  1. 16. Modelling the effects of substituting pollinators in decline

    Kandidat-uppsats, Lunds universitet/Matematik LTH

    Författare :Axel Eriksson; [2023]
    Nyckelord :pollinators; plants; mutualism; competition; equilibrium populations; Mathematics and Statistics;

    Sammanfattning : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. LÄS MER

  3. 17. The effect of life history and weather on onset of flowering and length of flowering period of agricultural weeds

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Amanda Karpaty Wickbom; [2023]
    Nyckelord :global warming; agricultural weeds; first flowering; flowering phenology;

    Sammanfattning : With a warming climate and the usage of monocultures in food production it is possible we may face more issues concerning food insecurity in the future as pollinators struggle to find food in agricultural landscapes. Therefore, it is of value to know whether common agricultural weeds are important sources of food for pollinators. LÄS MER

  4. 18. Pollinator communities on a landscape complexity gradient in southern Sweden

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Hanna Olsson; [2023]
    Nyckelord :pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

    Sammanfattning : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. LÄS MER

  5. 19. Italian winegrowers’ acceptance of results-based agri-environmental schemes

    Master-uppsats, SLU/Dept. of Economics

    Författare :Margherita Muzzillo; [2023]
    Nyckelord :outcome-based agri-environmental schemes; Italy; contingent valuation method; common agricultural policy;

    Sammanfattning : As the debate around the cost-effectiveness of outcome-based agri-environmental schemes (AES) is growing at the European level, the potential of the payment-by-results system is currently being explored by researchers and policymakers. These payment schemes have many benefits. LÄS MER

  7. 20. Hur skapas en trädgård som gynnar biologisk mångfald som samtidigt kräver en låg skötselinsats? : med Skurups kommun som exempel

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Mariette Mattisson; [2023]
    Nyckelord :biologisk mångfald; biological diversity; garden; villaträdgård; trädgårdsideal; low maintanence; plants for pollinators; ecological gardening; växter; uppskattas av pollinerare;

    Sammanfattning : Människans framfart och utbredning tränger undan naturen allt mer, vilket främst beror på det skogs- och jordbruk som råder idag. Som en följd av detta minskar den biologiska mångfalden, vilket gör att flera djurarter även minskar i antal. Det är insekterna som minskar snabbast på flera ställen i världen. LÄS MER
