  1. 21. Vad påverkar slaktgrisens renlighet i boxen? : kartläggning av grisens gödslingsbeteende i boxen och hur problemet kan minskas

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Linnéa Andersson; Isabelle Karlsson; [2021]
    Keywords : slaughter pigs; indoor pens; drained floors; fully and partly slatted floors; fouling;

    Abstract : Slaktgrisstallar är vanligtvis byggda för ca 400 djurplatser. Boxarna brukar vara anpassade för 10 – 12 grisar med en slaktvikt på ca 100 kg levandevikt. Boxen där grisarna ska inhysas har ett minimikrav på storlek baserat på svenska Jordbruksverkets författningssamling. READ MORE

  3. 22. Skapa slåtterängar : en jämförande studie om etablering och skötsel

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Emil Wallin; Agnes Hofmann; [2021]
    Keywords : slåtteräng; etablering; pluggplantor; frösådd; äng; urban äng; hö; slåtter; skötsel; Hay meadow; establishment; plug plant; seed sowing; meadow; urban meadow; hay;

    Abstract : Den biologiska mångfalden i vår natur minskar och ängsmarkerna som förr var en stor del av vårt jordbruk har försvunnit till följd av mer effektiva odlingsmetoder. Detta har resulterat i att insekter, vildbin och andra pollinatiörer, som även förser oss människor med mat, försvinner allt snabbare. READ MORE

  4. 23. Post-fire community changes in peatland dwelling beetles : A before-after-control impact study of beetle communities in Swedish mires after a megafire

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Janina Happ; [2021]
    Keywords : Coleoptera; Mires; Peatlands; Wildfire; Forestfire; Megafire;

    Abstract : As a consequence to climate change and resulting severe weather events such as prolonged hot and dry periods, wildfire frequency increases globally. Progressively, these effects are noticeable in high latitude countries such as Sweden where a megafire burned 13 100 ha of managed coniferous forest in 2014. READ MORE

  5. 24. Spatial variation in GHG emissions from drained organic forest soils : implications for Swedish UNFCCC reporting

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna Oskar; [2021]
    Keywords : greenhouse gas; carbon dioxide; methane; nitrous oxide; peat; drainage; ditch; GHG inventory;

    Abstract : Drainage of organic soils for forestry generally increases soil CO2 and N2O emissions but decreases CH4 emissions. Under the United Nations Framework Convention on Climate Change (UNFCCC) countries provide annual national inventories of anthropogenic greenhouse gas (GHG) emissions and removals, which includes emissions of GHGs from drained organic forest soil.

  6. 25. Dynamics of streamflow and stream chemistry in a Swiss pre-Alpine headwater catchment : A fine scale investigation of flow occurrence and electrical conductivity in the temporary streams in the lower Studibach catchment

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elise Baumann; Hanna Berglund; [2021]
    Keywords : Temporary Streams; Pre-Alpine Catchment; Streamflow; Stream Chemistry; Fine Scale Investigation; Electrical-conductivity; Stream Mapping; Temporära bäckar; Pre-Alpina avrinningsområden; Bäckflöden; Vattenkemi; Finskalig undersökning; Elektrisk konduktivitet; Bäck-kartering;

    Abstract : Temporary streams and their dynamics have often been largely overseen in hydrological research and there is relatively little knowledge about how the occurrence of flow in these streams varies temporally and spatially. Temporary streams are important from a hydro- logical perspective because they affect water quantity and quality in downstream peren- nial reaches, and from an ecological perspective because they provide habitat to unique species.
