  2. 11. Adapting Scots pine Regeneration to the Changing Climate : An investigation of the effects of seed coating, arginine addition, and planting position

    Author : Matej Domevscik; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In Sweden, new forest stands have long been artificially regenerated using conifer seedlings. While standardized and widely adopted, this approach may need to be further adapted to the predicted increases in variations in the weather, such as extended periods of drought. READ MORE

  4. 12. Plant ecological studies related to restoration of a degraded ecosystem in central Tanzania

    Author : Shadrack Eliapenda; Ingvar Backéus; Karin Bengtsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Conservation; land degradation; population growth rate; population structure; regeneration; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecological Botany; Ekologisk botanik;

    Abstract : Kondoa Irangi area is among the most degraded ecosystems in Central Tanzania as a result of heavygrazing, fire, collection of fuelwood and improper cultivation practices. The restoration process of thisdegraded ecosystem through natural regeneration is slowed by the semi-arid climate of the area combinedwith poor soil nutrient status. READ MORE

  5. 13. Life Cycle Assessment of Novel Biomethane Systems : energy performance and climate impact

    Abstract : Climate mitigation and supply of renewable energy are global challenges. The main cause of climate change is anthropogenic activities, including consumption of fossil energy sources and land use change. Biomethane, a biomass-derived renewable energy carrier, is interchangeable with fossil-based natural gas and can provide energy services (e.g. READ MORE

  6. 14. Functional ecology of ectomycorrhizal fungi : peroxidases, decomposition, spatial community patterns

    Author : Inga Bödeker; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition. Nitrogen (N) is immobilized in these complex compounds and, thereby, unavailable to the plant community. READ MORE

  7. 15. Effects of Bio-Ash Amendments on the Metabolism of Ectomycorrhizal Fungi : A Method Development and Metabolomic Study

    Abstract : Forest ecosystems have played a fundamental role in the development of our society. Since the beginning of the civilization, forest have provided us with wood as a product for construction, tools, furniture and domestic heating. The well-being of the forest is therefore fundamental to our existence. READ MORE
