Abstract
Pinus aristata Engelm., Rocky Mountain bristlecone pine, has a narrow geographic and elevational distribution and occurs in disjunct mountain-top populations throughout Colorado and New Mexico in its core range. The species' unique aesthetic and ecological traits combined with the threats of the exotic disease white pine blister rust (WPBR), climate change in high elevation systems, and an outbreak of a native bark beetle make P. aristata of conservation interest, however, little is known about the species genetic structure or adaptive capabilities. Genetic diversity is the foundation for a population's adaptive capacity and knowledge of genetic diversity, population structure and geographic distribution of quantitative traits for this species will help guide gene conservation strategies and evaluation of risk among geographic regions.
