  1. 6. Inte bara en bisyssla : och multifunktionella skyddszoners roll för pollinatörers förekomst i åkermark

    University essay from SLU/Dept. of Ecology

    Author : Elsa Rozenbeek; [2021]
    Keywords : pollinatörer; pollinering; skyddszoner; blomsterremsor; biologisk mångfald; Samzoner;

    Abstract : Efterfrågan på pollinerade produkter från jordbruket ökar i takt med jordens befolkning. Samtidigt hotas pollinatörers existens av mänsklig omvandling av deras livsmiljöer och ett varmare klimat. READ MORE

  3. 7. The natural pest control potential of different landscapes : mapping the ecosystem service in three regions of Sweden

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

    Author : Charlotte Peitz; [2021]
    Keywords : natural pest control; natural enemies; landscapes; agricultural diversification; pesticide reduction; mapping; ecosystem service; ecological intensification; agroecology;

    Abstract : Natural pest control describes the process of natural enemies suppressing pests and thus reducing crop damage and stabilizing yields. How well these beneficial arthropod predators and parasitoids can thrive in a landscape is influenced by the land-use types in the vicinity, such as forest patches, pastures, or agricultural fields, and their ability to provide resources.

  4. 8. The effect of restoration of semi-natural grassland on arthropod populations

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

    Author : Molly Wikingson; [2021]
    Keywords : Arthropoda; Conservation; Grasslands; Landscape factors; Restoration success; Species rich communities;

    Abstract : Semi-natural grasslands are valuable ecosystems that have a high biodiversity. Unfortunately, a lot of this biodiversity is being lost as semi-natural grasslands are declining in both size and number. Restoration to reestablish semi-natural grasslands is often done by removing shrubs and trees and planting seeds. READ MORE

  5. 9. Insect pollination of faba beans, Vicia faba : the abundance and foraging behaviour of different pollinators and their effect on crop yield

    University essay from SLU/Dept. of Ecology

    Author : Ylva Johansson; [2020]
    Keywords : honeybee; Apis mellifera; bumblebees; B. pascuorum; B. hortorum; B. lucorum; B. terrestris; B. ruderatus; B. cryptarum; B. distinguendus; B. lapidarius;

    Abstract : Faba beans, Vicia faba is known as a self-pollinating crop, however significant yield increases have been found in plants visited by honeybees and bumblebees. The bees either make positive visits, entering the flower and transferring pollen between different flowers resulting in cross-pollination, or negative visits, piercing the flower to “steal” nectar or collect nectar from extrafloral nectaries.

  6. 10. Bumblebee resource dynamics : a review of foraging and nesting in the agricultural landscape

    University essay from SLU/Dept. of Ecology

    Author : Anna Douhan Sundahl; [2020]
    Keywords : bumblebees; bumblebee population dynamics; bumblebee drivers; flower strips; competition with honeybees; foraging; nesting; hibernation;

    Abstract : 90 % of all plants on earth either benefits or entirely depends on pollination. There are pollinators among families of bees (Apidea), butterflies (Lepidoptera) and birds (Aves). Bees of genus Bombus spp., bumblebees, are especially important and provide pollination service for 80 % of the crops of Europe and many wild plant species. READ MORE
