  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. Animal personality in ants : Does the red wood ant (Formica rufa) express personality traits?

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

    Författare :Malin Sjöberg; [2023]
    Nyckelord :Animal personality; Scototaxis; Formica rufa;

    Sammanfattning : A recent theory within behavioural ecology suggests that some animal behaviour traits are consistent over time and over different contexts as part of an animals’ “personality”. Animal personality has generally been accepted within vertebrates, but the idea of invertebrates expressing personality has long been meet with scepticism. LÄS MER

  5. 4. Tragic Tales of ‘Victims’ and ‘Villains’ – A Study on Narratives and Emotions in Danish Rape Trials

    Master-uppsats, Lunds universitet/Sociologi; Lunds universitet/Sociologiska institutionen

    Författare :Kristine Louise Kristensen; [2023]
    Nyckelord :narrative; trial; rape; emotion; genres; story characters; rape myths; court ethnography; Law and Political Science; Cultural Sciences; Social Sciences;

    Sammanfattning : Given the fact that rape is difficult to prove in court and trials primarily are based on the defendant’s word against the plaintiff’s, it becomes highly significant to study the narratives about rape presented in criminal trials. This thesis is an ethnographic-inspired study conduct-ed in Danish courts from January to May 2023. LÄS MER

  7. 5. Exploring the impact of Formica exsecta ants on soil properties above the tree line in northern Sweden

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

    Författare :Filip Pekkari Juto; [2023]
    Nyckelord :Formica exsecta; ant mounds; soil properties; organic matter content; tundra;

    Sammanfattning : Ants are considered ecosystem engineers due to their effect on the soil properties and their ability to alter the flow of energy and nutrients. Many studies have focused on ants in boreal forests,but few have focused on the ant’s effect on the tundra. LÄS MER
