  2. 6. On the contribution of forest bioenergy to climate change mitigation

    Author : Olivia Cintas Sanchez; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL 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

  4. 7. 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 : NATURVETENSKAP; NATURAL SCIENCES; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; Biology; Biologi; Biology; Biologi;

    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).

  5. 8. Forest edge development : management and design of forest edges in infrastructure and urban environments

    Author : Björn Wiström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis investigates design guidelines and management systems for the development of stationary forest edges with a graded profile in infrastructure and urban environments. The spatial restriction for the edge to move forward caused by human land use counteracts the natural dynamics and development patterns of graded forest edges. READ MORE

  6. 9. Development of economic forest tree breeding objectives

    Author : Mats Berlin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The overall objective of this thesis was to suggest a framework for developing forest tree breeding objectives with particular emphasis on boreal conditions and, as components of this framework, to define breeding objectives and calculate economic weights based on two case studies of Scots pine in northern Sweden. The framework was designed to take into account boreal conditions, with long rotations, heterogeneous raw materials and a diverse production system. READ MORE

  7. 10. 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 : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL 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
