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
