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

    Sammanfattning : 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. LÄS MER
