“…Furthermore, providing firm divergence‐time estimates for the major clades and species within Cylindropuntieae could aid in our understanding of their use and potential dispersal by Pleistocene mammals such as Nothrotheriops shastense Hoffstetter (the extinct shasta ground sloth), and Neotoma spp. (packrats or woodrats; Thompson et al., ; Jansen, ; Van Devender, ; Betancourt et al., ), as well as their broad prehistoric and historical use by humans (Diguet, ; Bravo‐Hollis and Sánchez‐Mejorada, ; Felger and Moser, ; Minnis, ; Reinhard and Hevly, ; Hodgson, ; Riley, ). Lastly, the development of a robust diploid phylogeny will enable us to more rigorously test parentage of putative auto‐/allopolyploids in the group (see Baker and Pinkava, , , ; Mayer et al., , ; Pinkava, ; Baker and Cloud‐Hughes, ).…”
