Acknowledgments
This research originated as an NSF-funded Research Experience for
Undergraduates (REU) internship in the summer of 2018 as part of a
Macrosystems Biology grant #1340847. We thank S. Bridgham for hosting
S.H. Jones at the University of Oregon during his REU internship. We
thank the landowners of our common gardens - Hazel Dell = D. Blair and
Horse Rock Ridge = Bureau of Land Management (BLM) - and source
collection sites - French Flat and Lower Table Rock = BLM, Jefferson =
M. and J. Krautmann, Sublimity = the Frauendiener family, Upper Weir =
U.S. Army, Whetstone = The Nature Conservancy - for granting access to
their properties for the purposes of this study. P. Bierzychudek and M.
Metz of Lewis & Clark College provided laboratory space for seed
preparation. Z. Wender and L. Boyer assisted in seed collection, Z.
Wender and A. Ludden assisted in seed preparation. A. Nelson, B. Johnson
and N. Merz assisted in seed planting at the common garden sites. This
manuscript would not have been possible without the input and assistance
of G. Jones during the data wrangling phase pre-analysis. The authors
would also like to acknowledge that this study took place on the
traditional homelands of the Confederated Tribes of Grand Ronde, whose
connection to the Willamette Valley and surrounding land remains strong
despite their forced removal to the Grand Ronde Reservation in the
1850’s (Leavelle 1998).
