  1. 1. 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

  3. 2. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

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

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  4. 3. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Philippe Simon; [2023]
    Nyckelord :Ley production; Nitrogen fixation; Pollination ecology;

    Sammanfattning : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). LÄS MER

  5. 4. Machine learning-assisted image analysis and metabarcoding for monitoring of plankton in the seas surrounding Sweden

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Karin Garefelt; [2023]
    Nyckelord :Imaging FlowCytobot; imaging-in-flow cytometry; plankton imaging; convolutional neural network; metabarcoding; Imaging FlowCytobot; flödesmikroskopi; övervakning av plankton; konvolutionella neuronnät; DNA-streckkodning;

    Sammanfattning : I miljöövervakningen av haven runt Sverige har manuell mikroskopi av plankton länge varit den huvudsakliga tekniken för att övervaka växtplanktonbestånden och algblomningar. Nya tekniker utvärderas, men det är inte känt hur resultaten från de nyare teknikerna relaterar till varandra. LÄS MER

  7. 5. Pollen identification using sequencing techniques

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Bimaljeet Kaur; [2022]
    Nyckelord :pollen; rbcL gene; barcoding; metabarcoding; Sanger sequencing; MinION sequencing;

    Sammanfattning : Palynology or the study of pollen, is essential understand the relationship between plants and their pollinators. Traditionally, pollen grains are identified by microscopy. The method has several shortcomings, such as being time-consuming and having low taxonomic resolution. LÄS MER
