Effects on Mycorrhizal Fungi

We currently do not have any examples of studies examining the relationship of worms to mycorrhizal fungi. If you are aware of any research that would be appropriate for this section, please contact us.


Distribution and Invasion Patterns

  • Changes In Hardwood Forest Understory Plant Communities In Response To European Earthworm Invasions

  • Patterns of earthworm invasion and understory plant composition in lakeside northern hardwood forests.

  • Susceptibility of a Northern Hardwood Forest to Exotic Earthworm Invasion

  • Earthworms on Long Island
