  1. 1. Arbete med biologisk mångfald på Kungliga Djurgården : med fokus på rödlistade och invasiva arter

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Vanda Barkstedt; [2023]
    Nyckelord :biologisk mångfald; rödlistade arter; invasiva arter; skötselåtgärder; bekämpningsåtgärder; Kungliga Djurgården; Kungliga Djurgårdens förvaltning;

    Sammanfattning : Fler och fler arter hotas av förändrad markanvändning, klimatförändringar, spridning av invasiva arter m.m. För att motverka den negativa utvecklingen har urbana grönområden blivit allt viktigare. LÄS MER

  3. 2. Constructing a food web from inventory data in a boreal forest-dominated national park in south-eastern Sweden

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Philip Kjellström; [2023]
    Nyckelord :ecological network; food web; boreal forest food web; national park food web; interspecific competition; swedish forest; construction food web;

    Sammanfattning : A food web was constructed for a boreal-forest dominated national park in south-eastern Sweden, called Tyresta national park and its surrounding nature reserve. Due to increasing threats to mammalian species and their critical role in the food web mammals were used as the outset of the food web, and from there branching out to taxa trophically interacting with mammals directly and indirectly.

  4. 3. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ida Widegren; [2023]
    Nyckelord :Plagionotus detritus; P. detritus; Cerambycidae; Cerambycinae; longhorn beetle; insects; habitat; oak; Quercus; conservation; ecology; endangered; threatened;

    Sammanfattning : The longhorn beetle Plagionotus detritus is associated with newly dead oak wood and is declining throughout its distribution range. In Sweden, P.detritus has displayed one of the most dramatic reductions in distribution recorded for insect species and is near regional extinction. LÄS MER

  5. 4. Effects of temperature and microplastic concentration on the consumption of microplastic particles by the detritivore Asellus aquaticus

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Yasmin Screech; [2023]
    Nyckelord :Microplastic; Asellus aquaticus; concentration; temperature; faecal pellets;

    Sammanfattning : Microplastic (MP) pollution has now reached a point where particles can be found in every environmental compartment across the globe. However, the ecological and long-term consequences of MPs are largely unknown. LÄS MER

  7. 5. Recent expansion of the endangered beetle Plagionotus detritus in the greater Stockholm area

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Elin Lönnberg; [2023]
    Nyckelord :;

    Sammanfattning : Biodiversity is declining worldwide, and the biggest reason for this is habitat destruction. In Sweden one third of all the red listed species belongs in broadleaved deciduous forests. The  most common reason for the endangerment of these species is the destruction of the deciduous forest.
