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.
