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

    University essay from Karlstads universitet

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

    Abstract : 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. READ MORE

  3. 2. A Search for Neonicotinoid Binding Sites in the Optic Lobes of Honeybees and Blowflies

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Ashley Hulcoop; [2019]
    Keywords : Biology and Life Sciences;

    Abstract : 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.

  4. 3. Urban gardens found to have higher pollination success than rural gardens

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Lisa Bredenberg; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : 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.

  5. 4. Effects of leaf beetle herbivory on pollination success and fruit development in woodland strawberry Fragaria vesca

    University essay from SLU/Dept. of Ecology

    Author : Lisa Malm; [2013]
    Keywords : herbivory; pollination success; pollinator reference; fruit development; fruit yield; leaf beetles; Galerucella tenella; Galerucella sagittariae; Fragaria vesca;

    Abstract : Cultivating well-developed and marketable garden strawberries (Fragria x ananassa) and woodland strawberries (Fragaria vesca) depends on successful pollination by insects. Organic garden strawberry plantations harbour higher pollinator densities and have been shown to produce bigger and better developed fruits than conventional farms. READ MORE

  6. 5. Herbivores, pollinators and selection on flowering time in tetraploid and octoploid Cardamine pratensis

    University essay from Stockholms universitet/Institutionen för ekologi, miljö och botanik

    Author : Elsa Fogelström; [2013]
    Keywords : Cardamine; herbivory; herbivore mediated selection; pollination; pollen limitation; polyploidy; selection; flowering phenology;

    Abstract : Repeated polyploidization events are thought to be among the most important causes of sympatric speciation throughout evolutionary time. Changes in phenology and trait expressions that arise in polyploids have been shown to affect plant interactions with insect herbivores and pollinators. READ MORE
