koelemeijer; Kristoffer Hylander; Johan Asplund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity conservation; boreal forests; bryophytes; canopy cover; climate change; drought; extreme climatic events; forest management; forest understory; fungi; lichens; plants; rainout shelter; soil communities; soil moisture; transplant experiment; Ecology and Evolution; ekologi och evolution;

    Abstract : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.

  7. 5. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration

    Author : Geraldine Derroire; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. READ MORE
