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

    University essay from SLU/Dept. of Ecology

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

    Abstract : 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.

  3. 12. Complete removal of biomass from oilseed radish as a cover crop decreased nitrous oxide emissions

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

    Author : Emma Lövgren; [2022]
    Keywords : Nitrous oxide; cover crops; freeze-thaw cycles; immobilization; oil seed radish;

    Abstract : One of the many benefits of utilizing cover crops in crop rotations is their carbon sequestrating effect. However, frost-sensitive cover crops could emit high levels of the potent greenhouse gas nitrous oxide. READ MORE

  4. 13. Cover crops for plant protection : Cover crops for control of root pathogenic Plasmodiophora brassicae and the root parasitic nematodes Pratylenchus penetransand Meloidogyne hapla

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Izabella Lundborg; [2022]
    Keywords : Clubroot disease; plant parasitic nematodes; Lupinus angustifolius; Avena strigosa; Phacelia tanacetifolia; Lolium perenne; Solanum lycopersicum; Brassica napus;

    Abstract : Root pathogens and parasites are an increasing problem in agricultural and horticultural production. The soil borne pathogen Plasmodiophora brassicae is one of the major pathogens in oilseed rape production and the plant parasitic nematodes (PPNs), Pratylenchus penetrans and Meloidogyne hapla infest important crops such as carrot, potato and strawberry.

  5. 14. Utvintrande mellangrödor i höstraps : effekt på raps, ogräs och skadegörare

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Jakob Larsson; [2021]
    Keywords : Brassica napus; kompanjongrödor; insådd; ekologisk odling; avkastning;

    Abstract : Höstraps är en viktig avbrottsgröda i spannmålsdominerande växtföljder, och odlingen av höstraps har ökat i Sverige de senaste tjugo åren. Rapsen är normalt utsatt för ett högt tryck från ogräs och skadegörare, vilket gör att odling av ekologisk höstraps är ytterst begränsad. READ MORE

  6. 15. Intercropping oats with annual clovers : effects on yields and aspects of biodiversity

    University essay from SLU/Dept. of Ecology

    Author : Anna Douhan Sundahl; [2021]
    Keywords : intercropping; cover cropping; pollinators; natural predators; weeds; clover; oats;

    Abstract : The use of fertilizers, pesticides and herbicides has contributed to greatly increase the crop yields per hectare. Humanity has become reliant on artificial inputs overshadowing usage of resources from ecosystem services that we continue to weaken further, by using agricultural practises decreasing landscape and species diversity.
