  1. 1. Råmjölkskvalité hos sugga – inverkan på smågrisdödlighet och tillväxt

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Elin Skans; [2023]
    Nyckelord :råmjölk; råmjölkskvalité; IgG; smågrisdödlighet; tillväxt; Brix refraktometer;

    Sammanfattning : Sverige har hög smågrisdödlighet jämfört med andra länder. Mycket forskning har gjorts inom området men siffran är fortsatt hög. I dagsläget saknas det studier på hur suggans råmjölkskvalité påverkar smågrisarnas tillväxt och överlevnad. LÄS MER

  3. 2. Research of alternative methods of marine litter collection : Study of marine plastic pollution

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ciaran Conway; Aydar Gaynullin; [2022]
    Nyckelord :;

    Sammanfattning : The discovery of plastic and its unique qualities created a great opportunity for manufacturing and an improved quality of life. The annual production of plastic is 368 million tonnes, this number is continuously increasing as nowadays almost every product has a plastic component in it. However, this improvement in lifestyle comes at a cost. LÄS MER

  4. 3. Jämförelse av digivningsbeteende hos korsningssuggor : en pilotstudie

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Nellie Rosenwall; [2022]
    Nyckelord :Sugga; raskorsning; digivningsfrekvens; digivningslängd; beteende;

    Sammanfattning : Differences in breeding goals in pig production have led to maternal breeds have a higher selection pressure on reproductive traits and paternal breeds have been focused on meat quality. In maternal breeds, this has led to an increase in the number of born piglets, but this is not something that all farmers desire as this put pressure on both the sow and the farmer. LÄS MER

  5. 4. Ground-nesting bees in the age of urbanization : quality of sandy habitat and wild bee diversity in Uppsala, Sweden

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Indre Cepukaite; [2022]
    Nyckelord :ground-nesting bees; wild bees; cleptoparasitic bees; indicator taxon; urbanization; sandy soil; bare soil; habitat age; ground cover; diversity; pollinator protection and conservation;

    Sammanfattning : Wild bees are indispensable pollinators of most flowering plants and agricultural crops, and thus are vital components of functioning ecosystems and provide essential ecosystem services to humans. This study primarily aimed to discover the environmental features of nesting habitat that are mostly associated with wild ground-nesting and associated cleptoparasitic bee species diversity in urban landscape.

  7. 5. Reindeer decrease soil carbon stocks and deplete labile soil carbon

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Josua Seitz; [2022]
    Nyckelord :Reindeer; SOC; soils; Finnland; 13C NMR;

    Sammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.
