1. 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 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

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

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Malin Sjöberg; [2023]

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

   Abstract : 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. READ MORE

5. 4. The role of wood ants (Formica rufa) in the Arctic tundra and how climate change may alter this role

   University essay from

   Author : Michael Meijer; [2020]
   Keywords : Wood ants; ants; mounds; climate change; arctic tundra; ecosystem; ecology; vegetation; arthropods;

   Abstract : In the Arctic tundra, wood ants play an important ecological role in aerating the soil, cycling nutrients, for seed dispersal and, as biological control by preying on forest pest insects during outbreaks. The increase in temperature, caused by climate change, is positively associated with ant abundance. READ MORE
