  1. 1. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Martina Stangl; [2022]
    Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

    Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE

  3. 2. Tillväxtmönster och kvalitet i trädslagsblandade bestånd på höga boniteter : en fallstudie i Snogeholms landskapslaboratorium

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Erik Bergqvist; [2018]
    Keywords : blandskogar; tillväxtmönster; trädslaginteraktioner; virkeskvalitet;

    Abstract : Historiskt har intresset för trädslagsblandningar i Sverige varierat kraftigt och olika positiva fördelar har framhävts under olika tider. På senare tid är den högre artrikedomen i trädslagsblandade bestånd och en möjlighet att delvis bryta granens dominans i södra Sverige ökat intresset för trädslagsblandade bestånd. READ MORE

  4. 3. Klibbalens gödslingseffekt på volymproduktionen i ett blandbestånd av gran och klibbal : en simulering i Heureka

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Therese Andersson; Ronja Jägbrant; [2012]
    Keywords : kväve; kvävefixering; blandskog; blandskogseffekt; Picea abies; Alnus glutinosa; StandWise; biologisk gödsling;

    Abstract : A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. READ MORE

  5. 4. Multiple pesticide stressors and ecosystem functioning in stream detrital food webs

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Mohab Dawoud; [2011]
    Keywords : Stream ecosystem; decomposition process; leaf litter; Lindane; Azoxystrobin; Asellus aquaticus; aquatic microorganism;

    Abstract : Streams and rivers are highly susceptible to environmental degradation from agricultural activities, including the clearance of riparian vegetation and the runoff of chemical fertilizers and pesticides. These impacts are likely to increase in the future as agricultural practices intensify to meet the needs of an expanding human population. READ MORE
