    We quantified genetic diversity and gene flow among eight populations of Reaumuria soongorica in Inner Mongolia, China. Our results showed that genetic differentiation of R. soongorica across the Inner Mongolian plateau is primarily clinal in nature and is driven primarily by differential landscape resistance across areas with changing patterns of seasonal precipitation, perhaps as a result of differential timing of reproductive phenology along precipitation gradients. Finding that seasonal patterns of precipitation, and not temperature, drive population connectivity and gene flow may have important implications for predicting the effects of climate change on this keystone foundation species and devising effective strategies to utilize it in restoration efforts to ameliorate ongoing desertification in the region. Genetic diversity was highest in the western part of the sampled population, perhaps indicating that this region has historically harbored the highest effective population size of the species or may have served as the source of recent range expansion to other parts of the sampled range which exhibited lower genetic diversity. Understanding the ecological drivers of these relationships might be critical to resolving the causes of the geographical pattern of diversity, and could be important in understanding the ecology of the species sufficiently to anticipate climate change effects and effectively implement management strategies to restore the species and combat desertification.
