  1. 11. Förhållanden för pollination i rödklöver; konstant eller tidsbunden variation? : undersökning av tidpunktens inflytande över variation i pollinering och frösättning hos Trifolium pratense L.

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Helena Carlsson; [2023]
    Keywords : Rödklöver; Trifolium pratense; pollination; frösättning; Bombus;

    Abstract : Frösättning i klöver (Trifolium pratense L.) är i majoritet av moderna kommersiellt odlade sorter högt varierande och ger en opålitlig och osäker produktion. READ MORE

  3. 12. Modelling the effects of substituting pollinators in decline

    University essay from Lunds universitet/Matematik LTH

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

    Abstract : 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. READ MORE

  4. 13. The effect of life history and weather on onset of flowering and length of flowering period of agricultural weeds

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Amanda Karpaty Wickbom; [2023]
    Keywords : global warming; agricultural weeds; first flowering; flowering phenology;

    Abstract : 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. READ MORE

  5. 14. Pollinator communities on a landscape complexity gradient in southern Sweden

    University essay from SLU/Dept. of Ecology

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

    Abstract : 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. READ MORE

  6. 15. Italian winegrowers’ acceptance of results-based agri-environmental schemes

    University essay from SLU/Dept. of Economics

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

    Abstract : 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. READ MORE
