  1. 21. Mussels in deep water with climate change: Spatial distribution of mussel (Mytilus galloprovincialis) growth offshore in the French Mediterranean with respect to climate change scenario RCP 8.5 Long Term and Integrated Multi-Trophic Aquaculture (IMTA) using Dynamic Energy Budget (DEB) modelling

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Victoria Persson; [2022]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Mediterranean; Mytilus galloprovincialis; Dynamic Energy Budget; DEB; growth rate; France; mussel cultivation; mussel farming; offshore; aquaculture; climate change; Integrated Multi-Trophic Aquaculture; IMTA; Earth and Environmental Sciences;

    Sammanfattning : Victoria Persson Abstract Mussel cultivation is a sustainable type of food production that may help mitigate the nutritional needs of a future world population of 10-12 billion in 2100. The demand for mussels on the French market is increasing but the production is saturated due to a lack of space for expanding the cultivation close to shore. LÄS MER

  3. 22. Azithromycin effects on R. subcapitata on molecular levels : Ecotoxicological study on the effects of a pollutant on chlorophyll contents, pcna and cyt P450 genes expression

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Alaa Alsayed Ahmad; [2022]
    Nyckelord :;

    Sammanfattning : Antibiotics are considered a type of antimicrobial that particularly has an impact on bacteria or fungi in humans and animals. The widespread use of common antibiotics, combined with the fact that the majority of active antibiotics and their metabolites are water-soluble, results in persistent pollution in aquatic environments, as well as a potential threat to ecosystems.

  4. 23. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Nanna Walther; [2022]
    Nyckelord :Environmental toxicology; Symbiodiniaceae; miljötoxikologi; phytoplankton; UV-filter chemicals; corals; environmental biology; biology; toxicology; chemicals; sunscreen; pollution; ocean; coral bleaching;

    Sammanfattning : Coral bleaching causes the disappearance of unique ecosystems supporting thousands of different species. The corals health depends on its relationship with its endosymbiont, the zooxanthellate Symbiodiniaceae. This mutualistic relationship can be disrupted by anthropogenic chemical pollution by inducing physiologically stress in Symbiodiniaceae. LÄS MER

  5. 24. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abigail Huertas Herrera; [2021]
    Nyckelord :Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Sammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  7. 25. Design and implementation of embedded system for chl-a fluorescence detection

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anargyros Katsogridakis; [2021]
    Nyckelord :Embedded systems; Microcontrollers; Harmful algal bloom; Climate change; chl-a fluorescence; Inbyggda system; mikrokontroller; skadlig algblomning; klimatförändring; chl-a-fluorescens;

    Sammanfattning : Over the last decades, the effects of climate change have become increasingly evident across natural environments. Apart from other areas, climate change poses a serious threat on water quality. LÄS MER
