1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : 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. READ MORE

2. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : 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. READ MORE

3. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS
University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskapAbstract : 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. READ MORE

4. Effects of Diclofenac on Fish Behavior : A Meta-Analysis
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : 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. READ MORE

5. Assessment of zebrafish embryo toxicity of environmentally relevant antibiotics
University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologiAbstract : Antibiotics are essential drugs in modern medicine. After consumption antibiotics are excreted in unmetabolized form in the urine and reach our sewage treatment plants (STP). STP are not able to degrade all antibiotics leading to release of antibiotics into the aquatic environment. Aquatic animals are thus continuously exposed to antibiotics. READ MORE
