GLIN==> earthworms




   I'm looking for researchers who may have studied the impact of earthworms 
on the duff layer of  northern forests, particularly in Michigan.  The 
Smithsonian has a recent article about earthworms as an exotic species that 
affects life on the forest floor. It says their destruction of the duff layer 
has been documented in Michigan, Minnesota, Wisconsin, New York and Canada. 
I'm developing a Michigan angle for a news story. Any worm experts out there?
  I can be contacted offlist at poulsondave@aol.com
