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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Josefin Holm; [2023-08-22]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Hur mår Östhammarsfjärden? : vårblomning som möjlig indikator på vattenkvalitet

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Freja Westermark; [2023]
    Keywords : Vattenkvalitet; bioindikator; plankton; kväve; fosfor; närsalter; Östhammar;

    Abstract : Denna uppsats undersöker vattenkvaliteten i Östhammarsfjärdarna med fokus på näring och algblomning. Provtagning utfördes för att undersöka om planktonanalyser gav samma resultat som fysikalisk-kemiska analyser. READ MORE

  4. 3. Ecological impacts of dam removal in Swedish inland waters : Effects on water chemistry and fish demography

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Johanna Ekman; [2023]
    Keywords : biology; ecology; dam removal; Sweden; impact; inland waters; ecosystem; water chemistry; fish demography; Perca fluviatilis; European perch; biologi; ekologi; dammutrivning; Sverige; påverkan; inlandsvatten; ekosystem; vattenkemi; fiskdemografi; Perca fluviatilis; abborre;

    Abstract : Dams play an important role in our society, but their negative impacts on aquatic ecosystems have led to a need for conservation efforts to mitigate the negative effects. In some instances, dam removal has been suggested to be the most economically and ecologically beneficial restoration method to improve longitudinal connectivity. READ MORE

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

    University essay from KTH/Industriell bioteknologi

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

    Abstract : 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. READ MORE

  6. 5. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. READ MORE
