A schematic illustration of invasive earthworm effects on ecosystems that were free of earthworms (left figure). Because of earthworm’s soil burrowing and litter feeding activities, earthworm-free ecosystems are dramatically altered after earthworm invasion. Previous meta-analyses have revealed shifts in plant communities in response to invasive earthworms (Craven et al., 2017), whereas earthworm effects are also known to enhance greenhouse gas emissions (Lubbers et al., 2013) and N-leaching (Bohlen et al., 2004). The research highlights shifts in soil biodiversity (a major component of terrestrial biodiversity) in response to invasive earthworms.
