The persistence of piñon pine woodlands in near-future climates will depend on two important factors: (1) the occurrence of favorable conditions for successful seedling recruitment and (2) genetic variation within populations that allows them to be adaptable to novel, future conditions. This dissertation consists of three studies designed to shed light on each of these two mechanisms. In one study, I followed a cohort of seedlings during a natural recruitment pulse to test the drivers of seedling survival. In a second study, I sequenced RNA from five different tissue types, including haploid megagametophyte tissue, and assembled a multi-tissue reference transcriptome for piñon pine. I then developed an exon-capture probe array based on de novo transcriptomes. Finally, using this probe set along with original samples collected across the entire range of P. edulis, I described geographic patterns of population differentiation, standing diversity, and local adaptation.
