  1. 1. Hur kan dammar påverka den urbana biologiska mångfalden?

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Saga Forsberg; [2024]
    Nyckelord :biologisk mångfald; biodiversitet; öppna vatten; dagvattenlösning; urban; ekosystem; ekosystemtjänster; grön-blå infrastruktur; arter; klimatförändringar;

    Sammanfattning : Denna litteraturstudie sammanställer forskningsresultat från andra studier. Det finns många faktorer som påverkar urban biologisk mångfald, som exempelvis vattenföroreningar, övergödning, urban heat island effekten, förekomsten av invasiva arter, angränsande landskapstyp, val av skötsel och utformning av dammen.

  3. 2. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Carl-Johan Dekker; [2023-08-07]
    Nyckelord :Invasive alien species; management; nature conservation; biodiversity;

    Sammanfattning : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. LÄS MER

  4. 3. Assessment of the invasive Himalayan balsam (Impatiens glandulifera) distribution in Sweden : The effects of latitudinal location and land cover on the distribution

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Daniel Penttinen; [2023]
    Nyckelord :Himalayan balsam; Impatiens glandulifera; distribution; Jättebalsamin; Impatiens glandulifera; utbredning;

    Sammanfattning : Invasive alien species are recognized as a major problem worldwide. They affect native flora and fauna negatively, resulting in loss of biodiversity and increased economic costs of the species’ themselves and management efforts. LÄS MER

  5. 4. Thermal tolerance of native vs. invasive marine species at the Northern coast of Portugal

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sofie Michelsen; [2023]
    Nyckelord :Biodiversity; Climate change; Marine ecosystems; Marine heat waves; Intertidal environment; Invasive species; Macroalgae; Mussels; Sustainable Development; Thermal tolerance;

    Sammanfattning : Two prominent factors posing a major threat to biodiversity in marine ecosystems are climate change and the establishment of invasive species, and the interaction between these two. Because of the upwelling of cold, nutrient-rich water, the coast of Portugal is a thermal refuge and distribution edge for cold-adapted species, making it a particularly important study area from a biodiversity point of view.

  7. 5. 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
