  4. 3. 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 geovetenskap

    Author : Joel Fransson Forsberg; [2023]
    Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Abstract : 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

  5. 4. An evaluation of the Janzen-Connell hypothesis for a dry tropical forest in Guinea-Bissau

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Petya Petrowa Kirjazow; [2023]
    Keywords : Earth and Environmental Sciences;

    Abstract : The Janzen–Connell hypothesis states that seedling survival increases with distance from the parent tree, which promotes regular spacing of species within a forest and thus biodiversity. Very few studies have tested this hypothesis in tropical Africa. READ MORE
