  1. 1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

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

    Författare :Joel Fransson Forsberg; [2023]
    Nyckelord :Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Sammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER

  3. 2. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

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

    Författare :Kristoffer Wilson; [2023]
    Nyckelord :Vibrometer; Biotremology; Imidacloprid; Ants;

    Sammanfattning : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. LÄS MER

  4. 3. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

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

    Författare :Monica Olsson; [2022-10-05]
    Nyckelord :Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Sammanfattning : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. LÄS MER

  5. 4. Effects of Diclofenac on Fish Behavior : A Meta-Analysis

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

    Författare :Patrik Sandström; [2022]
    Nyckelord :activity; behavior; diclofenac; fish; Sweden; aktivitet; beteende; diklofenak; fisk; Sverige;

    Sammanfattning : Pharmaceuticals in aquatic environments have been put under increasing scientific scrutiny as they are frequently found as contaminants in natural waters, often entering via effluent water containing pharmaceutical residue from human excretion. Diclofenac is a frequently found non-steroidal anti-inflammatory drug [NSAID] in waters that has been shown to cause both acute and chronic effects on various aquatic organisms. LÄS MER

  7. 5. Anhörigersättning vid brott

    Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Hannes Grönberg; [2021]
    Nyckelord :Skadeståndsrätt; anhörigersättning; Law and Political Science;

    Sammanfattning : Anhörigersättning är ett skadestånd som i vissa fall betalas ut till personer som tillhör anhörigkretsen till en person som har drabbats av brott eller en i övrigt skadeståndsgrundande handling. Ersättningen syftar till att kompensera de anhöriga för den psykiska chock som händelsen har orsakat dem. LÄS MER
