ACKNOWLEDGEMENTS:
We would like to thank Derek Pouchnik and Weiwei Du at the WSU Laboratory for Biotechnology and Bioanalysis for their help with the Sanger sequencing. We would also like to thank members of the Friesen lab past and present for their help and advice on this project. This work was supported by a National Science Foundation Postdoctoral Research Fellowship in Biology (NSF award 1812184) awarded to R. H. Petipas. We would also like to acknowledge that this work was done on the traditional land of the first people of the Palouse. The Nimíipuu (Nez Perce) Tribe and the Palus people continue to work, live, play, and honor the traditions of their ancient heritage in Eastern Washington. Additionally, our historical specimens were collected around Washington State, which is home to 37 federally recognized tribes (https://wsu.edu/about/land-acknowledgement/) and other non-federally recognized tribes. The people of these tribes continue to thrive today in Washington State and we acknowledge their careful stewardship of the land over time immemorial to the present day.
