Wood, DA, AG Vandergast, KR Barr, RD Inman, TC Esque, KE Nussear, RN Fisher. 2012. Comparative phylogeography reveals deep lineages and regional evolutionary hotspots in the Mojave and Sonoran Deserts. Diversity and Distributions. doi: 10.1111/ddi.12022
We explored lineage diversification within desert-dwelling fauna. Our goals were 1) to determine whether phylogenetic lineages and population expansions were consistent with younger Pleistocene climate fluctuation hypotheses or much older events predicted by pre-Pleistocene vicariance hypotheses, 2) to assess concordance in spatial patterns of genetic divergence and diversity among species, and 3) to identify regional evolutionary hotspots of divergence and diversity and assess their conservation status.
