Abstract
The Mentzelia marginata complex consists of three species endemic to the Colorado Plateau, including the widespread species, M. cronquistii. The Colorado Plateau consists of complex geographical features that can allow gene flow within populations or prohibit migration between populations. We utilized phylogeographic techniques and ecological niche modeling to assess the effects of the landscape of the Colorado Plateau on M. cronquistii. We tested for evidence of independent evolutionary trajectories within the members of the marginata complex using the plastid matK and nuclear ribosomal ITS regions. Ecological niche modeling and populations of high genetic diversity identified areas within the Grand Canyon and northeastern Colorado Plateau that served as glacial refugia for M. cronquistii. We recovered evidence of independent evolutionary lineages in the members of the M. marginata complex; however, further investigation is required to elucidate the patterns of gene flow across the Colorado Plateau in M. cronquistii.
