European earthworms have colonized extensive areas of the northern forest that were originally devoid of these large, soil-mixing ecosystem engineers. As originally described by Charles Darwin, earthworms can profoundly affect soils and the biological community.
What are the possible implications of exotic earthworm invasions for the health, biodiversity and greenhouse gas emissions of northern forests? How will the earthworm invasions proceed into the future? This lecture will provide a synthesis of what is known about these and other questions pertaining to the ongoing process of earthworm invasions.
