CREDITS and DISCLAIMERS


Credits for this Experiment:    We first came up with the idea for this project when we observed distinctive patterns of establishment (or lack of establishment) of broadleaved tree seedlings beneath Eastern Hemlock trees as compared with that beneath other species (e.g. Sugar Maple, American Beech) in the same forest. Encouraging our students to make observations that will allow them to discover the same patterns has become the introduction to the "lab". Once the patterns seem evident, students are challenged to gather evidence to support or refute this hypothesis, and then to follow up with experiments that will help elucidate the underlying reasons for the observed differences in seedling establishment. We are greatly indebted to our former graduate school instructors, Drs. Peter Feinsinger, Jim Dole, Martha Crump, Jack Kaufmann, Jane Brockman, and Archie Carr for modeling exactly this kind of guided inquiry (stimulated by an initial, intriguing observation) to us in the graduate courses we took from them, long before anyone was calling it by that name.

   This submission was greatly improved by comments from anonymous reviewers.
