  2. 1. Forest water governance : challenges in cross-sectoral and multi-level collaboration

    Author : Irina Mancheva; Katarina Eckerberg; Anna Zachrisson; Susan Baker; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Forest water; Governance; Cross-sectoral governance; Multi-level governance; Governance mode; Collaborative governance; Natural resource management; Environmental policy; Water Framework Directive;

    Abstract : Forests and water are highly interconnected with forestry practices negatively affecting forest water. In the last five decades, the Swedish state has enacted multiple policy changes and allocated significant resources towards the implementation of soft policy instruments to alleviate the effects on forest water.

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 3. On the contribution of forest bioenergy to climate change mitigation

    Author : Olivia Cintas Sanchez; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Forest bioenergy; forest management; climate change; energy systems.; GHG balances; forest supply; carbon budget;

    Abstract : Greenhouse gas (GHG) emissions have to be drastically reduced to keep global warming below 2 degrees. Bioenergy can play a role in climate change mitigation by substituting for fossil fuels. READ MORE

  6. 4. Forest-stream linkages : Experimental studies of foraging and growth of brown trout (Salmo trutta L)

    Author : Pär Gustafsson; Eva Bergman; Larry Greenberg; John Armstrong; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; Biology; Biologi; Biology; Biologi; functional response; foraging;

    Abstract : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

  7. 5. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing

    Author : Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Stefano Manzoni; Udita Sanga; Vivian Ribeiro; Stockholms universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Environmental Sciences; miljövetenskap; Ecology and Evolution; ekologi och evolution; Hydrology; hydrologi;

    Abstract : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. READ MORE
