  1. 1. FÖRSÄLJNING AV OCH INSTÄLLNING TILL FRÄMMANDE VÄXTER I TRÄDGÅRDSBRANSCHEN

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

    Författare :Marcus Dalebjörk; [2024-02-12]
    Nyckelord :Invasive alien species; alien plants; horticulture industry; ornamental plants; Sweden; garden owners;

    Sammanfattning : Alien plants that have intentionally been introduced to an area for cultivation in public or private gardens constitute the primary pathway of introduction for invasive alien species that spread into nature. Garden owners want species that have satisfying characteristics, these characteristics are often also linked to plant invasiveness. LÄS MER

  3. 2. Marktäckets och markfuktighetens påverkan på blomsterlupinens (Lupinus polyphyllus) utbredning i Jämtland

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

    Författare :Julia Svedh; [2024]
    Nyckelord :Garden lupine; Lupinus polyphyllus; soil moisture; land cover; invasive alien species; Jämtland; ; Blomsterlupin; Lupinus polyphyllus; marktäcke; markfuktighet; invasiva främmande arter; Jämtland;

    Sammanfattning : Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. LÄS MER

  4. 3. Non-native plants in mountain ecosystems. An exploration of plant diversity and its response to road disturbance and alien invasion.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Anderberg Lina; [2023-10-19]
    Nyckelord :;

    Sammanfattning : Understanding patterns of invasive plants becomes ever more important as anthropogenic presence continues to facilitate their spread. In mountainous landscapes, cases of establishment by nonnative species have become frequent, despite the environmentally unfavorable conditions for plants less adapted to the harsh climate. LÄS MER

  5. 4. Monitoring marine alien and invasive species. A comparison between the traditional method (eRAS) and DNA-based identification of species.

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

    Författare :Josefin Holm; [2023-08-22]
    Nyckelord :;

    Sammanfattning : There is a major concern with the uncontrolled spreading of alien and invasive species, caused by an increase in travelling by boat globally. These are dispersed via ballast water, by fouling on ships and in fishing gear. LÄS MER

  7. 5. The use of regurgitated pellets from the great cormorant to detect the presence of the round goby

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

    Författare :Tim Dorup; [2023-08-07]
    Nyckelord :Invasive species; Regurgitated pellets; Great cormorant; Round goby; dPCR;

    Sammanfattning : The round goby (Neogobius melanostomus) is an invasive alien species that poses one of the greatest threats to biodiversity and ecosystem services in Sweden today. The round goby originates from the Black Sea and Caspian Sea but has in recent decades rapidly spread with global shipping traffic to new areas in Europe and North America. LÄS MER
