  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

  2. 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

  3. 3. Extraction efficiency of four pesticides using the QuEChERS extraction method and analysis by HPLC/DAD

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Honia Rasul; [2022]
    Nyckelord :analytical chemistry; pesticides; QuEChERS; soil; Chemistry;

    Sammanfattning : A cleanup step is essential from an analytical perspective, to improve the chance of quantification and to minimize interference. Pesticides in soil are a necessity is agriculture for survival of crops and protection from unwanted growth and pests. LÄS MER

  4. 4. Ökad andel neonikotinoidbetad rapsareal visar ingen generell negativ effekt på förekomst av vildbin i Sverige

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Joakim Mathiasson; [2021]
    Nyckelord :Agriculture; Neonicotinoids; Pollination; Rapeseed; Seed treatment; Wild bees; Betningsmedel; Jordbruk; Neonikotinoider; Pollinering; Raps; Vildbin;

    Sammanfattning : Under 2013 förbjöds behandling av blommande grödor med de systematiska neonikotinoiderna imidakloprid, klotianidin och tiametoxam i EU. Ett flertal studier och rapporter hade visat att pollinerande biarter kan uppleva subletala effekter av att konsumera neonikotinoid. LÄS MER

  5. 5. An assessment of the risk of neonicotinoid pesticides to harm non-target insects - is current risk assessments sufficient?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Elin Ingersdotter; [2016]
    Nyckelord :neonicotinoids; clothianidin; solitary bee; solitary wasp; risk assessment; pesticides; Earth and Environmental Sciences;

    Sammanfattning : Neonicotinoids, e.g. clothiandin, imidacloprid and thiamethoxam, is the most used class of insecticides worldwide. However, lately, this group of insecticides has been subject to controversy. LÄS MER
