Special Thanks

This project would have not been accomplished without the assistance of Saundra Solum and the IT support staff of UW-La Crosse.

Of course the project never would have begun without the diligent instruction and inspiration of my Professor Dr. Sandland.  

I would also like to extend my gratitude to Dr. Robert Blakemore whose work, above all others, helped make my information more complete and extend my own limited knowledge of earthworms.  For more exhaustive information from Dr. Blakemore's work, please visit this site: A Series of Searchable Texts on Earthworm Biodiversity, Ecology and Systematics from Various Regions of the World.
