Speciation, population structure, and demographic history of the Mojave Fringe‐toed Lizard ( Uma scoparia), a species of conservation concern
Abstract The North American deserts were impacted by both Neogene plate tectonics and Quaternary climatic fluctuations, yet it remains unclear how these events influenced speciation in this region. We tested published hypotheses regarding the timing and mode of speciation, population structure, and...
