Recent Population Genetic Divergence in Two Globose Cacti Endemic to the Queretano–Hidalguense Desert, Mexico
Mammillaria parkinsonii and M. perbella are species endemic to the Queretano–Hidalguense Desert (QHD), a potential globose cacti Pleistocene refuge. We tested if the phylogeographic and genetic structures of these species are temporally consistent with the Pleistocene glacial refuge hypothesis. In this case, there woul...
