  1. 6. TIME FOR SHIFT CHANGE IN THE FABRIC OF EXISTENCE Exploring the role of darkness and artificial light for humans and biodiversity

    University essay from Göteborgs universitet / Institutionen för ekonomi och samhälle

    Author : Maya Strömgren; [2021-06-23]
    Keywords : Darkness; artificial light; light pollution; biodiversity; human- non-human relations; all-ecology; non-representational theory; Mörker; artificiellt ljus; ljusföroreningar; biodiversitet; människa-natur relationer; all-ekologi; non-representational theory;

    Abstract : Den här uppsatsen tar avstamp i förlusten av biologisk mångfald, och då specifik förlusten av biologisk mångfald på grund av överflödigt artificiellt ljus under dygnets mörka timmar, även kallat ljusföroreningar. Den daglevande människan har utvidgat sina timmar från de naturligt ljusa till att inkludera dygnets alla timmar, vilket resulterat i minskat handlingsutrymme för den nattlevande flora och fauna.

  3. 7. Flower-visiting insects benefit from forest in the surrounding landscape

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

    Author : Emilia Sundell; [2021]
    Keywords : Apoidea; clear-cut; Coleoptera; forest; Hymenoptera; landscape composition; Lepidoptera; Syrphoidea;

    Abstract : Habitat loss and fragmentation due to agricultural practices are causing worrying declines in insect diversity and biomass. Agricultural intensification, among other things, have led to a decline in semi-natural grasslands. Forest in the surrounding landscape can have a positive effect on species abundance in grasslands.

  4. 8. Impact of different light sources on the responses of moth

    University essay from Högskolan i Halmstad

    Author : Yanhe Zhou; [2021]
    Keywords : Artificial light at night ALAN ; Greater wax moth; Light Attraction; light emitting diodes; LED; Galleria mellonella;

    Abstract : In recent decades, the negative effects of artificial light at night on natural ecosystems have attracted the attention of ecologists. Studies have shown that artificial light at night leads to a considerable reduction in insects and has a worrying impact on terrestrial ecosystems, including nocturnal insects (e.g. Lepidoptera) such as moths.

  5. 9. 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

  6. 10. Nocturnal moths use of novel habitats : a case study on a power line in a forest-mire mosaic in boreal Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Oskar Lövbom; [2020]
    Keywords : pollinators; Lepidoptera; moth; transmission line; assemblage structure; Noctuoidea; Geometridae;

    Abstract : Biodiversity and pollinators are declining all over the world, and a factor thought to cause this decline is destruction of natural habitats. One new way that has been discussed in an effort to try to mitigate the effects of declining habitats is to understand and use novel habitats, which are habitats created when, for example, building roads, railways, and power lines.
