  1. 1. Blomsterlupin versus tre inhemska ärtväxtarter : Jämförelser av besöksfrekvens och pollineringseffektivitet hos olika grupper av insektspollinatörer

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

    Författare :Tobias Westling; [2023]
    Nyckelord :L. polyphyllus; L. palustris; V. cracca; T. pratense; pollinators; visitation frequency;

    Sammanfattning : Red clover (Trifolium pratense) is currently used as a green fertilizer for agriculture in northern Sweden. However, due to its low resistance against diseases and a minimal benefit to local pollinators, there is a need to find alternative native species that maximize the benefits for pollinators and agriculture.

  4. 3. Flowering phenology, pollination and seeding interactions in Garden Lupine (Lupinus polyphyllus)

    Kandidat-uppsats, Karlstads universitet

    Författare :Amanda Boström; [2020]
    Nyckelord :pollination; Garden Lupine; bumblebee; Bombus; Lupinus polyphyllus; self-pollination; pollinering; blomsterlupin; humlor; Bombus; Lupinus polyphyllus; självpollinering;

    Sammanfattning : The spreading of the invasive plant Garden Lupine (Lupinus polyphyllus) has become a matter of national importance in Sweden, due to it posing a threat to native plant and pollinator diversity. The effective attraction of bumblebees (Bombus spp. LÄS MER

  5. 4. A Search for Neonicotinoid Binding Sites in the Optic Lobes of Honeybees and Blowflies

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Ashley Hulcoop; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes.

  7. 5. Urban gardens found to have higher pollination success than rural gardens

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Lisa Bredenberg; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Recent decline in wild pollinators have been reported and studies have found a connection to increasing urbanisation, larger homogenous landscapes and increased pesticide usage. The pollinators are important to preserve for various ecosystem services, such as plant reproduction, however the effects on pollination success has not been thoroughly studied in relation to urbanisation.
