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 geovetenskapSammanfattning : 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
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 geovetenskapSammanfattning : 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
3. Effects of Diclofenac on Fish Behavior : A Meta-Analysis
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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
4. Behavioural effects on Lymnaea stagnalis following sublethal exposure to the antidepressant fluoxetine
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : The use of selective serotonin reuptake inhibitors (SSRI), a group of antidepressants, increases globally resulting in higher concentrations also in wastewater recipients. These concentrations may cause altered behaviour of aquatic organisms and have effects on whole ecosystem level. LÄS MER
5. Assessment of embryotoxicity of the antiandrogenic drugs flutamide and bicalutamide in zebrafish (Danio rerio)
Master-uppsats, Uppsala universitet/Institutionen för farmaceutisk biovetenskapSammanfattning : Introduction: Prostate cancer is the most common type of cancer in Sweden and is often treated using antiandrogenic drug therapy. Two substances belonging to this class of pharmaceuticals are bicalutamide and flutamide. After excretion from the human body, the drug molecules enter the wastewater treatment plant (WWTP). LÄS MER
