  1. 1. The Potential to Target Smaller Sized Baltic Herring to Decrease the Dietary Exposure - an Assessment Based on Dioxin Samples from the Southern Baltic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Sofie Gustafsson; [2024]
    Nyckelord :Dioxin; PCDD Fs; dl-PCBs; Herring; Baltic; Fishery; Technology and Engineering;

    Sammanfattning : PCDD/Fs and dl-PCBs, or more commonly referred to as dioxin and dioxin like substances are compounds present in our surrounding environment. As some congeners of these have been shown to be toxic, they are regulated under the Stockholm Convention. LÄS MER

  3. 2. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

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

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER

  4. 3. A Comprehensive Review of the Factors Influencing the Environmental Impact of different Species bred in Closed Land-based Recirculating Aquaculture Systems

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Siri Samuelsson; [2022]
    Nyckelord :Recirculating aquaculture system; renewable electricity; Feed Conversion Ratio; environmental impact; freshwater eutrophication; climate change; land use; cumulative energy use; acidification; Earth and Environmental Sciences;

    Sammanfattning : Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). LÄS MER

  5. 4. Undersökning av epifytiska lavar i stadsmiljö : En jämförelse mellan Uddevalla och Östersund

    Kandidat-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Moa Karlsson; [2021]
    Nyckelord :biologisk mångfald; urbana områden; epifytiska lavar; övervakning; biodiversity; urban areas; epiphytic lichen; monitoring;

    Sammanfattning : Biologisk mångfald har en nyckelroll i välfungerande ekosystem och bevarandet av denna även i stadsmiljö blir väsentligt med tanke på den ökande urbaniseringen. Övervakning av olika slag kan ses som ett steg på vägen till ökad kunskap inom ämnet om hur den biologiska mångfalden skall skötas och stödjas. LÄS MER

  7. 5. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Giulia Elli; [2019]
    Nyckelord :PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Sammanfattning : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. LÄS MER
