  2. 1. Environmental protection in Swedish forestry : a study of the implementation process

    Author : Katarina Eckerberg; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; clear felling; environmental policy; forest policy; Forestry Act; implementation analysis; nature conservation; public participation;

    Abstract : According to the Swedish Forestry Act, environmental protection is required within forest operations regardless of forest ownership. This thesis examines the extent to which regulations issued by the National Board of Forestry are implemented in clearcuttings. READ MORE

  4. 2. Brazilian public protection regulations and the preservation of ecosystem services and biodiversity

    Author : Flavio L. M. Freitas; Ulla Mörtberg; Jan Börner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; Native vegetation; forest conservation; Brazilian Forest Act; Protected areas; Ecosystem services; Biodiversity; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Brazil is significant for sustaining ecosystems services and biodiversity of global importance. However, the expansion of forestry and agriculture to supply national and international markets often results in loss of ecosystem services and biodiversity. Public protection regulations play a crucial role in setting limits for agricultural expansion. READ MORE

  5. 3. Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures

    Author : Emma Fältström; Stefan Anderberg; Annica Carlsson; Hamse Kjerstadius; Lian Lundy; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Municipalities; Plastic; Pollutants; Preventive measures; Stormwater; Wastewater; Water treatment;

    Abstract : Water pollution has long been considered a challenge in urban areas. Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters. Microplastics are a pollution problem of growing concern. READ MORE

  6. 4. Internal oxygen transport to below-ground parts: importance for emergent macrophytes

    Author : Viveka Vretare Strand; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; water depth; zonation; phenotypic plasticity; biomass allocation; pressurised ventilation; oxygen; Phragmites australis; emergent macrophytes; common reed; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

    Abstract : This thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. READ MORE

  7. 5. The role of benthic macrofauna in nitrogen cycling in eutrophic lake sediment

    Author : Jonas Martin Svensson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen retention; nitrous oxide; oligochaetes; chironomids; mineralisation; nitrification; denitrification; eutrophic; sediment; lake; Macrofauna; nitrogen cycling; fish reduction.; Ecology; Ekologi;

    Abstract : This thesis concerns the role of sediment-living macrobenthos in the cycling of nitrogen species and nitrogen transformation in eutrophic freshwater sediments. In my thesis I have, employing 15N-isotope techniques in laboratory experiments, shown the importance of infaunal chironomid larvae and oligochaetes on denitrification in eutrophic lake sediments.
